Strong trading partner relationships have always been essential to business success. In today’s digital supply chains, those relationships increasingly depend on how well companies can meet EDI compliance requirements across every partner, workflow, and transaction.

EDI (Electronic Data Interchange) compliance is no longer just about exchanging a few documents correctly. It is about protecting revenue, reducing penalties, onboarding partners faster, and ensuring clean, compliant data flows into your business systems from every source, including traditional EDI connections and browser-based Web EDI portals. 

As part of a broader supply chain orchestration strategy, EDI compliance helps businesses coordinate execution across partners, systems, and workflows so issues can be identified and resolved before they disrupt orders, shipments, or cash flow.

What Is EDI Compliance? What Does Being EDI Compliant Mean? 

EDI compliance mandates are rules set by individual retailers and trading partners to standardize how they communicate with their supplier network. Each partner’s requirements are unique, based on the EDI transactions they use—such as purchase orders, acknowledgments, shipping notices, and invoices—and how quickly and accurately they expect to receive them.

By bringing more partners into a standardized digital process, retailers can reduce manual work, improve data accuracy, and make their supply chains more efficient. That includes not only fully integrated EDI partners, but also suppliers that need a simpler, browser-based way to participate through Web EDI.

For suppliers, meeting these requirements is critical. If you don’t comply, you could face:

• Costly chargebacks.
• Delays in payment.
• Negative impacts on vendor performance scores, which could strain your relationship with the retailer.

Bottom line: Non-compliance can lead to missed SLAs, financial penalties, delayed payments, lower vendor scorecard performance, strained business relationships, and fewer future business opportunities.

EDI compliance software is essential because many organizations require their partners to exchange documents electronically and meet strict performance standards, including retail giants like Walmart, Target, Costco, and Amazon.

In that sense, EDI compliance is not just a document exchange requirement. It is a foundational part of supply chain orchestration, helping businesses synchronize partner activity and keep execution aligned across the supply chain.

What are the Worst EDI Compliance Issues?

Many major companies have requirements for EDI trading partner setup and maintenance, both of which are important in keeping compliant.

EDI compliance can be tricky because each retailer has its own set of rules, and these rules can even change depending on how products are delivered (like directly to a store versus drop-shipped to a customer).

Suppliers often run into the following compliance challenges:

• The advance shipping notice (EDI 856) is incorrect, incomplete, or not sent on time.
• EDI invoices (whether the ) are rejected because they're incorrect or inaccurate.

• Suppliers fail to send a purchase order acknowledgements (EDI 855) within the required timeframe.

• Functional Acknowledgements (EDI 997) fail to send.

Common Compliance Requirements

Here you can see Walmart's "Getting Started with EDI Implementation Guide," which helps companies become compliant and trade EDI with Walmart. 

In the document, Walmart lays out 4 EDI compliance requirements for all partners

1. The ability to exchange the basic EDI document set
2. The timeline for EDI data testing
3. Connection requirements
4. Functional acknowledgment expectations 

First, the basic EDI documents required by Walmart are:

1. 810 Invoice
2. 821 Claim
3. 816 Address Listing
4. 820 Remittance
5. 850 Purchase Order
6. 864 Text Message [for invoice errors]
7. 997 Acknowledgment

Second, as far as the acceptable timeline for EDI testing, Walmart dictates that the period in which a vendor must prove that they are capable of transmitting all of the basic documents can take no longer than 6 weeks.

If testing takes longer than six weeks, the supplier may be removed from EDI testing for non-compliance.

Third, to trade EDI with Walmart, vendors must maintain a consistent AS2 connection. This means that a business must not go offline or experience any disruption in its communication with Walmart.

Since AS2 is the sole means of connecting to Walmart and the method by which EDI documents are exchanged, a drop in connectivity can negatively affect a trading partner's relationship with the giant. 

Fourth, the EDI trading partner MUST send EDI 997 functional acknowledgments no more than 24 hours from when Walmart purchase orders were placed in their partner mailbox.

