Seattle, WA · King County
Outsourced controller in Seattle for contractors, remodelers & developers
Seattle projects sit on top of Seattle Business License Tax, state B&O, and King County permitting timelines that most out-of-state controllers get wrong. We own the monthly close, WIP, and compliance so your team can keep building.
Controller-level oversight built for Seattle construction
Between Seattle's city B&O classifications, complex sales-tax rules on construction, and lenders who expect real WIP schedules on Ballard, Capitol Hill, and West Seattle projects, controller-level oversight is where things fall apart for growing GCs. We build the monthly rhythm — reconciliation, job costing, WIP, filings — so your books hold up for banks, bonding, and your CPA.
What our Seattle outsourced controller handles
Scoped to how Seattle contractors, remodelers, and developers actually build.
King County job costing & WIP
Per-job cost tracking wired through QBO, Buildertrend, or Jobtread — with monthly WIP that ties out for lenders and bonding.
Lender & investor reporting
Clean P&L, balance sheet, WIP, and cost-to-complete packaged monthly so Seattle-area banks and investors don't slow your next draw.
Sub compliance for dense job sites
W-9s collected as subs are hired, retainage tracked, and 1099s filed in January — critical when you're rotating dozens of subs across Seattle sites.
Sales tax on retail vs. wholesale work
Prime vs. sub, reseller permits, and Seattle destination rates coded correctly so audits don't surface surprises.
Cash flow ahead of draw cycles
Rolling 12-week cash view so payroll and materials never wait on a slow draw or a delayed change order.
Best fit for Seattle firms like these
- General contractors running concurrent Seattle jobs
- Real estate developers with multi-entity King County projects
- Custom home and remodel builders scaling past $1M
- Firms whose in-house accountant just left
