What Is an OMS? Order Management Systems Explained

Without one, a single transposed quantity can turn a 200-case order into a 2,000-case shipment and trigger a chargeback that wipes out the margin on the whole account. The differentiation in modern B2B isn't whether you can process EDI. It's whether you can process the long tail of non-EDI orders without hiring an army of data-entry staff.

You have orders coming in from six different places. EDI from Walmart. PDF purchase orders from regional accounts. Emails with Excel attachments from your newest buyer. Someone on your team is copying line items from each source into your ERP by hand, and yesterday a transposed quantity turned a 200-case order into a 2,000-case shipment. The customer is furious, and you're eating the freight cost on the return.

This is the exact problem an OMS is built to solve. This guide covers what an OMS is, how the order management process works, how B2B differs from B2C, cloud vs. on-premise considerations, and how to choose the right system for your operation.

OMS Meaning: What Does OMS Stand For?

OMS stands for Order Management System. An OMS is software that captures, tracks, and manages orders from the moment they arrive through fulfillment and invoicing. It acts as the central hub between your sales channels and your warehouse or ERP.

In B2B operations, supply chain management, and retail, OMS refers specifically to order management software that handles the full order lifecycle. According to Gartner's glossary, an OMS coordinates the order-to-cash process across channels and fulfillment locations. For B2B companies, that means managing purchase orders from trading partners, validating them against product catalogs and pricing rules, and routing clean data downstream.

The term has been around since the early days of electronic commerce. But the scope has grown. A modern order management system doesn't just log orders. It normalizes data from multiple formats, validates against business rules, allocates inventory, routes to the right warehouse, and tracks everything through delivery and payment settlement.

Key standards that define how data flows through an OMS:

• ASC X12 transaction sets define the EDI purchase orders (850), invoices (810), and ship notices (856) that most OMS platforms must ingest from major trading partners
• GS1 US standards govern the GTIN and UPC product identifiers your OMS uses to match line items to your catalog without ambiguity

How the Order Management Process Works

Every B2B order follows a five-stage lifecycle, regardless of how it arrives or what system you use. Here's each stage, what happens, and where things typically go wrong.

Stage 1: Order Receipt and Capture

Orders arrive in different formats from different channels. An OMS pulls them all into one place. EDI 850 purchase orders from major retailers, PDF orders from mid-size accounts, CSV or Excel files from buying groups, manual orders entered by your sales team: they all land in the same queue with the same data structure.

Without this consolidation, your team is toggling between systems. One person handles EDI, another processes PDF orders, and nobody has a complete picture of what's due to ship today. Every separate channel adds complexity, and the overhead of switching between them slows your team down.

Stage 2: Order Validation

Before an order reaches your warehouse, the system checks it against your business rules:

• SKU verification: Does this product exist in your catalog? Is it active?
• Pricing checks: Does the price on the PO match the customer's negotiated rate?
• Quantity validation: Is the quantity a valid case pack multiple? Does it exceed credit limits?
• Ship date feasibility: Can you actually fulfill this by the requested date given current lead times?
• Customer account status: Is this account on hold, past credit terms, or flagged?

This is where manual processes break down. A human reviewing 200 orders per day will miss things. An OMS catches a price discrepancy on order number 187 just as reliably as it catches one on order number 3. According to APQC's supply chain benchmarking data, top-performing organizations process orders at 60% lower cost per order than bottom-quartile companies. The difference is process design and automation, not staffing.

Stage 3: Inventory Allocation and Order Routing

Your system reserves inventory against the order. If you're running multiple warehouses, allocation also determines which location fulfills the order based on proximity, stock levels, and shipping cost. If Costco and Target both send purchase orders for the same product and you only have enough to fill one, the system flags the conflict before your warehouse ships partial orders to both.

This step is where inventory management and order fulfillment intersect directly. Bad data from earlier stages causes real damage here: a wrong SKU means picking the wrong product, a wrong quantity means a short shipment or overshipment.

Stage 4: Fulfillment and Shipping

Pick lists are generated, warehouse staff pull the items, and everything gets packed according to the buyer's requirements. For retail orders, this often includes specific labeling, carton markings, and packing slip formats.

The carrier picks up the shipment, and your system generates a ship notice (EDI 856 for retail trading partners). If you're shipping to retailers like Walmart or Target, the ASN must be sent within a specific window or you'll face penalties.

