Mark invoice as paid manually

Mark Invoice 1983 for client Oak & Row as paid. Payment was received via bank transfer for $3,400 on July 12. Update payment status, record the payment date and method, and add a note: "Received 12 Jul, ref TRX9876." Then email a receipt to the contact Lydia Hart and cc our records inbox.

Before I mark invoices as paid, make the action audit-safe: surface the bank reference and payment date up front, verify the amount matches an open invoice, and flag if the payment lacks a matching reference or is a partial payment so I don’t misapply funds.

I received a bank transfer from Oak & Row that nearly matches Invoice 1983 but is $50 short. I don’t know if it’s a partial payment, a bank fee, or a mistaken amount. I’m worried marking it paid will misreport revenue. What should I check now and what note or communication should I send to the client before I finalize the status?

We keep marking invoices as paid on sight of transfers and later discover mismatches, which creates reconciliation headaches. Is the root cause poor payment instructions, lax checking, or pressure to clear accounts quickly? Recommend one strict verification step to add to our workflow that prevents misapplied payments without adding lots of extra work.
