Selling on platforms like Amazon, Walmart, and Temu offers tremendous opportunities — but the billing systems behind these marketplaces are notoriously complex. Many sellers unknowingly overpay thousands of dollars in hidden fees every year.
The solution? A robust billing reconciliation strategy designed to identify, validate, and recover every cent you’re owed.
Understanding Marketplace Billing Systems
Each eCommerce platform has its own billing structure:
Amazon charges sellers for referral fees, FBA (Fulfillment by Amazon) storage and fulfillment, advertising costs, and refund adjustments.
Walmart includes commissions, WFS (Walmart Fulfillment Services) storage costs, and ad spend fees.
Temu bills sellers based on performance-based fees and marketplace deductions.
Because these systems are automated and multifaceted, small discrepancies can easily go unnoticed — making FBA account reconciliation an essential process for every serious seller.
Hidden Fees That Hurt Your Profits
Even experienced sellers miss recurring charges that gradually chip away at margins. Common examples include:
Ad spend discrepancies – campaigns charged outside their intended budgets.
Storage overages – unexpected FBA or WFS costs from excess inventory.
Incorrect referral fees – miscategorized products leading to inflated commissions.
Uncredited returns – missing reimbursements for damaged or returned products.
Over time, these small errors can add up to major profit losses — which proper FBA reconciliation can help prevent.
Building an Effective Reconciliation Routine
Here’s a step-by-step process to build a billing reconciliation workflow that protects your margins:
Pull detailed reports from Amazon, Walmart, and Temu dashboards.
Organize charges by category (ads, storage, fulfillment, returns, etc.).
Cross-check each charge with your internal sales and inventory data.
Flag discrepancies and submit reimbursement requests promptly.
Document everything for future audits and recurring reviews.
Businesses that maintain consistent FBA account reconciliation routines often recover thousands in overpaid fees every year.
Proven Success Stories
A home goods seller discovered duplicate Amazon FBA storage charges — recovering $8,200 in overbilled fees.
A Walmart marketplace merchant corrected referral fee categories and reclaimed $2,500.
A Temu seller identified ad billing mismatches and received $1,100 in credits.
These examples show the real-world value of disciplined FBA reconciliation and detailed billing audits.
