Fee Audit

费用审核

After the 2024 size-tier reshuffle, dimensional-tier misclassification became the single most common hidden fee leak. Sellers also miss referral fee credits on refunded orders. This skill audits the Payments report for these specific anomalies and writes the FBA fee-discrepancy case per finding. Fee overcharges are disputed through Seller Support FBA Fee Discrepancies, not SAFE-T. SAFE-T reimburses sellers on certain refund and return claims, it is not the channel for FBA fee errors.
2024年尺寸等级调整后，尺寸等级分类错误成为最常见的隐性费用漏洞。卖家还会错过退款订单中的推荐费返还。本技能会审核支付报告中的这些特定异常，并针对每个问题撰写FBA费用差异申诉。费用超额收费需通过卖家支持的「FBA费用差异」渠道申诉，而非SAFE-T。SAFE-T仅针对特定退款和退货申请向卖家退款，并非处理FBA费用错误的渠道。

When to use this

使用场景

  • FBA fees feel high and the seller does not know which line is wrong.
  • A product is near a size-tier boundary.
  • High refund rate and not sure the referral fee was credited back.
  • Routine quarterly audit to catch silent fee creep.
  • FBA费用过高，但卖家不知道具体哪一行数据有误。
  • 产品接近尺寸等级边界。
  • 退款率高，但不确定推荐费是否已返还。
  • 例行季度审核，排查隐性费用增长。

The framework. The Five Fee Anomalies

框架：五大费用异常

Every Payments report contains one or more of these five patterns:
  1. Size-tier misclassification. The unit is billed at a higher size tier than its measurements warrant. Cross-check listed dimensions vs the FBA tier table.
  2. Missing referral refund. A refund was processed but the referral fee was not returned proportionally. Cross-check refund row vs the original sale.
  3. Duplicate fulfillment fee. Two FBA fees for the same order. usually a system error.
  4. Storage discrepancy. Monthly storage billed for units already removed or units in transit.
  5. Reimbursement gap. A reimbursement issued at the old (lower) policy rate that should have been higher under 2025 cost-basis policy.
每份支付报告都会包含以下五种模式中的一种或多种：
  1. 尺寸等级分类错误：商品被按更高的尺寸等级计费，但其实际尺寸并不符合该等级标准。需核对商品列出的尺寸与FBA等级表。
  2. 缺失推荐费返还：退款已处理，但推荐费未按比例返还。需核对退款记录与原始销售记录。
  3. 重复配送费：同一订单被收取两次FBA费用，通常是系统错误导致。
  4. 存储差异：已移除或在途的商品仍被收取月度存储费。
  5. 退款差额：按旧（较低）政策费率发放的退款，根据2025年成本基准政策本应按更高费率发放。

Step by step

操作步骤

  1. Collect inputs. A Payments report (date range, transactions) plus product dimensions for the SKUs in scope.
  2. Build the expected fees. For each SKU and order, what the fees should be by the current FBA fee tables.
  3. Compare row by row. Flag every transaction where actual exceeds expected, or where a refund did not produce a matching referral credit.
  4. Compute the recovery. Total dollars across all flagged transactions.
  5. Open the fee reimbursement case under Seller Support > Fulfillment by Amazon
    FBA Fee Discrepancies, one case per anomaly type, with the report rows as evidence and the calculated delta. (SAFE-T is a separate process for FBM/SFP A-to-z refunds, do not file fee disputes through it.)
  6. Plan the structural fix. A size-tier issue is recurring. The fix is updating the listed dimensions, not just claiming back.
  7. Run the quality check, then deliver.
  1. 收集输入信息：支付报告（日期范围、交易记录）以及相关SKU的产品尺寸。
  2. 计算预期费用：根据当前FBA费用表，计算每个SKU和订单的应缴费用。
  3. 逐行对比：标记所有实际费用高于预期费用的交易，或退款未产生对应推荐费返还的交易。
  4. 计算可追回金额：所有标记交易的总差额。
  5. 提交费用退款申诉：通过卖家支持 > Fulfillment by Amazon > FBA费用差异提交申诉，每种异常类型单独提交一个申诉，附上报告行作为证据及计算出的差额。（SAFE-T是处理FBM/SFP A-to-z退款的独立流程，请勿通过该渠道提交费用申诉。）
  6. 制定结构性修复方案：尺寸等级问题属于重复出现的问题，修复方案是更新商品列出的尺寸，而非仅追回费用。
  7. 进行质量检查，然后交付结果。

Worked example

示例

A seller's product is billed at large-standard but actually measures small-standard. 20 days of orders sit at the wrong tier, costing ~1.20 USD per unit. 800 units sold in period = 960 USD overcharge. An FBA fee-discrepancy case opens under Seller Support FBA Fee Discrepancies with the report rows, the correctly-measured dimensions, and the tier-table reference. Recovery typically within two weeks. Structural fix: update the dimensions in the listing so the issue does not recur. The seller had been paying the wrong fee for months.
某卖家的商品被按大型标准尺寸计费，但实际属于小型标准尺寸。20天内的订单均按错误等级计费，每件多收约1.20美元。该周期内共售出800件，总计多收960美元。需通过卖家支持的FBA费用差异渠道提交申诉，附上报告行、正确测量的尺寸以及等级表参考。通常两周内可追回款项。结构性修复方案：更新商品列表中的尺寸，避免问题再次发生。该卖家此前数月一直支付错误的费用。

Quality check

质量检查

  • Every anomaly is one of the five named types.
  • Expected fees are computed from the current FBA tables, not assumed.
  • Each finding has report rows as evidence, not just a calculation.
  • The structural fix is included so the leak does not recur after the recovery.
  • 所有异常均属于上述五种类型之一。
  • 预期费用根据当前FBA费用表计算，而非主观假设。
  • 每个问题都附有报告行作为证据，而非仅提供计算结果。
  • 包含结构性修复方案，避免追回款项后漏洞再次出现。

Common mistakes

常见错误

  • Auditing only when it feels expensive. Most fee leaks creep quietly.
  • Claiming the dollars without fixing the source. Same anomaly returns next month.
  • No expected-fee baseline. Without 'what should it have been', there is nothing to detect.
  • Ignoring referral refunds. Easy to miss on high-refund SKUs and small per-item.
  • 仅在费用过高时才审核：大多数费用漏洞是悄然出现的。
  • 仅追回款项而不修复根源：相同异常下月会再次出现。
  • 无预期费用基准：没有“应缴费用”作为参照，就无法检测异常。
  • 忽略推荐费返还：高退款率SKU和小额单品的推荐费返还容易被遗漏。