Stage 5: Invoicing, Payment, and Reconciliation

After shipment, you bill the customer. B2B invoicing is more complex than sending a total:

• The invoice must match the PO and the shipment exactly (three-way match)
• Pricing must reflect negotiated terms, volume discounts, and any allowances
• For EDI trading partners, you send an EDI 810 invoice electronically
• Payment terms vary by customer (Net 30, Net 60, 2/10 Net 30)

Invoice discrepancies are one of the top reasons for payment delays. If your invoice doesn't match the PO line for line, the buyer's AP team kicks it back, and you wait another 30 to 60 days to get paid. When your order management process is clean from the start, reconciliation is straightforward. When it's not, your AR team spends hours chasing discrepancies.

Order Management vs. Order Processing vs. Order Fulfillment

These three terms get used interchangeably, but they refer to different scopes:

	Order Management	Order Processing	Order Fulfillment
Scope	End-to-end (receipt through payment)	Receipt through ERP entry	Warehouse pick, pack, ship
Starts when	Customer places an order	Order data arrives for entry	Validated order reaches warehouse
Ends when	Payment is collected and reconciled	Order is entered and acknowledged	Shipment is confirmed and tracked
Key metrics	Order-to-cash cycle time, perfect order rate	Entry time per order, error rate	Fill rate, on-time shipment rate
Systems involved	OMS, ERP, WMS, TMS	OMS or ERP order entry module	WMS, shipping/carrier systems

Order management is the umbrella. Order processing and order fulfillment are stages within it. If you're evaluating software, an order management system covers the full lifecycle, while order processing automation tools focus on eliminating manual data entry at the intake stage.

OMS vs. ERP vs. WMS: What's the Difference?

All three systems touch orders. Here's how they differ:

	OMS	ERP	WMS
Primary focus	Order lifecycle management	Financial and business operations	Warehouse operations
Core job	Capture, validate, and route orders	Accounting, procurement, HR, planning	Pick, pack, ship, receive
Order handling	Multi-channel order consolidation	Order entry and invoicing	Order fulfillment execution
Inventory view	Available-to-promise across locations	Financial inventory valuation	Bin-level warehouse inventory
Typical users	Order management, customer service	Finance, procurement, executives	Warehouse staff, shipping
Examples	OrderSync, IBM Sterling, Manhattan	SAP, NetSuite, Microsoft Dynamics	HighJump, Blue Yonder, 3PL systems

Most ERPs include basic order entry, but they're not designed to handle orders arriving in mixed formats from multiple channels. Try processing an EDI 850 from Walmart, a PDF purchase order from a regional chain, and an emailed spreadsheet from a small account, all through your ERP's native order entry screen. It's possible, but it involves a lot of manual work.

A WMS picks up where the OMS leaves off. Once the OMS validates an order and allocates inventory, the WMS manages the physical fulfillment: picking routes, packing stations, label generation, and loading. Some companies try to make their WMS do double duty as an OMS, but warehouse management systems aren't built to parse incoming orders or validate pricing against customer agreements.

The best setup is all three systems working together: the OMS captures and validates orders, the ERP handles financial records, and the WMS manages the warehouse floor. Data flows between them through ERP integrations and APIs.

B2B vs. B2C Order Management: Key Differences

Consumer order management is straightforward by comparison. A customer clicks "buy," the system captures a cart, charges a card, and routes a pick ticket. Pricing is the same for everyone. The format is always the same. Returns follow a standard policy.

B2B order management deals with a different set of problems:

• Negotiated pricing: Every account may have a different price list. A system that can't enforce customer-specific pricing will either slow your team down with manual checks or let pricing errors through to invoicing.
• Mixed order formats: Your largest retailer sends EDI. Your second-largest sends PDFs. A regional chain emails Excel files. You need one system to handle all of them through a single pipeline, not three separate tools.
• Compliance requirements: Walmart needs an EDI 856 ship notice with SSCC-18 barcodes. Target requires DPCI codes at the item level. Miss these, and you eat chargebacks of $500 or more per shipment.
• Approval workflows: B2B orders often require credit checks, inventory allocation holds, or manager sign-off before fulfillment.
• High line-item counts: A single B2B purchase order might contain 200 line items across 50 SKUs. That's a different scale from a consumer order with 3 items.

According to Forrester's B2B commerce research, B2B buyers increasingly expect the speed of consumer experiences, but the backend complexity of B2B fulfillment has not gotten simpler. The gap between expectations and operational reality is where B2B order management software earns its value.

