No money moves. This writes down a payment that already happened.
Nat is emailed that it is booked, and it comes up on his list with Pass and Fail.
The surcharge is a separate line on the receipt and is NOT part of the contract price, so it is recorded beside the draw and never added to it.
Only the dates on file change. Nothing is sent.
Read it, edit it if you want, then Send. It goes to the client from info@, copied to info@, and marks the draw billed. Nothing leaves until you press Send.
