business day

- Answers within one business day
- Easy to switch
- One team, one number to call

Sound familiar?
You run a busy business. Your numbers shouldn't be a mystery.
- You're busy every week, but you're not sure you're actually making money.
- You need an answer before a big decision, and your accountant takes days to call back.
- A tax bill shows up in April and wipes out cash you'd planned to use.
- Your evenings and weekends go to receipts and paperwork instead of your family.
None of that means you picked wrong. It means your accountant is juggling too many clients.

What's changed
Accounting firms are stretched thin.
Many are short on staff, raising fees, or selling to private equity. Smaller clients feel it first, through slower replies and less attention. The fix isn't fighting for your current accountant's time. It's moving to a team with room for you.
Why Blackfin
Know what you made. Know what you owe. Get answers fast.

Moving from your current accountant sounds like a hassle. We do the legwork, so you don't have to.
One team
Your books, taxes, and payroll handled by one team. One number to call, and nobody pointing fingers.
Built for service businesses
Your business sells skill and time. We show you which jobs, cases, chairs, or deals actually make you money.

A note from Chris
Before Blackfin, I spent twelve years building and running an IT company here in Bozeman. What I wanted most from my accountant was simple: answers when I needed them, and help planning ahead. I built Blackfin to be that team for other service business owners. And with a background in IT and cybersecurity, we take care of your data the way it deserves.
