Security Guard Company Invoicing and Scheduling App (2026)
Guard services are billed by post hours at a contracted bill rate, usually weekly or biweekly, with separate rates for overtime, holidays, supervisors, and emergency coverage. ShowTheReceipts ($15/mo) saves bill rates by post and shift type, invoices hours by site and week with the contract referenced, and gets the invoice out the day the timesheets close — which is what keeps payroll ahead of receivables.
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 small guard company's workflow — bill rates by post and shift type, weekly invoicing by site, overtime and holiday lines, and fast turnaround from timesheet to invoice — not on guard-tour verification hardware, incident report systems, or enterprise workforce management, which are separate categories.

Payroll is weekly; receivables aren’t
You pay guards on Friday and get paid in thirty days. That gap is the whole financial reality of a guard company, and it’s why invoicing speed matters more here than in almost any other service business.
A three-day delay between timesheets closing and invoices going out is three more days you’re financing a client’s security program.

The lines a guard services invoice needs
- Regular post hours — per site, per bill rate
- Overtime hours — at contracted OT rate
- Holiday hours — at holiday rate
- Armed post premium
- Supervisor / site lead hours
- Emergency or short-notice coverage — its own rate
- Vehicle patrol — per patrol or per hour
- Equipment — radios, vehicles, uniforms, where billable
- Training or onboarding — for client-specific requirements
Invoice by site, weekly
Multi-site clients reconcile by location, not by total. Hours per site per week, with the contract or PO referenced, is the format that clears — send a single lump total for six properties and it just gets held while someone breaks it down for you.
Bill client-caused overtime
A client who adds a shift on Thursday causes overtime on Friday. That belongs on their invoice at the contracted rate, and it needs to be written into the contract before it happens, not argued about afterward.
Emergency coverage is a premium product
Short-notice posts pull guards from other assignments and often trigger overtime. Price it above your standard rate and quote it as its own distinct service — a client calling at 10pm isn’t price shopping.
Frequently asked questions
Why does invoice speed matter so much in guard services?
Because payroll runs weekly and client terms run 30 days. Every day between the timesheet closing and the invoice sending is a day of your own money funding someone else's post — this is the single most cash-sensitive service business there is.
How should bill rates be structured?
By post and shift type — unarmed, armed, supervisor, overnight, holiday, and emergency — each as its own rate on the contract. A single blended rate always ends up losing money on the hardest shifts to staff.
Should overtime be billed through?
Yes, at the contracted OT rate, when the client's schedule causes it. Absorbing client-driven overtime is a direct transfer from your margin to theirs, and it's the most common structural loss in small guard companies.
Do I need guard tour and incident software?
Tour verification is genuinely valuable at scale and it's a different job from billing. If your problem is slow invoicing against weekly payroll, fix that first — no tour system ever shortened a receivable.
