Small tools for Amazon sellers.
Free. No account, no email, no trial. Each one does a single thing and does it on your own machine.
🔒 Nothing you open here is uploaded anywhere. Every tool parses your file in the browser — there is no server, no database, no analytics call touching your data. Disconnect from the internet and they still work.

Amazon Settlement Report Parser
Drop a Flat File V2 settlement report and see how the payout was actually built — fee breakdown, reserve amounts, postings that fall outside the settlement period, per-SKU net.
Also includes a field and fee-code reference that Amazon does not publish, and the six things Amazon leaves undocumented.
More tools are added as sellers tell me what they're fighting with. If there's a report you keep pulling apart by hand in Excel, tell me which one.
I build data pipelines and reconciliation tooling. Before that I spent several years in cross-border e-commerce and a few more in manufacturing, which is where I learned how much of this job is really just reconciling one export against another at two in the morning.
These tools run entirely in your browser on purpose. A settlement report is your financial data — you shouldn't have to hand it to a stranger to find out why the numbers don't add up.
If you run several accounts and need them archived and merged automatically every month — Amazon only keeps about 90 days, then they're gone — that's the paid version of this — support@nexusaistart.com
