The customer said yes on the phone. You did the work, they were happy, and then the next job started. The invoice moved to tomorrow, then to the weekend.
“Whenever there is time” usually means late, and an invoice that is not sent is an invoice that is not paid. Nobody decides to do this. It happens when you are busy.

What waiting costs you
A sale that is not billed within a day or two is money you are waiting on for no reason. It rarely feels like a problem, because the work is done and the customer is happy. It just shows up as cash that arrives later than it should, or not at all.
Why invoices go out late
It is almost never carelessness. Three ordinary things cause it: the approval was verbal, so nothing marks the job as ready to bill; retyping a quote into an invoice is tedious; and the invoice sits as a draft because you meant to check it later. A fixed routine removes all three.
The process: four steps from approved to sent
1. Record the approval the day it happens
When the customer says yes, note it that day so the job is visibly ready to bill.
Example: “Confirmed Tuesday by phone, bill on completion.”
Pro tip: Write the billing date next to the approval before you start the work.
2. Build the invoice from the approved quote
Copy the lines, quantities and prices from the quote so nothing is retyped and nothing is dropped.
Example: “Same five lines as the quote, plus the extra hour agreed on site.”
Pro tip: Add any change agreed on site before you send, not after.

3. Finalize it the same day
A draft invoice does not count toward your real revenue picture. Check it, then finalize it so it becomes a real record.
Example: “Totals and tax checked, finalized before leaving the site.”
Pro tip: Pick one day a week to look for drafts left behind.
4. Send it straight away
The customer should receive it the moment it is final, not whenever you remember.
Example: “Hi Sam, your invoice for Tuesday’s job is attached. Payment details are at the bottom.”
Pro tip: Automatic sending removes the step you are most likely to forget.
Where this runs
All four steps work on paper or a spreadsheet. When invoices pile up, we run the same routine inside the business system we set up for clients (Odoo Community): confirm the sales order, create the invoice from it so the lines come across, validate it, and turn on automatic invoice emailing. After a week you can see what has been billed and what is still only a quote. The process is the point. The tool just keeps it going when you are busy.
