Contractor books are harder than most. Money comes in by draw or progress payment, costs land on jobs weeks apart, subs need 1099s, and a single profit and loss statement can hide one losing job behind three good ones.
Every firm on this list states on its own website that it works with contractors, trades or construction businesses. We checked each site in September 2026 and noted what each one says it offers, including job costing, cleanup and whether it prepares tax returns.
For background before you talk to anyone, read our guide to job costing for contractors or our construction and trades page.

Questions to ask a contractor bookkeeper
- How do you set up job costing in QuickBooks, and who enters costs against each job?
- Do you handle progress billing or retainage, or should I ask my accountant?
- Will my books be ready for my tax adviser, lender or bonding agent at year end?
- Do you prepare tax returns, or work alongside the person who does?
- What does cleanup cost if my file is months behind?
Where bookkeeping stops and your tax adviser starts
A bookkeeper keeps the records. Decisions about entity type, depreciation on trucks and equipment, revenue recognition on long jobs and anything a surety needs audited or reviewed belong with a tax adviser or accounting firm. Ask your tax adviser what they want from your books and share that list with your bookkeeper.
