A Dedicated Accountant Your Firm Supervises
One named person on your client files, working to your chart of accounts and your close calendar, with a named reviewer checking the work before it reaches you. You keep the engagement letter, the admin rights and the final sign-off. Try it on a real client for 40 hours before committing to anything.

Some firms would rather the work arrived finished and unbranded, ready to review and release as their own. We run those engagements too — you hold the engagement letter, the pricing and the final sign-off, and the client sees only your firm. Named reviewers, published credentials and wholesale monthly pricing.