Order Management Approaches Compared

Not every company handles orders the same way. Here's how the three main approaches stack up:

Factor	Manual Processing	Semi-Automated	Fully Automated OMS
Order intake	Staff reads and keys each order	EDI auto-processed; PDF/email still manual	All formats parsed and entered automatically
Validation	Human checks (error-prone at volume)	Basic EDI validation; manual checks for other channels	Rule-based validation on every order, all channels
Processing time	10-20 minutes per order	1-2 minutes for EDI; 10+ minutes for manual channels	Seconds for clean orders; minutes for exceptions
Error rate	2-5% per field	Less than 1% for EDI; 2-5% for manual channels	Less than 0.5% across all channels
Staffing	1 FTE per 40-60 orders/day	Fewer staff for EDI; same for other channels	1-2 staff managing exceptions for 200+ orders/day
Visibility	Fragmented across systems	Partial (EDI tracked; other channels in spreadsheets)	Single dashboard for all orders and statuses

The jump from manual to semi-automated typically happens when a company starts trading with a retailer that requires EDI. The jump to fully automated usually comes when order volume outpaces headcount or when chargebacks start eating margins.

Cloud vs. On-Premise Order Management

The deployment model matters, especially for distributed teams and growing operations.

Factor	Cloud OMS	On-Premise OMS
Upfront cost	Low (monthly/annual subscription)	High (license + hardware + setup)
Maintenance	Vendor handles patching, monitoring, backups	Your IT team handles everything
Scalability	Add users or capacity on demand	Requires hardware upgrades and planning
Updates	Automatic, included in subscription	Manual installs, often delayed or skipped
Remote access	Browser-based, works from anywhere	Requires VPN or terminal server
Integration	API-first, pre-built connectors common	Custom integrations, often middleware-heavy
Total cost (5 yr)	Predictable, often lower for SMBs	Lower per-year if fully amortized, but hidden costs add up

Neither model is universally better. On-premise still makes sense for companies with strict data residency requirements or deeply custom workflows. But for most B2B teams processing orders from multiple channels with distributed staff, the tradeoffs favor cloud.

According to Flexera's 2025 State of the Cloud Report, 89% of enterprises now use a multi-cloud strategy, and reducing infrastructure management overhead is consistently cited as a top driver. For mid-size B2B companies without large IT departments, offloading server management to a SaaS vendor frees up limited IT resources.

Common concerns about cloud OMS:

• Data security: Major cloud OMS vendors run on infrastructure (AWS, Azure, GCP) that meets SOC 2 Type II and ISO 27001. Your data is encrypted in transit and at rest. The real question is whether your in-house IT team can match the security posture of a dedicated cloud provider.
• Internet dependency: If your internet goes down, your cloud OMS is unreachable. Mitigate with redundant connections and ask vendors about offline caching.
• Vendor lock-in: Protect yourself by choosing a platform that allows data export in standard formats. Check contract terms and avoid multi-year lock-ins unless the discount is substantial.

Signs You Need an Order Management System

Not every company needs a standalone OMS. If you process 10 orders a day from a single channel, your ERP's built-in order entry probably works fine. But there are clear signals that you've outgrown that approach:

Your team is re-keying data. If someone is manually typing order information from one system (or document) into another, you're paying for that labor and absorbing the errors. According to a study published in the International Journal of Information Management, manual data entry in supply chain operations produces error rates between 1% and 5%. On 500 orders per week, that's 5 to 25 orders with mistakes.

You're processing more than 20 orders per day from multiple formats. EDI from one retailer, PDFs from another, emails from a third. Each format requires different handling, and at this volume, manual entry errors compound fast.

Order volume is growing faster than headcount. You landed a new retail account and volume jumped 40%, but you didn't hire 40% more operations staff. The gap creates backlogs, delays, and errors.

Chargebacks are eating into margins. Retailers like Walmart and Target impose chargebacks for late shipments, missing ASN data, and order accuracy failures. If you're paying $500 to $5,000 per incident, the ROI math on an OMS gets straightforward quickly.

You can't answer basic questions. How many orders are open right now? What's the average time from order receipt to shipment? Which customer has the most exceptions this month? If answering these requires pulling data from three different systems, you need a centralized order dashboard.

Your spreadsheet only one person understands. If your order tracking depends on a Google Sheet that only one team member fully maintains, that's a single point of failure. One vacation, one sick day, and your entire process stalls.

