How it works

Set up once. Filed every year.

Step 1

Add your accounts

Import your bank and card transactions and tell us about your company and owners. We build your filing calendar the same day.

Step 2

Books kept every month

AI categorises each transaction. An accountant checks the close and asks you only about what is unclear.

Step 3

Returns filed on time

We prepare your federal and state returns and foreign-owner forms. A second accountant reviews them before filing. Licensed CPA or EA review is coming soon.
