# Tracking payments \[When invoices get marked paid, and attaching transactions]

An invoice is marked paid automatically when the payer completes payment through the invoice page (by [connecting a wallet or submitting a transaction link](/invoicing/paying)) and Splits verifies the transaction onchain. Verification requires a single transaction covering the full amount: overpayment is accepted, underpayment is rejected, and there are no partial payments. The verified transaction is attached to the invoice automatically.

For payments that arrive any other way (including bank transfers), mark the invoice paid from the *Invoices* page. You can attach one or more transactions for bookkeeping; manually attached transactions are not amount-checked. Reverting an invoice from paid detaches its transactions.
