Bookkeeping Services in Seattle, WA

Clean books, every month — so your business runs on real numbers and tax time isn't a fire drill. Monthly bookkeeping, year-end cleanup, and QuickBooks Online setup, all done by a tax-trained accountant who knows what April will need.

In a metro of 749,256, small and mid-size operations in Seattle, Washington face the same bookkeeping pressure as larger competitors — monthly closes that actually close, bank reconciliations that match to the cent, and year-end financials a lender or tax preparer can rely on. (Local economic context: Technology (Amazon, Microsoft), aerospace (Boeing), no state income tax.) CS Precision Tax works primarily in QuickBooks Online: chart-of-accounts setup, bank and credit-card feed connections, monthly transaction categorization, account reconciliation, and delivery of profit-and-loss and balance-sheet statements — without being prompted. Washington levies a state sales tax. We coordinate with your payroll provider (Gusto, ADP, Rippling) and sales-tax tool (TaxJar, Avalara) so the general ledger reflects what those systems report. Owner draws, contributions, and distributions are tracked in dedicated equity accounts from day one, which matters for basis calculations in S-corps and partnerships operating across King County. Year-end cleanup for businesses that need catch-up work before tax preparation is quoted separately as a fixed-fee engagement.

What to know if you file from here

For businesses in Seattle, King County, the most common bookkeeping gap is failing to segregate WA sales tax collected from gross operating revenue. Washington levies a state sales tax. Monthly reconciliation is the only reliable way to catch the small discrepancies — duplicate charges, misrouted payments, uncategorized receipts — before they compound into year-end balances that slow down tax preparation. Owner-equity accounts for S-corps and partnerships operating in Seattle should be structured from the start so basis calculations are straightforward at filing time.

Frequently asked questions for Seattle, WA

Can you handle bookkeeping for my Seattle business if we never meet in person?
Entirely remote is how we work. You connect bank and credit-card feeds through QuickBooks Online — read-only access — and we close the books each month, reconcile every account, and deliver statements on schedule. The process is identical for businesses across King County and throughout Washington.
Our Seattle company's books are behind by a year or more. Can you catch us up?
Yes. Prior-year catch-up and year-end cleanup are fixed-fee engagements scoped after a diagnostic review of your QuickBooks Online file. We identify miscategorizations, reconcile all accounts to bank statements, and produce return-ready financials. For King County businesses preparing for a loan, a sale, or a clean WA filing, this is typically the first step.
