The job is finished. You send a message: 40,000 left. The client replies that they already paid everything except the finish, and that the cabinet was not in the quote. Both of you are searching WhatsApp between photos of tile. The final bill does not need a meeting if the page shows where the number comes from.
The final number is a subtraction, not a surprise. Quote that was approved, minus what was paid at each stage, plus extras that were written before they started. If one of those is missing, the client cannot check, and they wait.
What sits on the page
- The approved quote amount, with the date
- Every payment already received, with date and amount
- Every extra approved in writing, with the amount
- What came off the quote, if you removed work to bring the price down
- The balance, and when it is due
An example of the shape, not a price list: quote 180,000. Paid at the start 50,000, after demolition 40,000, after tiling 40,000. Extra: moving a water point, 3,500, approved before it started. Removed: rubble the client took on, 2,000. Balance 51,500. The client sees the bill without asking where it came from.
What does not appear at the last minute
Work that was not written before it started does not show up as a surprise on the final bill. If you forgot to write an extra, say so now on a separate line, with what was done and why it was not in the quote. Do not hide it inside the balance. A round balance with no lines is where the client stops the transfer.
Tax is written the same way as in the quote. If the quote was before tax, the balance is before tax too, and the tax line stands alone. A mix-up here is almost a fifth of the bill, and it shows up exactly when the money is supposed to arrive.
Send it with what closes the questions
Attach the quote, the extra approvals, and the defect list that was closed. Not twenty files with no names. Three, with a clear name. In the message: final bill attached. Balance 51,500 according to the page. Waiting for the transfer by Thursday.
If the client disputes a line, answer that line, not the whole bill. What is agreed can be asked for now. What is open stays out until there is an answer. Do not hold an entire balance because of an argument about a small amount, and do not drop the line just to close the transfer.
When the page is clear, the conversation is short. When the page is a number, the conversation is the whole history of the job.
