You don't need another app. You need your books done.
Bookkeeping software still leaves the work to you. We sell the finished result: closed, reconciled books every month. AI handles the repetitive work behind the scenes, and a person reviews and signs off before anything is final.
How it works
Four steps. You only do the first one.
Send receipts & bank access
Connect your bank and card accounts with read-only access and snap or forward receipts. That's your whole job.
We categorize every transaction
AI sorts each transaction into the right account behind the scenes. Anything unclear gets flagged for a person, not guessed.
We reconcile to the bank
Every account is matched to your bank and card statements so the numbers in your books are the numbers in your bank.
You get your P&L, reviewed and signed off
Each month's books are reviewed by our team before they're closed. You get a clear Profit & Loss and a short summary.
Every month, checked off
Know your numbers are done.
Each month gets closed and checked off. When it's time to file taxes, apply for a loan or plan your next hire, your books are already ready.

Questions
What do you need from me?+
Read-only access to your business bank and card accounts, access to your bookkeeping software (or we can help you set one up), and your receipts as they come in. After setup, most months you'll just answer the occasional question about a transaction.
Which software do you work with?+
Clients use their own QuickBooks Online or Xero subscription. We work in your account and can help you set one up if you don't have it yet. If you're on spreadsheets or paper today, we'll help you move to one of them as part of onboarding.
How long does the monthly close take?+
It depends on your transaction volume and how quickly receipts and answers come in. We'll agree on a target close date for each month during onboarding.
Is a person actually checking my books?+
Yes. AI does the repetitive sorting and matching, and every month's books are reviewed by our team before they're marked closed.
Can you catch me up if I'm behind?+
Yes. Catch-up is $150–$200 per past month, depending on how many transactions are involved.
Do you do my taxes?+
Yes. We prepare and e-file business and individual tax returns, built from the books we keep. We don't represent clients before the IRS; if you get an IRS notice, we'll help you gather your records for the licensed professional who handles it.
Can you help me start a business?+
Yes. We file your Florida LLC or corporation on Sunbiz, apply for your EIN, file your annual reports each year, and set up your books from day one. For legal questions about your structure or agreements, talk to an attorney.
