Most invoicing advice assumes PayPal or Stripe just works. They don't for everyone — both routinely refuse to pay out to certain countries, freeze accounts without much explanation, and take a cut on top. Crypto is a practical fallback: no processor account to get approved for, near-zero fees, and it settles in seconds instead of days.
USDT (Tether) is a stablecoin pegged to the US dollar, so you're not exposed to price swings the way you would be holding raw Bitcoin. TRC20 is USDT issued on the Tron network — transaction fees are usually a few cents, versus several dollars on Ethereum (ERC20). For a freelance invoice, that difference matters. See the live fee comparison for current numbers.
You don't need a hosted payment processor to know if you got paid — TRC20 transfers are on a public ledger. crypto-pay-cli is a free, open-source command-line tool that checks incoming USDT transfers to your address and generates a receive QR code, using the public TronGrid API directly. No account, no API key.
