Bookkeeping and controller services in Seattle.
Clean monthly books and controller-level insight for growing Seattle businesses. Remote-first, on your schedule, with the same team every month.
Built for how Seattle actually operates.
Seattle is technology and software, maritime and logistics, construction, and a substantial base of professional services and consumer brands.
From Bellevue and Redmond across to Tacoma and Everett, businesses are scaling into complexity their books were never structured for.
Common Seattle industries we work with: technology and software, maritime and logistics, construction and trades, professional services.
What we do here
The same service lines as every market. Nothing about the work changes with the postcode — what changes is what your books have to cope with.
Bookkeeping
Monthly reconciliations, a clean chart of accounts, and a close you can rely on.
Bookkeeping →Controller
Close ownership, margin visibility, KPIs, and driver-based forecasting.
Controller →Strategic Planning
Operating plan, rolling forecast, and scenario modelling.
Strategic Planning →Systems & Automation
QuickBooks, payroll, and AP/AR connected so data stops being re-keyed.
Systems & Automation →Washington taxes gross receipts, not profit
Washington has no income tax, but the B&O tax applies to gross receipts by activity classification — and different lines of business are taxed at different rates. That means revenue has to be categorised by activity in the books, not just totalled.
For businesses with more than one revenue line, misclassification is the common failure. It is a chart-of-accounts decision made at setup, and correcting it later means reworking history.
Where your books get complicated
We organise by how a business gets paid, because that is what decides how the close actually works.
Frequently asked
Do you serve businesses outside metro Seattle?
Yes. We support clients across the Puget Sound — Bellevue, Redmond, Kirkland, Tacoma, and the wider region. Engagements run remotely with calls on your schedule.
Do you handle tax filing?
No. SyncBooks is not a CPA firm and does not file returns. We keep the books in the condition your CPA needs and work alongside them. Tax filing stays with them.
Can you work with our existing bookkeeper?
Often, yes. Some Seattle clients keep an internal person for day-to-day entry and bring us in at the controller level above them.
What software do you work in?
Primarily QuickBooks Online and Desktop, where we hold ProAdvisor certification. We also handle migrations between platforms.
How does pricing work?
Pricing is scoped to the work rather than billed hourly, and quoted after we have looked at the books. Cleanup of historical records is quoted separately as a one-time piece.
