About ResalePocket
Last updated 2026-10-28
ResalePocket is a set of browser tools for people who sell second-hand things online. It answers three questions: what a marketplace keeps from a sale, what you keep and what price you need, and whether a platform reports your sales to a tax office.
How it works
- Rules come from the official page. Every fee and threshold is read from the marketplace’s own fee page or the tax authority’s own page. Each calculator lists those pages with the edition they show and the date we checked them, and the changelog records every change.
- One engine, tested. All calculators use the same rules engine, written as a plain JavaScript module with tests built from the worked examples on the official pages. The same engine is meant to run inside the ResalePocket apps later.
- Your numbers stay with you. Everything is worked out in your browser. The ledger and the spreadsheet keep their data in your browser only.
- No account connection. The tools do not log in to any marketplace, do not act on your account and do not read it. You type numbers in or import a file.
- Not advice. Reporting thresholds and tax lines are explained next to each other because they are different numbers. The pages organise your numbers; they are not tax or legal advice and not a filing document.
If a rate is out of date or a result looks wrong, tell us through the contact page.
Who runs it
ResalePocket is owned and operated by SKYSEED TECH LLC. You can write to us at support@resalepocket.com or through the contact form.
Plans
The calculators are free. A Pro ledger with unlimited items, yearly reports and imports is planned but not on sale; see Pro. The site shows no advertising.
