A small firm, on purpose
We're based in Amboy, Washington — named for the river that runs through this valley — and we work the way our neighbors do: directly, plainly, and with our word as the contract.
Our story
Built for the businesses big firms overlook
Most of the businesses around here don't need a downtown accounting firm. They need someone who picks up the phone, knows Washington's rules for small business and the trades, and keeps the paperwork moving so the actual work can too.
That's the gap Lewis River Services was built to fill. We keep our client list small enough that you work with the same person every time, and our overhead low enough that careful, personal work stays affordable.
Straight dealing
Plain-language scopes, honest recommendations, no surprise invoices.
On time, every time
Deadlines are the whole point of this work. We track them so you don't.
Careful with your data
Your records are handled with the discretion your business deserves.
Local by choice
Serving Clark & Cowlitz Counties and greater SW Washington.
