Get paid in USDT/USDC without creating a tax-season disaster. Audit-proof crypto invoice template (with TX hash + block timestamp fields), a multi-wallet income tracker with cost-basis columns, a 10-minute quarterly tax summary routine, a wallet-address verification checklist with the test-transfer protocol, five late-payment email templates written for crypto failure modes, and a full guide: how crypto income is taxed, the five failures that break audits, and how to convert to fiat cleanly. Built for freelance developers, designers, and DAO contributors. Templates and record-keeping guidance — not tax advice.
