    Construction accounting in Auburn, WA

    Construction accounting is its own discipline. Revenue arrives in draws, costs land weeks after the work, and a job that looked profitable at bid can quietly lose money by close-out. We keep costs tied to jobs in real time so you know where you stand before the project ends.

    Why Auburn construction companies work with us

    From warehouse build-outs along the valley to residential neighborhoods and downtown revitalization, Auburn contractors need job costing that works across project types. We reconcile accounts monthly and keep WA B&O and sales tax filings on schedule.

    We're a Washington-based accounting team specialized in construction and real estate. That means we already know how King County permitting timelines, WA B&O classifications, and local sales tax rates hit the books of construction companies — no ramp-up period, no explaining your industry to a generalist.

    What goes wrong in construction companies' books

    Job costs land in the wrong month

    Supplier invoices show up 30–60 days late and get coded to whatever job is open. We accrue costs to the job and period they belong to, so your margin isn't a moving target.

    Retainage sits untracked

    Retainage held on your receivables and owed on your subs rarely shows up correctly in QuickBooks. We track both sides so your balance sheet reflects what you're actually owed.

    WA sales tax on prime vs. sub work

    Retail sales tax applies differently to prime contractors, subcontractors, spec builds, and public works. Miscoding is the most common finding in a Washington DOR audit.

    Construction accounting FAQs

    Do you handle percentage-of-completion accounting?

    Yes. We maintain WIP schedules with earned revenue, over/under billings, and cost-to-complete so your financials satisfy bonding agents and lenders.

    Can you work inside our existing software?

    We work in QuickBooks Online alongside Buildertrend, Jobtread, or Jobber. If you're on QuickBooks Desktop, we can migrate you on a fixed fee.

    Do you meet with clients in Auburn?

    Most of our work is remote, but we're based in the Puget Sound and regularly meet Auburn-area clients in person when it helps — onboarding, year-end review, or a lender meeting.
