Most tools for tracking resale either chase the listing (crosslisting apps) or chase the invoice (accounting software). Neither was built around the thing a reseller actually owns: an item with a receipt, a sale, and a tax year.
Making Tax Digital for Income Tax starts in April 2026, with the mandatory threshold dropping every year after. Platforms already report seller data to HMRC. The spreadsheet-and-shoebox approach that used to be good enough now leaves a real gap between what's reported and what a reseller can prove.
MyCops exists to close that gap — one place where every number traces back to the document that proves it.
