QuickBooks wasn't built for prevailing wage. So the certified payroll gets done by hand, in a spreadsheet, on a Friday night — and one missing fringe line is the #1 thing that triggers a Davis-Bacon audit. Charlie generates the WH-347 from the hours your crew already clocked, statement of compliance and all, while you talk.

The whole back office

Everything the office does — without the office night.

One seat replaces the certified-payroll software, the billing spreadsheets, and a chunk of the bookkeeper.

📋

Certified payroll (WH-347)

The complete filed form — day-by-day grid, deductions, net pay, statement of compliance — generated from the hours already clocked. SSNs masked by default.

⚖️

Prevailing wage

Davis-Bacon and state prevailing-wage packs, wage determinations per job, fringe on all hours, the daily-8 / weekly-40 OT triggers handled for you.

🧾

AIA progress billing

G702 / G703 pay applications with retainage and carry-forward, drafted then frozen on certify — the math done right, every draw.

📜

Lien waivers

Conditional and unconditional, progress and final — the correct statute-cited waiver for your state, generated on demand.

💸

Receivables & retainage

Who owes you, how much retainage is held, and every pay-app and lien deadline tracked so nothing slips past its date.

📊

Job costing + QuickBooks

Labor and receipts roll into real job cost and WIP. Receipts post as expenses and certified pay apps post as invoices — synced to QuickBooks Online.

See the output

A real, filed WH-347 — not a spreadsheet.

The complete Department of Labor certified-payroll form: the day-by-day hours grid, deductions, net pay, prevailing-wage check, and the statement of compliance an auditor asks for. Charlie builds it from the hours your crew already clocked — SSNs masked by default, full export permissioned and audited.

The hard part, automated

The certified payroll nobody else automates.

Every all-in-one contractor app does invoices and scheduling. Almost none of them do a compliant WH-347 with a statement of compliance — the exact document a prevailing-wage job demands and an auditor asks for. Charlie generates it by voice, from the hours your crew already clocked. That's the gap, and it's the one that costs you a contract if you get it wrong.

One seat, real leverage

Replace the stack, not add to it.

Certified-payroll software runs $200–600 a month. A construction bookkeeper runs $350–1,200. Office Manager is $149 and does the compliance work both of them charge for — and answers you out loud.

Made for the people who do the work

Built by a superintendent, for the small shop.

Not enterprise accounting squeezed down to fit you. Charlie was built on real jobsites, for the contractors and office managers doing prevailing-wage paperwork at night because they were running the job all day.

Straight answers

Questions, answered.

Does this replace QuickBooks?

No — it works with it. Keep your books in QuickBooks Online; Charlie handles the construction-specific compliance QuickBooks doesn't (certified payroll, prevailing wage, AIA billing, lien waivers) and syncs receipts and pay apps across. Best of both.

Is the WH-347 a real, filed form?

Yes. It's the complete Department of Labor WH-347 — day-by-day hours grid, deductions, net pay, and the statement of compliance — generated from the hours your crew clocked. SSNs are masked by default; a full export is permissioned and audited.

Which states' prevailing wage do you handle?

The engine is state-agnostic with wage-determination packs — federal Davis-Bacon plus state packs (Washington and Oregon today, more as clients need them), each statute-cited, with the right OT trigger for that jurisdiction.

Do I have to learn accounting software?

No. You talk to Charlie the way you'd talk to your office manager — "generate this week's certified payroll," "draft the pay app." Everything also works by tapping through the forms if you prefer.

Can I start with just Office Manager?

Yes. It's $149/mo on its own. Add estimating, scheduling and the field tools anytime by upgrading to Full Charlie — no migration, your data stays put.

Is my payroll data safe?

Yes. Data is isolated per company on US-based servers, encrypted at rest, and PII like SSNs is masked by default with every reveal access-controlled and audited.
