An instrument number is one of the few things in a recording office that can never be taken back. Once a number is issued, it belongs to that document for good. A gap in the sequence is a question someone will have to answer for years.
So RecordOne is careful about when a number is issued.
Drafts do not use numbers
A clerk can start an order, add items, save it as a draft, release it to the queue for a colleague, and come back to it later. None of that issues a document number. The order has its own order number for reference, and that is all.
Finalizing does three things at once
When the clerk chooses Finalize Order, RecordOne posts the payment to the drawer, assigns the document numbers and sends each document to the Scan queue. These happen together or not at all. If finalizing fails for any reason, no numbers are used up.
A dropped connection is not a double charge
Networks fail at bad moments. If the screen reports that confirmation was interrupted, the clerk chooses Retry finalization, and RecordOne recovers the same receipt. The payment is not collected twice and the document does not receive a second number.
Why it matters
None of this shows on a feature list. It shows up later, when someone asks what happened to a number and the office has a clear answer.
