The Client
A US-based health and wellness brand selling through Amazon FBA and Shopify, generating $3.2 million in annual revenue across approximately 45 SKUs. The founder had been running the business for three years with an in-house bookkeeper using QuickBooks Online.
The Problem
The founder believed the business was running at a 42% gross margin — healthy by any standard. Pricing, inventory orders, and growth investments were all based on this number.
The problem: it was wrong. The bookkeeper was only capturing purchase price as COGS. Four entire cost categories had never been included in the margin calculation.
Key insight: In e-commerce, purchase price is only one component of COGS. Inbound freight, customs duties, FBA fees, storage costs, and returns all belong in the cost structure — and all directly affect margin.
What We Found
Wealthovation's team conducted a full COGS reconstruction across all 45 SKUs. Here's what the original books were missing:
| Cost Category | Annual Amount | Status Before |
|---|---|---|
| Purchase Price | $1,856,000 | ✓ In COGS |
| Inbound Freight (Ocean + Last Mile) | $198,400 | ✗ Expensed as "Shipping" |
| Customs Duties & Brokerage | $86,500 | ✗ Buried in "Other Expenses" |
| Amazon FBA Fees (Pick, Pack, Referral) | $412,800 | ✗ Lumped into "Selling Expenses" |
| Returns & Damaged Inventory | $41,600 | ✗ Not tracked |
Total COGS after reconstruction: $2,595,300 — versus the originally reported $1,856,000.
Real gross margin: 18.9%, not 42%.
The Impact
The 23-percentage-point gap represented $274,000 in misunderstood profit. The founder had been:
• Setting prices based on inflated margins — leaving money on the table on some SKUs, losing money on others
• Over-ordering inventory for low-margin products
• Planning growth investments the business couldn't actually fund
What We Did
1. Full COGS mapping — every cost classified per IRS guidelines (IRC §471, §263A)
2. Per-SKU margin analysis — real profitability for each of the 45 products
3. QuickBooks restructure — new chart of accounts with proper cost categorization
4. Monthly reporting framework — automated COGS allocation going forward
5. Pricing recommendations — based on real margins, not fantasy numbers
Result: Within 60 days, the founder had discontinued 6 unprofitable SKUs, repriced 12 others, and shifted inventory budget toward 8 high-margin products. Projected annual margin improvement: $274K.
Key Takeaway
If your bookkeeper only puts purchase price in COGS, your margin number is fiction. For Amazon FBA and Shopify sellers, the real cost of goods includes freight, duties, marketplace fees, storage, and returns. Getting this wrong doesn't just affect your P&L — it affects every decision you make about pricing, inventory, and growth.
