The small payment memo with a big accounting job
Reconciliation is part of a payment product, not an optional afterthought.

The mechanism
A payment needs to be associated with the correct obligation. Solana’s payment documentation includes optional memos as a way to attach reconciliation context. An on-chain transfer and a merchant’s invoice system remain different records that must be matched carefully.
Put it into practice
For an illustrative invoice, assign a random reference instead of publishing a customer’s name, email or private order details. Store the sensitive information in the business system and map the reference there. Confirm the token, amount, recipient and transaction outcome before marking an invoice paid. A memo helps identify intent; it does not independently prove that the expected transfer succeeded or that the sender owns the underlying customer account.
Keep the evidence in view.
