Access Control and Door Hardware Installation Invoicing App (2026)
Access control work is billed per door for installation, plus panels, credentials, and labor — then continues as recurring revenue through hosted software, credential management, and service agreements. ShowTheReceipts ($15/mo) quotes per-door builds, converts the approved quote into an invoice, bills the recurring hosted and monitoring lines monthly, and invoices service calls with the door and building identified.
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 integrator's workflow — per-door quoting, deposits on hardware, recurring hosted and service billing, and service-call invoicing with door references — not on credential management platforms, panel programming tools, or enterprise PSIM software, which are the systems being installed rather than the business behind them.

| ServiceM8 | $29/mo+ | Job cards for a small crew |

Install once, bill monthly forever
The install is a project; the system is a subscription. Hosted software, credential management, and a service agreement turn a one-time build into revenue that keeps going at every site you’ve ever wired.
Integrators who skip that part start each year back at zero.

The lines an access control invoice needs
- Per-door install — reader, lock hardware, power, wiring, labor
- Panel and controller — with capacity stated
- Power supplies, batteries, and enclosures
- Door hardware — strikes, maglocks, exit devices, power transfer
- Credentials — cards, fobs, mobile licenses, per unit
- Software licensing — one-time or per-door
- Hosted / cloud subscription — monthly, per door or site
- Programming, commissioning, and training
- Service agreement — monthly or annual
- Service call — labor with after-hours premium, door identified
Quote per door and you find the problems
Door 4 needs a power transfer hinge. Door 7 has no path for conduit. Door 9 turns out to be a fire door with hardware requirements nobody mentioned.
A per-door quote surfaces all of that before the job instead of during it.
Credentials are a recurring product
Every new employee is a credential; every lost badge is another. Price cards and mobile credentials as a stocked product with a stated rate, and reordering happens without a quote every time.
Name the door on every service line
Facility clients code invoices by opening. “Reader replaced, Door 12, east lobby” clears; “service call” just waits.
Frequently asked questions
How should access control be quoted?
Per door, as a complete opening — reader, lock hardware, power, wiring, and labor — with the panel, software, and licensing priced at the system level. Customers compare per-door numbers, and a per-door quote is also how you catch that door 4 needs a power transfer hinge nobody budgeted.
Should hardware require a deposit?
Yes. Locks, panels, and readers are ordered specifically for the job and often non-returnable once specified. A deposit covering material is standard in this trade and rarely questioned.
What's the recurring revenue here?
Hosted access software, credential management, monitoring, and service agreements — billed monthly per door or per site. Integrators who treat installation as the whole business rebuild their revenue from zero every January.
How should service calls be invoiced?
With the building, door, and panel identified, plus labor at the applicable rate and any after-hours premium. Facility clients code by opening, and an unidentified door line is the most common reason a service invoice stalls.
