Calculator
First Employee Cost Calculator
A $22/hour employee doesn’t cost you $22/hour. Add employer payroll taxes, workers’ comp, paid time off, and the overhead nobody quotes you. Then see what an hour of their work really costs.
OpenBuilder
First Crew Software Stack Builder
Four questions about your trade, your crew size, and whatever is currently breaking. You get a specific stack, or a nudge that a free template still covers it.
OpenRisk check
1099 or W-2?
Fourteen questions against the factors the IRS actually weighs, plus the state test that decides it outright in California, Massachusetts, New Jersey and Washington.
OpenCalculator
Job Profit Calculator
What to quote so the job actually makes a margin, plus the price below which you are working for free. Includes the markup and margin trap that catches almost everyone.
OpenCleaning
Cleaning Job Pricing Calculator
Prices a clean from square footage, crew size and drive time, then shows how many homes a day you can actually do. Built on how cleaning prices rather than how trades do.
OpenGenerator
Price Increase Letter
The email, the text and something to say out loud when a customer asks why. Warns you when the increase is steep enough that it needs phasing.
OpenGenerator
Review Request Generator
Writes the text, email and follow-up asking a customer for a Google review, tailored to your trade and staying on the right side of Google’s rules.
OpenDiagnostic
Do I need field-service software yet?
Seven questions and a straight score. About half the outcomes say not yet, because at smaller sizes that’s the right answer.
OpenHow we handle tax figures
Payroll tax rates change every January, and a calculator quietly running on last year’s numbers is worse than no calculator at all. So every rate lives in one place, carries the date we checked it, and gets published on the tool’s own page under “Assumptions used”. You can check our working instead of taking our word for it.
Current figures are checked for the 2026 tax year, including the Social Security wage base of $184,500. Spot something out of date and tell us. We’ll fix it.
