Find your path

Pick the door that fits you.

Whether you run a practice, file for your own company, or build the apps that do it for everyone else — Robocount has a front door built for you.

Why accountants switch

The things your old software won't do — now standard.

Robocount gives every plan the full product — every supplementary page, every relief, every client type. You're paying for how many returns you do, not which tax features you're allowed to use.

01

One bill. The whole team.

Unlimited users on every plan — no per-seat upgrades, no module unlocks, no surprise renewal uplift. A 3-staff practice filing 35 returns a year pays £468 flat, regardless of how the firm grows.

From £19/mo · saves £356/yr in user fees alone
02

Rapidly ready for review.

Import a trial balance from Xero or drop in a spreadsheet. Robocount maps every figure, computes the tax, and flags the problems before you spot them. No retyping, no form-by-form clicking.

Draft returns in a fraction of the time
03

Nothing to install, ever.

Open a browser, sign in, carry on. HMRC form changes land automatically — no patches, no "it's not working" calls, no annual re-activation. Mac, PC, iPad, the one in reception.

Zero IT overhead
04

AI handles the drudgery.

Describe an expense, it classifies it. Paste a P&L, it populates the return. The AI prepares — you review, you approve, you file. Included on every plan; no per-query metering.

You get the final say on every AI recommendation
05

Every figure, fully traceable.

Click any number on the return to see the calculation, the legislation it rests on, and what depends on it. Override anything — the impact cascades in real time. Sign off with evidence, not hope.

Full audit trail on every line
06

Filed direct with HMRC.

Officially recognised Corporation Tax software. Returns go straight through the Government Gateway — the same pipeline the big incumbents use, same HMRC receipt in your inbox.

HMRC-recognised · Gateway submission
HMRC supplementary pages

Detailed CT600 supplementary page support.

Robocount handles complex CT600 work as first-class tax logic, not as a loose attachment. Explore the supported supplementary pages for loans to participators, group relief, R&D, creative industries, RPDT, and more.
