Mechanic invoicing software

Invoicing software built for mechanics

Between the diagnosis, the parts run, and the next car on the ramp, the paperwork always comes last. ServiceInvoice turns the jobs you log into clean, branded invoices in minutes, so you get paid for the work without losing an evening to admin.

No credit card required to start.

Why mechanics use ServiceInvoice

Built for sole and mobile mechanics and small garages who bill parts and labour, not the office.

Parts and labour as separate lines

Parts, fluids, consumables, and your time each get their own line item, so the customer sees exactly what they paid for and you protect your margin on parts.

Diagnostics or fixed-price repairs

Bill a diagnostic check by the hour, or send a fixed-price invoice for a service or repair. The invoice adapts to how you quoted the work.

Tax handled, payment tracked

Tax is applied automatically where it applies, invoice numbers run in sequence, and your dashboard shows which jobs are still unpaid so nothing is forgotten.

Bill every kind of repair

By the hour or fixed price, a quick diagnostic or a full service. The invoice adapts to how you actually charge.

  • Diagnostics and fault-finding billed by the hour
  • Fixed-price services, repairs, and MOTs
  • Parts, fluids, and consumables marked up cleanly on their own line items
  • Repeat work for fleets and regular customers, invoiced fast

Invoicing is just one part of it. ServiceInvoice also keeps your customers and job history in one place. See the full business software, or see how it works for appliance repair businesses.
