Client Onboarding for Accounting Firms: A Step-by-Step
Invite, KYC, engagement letter, first job — a standard onboarding flow for accounting firms.
Why this matters
Australian and New Zealand tax and accounting firms are under more pressure than ever to deliver faster, safer client work. Client Onboarding for Accounting Firms sits right at the centre of that — get it wrong and clients drop off, deadlines slip, and risk goes up.
What to look for
Look for tools that are AU/NZ-aware out of the box (ABN, TFN, ACN, BAS, PAYG; NZBN, IRD, GST, PAYE), enforce per-firm data isolation, have a real audit log, and let your clients do the work in their browser without installing anything.
