Case Study: How SellAnalytix Helped a Six-Figure Amazon Brand Gain Financial Clarity

Background

John, an experienced Amazon seller, had built a successful six-figure business using a combination of retail arbitrage and private label products. His revenue had grown steadily, but his financial management system hadn’t evolved alongside his business.

  • Sales Channels: 85% Amazon FBA & 15% FBM
  • Business Model: Mix of retail arbitrage (purchasing discounted products in-store) and private label (manufacturing and branding his own products).
  • Revenue: $220,000 per year
  • Accounting Method: Cash-based tracking with messy paper receipts and spreadsheets
  • Tools Used: Google Sheets, Amazon Seller Central reports, bank statements

The Problem: A Disorganized Accounting System

John’s financial workflow was time-consuming and error-prone. He relied on manual data entry to track purchases and profits, which created major issues:

  1. Messy Receipts from Retail Arbitrage

    • Manually storing and scanning physical receipts made it difficult to categorize and track expenses accurately.
    • Lost receipts meant missing deductions and incorrect financial reports.
    • He got behind on inputting accurate COGS leading to him being always behind.
  2. Delayed Inventory and Profitability Insights

    • Since he used spreadsheets, his inventory and profit tracking were always weeks behind.
    • He couldn’t easily see real-time SKU profitability or cash flow trends.
  3. End-of-Year Tax Chaos

    • Without an automated accounting system, tax season was a nightmare.
    • He spent weeks organizing expenses, matching receipts, and estimating COGS for his tax filings.
  4. No Live Data for Decision Making

    • His method only showed past performance, making it hard to plan future purchases or see real-time business health.

The Workflow Before SellAnalytix

  1. Purchase Tracking: Manually recorded each retail arbitrage purchase in Google Sheets.
  2. Sales & Revenue: Downloaded Amazon reports monthly and entered figures manually.
  3. Profit Calculation: Used a mix of spreadsheets and bank statements, often with discrepancies.
  4. Taxes & Reporting: Waited until the end of the year to categorize expenses, leading to unexpected tax bills.
