Three numbers to write down before you leave the workshop

Most service records fail in the car park, not at the desk. You pay, you take the paper, and by the evening the only fact you remember is that the car feels the same. The paper is in a door pocket.

You do not need the whole bill memorized. You need three numbers written where you will see them: the date, the odometer printed on the invoice, and the next due date or kilometer figure if the shop wrote one.

The date stops the visit from floating in 'sometime this spring.' The odometer ties the work to the car, which matters more when you own two or when you buy used. The next due figure is the only part of the visit that still needs you later.

Cost matters too, and it is on the same page. If you can only hold three things while someone is talking, hold the ones that are hardest to recover. You can read the total again from the paper. You cannot recover an odometer the invoice never showed once you have driven away and forgotten to look.

At home, turn those numbers into one service row: what they did, the date, the kilometers, the cost, and the next due mark. Attach the invoice. If a line says the work was declined, do not record it as done.

That is the whole habit. RPMBase is meant to shorten it, first with a form and then with a draft from the photo or from a sentence, always with a confirmation step. The habit still starts at the counter.

If you want the slower version, the guide to reading a service invoice walks the page line by line. This note is only the part you should not postpone.
