The Supplier's Guide to Retailer Deductions During Peak Season 

In this article, learn about: 

• Which Walmart, Target, and Amazon deduction codes pose the greatest risk during peak season 

• How ASN timing, shipment discrepancies, and retailer-specific compliance requirements contribute to deductions 

• What suppliers can check before peak volume to prevent costly chargebacks and improve dispute readiness 

Retailer deductions can become especially costly during peak season, when higher order volumes, tighter delivery schedules, and increased shipping activity put additional pressure on supplier operations. A missed advance ship notice (ASN), incorrect carton count, or delivery outside a retailer's required window can quickly translate into lost revenue. 

Walmart, Target, and Amazon each enforce their own compliance requirements, deduction codes, and dispute procedures. Understanding the differences helps suppliers identify recurring issues, correct errors before they affect additional shipments, and protect margins during the busiest months. 

This guide examines the deductions and compliance metrics suppliers should monitor at each retailer, and provides practical steps to reduce exposure before peak season. 

Why Do Holiday Season Retailer Deductions Rise at Peak Volume? 

Deductions can result from automated compliance systems, receiving discrepancies, audits, and other claims. 

More purchase orders (POs), ASNs, and cartons give those systems more records to compare, so even a steady error rate produces more deductions. 

Timing adds another layer. Target measures compliance based on when goods are received, rather than when they ship. A shipment that leaves in April, for example, could be evaluated in May under updated compliance requirements. During peak season, this distinction is important because shipments are subject to the requirements that were in effect when Target receives them. 

Across Walmart, Target, and Amazon, retailer deductions generally have five root causes:  

• Shipment shortages 

• Late or missed deliveries 

• ASN errors 

• Labeling and packaging violations 

• PO or invoice discrepancies 

Understanding these categories helps suppliers identify where deductions originate and which processes need attention.

Can One Late ASN Become Three Different Deductions? 

An ASN that is missing, late, or wrong falls in the ASN and electronic data interchange (EDI) root-cause category. Each retailer assigns a different code, clock, and penalty. 

For example: 

• Walmart: Code 22, Goods Billed Not Shipped, posts when the ASN is missing or late, because Walmart can’t match the shipment to the invoice. 

• Target: ASN Availability requires an error-free EDI 856 ASN before the trailer’s in-yard time. A miss costs $0.75 per carton, with a $100 minimum. 

• Amazon: An On-Time Non-Compliance (OTNC) deduction posts when the ASN transmits outside Amazon’s window, even if the freight arrives on time. Amazon generally expects the ASN within 30 minutes of departure. The other option is at least six hours before the delivery appointment. 

At Target, the most common availability failure is an accurate, yet late, ASN. Suppliers typically fix it by triggering the ASN from the shipment event in their EDI system instead of from a task list. 

Walmart Deductions During Peak Season 

Walmart uses more than 100 deduction codes, and three of them tie directly to ASN, shortage, and delivery-timing failures. 

Shortage and Delivery Timing Codes 

Suppliers should watch these codes first: 

• Code 22, Goods Billed Not Shipped: This code can arise when the quantity of an item on the invoice does not match the quantity of that item that was received. 

• Code 24, Carton Shortage: This code posts when the cartons received are fewer than the bill of lading (BOL) lists. 

• Code 99, On Time In Full (OTIF): Walmart fines 3% of the cost of goods sold (COGS) on non-compliant shipments. Any slip in the delivery window, including one from a crowded dock schedule, exposes the shipment to the fine. 

Avoiding them requires matching carton counts to the bill of lading (BOL) and sending the ASN before delivery. 

What a Surprise Deduction Surge Looks Like 

Serta Simmons Bedding faced three Walmart problems at once. Incorrect shipping methods in its EDI files triggered deductions that needed manual disputes. Walmart also made a complex settlement offer, and a $200,000 post audit arrived without warning. 

The case study does not tie these problems to a holiday season, but it shows how a surge builds from several directions. Historical records showed the audited network allowances had already been applied. Serta Simmons disputed the full $200,000 and won. Once SPS Commerce helped correct the EDI errors at the source, the recurring deductions stopped completely. 

Which Target Deductions and Metrics Matter at Peak? 

Target grades each PO against its compliance goals, so a mismatch on one peak shipment posts as its own deduction. 

Shortage and Deduction Codes 

Three codes anchor the shortage and Perfect Order exposure: 

• A030: A manual deduction for a carton shortage, issued when the invoice and the receipt differ mostly because cartons are missing. 

• A034: The unit-level shortage code. 

• A176: An automated Perfect Order Program deduction tied to late arrivals or fill-rate failures. Fill Rate Original requires at least 95% of the original PO’s item quantities to be delivered. 

Receipt-Date Measurement in Practice 

The 2026 Vendor Compliance Policy took effect May 3 and added two measures. Physical case pack Accuracy compares the physical case pack and store ship pack against the PO. An Item Attribute Audit at the DC checks dimensions and weights against Target’s item record. Both are graded on the receipt date, so every shipment received at peak is measured against them. 

For example, a supplier may ship 400 cartons whose ASN lists a case pack that does not match Target’s item record. At the flat $0.75 per carton Target applies to its ASN and barcode metrics, that one shipment costs $300, and the same mismatch repeats until the item data is corrected. 

The policy sits in Partners Online and not in a public announcement, so suppliers should double-check rates there. Target reports each metric separately in the Supplier Performance Management (SPM) Dashboard, and a weekly read catches a repeating defect early.

Amazon Deductions To Watch During Peak Season 

Amazon splits revenue loss into shortage claims and deductions. Purchase quantity variance (PQV) is the quantity-based shortage. 

A potential shortage posts when the quantity received does not match the quantity shipped. It works more like an alert, and an unresolved one escalates to a remaining shortage. 

For example, a supplier may invoice Amazon for 500 units of a seasonal item while receiving records show 480 units. Amazon then issues a 20 unit shortage deduction until the supplier proves the full shipment arrived.  

Suppliers should keep proof of delivery and the ASN timestamp together. Matching receipt dates to ASN timing is the first step in disputing a shortage.

How Can Suppliers Prevent Retailer Deductions Before Peak Season? 

Peak season preparation should include a review of the shipment data, compliance requirements, and documentation retailers use to validate orders. Suppliers can reduce recurring deductions by checking the following areas before order volume increases. 

Frequently Asked Questions 

Is a deduction the same as a chargeback? 

Deductions and chargebacks are not the same thing. A deduction is any amount a retailer subtracts from a supplier’s invoice payment, while a chargeback is a specific type of deduction typically associated with a compliance violation or operational error. 

How can suppliers prevent retailer deductions during the holidays? 

Most prevention is a data fix and not a shipping fix. Suppliers tie ASN timing to the shipment event, align item data between their systems and the retailer’s, and check ASN accuracy before the carrier picks up the shipment. 

Want To See Which Retailer Deductions Are Building Before Peak Hits? 

During peak season, even small compliance errors can generate significant financial losses when they repeat across hundreds of shipments. Identifying those patterns early helps suppliers address the underlying issues, prioritize disputes, and protect revenue. 

SPS Commerce Revenue Recovery helps suppliers gain greater visibility into retailer deductions, identify recurring issues, and recover revenue that might otherwise go unclaimed. With a clearer understanding of where deductions originate and how they affect the business, teams can spend less time investigating individual claims and more time addressing the issues behind them.
