Built by operators.
Powered by AI.
Most bookkeeping firms are built for the firm, not the client. Hourly billing, locked-in annual contracts, books done somewhere you can't see them, and a year-end scramble that nobody enjoys. We thought it could work better.
Yesler was founded by operators who came from the payroll, accounting, and professional services world — including experience across companies like ADP and KPMG. After years of seeing how slow, expensive, and fragmented traditional back-office support was for small businesses, we built a more modern model: AI-assisted workflows, dedicated human review, and senior oversight, all under one roof.
We use AI to reduce the repetitive work that traditionally makes bookkeeping slow and expensive — categorization, document matching, anomaly detection, reconciliation prep. Then we layer in human review and senior oversight to make sure the work is accurate. The result is a faster, more transparent back office that costs less than the old way, without cutting corners.
Everything is checked through a layered process. AI handles the first pass. A staff specialist — bookkeeper, payroll, or tax — reviews the work and handles edge cases. Senior management or an in-house CPA gives final review before anything is finalized. That's three layers of review on every engagement.
You see every step in the Portal. What AI flagged, what your specialist corrected, what senior review caught. No black boxes, no "just trust us" billing, no wondering where your books stand at any given moment.
That's the entire pitch. A team that takes the back-office work off your plate, using AI to keep it affordable and human review to keep it accurate — so you can get back to what you're actually here to do.
Three things we won't compromise on.
AI does the boring work.
Categorization, document matching, anomaly detection — the parts of bookkeeping that traditionally make it slow and expensive. AI clears the runway so our team can focus on judgment calls, not data entry.
Humans check everything.
Every engagement runs through three layers of review: AI first pass, staff specialist review, and senior or CPA sign-off. Your books aren't trusted to one person — or to AI alone.
Clear quotes, no surprises.
Every business is different, so we quote based on your transaction volume, cleanup needs, payroll complexity, tax requirements, and reporting needs. You'll get a clear monthly quote before work begins. Month-to-month — cancel any time.
