Bookkeeping, job costing, sub paperwork and change orders for contractors. Certified QuickBooks ProAdvisor with 20+ years in construction operations.
Hi, I'm Tammy Finn
I'm the back office for contractors who'd rather be on the job site. I spent 20+ years in construction operations: running install crews, managing procurement and a service department, and working with subs on windows, house wrap, access control and CCTV. I've also spent nearly 10 years leading ERP conversions, and I'm a Certified QuickBooks Online ProAdvisor.
What I handle: bookkeeping and job costing in QuickBooks Online, sub paperwork (W-9s, insurance certificates, lien waivers, 1099s), change orders that actually get billed, and simple written processes so your office runs the same way every time. You'll know which jobs make money, and your paperwork won't be the thing that bites you. No jargon, no judgment on how messy it is right now.
How I Help Contractors
01
Books & Job Costing
Books closed every month in QuickBooks Online, plus a job profit report that shows which jobs made money and which didn't.
02
Sub Paperwork
W-9s, insurance certificates and lien waivers on file and current, and 1099s ready in January. No scrambling when the auditor calls.
03
Change Orders & Purchasing
A simple change order process so extra work gets billed, and a purchasing process so every bill matches an order.
04
Office Setup
Written step-by-step processes for how your office runs, so it works the same way every time, even when you're on a job site.
