Case Study: How SellAnalytix Helped an 8-Figure Amazon Brand Automate Accounting for 32,000 SKUs
Background: Scaling Challenges for a High-Volume Amazon Business
Sarah and her team run an $18M per year Amazon business, selling 32,000 SKUs across multiple product categories operating a wholesale model. With 98% of sales fulfilled via Amazon FBA, they owned & operated a large warehouse for restocking inventory and handling direct shipments from suppliers.
As the business scaled, accounting inefficiencies became a major bottleneck. Managing financials for such a high-volume business required daily reconciliations, automated bill processing, and seamless coordination between the warehouse, accounting team, and bank accounts.
- Sales Channels: Amazon FBA (98%), Limited FBM (2%)
- Business Model: High-SKU catalog with 3,000+ daily sales.
- Warehouse Operations: Large-scale storage & supplier shipments
- Accounting Complexity: Multiple bank accounts, 10+ employees on payroll, high transaction volume, multi-user team
- Previous Accounting Method: A mix of QuickBooks, spreadsheets, and manual uploads
The Problem: Inefficient, Labor-Intensive Accounting Processes
With tens of thousands of transactions per month, Sarah’s team faced several major issues that slowed down operations and created financial blind spots:
Manual Bill Uploads & Delayed Expense Tracking
- Their warehouse received daily shipments from suppliers, but bills were processed weekly or even bi-weekly.
- This led to delayed cost tracking, causing discrepancies in cash flow analysis.
Disorganized SKU-Level Profitability Tracking
- With 32,000 active SKUs, profitability tracking was inaccurate and delayed.
- Spreadsheets couldn’t keep up with real-time FBA fees, Amazon storage costs, and supplier invoices.
Slow Bank Reconciliations Due to High Transaction Volume
- The company processed hundreds of transactions per day across multiple bank accounts.
- Weekly reconciliations required hours of manual work, leading to delays in financial reporting.
Lack of Integration Between Warehouse, Accounting, and Amazon Data
- The warehouse team manually logged inventory receipts and shipments, which had to be manually entered into accounting software.
- This caused inconsistencies between what was in Amazon’s system and the company’s internal records.
The Workflow Before SellAnalytix
- Receiving Bills → Warehouse staff received shipments and sent invoices to accounting.
- Data Entry → Team manually entered supplier invoices into QuickBooks.
- Revenue Reporting → Amazon sales data was pulled weekly, meaning financial reports were always outdated.
- Bank Reconciliations → Accounting team manually matched transactions across multiple accounts.
- Profitability Analysis → SKU margins were manually analyzed in spreadsheets, leading to errors and delayed insights.
