Order Processing Software for B2B Distributors

Order processing software for B2B distributors automates the steps between receiving a customer purchase order and entering it into your ERP, handling EDI, PDF, email, and spreadsheet formats through a single pipeline. For B2B distributors, this means extracting data from purchase orders regardless of format, validating it against your item master and pricing, and syncing it to your ERP.

Research on B2B order processing costs and formats:

• APQC benchmarks put the median cost of manually processing a single B2B order at $5 to $15, with top performers using automation to bring that below $1
• The X12 standards body defines the 850 Purchase Order transaction that governs EDI-based orders from retailers like Walmart, Target, and Costco
• Gartner's supply chain technology research identifies AI-based order management as a top investment priority for mid-market distributors through 2027

Search for "order processing software" and you get a wall of ecommerce tools. Zoho Inventory. ShipStation. Ordoro. Fishbowl. These are good products, but they solve a different problem. They manage orders that come through shopping carts and online marketplaces.

If your orders arrive as EDI 850 purchase orders, PDF attachments, emailed spreadsheets, or phone calls, you need a different kind of order processing software entirely. This guide covers what to look for.

The Two Types of Order Processing Software

The market splits cleanly into two categories, and most comparison articles mix them together:

Type 1: Ecommerce Order Management

Tools like Zoho Inventory, ShipStation, Extensiv, and Ordoro. They sync orders from Shopify, Amazon, eBay, and other marketplaces into a central dashboard. They track inventory, generate shipping labels, and manage multichannel fulfillment.

Who it is for: D2C brands and ecommerce sellers who receive orders through online storefronts.

The assumption: Orders are already structured data. The customer clicked "buy," the cart captured every field, and the order exists as a clean record in the platform's database.

Type 2: B2B Order Automation

Tools like Esker, Conexiom, Workist, and OrderSync. They process purchase orders that arrive as documents: EDI files, PDFs, emails, CSVs. The software reads the document, extracts the data, validates it, and pushes it into the ERP.

Who it is for: Distributors, wholesalers, manufacturers, and suppliers who receive purchase orders from other businesses.

The assumption: Orders are unstructured or semi-structured documents. Someone has to read them and enter the data somewhere. The question is whether a person does it or software does it.

If you are reading this, you are probably Type 2. The rest of this guide is for you.

What B2B Order Processing Software Needs to Do

1. Accept orders in whatever format your customers send them

Your customers will not standardize. One sends EDI. Another emails a PDF. A third pastes line items into the body of an email. A fourth sends an Excel file every Tuesday.

You can ask them to change. They will not. Your software needs to handle the reality, not the ideal. This means multi-format processing: EDI, PDF, CSV, Excel, and email, all flowing through the same system.

2. Extract data without templates for every customer

Older document processing tools required you to build a template for each customer's PO layout. Map where the PO number field sits, where line items begin, how to parse quantities versus UOM. When the customer changed their format (and they always do), the template broke.

Modern systems use AI to read documents contextually. They identify line items, quantities, product codes, and ship-to addresses without a predefined map. This is the difference between spending a week setting up each new customer and onboarding them in minutes.

3. Validate before the order hits your ERP

Raw extraction is not enough. The software needs to check:

• Product matching. Does the customer's part number or description match something in your catalog? If they order "Widget A-100" and your SKU is "WDG-A100," the system should resolve that.
• Pricing accuracy. Does the price on the PO match the customer's contracted rate? If they are ordering at last quarter's pricing, that needs to be flagged before it syncs.
• Customer verification. Is this an active customer? Is the ship-to address on file? Are there any credit holds?
• Quantity sanity. Did someone order 10,000 units when they usually order 100? Catch it before it ships.

Without validation, you are just automating the creation of problems. Orders flow into your ERP faster, but they still have errors. Then you spend the same time fixing them downstream.

4. Integrate directly with your ERP

"Integration" in this context means the validated order creates a sales order in your ERP automatically. Not a CSV export. Not an API call that you have to build. Direct, out-of-the-box connection to your system.

The specific ERP matters. If you run NetSuite, you need a NetSuite integration. If you run SAP, QuickBooks, Dynamics 365, or a WooCommerce-based wholesale operation, the software needs to support your stack specifically.

Ask vendors this question early. "Integrates with major ERPs" on a marketing page is not the same as "we have a production integration with your specific ERP version."

5. Surface exceptions instead of hiding them

No system processes 100% of orders automatically. Some will have issues: a product code that does not match, a new ship-to address, a price discrepancy. What matters is how the software handles these.

Good order processing software routes clean orders straight through and sends exceptions to a review queue with clear context about what went wrong. Your team fixes the 5-10% of orders that need attention. The other 90-95% never require a human touch.

Bad order processing software either stops everything when one order fails, or worse, pushes bad data through silently.