In practice, true EDI compliance means supporting both highly integrated enterprise requirements and simpler web-based participation models so every relevant partner can operate within a compliant process.

Why Is EDI Compliance Important? 

With virtually all major trading partners requiring suppliers to be EDI compliant, the importance of building and maintaining compliance cannot be overstated, especially given its direct impact on margins, operational efficiency, and long-term customer relationships.

At its most basic level, EDI compliance means your business can exchange required documents accurately and on time according to each trading partner’s standards.

Solid, trust-based relationships built on being EDI capable foster confidence and business growth. EDI implementation issues are not only frustrating, but they can also be costly. And that cost of being non-compliant comes in the form of EDI chargebacks. 

True compliance is not just about the top tier of integrated partners. It is about extending compliant participation across your entire supply chain, including suppliers that rely on simple web portals instead of full EDI integrations.

What are EDI Chargebacks? 

EDI chargebacks are financial penalties for non-compliance with your trading partner requirements. Trading partners issue EDI chargebacks because of vendor non-compliance with agreed-upon elements of the Service Level Agreement (SLA). Because vendor non-compliance disrupts operations and creates additional expenses for the trading partner, the customer offsets those additional costs by issuing EDI chargebacks to the vendor. 

In the simplest terms, EDI chargebacks hit you because you caused mistakes that disrupted a customer's business operations and cost them money. If you're late with a delivery, packages are incorrectly labeled, or a shipment is damaged or incomplete, expect to receive an EDI chargeback.

Due to frequency of changes in routing guides, the complexity of managing dozens or hundreds of individual chargebacks, and the internal, cross-functional team effort required to combat EDI chargebacks, eliminating them entirely is often a tall order. Continue reading below to understand the different types of chargebacks and why they are assessed in the first place. 

Types of Chargebacks

EDI chargebacks can take many forms. The EDI 856 ASN (Advanced Shipping Notice) is no doubt one sort of EDI document transaction that most people reading this are familiar with.

The ASN is far and away the riskiest transaction for chargebacks.

Its primary purpose is to provide tracking and packing information ahead of delivery. As seen above, Walmart explicitly mentions the timely sending of ASNs as a key component of EDI compliance. 

Some of the most common elements included in an ASN are the purchase order number, ship notice number, and the location where the product will be shipped.

Beyond ASN errors, some other common reasons that B2B customers might execute an EDI chargeback to a vendor include:

• Using the wrong carrier
• Shipments arrive too early or late
• Key specs are missed (failure to meet proper packaging specifications, for example)
• Orders aren't filled at the appropriate rate
• Something's delivered to the wrong location
• Incomplete or incorrect paperwork 

See the graphic below for some example chargebacks Amazon extracts from non-compliant partners:

Top 3 Types of Amazon Vendor Chargebacks:

1. ASN Chargebacks: When using Fulfillment-by-Amazon (FBA), vendors must promptly send the Advanced Shipment Notification (ASN) to Amazon upon order receipt. It is crucial to adhere to the ASN protocol and meet the specified timeframe outlined by Amazon. Failure to comply or errors in shipping information will result in automatic chargebacks.
2. Routing Request Chargebacks: Upon receiving orders from Amazon, suppliers or vendors must accurately encode and submit routing requests within the shipping window. These requests enable Amazon to determine the shipping destination for the products. Failure to fulfill this requirement will lead to chargebacks.
3. Delivery Chargebacks: Timely delivery is essential. If orders are not delivered within the designated schedule, the products must be returned to Amazon. Failing to do so will result in order cancellation and financial penalties.

EDI Compliance Solution: Amazon

While every customer-supplier agreement is different, to offset unexpected expenses, EDI chargebacks levied by companies can range from hundreds to literally thousands of dollars per violation, adding up to huge - and avoidable -- revenue losses on an annual basis. 

