How to translate cryptic retailer codes into actionable operational opportunities
The essential shipment documentation to keep on file for successful deduction disputing
Why immediate action, ideally within the first 48 hours, is the best defense against revenue loss
For many emerging brands, deductions and chargebacks feel like a black box or unexpected revenue loss that eats into margins without warning. You shipped the products, billed the invoice, and yet a portion of your payment disappeared. While these deductions are common, they should be viewed as operational warning signs of issues further upstream. The first step is understanding terminology.
The first terms to define are chargeback and deduction. Some retailers use these terms interchangeably, while others use only one or the other, and others use them both for different things. In this article, we will define these terms in the following way:
Chargeback: This term is most often used to describe an additional charge invoiced to the supplier after the original shipment and invoice is paid, based on a real or alleged error on the supplier’s side.
Deduction: This term most commonly refers to an amount deducted from the original invoice based on a real or alleged error on the supplier's side (often a shipping shortage).
Whether a chargeback or a deduction, when you see one of them occur, it is important to treat it as a specific allegation that your shipment failed to meet the retailer's compliance standards. Because these penalties are often issued automatically by complex retailer systems that may lack context, the burden falls on the supplier to prove whether the error occurred at all. Suppliers make mistakes, causing chargebacks or deductions. But retailers can make mistakes, too, and impose invalid chargebacks or deductions.
When you see a chargeback or deduction, there are several steps you should take as soon as possible.

Step 1: Decoding the Charge
The first move in the first 48 hours is to understand where the charge or deduction is coming from. Every retailer uses a different taxonomy of codes. For example, Walmart has over 75 common accounts payable (AP) deduction codes. Reading the code correctly tells you exactly what kind of evidence you need to gather.
Common deduction categories include shortages, pricing discrepancies, and general compliance failures. For example, in Walmart’s system:
Code 11 indicates a price difference between the purchase order (PO) and the invoice.
Code 22 signals that goods were billed but not shipped, often triggered when an advance shipping notice (ASN) is missing or sent after delivery.
Code 25 is issued when Walmart claims no merchandise was received for an invoice, which requires a strong proof of delivery (POD) to dispute.
Target uses a different set of codes, such as:
A030 for carton shortages
A036 for cost differences
Even distributors like Sysco have their own version of overages, shortages, and damages (OS&D). Whether the code refers to a missing label, a late delivery, or a substituted item, it serves as a diagnostic tool for your supply chain.

Step 2: The Documentation Trail
Once you understand the reason for the chargeback or deduction, and have determined it is invalid, you must act fast to gather the documentation that proves your compliance. The challenge for many first-time suppliers is that the necessary evidence often needs to be captured at the time of shipment and can be difficult to find later.
Documentation is the backbone of the supply chain and the only way to successfully dispute an invalid deduction. A standard evidence kit for a dispute typically includes:
Purchase order (PO): The original contract of what was ordered and at what price
Invoice: A copy of what you billed the retailer
Bill of lading (BOL): This confirms the carrier picked up the goods
Proof of delivery (POD): A signed document confirming the retailer received the goods
Advance shipping notice (ASN): A timestamped record showing you sent the electronic data before the shipment arrived
For specific claims like shortages, you might also need pallet or carton photos with labels visible or carrier scan chains that show count continuity from pickup to delivery. If you are disputing a pricing error, you will need a date-stamped price file or an email from a buyer approving the cost change.
Step 3: Determining Validity
Not every chargeback or deduction is an error on the retailer's part. Before filing a dispute, you must honestly compare the claim against your documentation. If the chargeback is valid, then disputing it wastes time and can strain your relationship with the retailer.
For valid deductions, the next step is not recovery, but corrective action. This involves connecting the deduction to the internal process that caused it. For example, if you are receiving routing violations, you may need to update your internal instructions to match the retailer's latest routing guide. If you are getting shortage claims at a specific distribution center, you might need to audit that warehouse’s picking or palletizing process.
Step 4: Navigating the Portal
Every major retailer has a specific portal for handling disputes. For Walmart suppliers, this is the Accounts Payable Disputes Portal (APDP) located within Retail Link. In APDP, you can view the deduction code, the amount, and the associated documentation.
When submitting a dispute, the explanation should be professional, clear, and focused entirely on the facts. Avoid emotional language and use bullet points to point directly to the attached evidence. A simple "Code = Shortage. We delivered full and on time; evidence attached" is often more effective than a long narrative.
If a dispute is denied, do not assume it is the end of the road. Disputes are often denied due to incomplete documentation or filing against the wrong code. Some retailers will let you resubmit with more detailed evidence. Persistence frequently pays off in revenue recovery.
Step 5: Why the First 48 Hours Matter
Official dispute windows vary significantly across the industry. Some retailers allow 30 to 60 days, while distributors like McLane give you up to 90 days from the payment due date. However, others are far more restrictive. Sysco, for instance, requires a response to damage claims within 24 hours and shortage claims within 14 days.
The 48-hour timeframe is less about a universal legal deadline and more about the cleanliness of your evidence for disputing invalid deductions. The safest habit for a new supplier is to start the review the moment a chargeback or deduction appears rather than waiting for a monthly finance cycle. Documentation is much easier to locate when the shipment is fresh in everyone's mind. As time passes, the paper trail grows cold, and your ability to gather carrier affidavits or warehouse photos diminishes.
Acting immediately also helps when it comes to valid deductions, by helping you identify patterns before they become catastrophic. If you see a Code 22 today, you can investigate immediately. If you wait 30 days to look at the issue, you may have already sent four more weeks of shipments with the same error, multiplying your financial loss.

Building a Prevention Mindset
A mature deduction management program eventually shifts from defense to offense. By centralizing data, you can start to see patterns that individual disputes might miss. You can track metrics like your dispute recovery rate, the average cycle time for a dispute, and the recurrence rate of specific valid codes after you have implemented a fix.
Retailers often use vendor scorecards to track these metrics on their end. A scorecard provides a measurable look at your on-time delivery rate, order fill rate, ASN compliance, and sometimes more. By monitoring these yourself, not merely depending on the retailer, you can identify where you are flirting with penalties before they ever hit your invoice.
Protecting Your Bottom Line
Your first chargeback or deduction is a rite of passage in retail, but it doesn't have to be a permanent loss. By treating every deduction code as a piece of operational intelligence, you can recover revenue that was taken in error and tighten your processes to prevent future hits. The goal of a strong program is to build a feedback loop where every deduction makes your supply chain healthier over time.
