Plumbers: your books, closed by the fifth business day.
Quick answer
For plumbers, TrainedBooks is automatic bookkeeping software that closes your books by the fifth business day. It sorts every bank and card transaction for you with a plain-English reason, shows your real profit and a location-aware tax set-aside (real federal + your state's rates), and prepares a tax-ready package so your tax pro just reviews and files. You review the few flagged items and own an exportable ledger. From $35/mo, with a free start, no card required, and a 30-day money-back guarantee — bookkeeping software, not a tax preparer.

Plumbing contractors and one-truck service businesses. TrainedBooks categorizes every parts run and service deposit with a reason you can check, closes the month by the fifth business day, and shows your real profit plus what to set aside for taxes.
The problem
Service calls, emergency jobs, and parts runs all hit one card — supply house, fuel, dispatch software, insurance — and by month-end the only number you trust is your bank balance.

Bookkeeping for plumbers — FAQ
Parts and personal spending are on the same card. Can it tell them apart?
TrainedBooks categorizes each line with a confidence and a reason, learns your corrections, and flags what's genuinely ambiguous for a quick yes/no — so supply-house runs stop landing in the wrong bucket.
What about slow months? I need to know what to save for taxes.
Every close updates a monthly tax set-aside target based on your actual profit and how your business is taxed, so a strong month saves more and a slow month doesn't over-reserve.
Do I need to switch away from my dispatch or invoicing software?
No. TrainedBooks works from your bank and card activity (or CSV exports), so it sits under whatever you use to run jobs and gives your CPA a clean, file-ready packet.
