We handle monthly bookkeeping, tax preparation, payroll, and IRS representation for small and mid-sized businesses.

Canyon County Businesses We Work With
Canyon County has changed a lot in recent years. Population growth, new construction, businesses relocating from Ada County. But the agricultural base that built this valley remains. Dairy operations, row crops, cattle ranches, and the food processors and trucking companies that support them. Our clients reflect that mix of established agricultural businesses and newer operations serving a growing population.
We work with businesses doing roughly $100K to several million in revenue. Established enough to need professional bookkeeping and tax work, but not so large that a full-time accounting department makes sense.