Small Business Considerations

Enterprise order management systems are built for companies with 50 warehouses and dedicated IT departments. If you're a smaller operation, you need a system that solves today's problems without creating new ones.

A small business OMS should do three things well: capture orders from every channel into one place, validate before data hits your ERP, and give you a clear view of every open order in a single dashboard.

Here's how the options break down by company size:

Type	Monthly Cost	Best For	Limitations
Spreadsheets	Free to $20/user	Fewer than 20 orders/day, single channel	No validation, no automation, error-prone at scale
Lightweight tools (Ordoro, inFlow)	$50 to $200	Small eCommerce or wholesale with simple workflows	Limited B2B features, weak EDI support
Cloud OMS (OrderSync, Cin7)	$200 to $800	B2B companies with mixed order formats and 50+ orders/day	May require setup assistance for EDI
ERP modules (NetSuite OMS, SAP Business One)	$1,000+	Companies already on an ERP that want built-in order management	Expensive, slow to deploy, tied to ERP vendor

According to Nucleus Research, the average ERP implementation costs 3 to 4 times the software license in consulting and customization fees. For most small B2B companies, a cloud-based OMS hits the right balance between capability and cost.

What to Look for in Order Management Software

The OMS market ranges from enterprise platforms costing six figures annually to lightweight tools built for specific use cases. Here's what actually matters.

Multi-Format Order Ingestion

This is the baseline requirement. If the software only handles one order format (EDI-only or manual-entry-only), it's a point solution, not an OMS. Look for systems that handle EDI, PDF, CSV, email, and web portal orders through a single pipeline. Test it with your actual order documents during the evaluation, not just the vendor's demo data.

Customer-Specific Business Rules

Your pricing, payment terms, and routing rules vary by account. The system needs to store and enforce these rules automatically. When an order from Customer A arrives, the software should validate against Customer A's contracted prices, apply their discount tiers, and flag anything that doesn't match.

Validation and Exception Handling

The system should validate orders against your product catalog, customer-specific pricing, and business rules before anything touches your ERP. When it finds problems, it should flag them for review without blocking the rest of your order queue.

Ask vendors: how does your system handle exceptions? If the answer involves a lot of manual steps, keep looking. The best systems show you exactly what triggered the exception (price mismatch, unknown SKU, invalid ship-to) so the fix takes seconds.

ERP Integration Depth

"We integrate with your ERP" can mean anything from a flat-file CSV export to a real-time API connection. Push for specifics. Does the integration sync orders, inventory, pricing, and customer data? Is it bidirectional? What happens when the ERP is down?

A direct connection that syncs orders to your ERP in real time is the standard to measure against. Anything involving nightly batch files or manual exports is a generation behind.

EDI Compliance

If you sell to major retailers, your order management system must support the core X12 transaction set: 850 (purchase order), 855 (acknowledgment), 810 (invoice), 856 (ASN), and 997 (functional acknowledgment). More than basic support, it needs to handle retailer-specific implementation guides. Walmart's 856 requirements are different from Target's, which are different from Costco's.

If you work with EDI data, our free EDI Inspector helps you parse and debug transaction files.

Reporting and Visibility

You need to see order status, processing times, exception rates, and customer-level performance at a glance. If the vendor says "we can build custom reports," that usually means the built-in reporting is weak. Look for dashboards that answer your top five operational questions out of the box.

Key Order Management Metrics

You can't fix what you don't measure. These are the metrics that matter most:

Metric	What It Measures	Top-Quartile Benchmark
Perfect Order Rate	Orders delivered complete, on time, damage-free, with correct docs	95% or higher
Order Cycle Time	Average time from order receipt to delivery	Less than 48 hours (non-custom)
Order Entry Time	Average minutes to enter one order into the system	Less than 2 minutes (automated)
Line Item Accuracy	Correct line items shipped / Total line items shipped	99.5% or higher
Order-to-Cash Cycle	Average days from order receipt to payment collected	Less than 35 days
Cost Per Order	Total order management costs / Number of orders processed	Less than $5 (automated)
First-Pass Yield	Orders processed without exceptions or manual intervention	85% or higher
Fill Rate	Percentage of ordered units shipped on the first attempt	95% or higher

If your order entry time is above 10 minutes per order, you're doing significant manual work. If your perfect order rate is below 90%, the root cause is almost always bad data entering the system at the order receipt stage.

Track these monthly. Set improvement targets quarterly. Even small gains compound: improving line item accuracy from 97% to 99% on 300 daily orders eliminates 6 errors per day, roughly 1,500 per year.

