# Match a Pennylane supplier invoice to a bank transaction

Links one Pennylane supplier invoice to a bank transaction that already happened on the company's account, which marks the invoice as paid in the books. It never sends a payment. With dryRun (default true) it only reads the invoice and the transaction and returns both, without linking them; dryRun false links them and returns the amount left to match (0 when the amounts agree, a small value for a currency gap, the difference when the transaction is larger than the invoice). Find the transaction with app.pennylane.com/find_transactions_for_invoice. Fails when the invoice or the transaction does not exist, and when signed out of Pennylane.