The Current Landscape

Vendor	Tier	Best For	Format Support	ERP Integration
Esker	Enterprise ($50K-$200K+)	$100M+ revenue distributors	EDI, PDF, email	Deep ERP partnerships
Conexiom	Enterprise	Industrial/electrical distribution	EDI, PDF	Template-based
Workist	Mid-tier AI	European market, AI extraction	PDF, email, EDI	API-based
OrderSync	Mid-tier	B2B distributors, mixed formats	EDI, PDF, email, CSV, fax	Direct ERP sync
SPS Commerce	EDI-only	All orders arrive via EDI	EDI only	VAN-based

Here is how the main players compare for B2B order processing in more detail:

Enterprise-tier ($50K-$200K+/year)

Esker ranks for "order processing software" and "automated order management." They are a publicly traded French company with 316,000+ backlinks and deep ERP partnerships. Their product is real and proven. Their pricing is enterprise-only, starting around $50,000 per year with implementation fees on top. If you are doing $100M+ in revenue, they are a fit.

Conexiom focuses on sales order automation for distributors, specifically industrial and electrical distribution. Template-based document processing with ERP integration. Similar enterprise pricing. See how the two approaches differ in OrderSync vs Conexiom.

Mid-tier / AI-native

Workist is a German startup that ranks #1 for "automated order entry" and "ai order processing." AI-based document processing with a focus on the European market. Their product is strong but their pricing and sales motion are enterprise-leaning.

Nanonets is a general-purpose AI document extraction platform. Not specific to order processing, but you can configure it for PO extraction. You build the workflow yourself.

OrderSync processes EDI, PDF, email, and spreadsheet orders through a single AI pipeline with direct ERP sync. Built specifically for B2B distributors and suppliers in the mid-market. See how it works.

Legacy / EDI-only

SPS Commerce and TrueCommerce are EDI providers. They handle EDI transactions between trading partners. If all your customers send EDI, they work. If some customers send PDFs or emails (and some always do), you still need something else for those orders.

How to Evaluate Order Processing Software

Test with real documents: Do not evaluate based on a demo with sample data. Send the vendor five real purchase orders from five different customers: an EDI file, a clean PDF, a messy PDF, an Excel spreadsheet, and an email with order details in the body. See what the system extracts accurately without configuration.

Check the validation rules: Ask whether you can set a different price list per customer, and what happens when a product code does not match. If the answer involves manual workarounds or custom development, move on.

Measure the exception rate

After running real documents, ask what percentage of orders would have processed automatically (straight-through processing rate). For a well-configured system, this should be 85% or higher. If the vendor cannot tell you this number on your actual data, they are guessing.

Understand the pricing model

Some vendors charge per document processed. Some charge a flat monthly rate. Some charge per user. Per-document pricing punishes you for growing. Flat-rate pricing rewards it. Know the model before you commit, and project costs at 2x your current volume to see what scaling looks like.

Ask about onboarding time

Enterprise platforms can take 3 to 6 months to implement. AI-native platforms can onboard in days to weeks. If you need to be live before your next quarter, implementation timeline matters.

The Real Question

The question is not whether to automate order processing. Manual data entry at scale is unsustainable. The question is which type of solution fits your operation:

• If all your orders are EDI, a traditional EDI provider handles it.
• If your orders are mixed formats and you are doing $100M+ revenue, Esker or Conexiom are proven options.
• If your orders are mixed formats and you are a mid-market distributor, you need the AI capability without the enterprise price tag.

For that middle category, which is most B2B distributors and suppliers, the market is finally catching up. AI-based order processing automation at accessible pricing is what makes it possible to stop keying in orders without spending $100K on software.

FAQ

What is order processing software?

Order processing software automates the steps between receiving a customer order and entering it into your fulfillment or ERP system. In B2B operations, this includes document parsing (reading the PO), data extraction (pulling out line items, quantities, and prices), validation (checking against your catalog and customer data), and system sync (pushing the order into your ERP).

What is the best order processing software for small business?

It depends on how your orders arrive. If customers buy through an online store, ecommerce OMS tools like Zoho Inventory or ShipStation work well. If customers send purchase orders as PDFs, emails, or EDI files, you need B2B-focused automation like OrderSync, which handles multiple document formats and syncs to your ERP.

How much does order processing software cost?

Ecommerce OMS tools range from free tiers to $100-$500 per month. B2B order automation platforms range from mid-hundreds per month (AI-native startups) to $50,000-$200,000+ per year (enterprise vendors like Esker and Conexiom). The price usually correlates with the number of document formats supported, the depth of ERP integration, and the level of AI in the extraction engine.

What is the difference between an OMS and order processing software?

An OMS (order management system) is a broader category that includes order tracking, inventory management, and fulfillment routing. Order processing software specifically addresses the intake side: receiving purchase orders, extracting data from them, validating the data, and entering it into your back-end system. Many B2B operations need both, but the processing/intake step is where the most manual labor exists.

Can order processing software handle EDI and PDF orders?

Some can, most cannot. Traditional EDI solutions only process EDI. Traditional OCR tools only process PDFs (with templates). AI-based order processing platforms like OrderSync handle both plus email, CSV, and Excel orders through a single pipeline, eliminating the need for separate tools per format.
