Send professional invoices from every callout
A locked-out tenant at midnight, a snapped cylinder at 7am, a re-key for a new landlord — none of it leaves much time for admin. ServiceInvoice lets you log the job on your phone and hand over a finished invoice before you leave the property.
No credit card required to start.
Why locksmiths use ServiceInvoice
Designed around the way locksmiths actually work: on the road, van stocked, invoicing between jobs rather than at a desk in the evening.
Cylinders and hardware billed apart from your time
A euro cylinder, a multipoint lock, or a set of cut keys each sits on its own line next to your callout labour, so a landlord or letting agent can see the hardware cost at a glance.
Invoice from the doorstep, not the office
Add the callout charge, the lock you fitted, and the time you spent on site while you are still standing outside the property, then email the PDF before you drive to the next job.
Nothing left chasing you down
Tax is calculated on every invoice automatically, each one is numbered in order, and a single screen shows which customers still owe you, so a late-night lockout never falls through the cracks.
Bill every kind of locksmith job
An out-of-hours emergency prices differently to a scheduled security upgrade, and ServiceInvoice handles both without you rebuilding the invoice from scratch.
- Out-of-hours lockouts with the emergency callout fee shown clearly
- Lock and cylinder changes priced per door
- Full re-keys and master key system upgrades quoted as one job
- Standing accounts for letting agents billed on a regular schedule
An invoice is only the final step — ServiceInvoice also remembers every customer address and past job, so a repeat callout takes seconds to raise. Learn more about the business software underneath it, or compare notes with our electrician invoicing software.
