How do I log a payment I took in cash or by check?

Manual payments sit alongside synced ones and count everywhere — revenue, margin, tax. Use it for cash, checks and anything that came through a processor you have not connected. The form has an optional Check / reference # field: type the check number or the transfer reference when you have it. It is never required, and it does one job — when your accounting system or your bank later delivers its own copy of that same payment, DeskOps recognises it as the same one, and a different check for the same amount from the same customer stays a second payment instead of being folded into the first.
