Retailer asked for EDI? Here’s what actually happens next

For many brands, the moment comes during a retailer conversation.

You finally land the opportunity you have been working toward. The buyer is interested, your product fits their shelves, and things seem to be moving forward.

Then the retailer says something that stops the conversation cold.

“We require EDI.”

If you are new to Electronic Data Interchange, that moment can feel overwhelming. Many companies immediately start searching online trying to answer questions like:

• What is EDI?
• Do I need special software?
• How long does it take to set up?
• Do I have to use the provider the retailer recommends?

The reality is that getting started with EDI is much more straightforward than most brands expect. Thousands of companies go through this exact process every year, and once you understand the steps, it becomes clear how manageable it really is.

In this guide, we will walk through exactly what happens after a retailer requires EDI, from the first conversation to going live with real orders.

What does it mean when a retailer requires EDI?

When a retailer requires EDI, they are asking you to exchange business documents electronically instead of using emails, faxes, or manual entry.

These documents typically include purchase orders, shipping notices, invoices, and inventory information. Retailers rely on EDI because it automates the flow of information between systems and dramatically reduces errors.

Instead of manually entering orders, their systems communicate directly with their suppliers’ systems through standardized documents.

Common EDI documents retailers require include:

• EDI 850 purchase orders
• EDI 855 purchase order acknowledgements
• EDI 856 advance ship notices
• EDI 810 invoices

If you are completely new to EDI, it helps to start with a foundational understanding of how the technology works and why retailers depend on it. You can explore a full overview of the process in this guide for companies that are new to EDI.

Once a retailer tells you EDI is required, the next step is simply figuring out how you will connect to their system.

Do you have to use the EDI provider the retailer recommends?

This is one of the biggest misconceptions in the EDI world. Retailers often suggest a preferred EDI provider or partner network. Many brands assume this means they are required to work with that specific provider.

In most cases, that is not true. 

Retailers care about receiving compliant EDI documents. They do not typically require suppliers to use a specific provider. As long as your EDI system can connect to the retailer and meet their requirements, you are usually free to choose the solution that works best for your business.

This flexibility is important because not all EDI providers offer the same capabilities. Some solutions focus only on document transmission, while others provide deeper integrations with your systems and workflows.

Choosing the right partner can have a major impact on efficiency, especially if you plan to scale into multiple retail channels.

If you are evaluating providers, it is worth reviewing what a modern EDI platform should include, such as integrations, automation, and retailer compliance tools. eZCom outlines this in detail in our overview of Lingo, our cloud-based EDI software.

What happens immediately after a retailer requires EDI?

Once a retailer confirms EDI is required, the onboarding process typically follows a predictable sequence.

First, the retailer will provide their EDI specifications. These documents explain the types of transactions required, formatting rules, communication protocols, and testing requirements.

At this point, you’ll choose an EDI provider to guide you through the process. It’s worth noting that you’re not always required to use a provider recommended by the retailer – you have the flexibility to choose a partner that best fits your needs. 

Next, your EDI provider will begin configuring the connection between your company and the retailer. 

During this phase, your provider maps the retailer’s document format to your internal system or workflow. For example, when the retailer sends an EDI 850 purchase order, it needs to be translated into a format that your team can easily process.

At the same time, your outgoing documents, such as shipping notices or invoices, are configured to match the retailer’s exact requirements.

This process ensures that both systems speak the same language.

How long does EDI onboarding take?

One of the most common questions companies ask is how long the process will take. The timeline depends on several factors, including the retailer’s testing process, their responsiveness, and how your internal systems are structured. However, with the right EDI partner, onboarding is often much faster than companies expect.

A typical onboarding timeline includes:

Retailer setup and configuration
Document mapping and workflow configuration
Testing with the retailer’s EDI team
Final certification and go-live

Many retailers have structured testing procedures to ensure documents flow correctly before production begins. Once testing is complete, the retailer approves the connection and real transactions begin.

How does EDI connect to your existing systems?

One of the biggest concerns companies have about EDI is whether it will work with their existing software.

Most businesses already rely on tools such as Shopify, QuickBooks, NetSuite, warehouse systems, or shipping platforms to manage orders and inventory. The good news is that modern EDI platforms are designed to integrate with these systems.

Instead of manually entering retailer orders, EDI can automatically push orders into your ERP, eCommerce platform, or warehouse management system.

This automation eliminates duplicate data entry and significantly reduces the risk of errors.

For companies looking to streamline operations, exploring EDI system integrations is an important step in building a connected order management workflow.

What does EDI testing involve?

Before any real transactions occur, many retailers require suppliers to complete a testing phase.

Testing ensures that your documents are formatted correctly and that the retailer’s system can process them without issues.

During testing, your provider will send the retailer sample documents such as purchase order acknowledgements, advance ship notices, and invoices.

The retailer reviews these documents and confirms they meet compliance standards.

If any adjustments are required, they are corrected before moving to the next stage.

While testing may sound complicated, it is a routine process handled every day by experienced EDI providers. Once testing is complete, your company is certified to transact electronically with the retailer.

What happens once EDI goes live?

After testing is approved, the connection moves into production. From that point forward, retailer transactions flow electronically through the EDI system. Purchase orders arrive automatically, acknowledgements are sent back, and shipping notifications and invoices are transmitted digitally.

For many companies, this is when the real value of EDI becomes clear. Instead of managing orders manually through emails and spreadsheets, the entire workflow becomes structured and automated.

As companies expand into additional retail partnerships, the same EDI infrastructure can support multiple trading partners. If you are planning to scale your retail channel strategy, this is where working with an experienced EDI provider becomes especially valuable. 

If you are currently evaluating providers or planning your first implementation, you can schedule a demo with an EDI expert to see how the process works in practice.

What if you already have EDI but want to switch providers?

Many companies start with one EDI solution and later realize it no longer meets their needs.

This often happens when businesses grow, add new retailers, or want deeper integrations with their ERP or warehouse systems.

Switching providers is more common than many companies realize, and it does not mean you have to restart the entire onboarding process.

Most retailers simply require the connection to be reconfigured and retested with the new provider.

If you are considering a change, eZCom has a detailed guide that explains what is involved in switching EDI providers and how companies make the transition smoothly.

The bottom line

Hearing that a retailer requires EDI can feel intimidating at first, especially if your company has never worked with the technology before.

But once you understand the process, it becomes clear that EDI onboarding follows a well established path. Retailers provide specifications, your EDI provider configures the connection, testing confirms compliance, and then transactions begin flowing automatically.

For growing brands, EDI is often the gateway to larger retail partnerships and scalable order management.

With the right partner, the process is not only manageable. It becomes a powerful foundation for long term retail growth.
