A till where every sale stays on record
What was sold at an appointment used to be scattered all over Stippa. Now every appointment has one receipt, and you fix a mistake with a new line instead of an eraser.
Until this week, Stippa couldn't answer a simple question very well: what was sold at this appointment, and has it been paid? The treatment was on the appointment. Products sold were somewhere else. An extra charge wasn't anywhere. And payments had a little list of their own. All separate, like socks after the wash.
For a calendar, you can live with that. For a till, you can't.
One receipt per appointment
From now on, every appointment has one receipt. It lists the treatment, the products, any extra charges and discounts, and at the bottom what's been paid and what's still open. At the counter, that's also the screen you work in: add a line, give a discount, take payment.
Every receipt gets a number, per salon, with no gaps. Even if something goes wrong in between, no number goes missing. That unbroken sequence is exactly what you want when your books need to add up later.
No eraser, a correcting line
A finished receipt can't be edited. If you rang something up wrong, you reverse it with a correcting line. The old line simply stays, struck through, with the correction underneath.
That may feel roundabout at first. But it's how a till should work: you can always see afterwards what happened. The technical term is append-only (opens an external site): you can only add to it, never erase anything. So a sale can't quietly disappear.
Who did what adds up now too
A nice bonus shows up in revenue per staff member. It used to be split by the time each person spent on an appointment. If one colleague did the cut and another the colour, the one who cut got part of the colour on their name. Unfair, and not much fun at review time. Now every line on the receipt belongs to the person who did it, and the split is right.
There's more on how Stippa is put together in the case study.