B2B Order Management Software Comparison

The market includes platforms with different strengths. Here's how several well-known options compare:

Feature	OrderSync	SPS Commerce	Conexiom	NetSuite OMS	Esker
EDI support (X12)	Yes	Yes	Limited	Yes (add-on)	Limited
PDF/email order intake	AI extraction	No	Template-based	Manual	Template-based
Multi-format pipeline	Single pipeline	EDI-focused	PDF-focused	Requires config	Document-focused
Customer-specific pricing rules	Built-in	Via ERP	Via ERP	Built-in	Via ERP
ERP integration	API + native connectors	API + connectors	API + connectors	Native (NetSuite)	API + connectors
Exception dashboard	Yes	Basic	Yes	Yes	Yes
Best for	Mixed-format mid-market	High-volume EDI	PDF-heavy operations	NetSuite shops	AP + order automation

Every vendor's capabilities shift with new releases. Validate current feature sets during your evaluation, especially around PDF extraction accuracy and ERP-specific connectors.

Choosing Based on Your Order Mix

If 80%+ of your orders are EDI: An EDI-first platform like SPS Commerce handles high-volume electronic transactions well. The trade-off: non-EDI orders still require separate handling.

If your orders are split across formats: This is where most mid-market distributors land. You have EDI from major retailers, PDFs from regional accounts, and spreadsheets from buying groups. A platform with AI-powered order automation that handles all formats in one workflow eliminates the patchwork of tools.

If you're already on NetSuite: The native OMS module keeps everything in one system. The drawback: handling non-EDI order formats typically requires custom SuiteScripts or third-party apps, and per-user licensing adds up for operations teams.

If you need AP automation too: Esker covers both PO intake and invoice processing. Verify that their order extraction accuracy meets your needs for B2B purchase orders, which tend to be more complex than invoices.

How AI Is Changing Order Management

Traditional order management software follows rules you define: if the order format is X, parse it this way. If the price doesn't match, flag it. This works well for structured data like EDI, but it falls apart when orders arrive as PDF attachments, handwritten faxes (yes, they still exist), or emails with inconsistent formatting.

AI-powered order automation takes a different approach. Instead of rigid templates, machine learning models read and extract data from unstructured documents the way a human would, but faster and without fatigue. A PDF purchase order from a new customer doesn't require template configuration. The AI reads the document, identifies line items, quantities, prices, and ship-to addresses, then maps them to your product catalog.

This matters most for B2B companies with a long tail of smaller accounts. Your top 10 customers might send EDI, but customers 11 through 200 send PDFs, spreadsheets, and emails. Automated order processing powered by AI handles both ends of that spectrum without separate tools or workflows.

The next evolution is predictive: AI that spots patterns in your order data and flags anomalies before they become problems. An order that's 10x the customer's usual volume might be legitimate, or it might be a data entry error on their side. An intelligent OMS surfaces these cases for review instead of processing them blindly.

Implementation: What a Realistic Timeline Looks Like

A common mistake is underestimating how long B2B order management software takes to deploy. Here's a realistic timeline for a mid-market operation with 100 to 500 orders per day:

1. Weeks 1-2: Discovery and scoping. Map your current order sources, formats, volumes, and business rules. Identify your top 10 customers by volume and document their specific requirements.

2. Weeks 3-4: ERP integration setup. Connect the order management system to your ERP. Test with sample data. Verify that item numbers, pricing, and ship-to data map correctly.

3. Weeks 5-8: Channel configuration. Set up EDI trading partner connections, configure PDF extraction rules or AI training, and establish email monitoring. Start with your highest-volume channel first.

4. Weeks 9-10: Parallel processing. Run the new system alongside your existing process. Compare outputs. Identify gaps in extraction accuracy or validation rules.

5. Weeks 11-12: Go-live and tuning. Switch to the new system as primary. Keep the old process available as a fallback for the first 2 weeks. Monitor exception rates and adjust rules.

For operations with heavy EDI requirements (selling to multiple major retailers), add 2 to 4 weeks for trading partner testing. Each retailer has their own EDI implementation requirements. For companies migrating from an on-premise system to cloud, plan for an additional 2 to 4 weeks of data migration and cleanup.

Getting Started

If you're evaluating order management software for the first time, start here:

1. Map your current order flow. Document every order source, format, and the manual steps involved in getting that order into your ERP. This is your baseline.

