Locksmith invoicing software

Invoicing software built for locksmiths

Between emergency call-outs, lock-outs, and quoting the next job, the paperwork always comes last. ServiceInvoice turns the jobs you log into clean, branded invoices in minutes, so you get paid on site instead of chasing it later.

No credit card required to start.

Why locksmiths use ServiceInvoice

Built for sole locksmiths and small firms who bill on site, not from the office.

Hardware and labour as separate lines

Locks, cylinders, keys, and your time each get their own line item, so the customer sees exactly what they paid for and you protect your margin on hardware.

Bill the call-out before you leave

Log the call-out fee, the hardware fitted, and your labour on site, then send the branded PDF before you pack up, so the emergency job is billed while it is fresh.

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 locksmith job

Emergency lock-outs or planned upgrades, a single repair or a full re-key. The invoice adapts to how you actually charge.

  • Emergency call-outs billed with a clear call-out fee
  • Lock changes and re-keys priced per door
  • Locks, cylinders, and keys marked up cleanly on their own line items
  • Repeat work for letting agents and landlords, 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 compare it with our electrician invoicing software.

Frequently asked questions

Can I invoice emergency call-outs on the spot?
Yes. Log the call-out fee, the locks or cylinders fitted, and your labour on site, then generate the branded PDF before you leave, so the bill goes out while the customer is still there.
Can I separate hardware from labour?
Each lock, cylinder, and key gets its own line item alongside your labour and call-out fee, so customers see a clear breakdown and your margin on hardware stays protected.
Is it free for a sole locksmith?
Yes, you can start on the free plan with no card. Pro adds your logo and higher limits when you’re ready, which suits most one-person locksmith businesses.
