A Solana Pay link and QR with a unique reference key. Phantom, Solflare or a copied address all work.

USDC lands, receipt writes itself
PayLink watches the chain for the reference, checks the amount and mint, then issues the receipt.
The books
Every invoice, reconciled against the chain.
Status changes only when a matching USDC transfer confirms. No screenshots of bank apps, no “sent it, check now”.
