Your purchase orders arrive electronically.
Advance shipment notices go out.
Carton labels and invoices match.
Well, mostly, anyway.
“Mostly” might not show up until a few weeks later. I’ll be buried in a deduction on a remittance statement for a shipment that seemed fine when it left your dock, but didn’t check all the boxes. That’s a chargeback that hits your bottom line.
One shipment that misses a few critical EDI requirements might not be a big deal. But it’s never just one shipment.
Full EDI compliance is more than a technical detail tackled by your IT team. It’s an operational-level control that should be built into your WMS, not handled by second-hand systems or manual workarounds.
See the real cost of EDI compliance mistakes.
As a wholesale distributor, you’re probably serving multiple channels. And more and more, you’re seeing retail trading partners tightening EDI requirements. Each likely has their own routing guides, dictating how shipments have to look and move, along with required documentation.
Those mistakes can cluster around a few familiar places.
- Shipment notices go out late, or don’t match what’s actually shipped, so the retailers’ docks can’t reconcile the shipment when it arrives
- Carton labels are formatted incorrectly, missing a required field, further stalling receiving
- Invoices don’t match the original purchase order precisely, triggering manual disputes before payments clear
To be clear, none of these are dramatic, insurmountable failures on their own. But as you grow, the problems add up—particularly as you add new, larger retail partners with even tighter controls.
What EDI compliance means for B2B distributors.
EDI, or electronic data interchange, is the standard language retailers and distributors use on purchase orders, invoices and shipping documentation. Three document types carry most of the weight for a wholesale distributor: the 850 purchase order, the 856 advance ship notice and the 810 invoice.
Compliance means meeting a specific trading partner’s rules for how these documents are formatted, when they’re transmitted and how actual shipment aligns with the documents.
It sounds like a data entry problem, but the accuracy of an EDI document depends entirely on what happens at receiving, picking, packing and shipping.
Why? A retailer’s system doesn’t know the difference between a disciplined warehouse running up-to-date software and one strung together on spreadsheets, workarounds and employees with deep institutional knowledge. It can only measure whether the documents and the shipments match.
EDI accuracy matters more than ever in 2026 and 2027.
The global B2B ecommerce market is on pace to reach an estimated $36 trillion in 2026. That alone is straining electronic order processing platforms, as B2B and wholesale buyers expect the same speed and visibility they get as consumers.
As a result, the market for EDI software is expanding. Revenue in the sector is exploding, growing from $2.5 billion in 2025 to a projected $4.4 billion in 2030. More distributors are adopting EDI for the first time, because more and more retailers are demanding it and tightening requirements.
As routing guides and processing requirements grow less forgiving, deeper integration between EDI and warehouse management systems gets all the more critical.
Growing distributors feel the EDI pain.
Your WMS was likely built for one sales channel, so any EDI compliance is handled separately. Now, as you handle EDI retail orders alongside DTC storefronts, marketplace channels and other wholesale accounts, things start to slow down and conflict.
A mismatch in one channel can ripple into another. A picker working from a generic task list may not be informed individual orders have retail compliance requirements that a DTC order does not.
That creates problems down the line, and problems only grow as volume increases.
If you’re taking on new channels and wondering if your current WMS puts you at risk, there are a few quick ways you can check to see if your current workflows can handle EDI:
- Can EDI data flow directly into your WMS, or does someone have to re-key it?
- Can your system apply packing, labeling and routing rules by trading partner without complex custom scripting?
- Is your EDI order data visible to your reporting platform, or does it have to be imported manually by your team?
Most WMS platforms simply weren’t built for this kind of flexibility, locking distributors into workflows that don’t adapt to new sales channels, new requirements and new rules. As you evaluate a new WMS, a few capabilities matter most.
- Native EDI-ready order processing, not a bolt-on integration maintained by a third party
- Configurable, partner-specific rules for packing and routing that warehouse staff can easily update without code
- Clean separation between EDI wholesale orders and other channels to ensure compliance requirements stick to the right orders
- Native reporting that ties EDI activity back to the rest of your operation
- Complete visibility of all inventory and activity across channels
How InfoPlus puts wholesale distributors in control.
With the InfoPlus WMS, EDI-ready order processing comes standard. Retail compliance data stays connected to products, from intake through picking, packing and shipping. Your team never has to re-key data.
Line-of-business separation keeps wholesale, retail and DTC orders from blending into the same inventory pool, so compliance requirements tied to a real account are never buried in separate systems or spreadsheets.
Ready to reduce chargebacks? The bestl fix isn’t more oversight. It’s a warehouse management system built to handle the complexity you’re facing today, and whatever you might face tomorrow.