2. Count your daily orders and calculate the cost of the status quo. Count the labor hours on manual entry. Calculate your error rate and the cost per error (chargebacks, re-ships, credit memos). At 300 orders per day with a 2% error rate, you're looking at 6 errors daily. Each costs $50 to $300 to resolve. That puts annual error costs between $75,000 and $450,000.

3. Define your must-haves vs. nice-to-haves. Multi-format ingestion? EDI compliance for specific retailers? Real-time ERP sync? Rank them. If a feature prevents errors or saves daily labor, it's a must-have. If it optimizes something you do monthly, it can wait.

4. Test with real data. Any vendor worth considering will let you run your actual orders through their system. Send a PDF purchase order. Upload a CSV. If they won't let you test, that tells you something.

5. Prioritize time-to-value. A system that takes 3 months to implement is not built for smaller operations. Look for platforms you can configure in days, not quarters.

If your orders involve EDI from retailers, our free EDI Inspector is a good place to start understanding your EDI data. For a broader look at EDI basics, check out our essential guide to EDI. And for a deeper dive into B2B-specific automation, see our B2B order automation software guide.

Frequently Asked Questions

What does OMS stand for in business?

OMS stands for Order Management System. It refers to software that manages the full lifecycle of customer orders: capture, validation, routing, fulfillment tracking, and invoicing. In B2B contexts, an OMS typically handles orders from multiple channels and formats, including EDI, PDF, and email.

What is the difference between an OMS and an ERP?

An ERP (Enterprise Resource Planning) system manages broad business operations including finance, HR, and procurement, while an OMS focuses specifically on the order lifecycle. Most ERPs include basic order entry, but lack the multi-channel ingestion, format-agnostic parsing, and order-specific validation that a dedicated OMS provides. Many companies run both, with the OMS feeding validated orders into the ERP. For a comparison of different order processing systems, see our dedicated breakdown.

What is the difference between an OMS and a WMS?

An OMS manages order data: capturing orders, validating them, allocating inventory, and tracking status. A WMS (Warehouse Management System) manages physical warehouse operations: picking, packing, shipping, and receiving. Think of the OMS as the brain that decides what needs to happen, and the WMS as the hands that execute it. In a well-designed operation, the OMS sends validated, allocated orders to the WMS for fulfillment.

What is the difference between order management and supply chain management?

Order management is one part of the broader supply chain. Supply chain management covers everything from raw material sourcing through production, warehousing, transportation, and delivery. Order management focuses specifically on the order lifecycle: capturing orders, validating them, fulfilling them, and settling payment. According to ASCM (formerly APICS), order management is one of the core processes in the Supply Chain Operations Reference (SCOR) model.

How much does order management software cost?

Pricing varies widely. Enterprise OMS platforms from vendors like IBM Sterling or Manhattan Associates can run $100,000 or more per year. Mid-market solutions typically range from $500 to $5,000 per month. Entry-level cloud platforms for smaller B2B operations start around $200 to $500 per month. Some platforms charge per transaction, others use flat-rate pricing. The right question isn't "how much does it cost?" but "what's the cost of not having one?" when you factor in manual labor, error rates, and chargebacks.

Can small businesses benefit from an OMS?

Yes, especially if you're processing orders from multiple sources or trading with retailers that require EDI compliance. A small supplier shipping to Walmart, Target, and Costco needs to handle EDI 850 purchase orders, send 856 ASN ship notices, and transmit 810 invoices, all in the correct format. An OMS makes that manageable without hiring a dedicated EDI team. The key is finding a platform sized for your volume and budget. The tipping point usually hits between 15 and 30 orders per day, or when you start receiving orders from more than two channels.

Is a cloud OMS secure enough for B2B order data?

Yes, for most B2B companies. Reputable cloud OMS vendors use enterprise-grade infrastructure with SOC 2 Type II certification, data encryption in transit and at rest, and regular security audits. According to Gartner's research on cloud security, through 2025 99% of cloud security failures were the customer's fault (misconfigured access, weak passwords), not the provider's.

How long does it take to implement an OMS?

A typical implementation for a mid-market B2B operation takes 8 to 12 weeks. This includes discovery, ERP integration, channel configuration, parallel testing, and go-live. Operations with heavy EDI requirements should plan for 12 to 16 weeks. Companies migrating from on-premise to cloud should add 2 to 4 weeks for data migration. The most common cause of delays is ERP integration complexity and trading partner onboarding.
