Vendor compliance
What Erewhon expects on every purchase order and invoice, where vendors lose time getting paid, and how to get fully compliant without adding a person to do it.
Quick answer
Erewhon's published purchase order terms require every invoice to carry the correct Erewhon PO number for each item, to match the PO price in the same units, and to be issued on or after delivery. Invoices that don't comply can be rejected or paid late. OrderSync reads Erewhon POs and sends invoices that match them, by EDI or email, exactly as your Erewhon AP contact specifies.
Erewhon has been tightening how vendors submit invoices, and payment depends on getting it right. Send us the instructions your Erewhon AP contact gave you and a recent Erewhon PO. We'll show you exactly how OrderSync would handle them, and get you sending compliant invoices automatically.
Erewhon publishes its Purchase Order Terms & Conditions and incorporates them into every electronically received Erewhon PO. The parts that decide whether you get paid on time:
Supply against an Erewhon PO
Erewhon only accepts goods ordered on its standard purchase order. Any change to a PO counts only if Erewhon authorizes it in writing.
Ship what the PO says
Quantity, quality and specification must match the PO. Deviations need Erewhon's written approval.
Invoice on or after delivery
Invoices are issued on or after delivery of the goods, and go into Erewhon's accounts payable system.
PO number on every item
The correct Erewhon PO number must appear for each invoiced item, with a product description.
Price in the PO's units
Each invoice must match the PO price in the same units shown on the PO.
Non-compliant invoices wait
Invoices that don't comply may be rejected or paid late. Erewhon can also set off amounts you owe it against what it owes you.
None of these are exotic. They're what happens when the invoice is built separately from the PO it answers.
Erewhon's terms ask for the PO price in the PO's units. If the PO is written in eaches and your system invoices by the case, the total can be right and the invoice still won't match:
| Qty | Unit | Price | Total | |
|---|---|---|---|---|
| PO line | 24 | Each | $3.25 | $78.00 |
| Invoice that matches | 24 | Each | $3.25 | $78.00 |
| Invoice that doesn't | 2 | Case (12) | $39.00 | $78.00 |
Illustrative figures. Check the unit on each of your own Erewhon POs.
Orders taken by phone or through a rep without a PO, two POs combined on one invoice, or a long PO number retyped by hand (or turned into scientific notation by a spreadsheet). Copy PO numbers from the PO itself; never rekey them.
Erewhon's terms say invoices are issued on or after delivery. If your invoice prints with the pick ticket and the store reports a short or a substitution, the invoice no longer matches what Erewhon received, and correcting it costs more time than waiting would have.
If you deliver to several Erewhon stores, keep one invoice per PO and per store, even when the deliveries go out on the same truck. Combined invoices are hard to match to anything.
Some Erewhon vendors trade by EDI. Others receive POs as documents and submit invoices by email. Erewhon decides which, and can change it. OrderSync handles both from one place, so a change in Erewhon's instructions is a configuration change for us, not a new process for your team. If you sell to retailers that require EDI, our retailer compliance guides and the grocery EDI guide cover them, and the free EDI Inspector will parse any X12 file you need to check.
Erewhon POs in, without retyping
Whether Erewhon's POs reach you by EDI or as documents, OrderSync reads them and creates the order in your ERP, accounting system or store, store by store.
Invoices that match the PO
The invoice is built from the PO it answers: the same PO number, the same items, the same units. Nothing goes out without a valid PO attached to it.
Delivered the way Erewhon asks
EDI 810, PDF by email, or both. We configure the format, the destination and the one-invoice-per-document rules to match the instructions your Erewhon AP contact gave you.
Sent after delivery, not before
Invoices go out once delivery is confirmed, on the delay you set, so shorts and substitutions are reflected before Erewhon sees the invoice.
A record of every send
Every invoice, when it went, and anything held back with the reason, so you can answer an AP question or a payment claim in a minute.
Is it worth automating?
If you have a few Erewhon orders a month and they already live in QuickBooks or Xero, probably not: fill in the PO number, match the units, and send it the way Erewhon asks. It pays off when Erewhon POs arrive as PDFs or EDI that someone keys into your system, and someone keys the invoice back out, store by store.
Erewhon runs 14 stores across Greater Los Angeles. The official starting points:
Erewhon issues purchase orders electronically, and its published PO terms apply to any electronically received Erewhon PO. How you receive POs and submit invoices depends on how Erewhon has set you up as a vendor, so confirm the current method with your Erewhon buyer or AP contact. OrderSync handles both EDI and emailed documents.
Under Erewhon's published PO terms, the correct Erewhon PO number for each invoiced item with a product description, and prices that match the PO in the same units. Invoices are issued on or after delivery and go into Erewhon's accounts payable system.
Follow the instructions from your Erewhon AP contact. Erewhon sets the submission method for its vendors and has been tightening how invoices are submitted. If you have instructions you're not set up to follow, OrderSync can configure invoicing to match them.
Erewhon's PO terms say invoices that don't comply may be rejected or processed late. The usual causes are a missing or wrong PO number, prices in different units from the PO, and invoices sent before shorts or substitutions were accounted for.
Yes. OrderSync reads incoming Erewhon purchase orders and sends invoices that match them, in the format and to the destination Erewhon specifies, one per PO and store, after delivery is confirmed.
