Onsite Computer Repair Invoicing App for a Solo Tech (2026)
A solo onsite computer tech needs three things on every job: an hourly or flat labor rate, parts at your price, and a trip charge for showing up. ShowTheReceipts ($15/mo) saves those as a catalog, builds the invoice on the kitchen table before you pack up, and takes the card on the spot — no ticketing queue, no parts inventory, no shop counter to run.
How we picked
Entry-plan prices as published in 2026, taken from each vendor's own pricing page or a recent third-party summary. Judged on the mobile solo technician's actual workflow — labor plus parts plus trip charge, invoiced and paid at the customer's house — not on retail shop management, POS, or parts inventory.

The shop-software trap
Search “computer repair software” and you’ll get ticketing queues, POS terminals, and parts inventory. Every one of those is built for a storefront with a counter — if your shop is a car and a bag of tools, none of it really applies to you.
What a mobile tech actually needs is smaller and faster: quote the visit, bill the work, take the card, drive away.

The four lines every onsite invoice needs
- Diagnostic — quoted up front, credited if they proceed
- Labor — hourly or flat, stated before you start
- Parts — at your price, itemized
- Trip charge — printed every time, waived visibly if at all
Recurring clients are the whole business
One-off “my laptop is slow” calls don’t really compound. Small offices on a monthly arrangement do, and the only way that bills cleanly is if each visit was already itemized under the client when it happened.
Frequently asked questions
Do I need shop software if I have no shop?
No. Ticketing queues, parts inventory, and POS are built for a counter with walk-ins and a shelf of stock. A mobile tech's whole problem is quoting a visit, billing labor and a part or two, and collecting before driving off — that's an invoicing workflow, not a shop system.
How should I bill diagnostic time?
As its own line, quoted up front, and credited against the repair if they go ahead. Free diagnostics is how a tech ends up spending ninety minutes on a machine the customer then decides to replace.
Should I charge a trip fee for a house call?
Yes, and print it every time even when you waive it. A visible trip charge that gets discounted is a favor the customer can see; one that never appears is just free driving.
Can I bill a small business client monthly instead of per visit?
Yes — save the client, add each visit's labor and parts as you go, and send one invoice at month end. Recurring small-business work is where a solo tech's income actually stabilizes, and it only works if the record of visits is already itemized.
