Paperwork and disclosure

If any part of the work goes to an outsourced provider, the engagement letter is where AICPA members usually place the third-party disclosure, using language such as the AICPA’s published sample. Where tax return information is involved, the 7216 consent is a separate signed document.

Opening balances

Agree every opening balance sheet account to a statement or schedule before coding the first month. An unexplained opening difference costs more to fix in month six than in week one.

Set up the recurring work

HelloBooks Practice lists client import from CSV, recurring tasks and milestones, and deadline auto-scheduling as live, so the monthly checklist and filing dates can be scheduled at onboarding rather than remembered later.

FAQ

Frequently asked questions

Can we migrate clients from another practice tool?
HelloBooks Practice’s CSV importer detects column headers from common practice tools and generic exports, with a dry run before import.
What should the client do in week one?
Sign the engagement letter, connect bank feeds and send the prior-year return. Everything else can follow.
