About Sumkind

Sumkind is a pocket-sized companion for people who resell online. It brings your sales from Vinted, Depop, eBay and other marketplaces into one organised place, so you can see what you earned, what it cost, and what your profit actually looks like without spreadsheets or guesswork.

It is built for UK-based resellers and casual sellers who want to stay on top of their numbers and understand where they stand relative to the HMRC £1,000 trading allowance. Whether you sell a few items a month or run a busy side business, Sumkind turns scattered order confirmations and receipts into clear records you can trust.

Sumkind helps you track sales and expenses, estimate profit by platform, brand and category, and keep tax-relevant information visible at a glance. You can import history from a CSV, connect a mailbox for automatic tracking, or add sales by hand. Everything you record stays yours: you can edit or delete it at any time, and nothing is shared with third parties for advertising.

Sumkind is made by a small, independent team that believes record-keeping should be simple, private and honest. The app organises the information you provide but does not give tax advice or determine your tax status — it simply helps you see the picture, so you can make confident decisions and share clean records with an accountant or HMRC when the time comes.