While the consequences of non-compliance are clear, the bigger question is why so many companies still struggle to stay compliant. Recent survey data highlights several supply chain challenges that directly impact compliance:

Recent survey data highlights that 94% of businesses will experience regulation changes and/or enter new markets. As those requirements evolve, companies often need to adapt how they manage data exchange, compliance standards, and partner onboarding.

These are not just operational headaches. They are some of the same root causes behind EDI non-compliance, missed SLAs, shipping penalties, and chargebacks. Each delayed transaction, incorrect document, or visibility gap can show up as lost margin, lost trust, and missed opportunities.

The takeaway is clear: reducing manual work, improving data quality, and investing in technology that standardizes participation across integrated EDI, APIs, and Web EDI portals are essential steps toward protecting revenue and maintaining strong trading partner relationships. In a broader sense, they are also key to supply chain orchestration, ensuring businesses can move from visibility into coordinated action before issues escalate.

10 Proven Techniques for EDI Compliance

A successful EDI compliance strategy utilizes cutting-edge technology, clear communication, streamlined internal processes, and an ongoing commitment to development. Essential steps include:

1) Understanding Your Customers

Go through any vendor onboarding instructions and documentation provided by trading partners. Trading partners periodically revise their vendor guidelines, so it’s crucial to keep abreast of any updates to remain in adherence. Thus minimizing missed SLAs, costly fines, and negative vendor scorecards.

2) Attaining Adaptability

Creating cross-disciplinary teams allows businesses to better adapt and cater to customer demands. Incorporating key team members from various departments ensures a comprehensive understanding of company operations, processes, offerings, and skill sets that lead to greater innovation and success.

3) Incorporating Compliance Standards from the Start

To mitigate the risk of EDI compliance errors, weave compliance checks into daily operations rather than treating them as a final step in order fulfillment. This helps identify and correct issues earlier, before they turn into penalties or failed transactions. Ensure operational processes are designed with compliance in mind and that systems such as ERP, WMS, TMS, EDI, APIs, and Web EDI portals are set up to support those standards from the start.

4) Continuously Improving Business Processes

View evolving EDI guidelines as a chance to assess and improve operational efficiencies. This can turn a business cost into a business opportunity that improves processes. Encourage teams to actively contribute ideas, as individuals involved in daily operations frequently offer valuable feedback that can lead to meaningful improvements.

5) Establishing Performance Benchmarks

Develop key performance indicators (KPIs) for essential supply chain operations to identify areas of weakness. Leveraging an EDI compliance platform with strong visibility and analytics makes it easier to pinpoint underperformance, track SLA risk, and make informed decisions before issues turn into penalties.

6) Gaining Insights from Industry Pioneers

Optimize supply chain efficiencies by learning from trading partners. Adjustments to trading partner requirements often aim to maintain their competitiveness in dynamic markets, allowing businesses to leverage these insights for their own advantage.

7) Using Technology That Suits Your Needs

Many organizations are hindered by cumbersome, fragmented technology systems that require significant time and resources to manage. Prioritize EDI and compliance solutions that can support your full trading partner ecosystem, including integrated EDI, APIs, and browser-based Web EDI participation. Check out the top Web EDI providers here. 

8) Seeking Knowledge 

Trading partners often provide workshops on vendor compliance which can significantly boost compliance ratings, while simultaneously demonstrating a company’s dedication to the partnership. These sessions may also provide a sneak peek into forthcoming compliance updates, allowing businesses to better prepare for impending changes.

9) Communicating Regularly 

Regularly connect with trading partners to stay aligned with their requirements, strategies, operations, etc. This approach not only supports EDI compliance but also fosters a stronger business relationship that may lead to more business loyalty. 

10) Empowering Your Sales Force

It is essential for sales professionals to grasp the significance of the operational improvements achieved via compliance initiatives. This enables them to effectively highlight the benefits in their sales pitches. Consider hosting training sessions led by those who have a direct understanding of a company’s processes to give the sales team an invaluable perspective that can be used to attract potential customers.
