Job costing and monthly bookkeeping
We help track project costs, reconcile accounts and organize accounts payable and receivable so job information has a place in your financial reports.
Construction bookkeeping
We help contractors bring job costing, payroll, certified payroll and sales tax records into one back-office workflow. Our team works remotely with the project and financial information you provide, with meetings at our Atascadero office by arrangement.

Project bills, payroll runs and customer payments can end up in separate places. Bookkeeping for contractors starts with consistent job information and a clear record of the costs and payments connected to each project.

Yes. We help with DIR eCPR, WH-347 reporting and fringe benefit tracking alongside monthly bookkeeping and payroll. You provide the project information, applicable wage rates and classifications.
We can organize invoices alongside the project commitments you supply. Keeping those records distinct helps management review costs that have not yet reached the books.

Tidwell Bookkeeping has been part of the Semmes & Co Team for over a decade. They are solid as a rock, making my job easier. With the extensive reporting and legal filings required these days, it is relieving to have their vast experience driving these deliverables, enabling my corporation to operate confidently and without penalty. I speak of the level of competence at Tidwell Bookkeeping with great enthusiasm, however, I certainly would be remiss if I failed to mention how absolutely pleasant and upbeat their staff remains and what a positive impact that has on the morale of my entire team. I would emphatically refer Tidwell Bookkeeping to anyone looking to kick their business up to the next level of professionalism.
