Feature counts are across the 12 features listed above, based on each vendor's published product pages, help centre and announcements as of October 2026. “Partial” means available in a limited form — in beta, announced as coming soon, a capacity report rather than planning, or through a QuickBooks/Xero integration rather than a ledger of its own — and is not counted. “—” means not found in the vendor's published materials. Products change often; verify current features with each vendor.

Security · the staff sign-in gate NEW

Your login page, off the open internet

Most web software puts its login screen in front of anyone on the internet. OneFirm adds a locked door in front of the login itself: your team passes a separate sign-in gate run by Amazon Web Services before the OneFirm login is even reachable. Bots, AI agents and strangers never get the chance to try a password.

Two locks, two systemsClients' links stay open as always
01 · The gate

Only your staff get through

Google, Microsoft or an emailed code, checked against your firm's active staff list.

02 · Login

Their own password

Or your firm's Microsoft single sign-on.

03 · MFA

A second factor

So a stolen password still isn't enough.

04 · Workspace

Then, and only then

Firm data loads, limited by role and walled off from every other firm.

The argument, in one figure

Same nine jobs.
Same firm.
Sixteen fewer re-types.

In a stack of separate tools, each hand-off between modules is a person reading a number off one screen and typing it into another. Count the crossings.

About OneFirm

Built by people who know how firms run.

01 / 04

OneFirm is the operating system for professional service firms — practice management, bookkeeping, billing and client experience in one secure platform.

Less tool-switching. More time serving clients.

02 / 04

Field-level encryption, database-enforced tenant isolation and in-region data residency protect your clients' most sensitive information.

Enterprise-grade security, by default.

03 / 04

Recurring work generates itself from engagements, statuses advance on triggers, and overdue work is chased for you.

The system does the busywork.

04 / 04

A guided setup with a dedicated specialist and hands-on migration means most firms are live within days.

Because your growth shouldn't wait on software.
