The short answer
Web EDI lets you exchange EDI documents in a browser, typing or reviewing data in web forms, with no EDI software to run. Integrated EDI connects trading partners directly to your ERP, so orders, ship notices and invoices flow automatically. Web EDI suits low volumes and few partners; integrated EDI pays off as volumes, partners and accuracy requirements grow.
Web EDI vs integrated EDI
| Criteria | Web EDI | Integrated EDI |
|---|---|---|
| How documents are handled | Viewed and created in web forms | Created and posted automatically in your ERP |
| Manual effort | Orders still re-keyed into internal systems | Minimal; people handle exceptions |
| Startup time and cost | Fast and low | Higher, depending on ERP and partners |
| Accuracy at volume | Declines as volumes grow | High, with validation against ERP data |
| Best fit | Few partners and low order volumes | Growing volumes or many partners |
Web EDI is fast and low-cost to start, but every order and response passes through people, so errors grow with volume.
People step in only when validation flags an exception. The trade-off is a larger initial project that depends on your ERP and your partners’ requirements.
Two ways to meet the same requirement
When a customer requires EDI, both approaches get you compliant. They differ in how much of the work stays manual.
How web EDI works
A provider hosts the EDI translation and partner connection. You log in to a web portal where incoming purchase orders appear as readable forms. You create acknowledgments, ship notices and invoices by filling in forms, often by turning the original order into a response so data carries forward. The provider converts your forms into compliant EDI and sends them.
Why companies choose it: fast to start, low cost, no software or EDI staff required.
The trade-off: orders still have to be entered into your own order, warehouse and accounting systems, and ship notices and invoices are typed or copied, which introduces errors as volumes grow.
How integrated EDI works
Integrated EDI connects your trading partners directly to your ERP and warehouse systems. Purchase orders become sales orders automatically; ship notices are built from actual pick, pack and label data; invoices come from ERP billing. People only step in when validation flags an exception.
Why companies choose it: accuracy, speed and scalability, plus fewer compliance penalties.
The trade-off: a larger initial project that depends on your ERP and partners’ requirements.
Signs it is time to integrate
- Staff spend hours a week re-keying orders or invoices.
- Chargebacks or deductions for ship notice or invoice errors are increasing.
- You are adding partners or programs, such as drop-ship.
- Peak seasons overwhelm manual processes.
A practical path
Start with web EDI to meet a first customer’s deadline, then integrate the highest-volume partners first. When both run on the same platform, moving a partner from web forms to integration can keep the same provider and partner connection. Expect the partner to test the documents your systems now generate, because their content and timing change.
