Why it can work

  • Joining settlement rows and ad spend by hand takes hours.
  • Lumped payouts hide net profit for each product each month.
  • Sellers cannot see when sales started dipping by product.

Watch out

  • Thin margins after fees may leave little to track.
  • Sellers may not link supplier invoices to account data.

The job to be done

Calculate true per-ASIN Amazon profit

When Amazon payouts lump fees and ad spend together and sales trends are hard to see, small sellers need per-ASIN profit tracking so they can see which products actually make money.

Cannot see monthly or weekly sales by ASIN over time to spot when sales started dipping.

Joining settlement report rows, fees, and ad spend by hand takes hours to get true per-ASIN profit.
r/AmazonSeller5 upvotes
New seller saw ROAS collapse after raising ad budget, and referral plus FBA fees leave almost no margin so they lose money monthly.

Amazon fees and expenses are lumped into one payout, so the seller cannot see net profit per SKU each month.
r/AmazonSeller2 upvotes
Seller wants to compare supplier invoices against Amazon account data to check units, profit and fees.
