A Counter POS That Understands Repairs

Retail POS is built around a completed sale: scan, pay, done. A repair counter's most important state is the incomplete transaction — devices in the shop, money partly collected, work partly done.

Force that into a retail POS and shops end up running two systems: the POS for accessories and a notebook for repairs. The notebook is where the money goes missing.

The end-of-day question is simple: does the cash in the drawer match what the system says was collected in cash? Getting a truthful answer requires every payment method to be recorded distinctly, including the UPI payments that never touch the drawer at all.

Discrepancies are then attributable — to a counter, a user and a time window — which is a very different conversation from discovering a monthly shortfall with no way to trace it.

Cases, tempered glass, cables and chargers routinely carry better margins than the repairs themselves, and they are the easiest thing to sell to a customer already at the counter collecting a device.

Because accessory stock sits in the same inventory as spare parts, the margin those sales contribute shows up in the same profit reporting rather than being tracked separately or not at all.

The handover moment is the one with the highest conversion in the whole shop: a customer who has just had a screen replaced is more receptive to a tempered glass than at any other point. Having the accessory on the same screen as the balance collection is what makes that sale happen rather than get forgotten.

Repair shops routinely hold money for work not yet done. An advance taken at intake is cash in the drawer against a liability — a device you still owe someone — and treating it as revenue overstates how the shop is doing.

Keeping advances distinct from completed sales gives a truthful daily figure: what was actually earned today, and what is being held against open tickets. Owners who conflate the two tend to discover the gap during a slow month.

It also makes refunds clean. A customer who declines the repair after an advance gets a documented reversal against the original receipt rather than an informal cash handback nobody recorded.
