SkuSum turns the four Amazon reports that never agree (Orders, Settlement, Advertising and your own COGS file) into one answer: which SKUs actually make money, and a balanced QuickBooks or Xero journal that ties to the deposit to the cent. Everything runs locally in your browser. Nothing is...

As answered by people managing SkuSum and https://open-gpt.app/.
SkuSum's answer
It runs entirely in your browser. Your Amazon reports are never uploaded, there is no account, and there is no Amazon login or API access, so it cannot break when Amazon changes its API. It is also deterministic, with no AI touching your numbers, and it refuses to guess: unknown fee types are flagged for review instead of silently miscategorized.
SkuSum's answer
Most tools either sync through your Amazon account or price per order, so the bill grows as you grow. SkuSum is local-first and flat-priced. It ties every settlement to the deposit to the cent, explains profit per SKU, and builds a balanced QuickBooks or Xero journal you can actually audit line by line.
SkuSum's answer
Amazon sellers who want true profit per SKU, and the bookkeepers and accountants who close their books. Bookkeepers get per-client workspaces so each client keeps its own chart-of-accounts names and fee mappings.
