🔒 100% local. Your reports never leave your machine.

Reconcile the Amazon deposit.
Explain profit by SKU.
Export a cleaner journal.

SkuSum runs locally in your browser. It joins Orders, Settlement, Ads and COGS exports into one reviewable file for Amazon sellers and bookkeepers.

No sign-up required. Your reports never leave your machine. The Chrome extension is the same tool, bundled to run with no connection at all. Or see a sample reconciliation first.

Your numbers live in reports that don't even agree with each other

The summary report says one thing, the transaction report another. A SKU looks profitable until you add ads, returns, storage and FBA fees. And ads you paid by credit card never show up in settlement at all. The math is manual, and your spreadsheet breaks every month.

How it works

Three steps, all on your machine.

1

Export your reports

Grab the reports you already download from Seller Central: Orders, Settlement and Ads, plus your own cost file.

2

Drop and join, locally

Drag them in. SkuSum stitches them on SKU and date into one clean dataset, right in your browser, and flags any rows that don't reconcile.

3

Export what you own

A clean profit-by-SKU sheet (CSV or Excel) that's yours to keep, plus a balanced QuickBooks / Xero journal per settlement, co-designed with practicing bookkeepers.

Numbers you can actually trust

Most tools hand you a profit number and ask you to trust it. With SkuSum, you can check every one. The parser is validated against 161,344 real settlement lines from US, UK, German and Indian seller files, with every line classified.

✅ Reconciled, not estimated

Net proceeds are the sum of your real settlement per SKU, after Amazon's actual fees, not a model's guess.

⚠️ Flags what doesn't match

Rows where Orders and Settlement don't line up are marked, so a clean-looking sheet never hides a silent gap.

🔎 Verify it yourself

You keep the joined file and the raw inputs. Every number traces back to a report you can open and check.

SkuSum status strip: books tie out with debits equal to credits, one SKU flagged for margin review, above the KPI row and settlement breakdown
Your books can tie out while SKU profit still needs review. SkuSum shows both, and flags the exact line to check.

Why not just use what exists?

Because nobody hands you clean, joined data that's yours, and that you can verify.

Privacy isn't a feature here. It's the architecture.

Built so your data has nowhere to leak.

🔒 Local-only

Joining and cleaning happen in your browser. No server upload.

🙈 No buyer data

We only touch SKU, fees, ads and dates, never buyer names or addresses.

🔑 No credentials

You export your own reports. We never see or store your Amazon login.

📤 You keep it

Export and walk away. No account to close, and nothing of yours on our side to delete.

FAQ

Can I trust the numbers?

SkuSum sums your actual settlement per SKU (not an estimate) and flags any rows where Orders and Settlement don't match. You keep the raw inputs, so every number traces back to a report you can open and check yourself. The parser is validated against 161,344 real settlement lines from US, UK, German and Indian seller files, every line classified, and anything it cannot classify in your file is flagged for review instead of guessed. The full list of line types and where each one belongs is on the fee types glossary.

Is my data safe? Where do my reports go?

They stay on your machine. SkuSum runs inside your own browser, so your reports are never uploaded and nothing reaches our servers. We don't even read buyer personal data.

Does AI touch my numbers?

No. There is no AI in the product: no model, no LLM, no call to any AI service. SkuSum is a deterministic parser. It applies fixed mapping rules, does arithmetic, and the same file always produces the same journal. Every number traces back to a settlement line you can open and check, and anything the rules cannot classify is flagged for your review instead of guessed. A bookkeeper cannot trust a number a model guessed, so we kept models out on purpose.

Why not just do this with ChatGPT or Claude?

I use AI models every day and my own operation runs on them, so this is not an anti-AI position. It is about what a model can promise. Ask one to classify the same settlement file twice and you can get two different answers, and on a fee code it has not seen before it will help you by guessing instead of stopping. The journal balances either way, which is exactly why a reviewer will not catch it. Books need the opposite property: same input, same output, every line traceable, and a hard stop on anything unrecognized. That is a parser's job, not a model's.

How is this different from Sellerboard or A2X?

Dashboards keep your data in their cloud and ask you to trust their number. Accounting connectors like A2X summarize the detail away and charge more as you grow. SkuSum gives you the clean, joined, SKU-level file itself, reconciled to your own reports and yours to verify, analyze, or hand to your bookkeeper.

Why not just use Amazon's built-in SKU Economics report?

The SKU Economics report is a solid operating view, and for watching a SKU over the long run it is often enough. But it is built for the dashboard, not your books. It doesn't tie back to the settlement payout that actually reached your bank, and it gives you no journal to import into QuickBooks or Xero. SkuSum starts from the settlement, so every number reconciles to the money that arrived, categorizes each fee, refund and reimbursement, and hands you a balanced journal your bookkeeper can review and import. It also flags the rows that don't reconcile instead of averaging over them. Use the SKU Economics report to watch a SKU over time. Use SkuSum when the number has to match your bank and your books.

Will it work with QuickBooks or Xero?

Yes. SkuSum exports a balanced QuickBooks / Xero journal per settlement (sales, referral and FBA fees, withheld tax, refunds folded into their home accounts, and COGS as proper entries), reviewed with bookkeepers who run Amazon clients, plus a clean profit-by-SKU sheet (CSV or Excel). It is a one-way, import-ready journal file, not a live API sync (by design: nothing connects to your accounts, nothing to break when Amazon changes). See the account mapping, or join below to help shape what comes next.

How much will it cost?

The core tool is free during validation. Paid licenses: SkuSum Founding Pro, $49 one-time (lifetime Pro, limited to 10 founding seats) and SkuSum Bookkeeper Founding, $199 per year (adds rights for paid client work). Full details on the pricing page. Prices are in USD; taxes may apply and will be calculated at checkout. No per-order pricing: flat, ever.

Does it get around Amazon's report limits?

Amazon only keeps about 90 days of settlement data. SkuSum doesn't store anything for you, but every run gives you a dated file to save. Export regularly and your own saved files become the long history Amazon won't keep. (An optional on-device history is on the roadmap.)
