Traffic Control and Flagging Services Invoicing App (2026)
Traffic control is billed as certified flagger hours plus device rental — cones, barricades, arrow boards, message boards — with mobilization, permits, and traffic control plans as separate lines, invoiced to contractors and municipalities on terms. ShowTheReceipts ($15/mo) saves flagger and device rates, invoices by job site and date with the PO referenced, and gets the invoice out while the crew's timesheets are still fresh.
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 traffic control company's workflow — flagger hours with minimums and OT, device rental, per-site invoicing with PO references, and fast turnaround against weekly payroll — not on DOT permit portals, traffic engineering CAD, or fleet telematics.

Labor plus rental, on someone else’s schedule
Flaggers are hourly labor; devices are daily rental. Both keep running while a contractor waits on a utility crew or an inspector who hasn’t shown up yet.
Companies that bill both accurately tend to do well. Companies that bill the hours and forget the devices leave a quarter of their revenue sitting in the field.

- Device rental — cones, barricades, signs, per day or week
- Arrow board / message board — per day
- Truck-mounted attenuator or shadow vehicle — per day
- Traffic control plan preparation — flat
- Permits — at cost
- Mobilization and setup / teardown
Reconcile deployed devices weekly
A barricade standing on a shoulder for three extra days is three unbilled rental days. Reconciling what’s deployed against what’s invoiced, every week, is probably the highest-return admin habit in this business.
Bill the wait
Utilities run late, inspections slip, and weather stops work, and your flaggers are standing in the road for all of it. A stated standby rate is normal here, and expected.
Match the municipality’s format before the first invoice
PO numbers, prevailing wage documentation, specific line formats — get the requirements in writing at award, not after your first invoice has already been rejected. Public payment cycles are slow enough without restarting them.
Frequently asked questions
How is traffic control priced?
Certified flagger hours with a minimum — commonly four or eight — plus daily or weekly rental on every device deployed, plus mobilization. The devices are the recurring revenue; the flaggers are the labor line.
What's most often under-billed?
Devices left on site. Barricades, cones, and boards standing for three extra days are rental days nobody logged. Reconcile deployed devices against invoices weekly — it's the single largest recovery available in this trade.
How should standby and delays be handled?
Billed at the flagger rate. Crews wait for utilities, inspections, and weather constantly, and the flaggers are on the clock the entire time — a stated standby rate is expected by every contractor you'll work with.
Do municipalities pay differently from contractors?
Slower and more formally — PO required, specific invoice formats, sometimes prevailing wage documentation. Get the requirements in writing before the first job and build the invoice to match, or the first payment takes a quarter.
