30 free tools. One question each. Answered in under a minute.
Checkers, calculators, builders and decoders for tradespeople. No signup. No paywall. Open the one you need, get an answer, get on with your day.
Every tool here is built around a single question a tradesperson actually asks, 'is my pay legal?', 'does this need regs?', `what does this $IRS letter mean?`. They all cite the rule or law they're based on. None of them need you to create an account.
