Common Recordkeeping Mistakes in FBA Audits

Mar 27, 2025

Keeping accurate records is critical for Amazon FBA sellers. Poor recordkeeping can lead to lost reimbursements, audit headaches, and compliance issues. Here’s what you need to know upfront:

Key Mistakes to Avoid:

  • Inaccurate Inventory Tracking: Missing shipment details or relying only on Amazon’s reports can hurt your claims.

  • Misclassified Costs and Income: Mixing up fees, refunds, or taxes complicates audits.

  • Missing Reimbursement Records: Without proper documentation, you risk losing refunds.

  • Short Record Storage: Keeping records for less than 18–24 months limits your ability to resolve disputes.

Quick Solutions:

  • Use digital tools to track inventory and finances.

  • Separate and organize expenses (e.g., storage fees, shipping costs).

  • Automate reimbursement tracking with tools like Refunzo.

  • Store records securely for at least 24 months with cloud backups.

Pro Tip: Automating recordkeeping with tools like Refunzo can save time, reduce errors, and recover lost refunds efficiently.

Keep reading for a detailed breakdown of common mistakes, solutions, and how automation can simplify FBA audits.

Top Recordkeeping Errors in FBA Audits

Poor Inventory Tracking

Keeping track of inventory accurately is a common problem for FBA sellers. Issues like not recording initial shipment quantities, ignoring damaged inventory upon arrival, or missing discrepancies between shipped and received units can cause major headaches during audits. Without this information, verifying inventory losses or damages becomes nearly impossible.

One big mistake is depending entirely on Amazon's inventory reports without keeping your own records. If discrepancies show up, sellers often lack the proof needed to back their claims. For example, if items are labeled as 'disposed of' or 'damaged' in Amazon's system, having independent records can confirm these statuses.

On top of this, mistakes in financial record classifications can add even more confusion during audits.

Wrong Cost and Income Categories

Misclassifying expenses and income can make audits unnecessarily complicated. Here are some common errors and their consequences:

Common Mistakes

Impact on Audit

Storage Fees

Mixing long-term and standard storage fees

Skewed profit calculations

Refund Costs

Combining customer refunds with FBA reimbursements

Double-counting losses

Shipping Expenses

Combining inbound and customer shipping costs

Misleading cost analysis

Sales Tax

Failing to track marketplace tax collections separately

Issues with tax compliance

Missing Reimbursement Records

Lack of proper documentation for reimbursement claims can significantly hurt audit results. Sellers often fail to:

  • Track the status of reimbursement requests

  • Record the reasons for claims

  • Keep proof of the original shipment's condition

  • Log Amazon's responses to claims

Without this information, it becomes tough to know which claims were approved, denied, or still pending. This can lead to unclaimed reimbursements worth thousands of dollars.

Short Record Storage Time

Many sellers don’t keep records long enough. While Amazon allows an 18-month window for most investigations, many sellers only save records for 6–12 months. This short timeframe creates problems in areas like:

  • Reconciling old inventory

  • Verifying long-term storage fees

  • Analyzing performance over multiple years

  • Providing compliance documentation

On top of that, poor digital storage practices can lead to permanent data loss. Without detailed historical records, sellers face serious challenges during audits or when disputing fees and charges.

Solutions for Better Recordkeeping

Better Inventory Management

Keeping accurate inventory records requires a structured approach. Start by using a digital tracking system to log shipment quantities, conditions, and tracking numbers. Take photos of inventory before shipping to document its condition. Perform weekly audits by comparing your records with Amazon's reports, and log any discrepancies in a spreadsheet or tracking tool.

Once your inventory records are in shape, ensure your financial records are just as organized.

Correct Money Tracking

Organizing your financial records is key to smooth audits. Here's a simple way to structure your tracking:

Category

What to Track

Documentation Needed

Storage Fees

Standard vs. Long-term

Monthly fee statements, inventory age reports

Shipping Costs

Inbound vs. Customer

Carrier invoices, Amazon shipping reports

Refunds

Customer vs. FBA

Case IDs, resolution details, payment confirmations

Sales Tax

By marketplace

Tax collection reports, remittance records

Keep separate digital folders for each expense category. Use a master spreadsheet to link all transactions for easy reference.

Once this is set up, you can shift your focus to managing reimbursement claims effectively.

Reimbursement Claim Tracking

Develop a system to track reimbursement claims thoroughly. For each case, document key details like case numbers, submission dates, and claim types. Automated tools can help here - Refunzo, for instance, runs over 20 checks to identify discrepancies that may qualify for claims.

"Been using them for a while - efficient service, reasonable price and seem to constantly be finding money that Amazon owes me." - Danny

Monitor the progress of each claim. Record the amounts and dates of successful reimbursements. For denied claims, keep Amazon's responses and any additional evidence for future follow-ups.

Record Storage Guidelines

Set up a storage system that goes beyond Amazon's 18-month requirement. Aim to keep records for at least 24 months to cover any delayed disputes or investigations. Use cloud storage with automatic backups to protect against data loss.

Organize your files like this:

  • Inventory records by quarter

  • Financial documents by fiscal year

  • Reimbursement claims by case type

  • Shipping documentation by carrier

Back up all records in at least two places - one of them cloud-based for easy access. Update your storage system monthly to keep everything current and easy to retrieve.

Using Refunzo for FBA Records

Refunzo

Refunzo simplifies tracking and managing your FBA records by automating checks and spotting discrepancies in your account.

Refunzo's Auto-Check System

Refunzo uses a 21-point automated check system to keep your records in order. It reviews your Amazon account across multiple areas:

Check Category

What Gets Verified

Shipments

Stock deductions, damaged items, missing units

Inventory

Lost items, warehouse transfers, returns

Payments

Fee calculations, overcharges

Refunds

Customer returns, FBA errors

By connecting directly to your Amazon Seller Central account, the system scans transactions and flags issues that might affect audits. These automated checks not only make recordkeeping easier but also help identify refund opportunities, as explained below.

Finding Missing Refunds

Refunzo's automated reports help uncover refund opportunities by addressing common errors:

  • Identifies lost or damaged inventory that manual reviews might miss

  • Flags misallocated stock during warehouse transfers

  • Spots incorrect fee charges

  • Highlights processing mistakes in customer returns

"I mainly use Refunzo for finding inventory that was lost or damaged at Amazon's warehouse and they are worth every penny of the commission they charge. I will continue using them for a long time." - Robert Cuttler

Getting Help with Claims

Refunzo goes beyond identifying issues by offering full support for reimbursement claims. Their team:

  • Creates and submits support cases to Amazon

  • Prepares all necessary documentation to back up claims

  • Follows up until refunds are processed

  • Ensures recovered funds are deposited directly into your bank account

The service charges a 15% success fee on recovered amounts, capped at $5,000, and only applies after funds are reimbursed.

"We have been using Refunzo for about 4 years and we have been very pleased with their service. They are extremely easy to work with and charge less than most refunds services around while getting more back in refunds than our last service." - David Cummings

For audits, Refunzo keeps detailed records of all claims and resolutions, ensuring a clear paper trail that meets Amazon's compliance requirements. Each case is handled individually, providing documentation that supports your audit needs while recovering lost funds.
