Businesses today face a painful middle ground. Traditional accounting firms are expensive, slow, and not built for your size. Pure AI tools are fast — but they make errors and lack the judgment to handle real-world complexity.
Collar Assist is built for what comes next: the speed of AI, backed by the accountability of experienced accounting professionals.
“My books are always a month behind”
We deliver month-end close within 5 business days
“I don’t know if my accountant is making mistakes”
Every AI output is reviewed by a qualified professional
“My current provider doesn’t understand my industry”
We specialize in your sector’s specific accounting needs
We do not believe AI should replace accountants. We believe accountants empowered by AI deliver better outcomes than either alone. That is what Collar Assist is built on.

CEO, IT Industry, Texas, US
Collar Assist has completely transformed how we handle our month-end close. What used to take our team nearly three weeks is now done in under five days, every single month without fail. Their attention to detail and the consistency they bring to our books has given us a level of financial confidence we simply did not have before.
Director of Finance, Manufacturing firm, Colorado, US
Handing over our bookkeeping and payroll to Collar Assist was one of the best decisions we made as a growing business. They understood our industry from day one, kept everything organised and accurate, and never missed a payroll or a deadline. Our accountant actually commented on how clean our records were at year-end and that says everything.
Co-Founder, CPA Firm, Georgia, US
We had tried two other outsourced bookkeeping providers before Collar Assist, and the difference in quality is night and day. The combination of AI-powered processing and professional review means errors get caught before they ever reach us. Payroll runs on time every cycle without us having to chase anything. Our financial reporting is sharper, our cash flow visibility is better, and our team spends far less time chasing numbers.
