Part two

How that document was put together

Nothing was written up at the end. Each step was recorded as it happened.

28 AugustQuote sent — £6,400
Five items, priced. Three optional extras offered alongside it — each with its price, so nothing had to be worked out later.
29 AugustQuote accepted, deposit received
£1,900. The agreed figure is locked from here.
1 SeptemberWork started, first photos taken
3 SeptemberCustomer chose the heated towel rail — £200
The price had been on the quote since 28 August. She picked it from the list herself. Nothing to argue about later.
30 AugustTwo extras declined — recorded, not deleted
Underfloor heating had to be decided before tiling started. Asking early meant it was a choice, not a missed chance.

That is the whole thing

We are still working out whether this is genuinely useful on a real job, or whether we have invented a step nobody needs.

Would this workflow be useful on your next bathroom project?

Which step is missing, and which one is unnecessary?

Example job. The customer, address and figures are made up; the photos are stock. Nothing here is a real customer record.
