Client Portal for Accountants

One secure place for your clients to view documents, sign forms, and pay invoices — for a flat monthly fee, with no per-user and no per-client charges. Set up in about 20 minutes, on top of the accounting software you already use.

Why your firm needs a client portal

Every week, accounting firms spend hours emailing documents, chasing signatures, and following up on unpaid invoices. A client portal removes that friction by giving each client a secure, branded space to manage everything in one place.

Clients log in anytime to view documents, sign engagement letters electronically, pay invoices with one click, and message your team directly. No more lost emails or version confusion. And because the portal sits on top of your bookkeeping, you keep Xero or QuickBooks for the books — the portal handles everything client-facing.

A flat fee — no per-user, no per-client pricing

Most client portals for accountants charge per user or per client, so your bill climbs every time you hire or onboard a client. For a small, growing firm that adds up fast. FirmFlow is a flat monthly fee — one price whether you are a sole practitioner or an eight-person firm, with ten clients or two hundred. It is the pricing model built for small firms that intend to grow.
