You shouldn't have to think about your books.

You don't need to hire a bookkeeper or figure out QuickBooks. We learn your business, set up AI agents for your workflows, and handle your books every month.

99%+ transaction accuracy

Our AI categorizes transactions better than a human bookkeeper.

We learn your business patterns and apply them automatically. Connect your banks and tools—we handle the rest. Our team reviews everything before closing each month.

Costs less than a traditional accountant

Traditional firms bill you for manual work. We built AI to do that part.

Our AI handles the repetitive transaction work that used to take hours. You're paying for expertise and oversight, not data entry. That's why we can charge less and deliver more.

Text us when you have questions

We're a US-based team and we actually respond.

Since we're not spending all day on data entry, we have time to help you understand your numbers when you need it. Text, call, or email—we're here.

HOW IT WORKS

Accurate books without the busywork

Connect your accounts and we take it from there. Our AI categorizes transactions and reconciles your accounts—99%+ accuracy. Our team reviews everything before we close each month. You get clean financials, on time, without thinking about it.
