How it works

1. Add your clients

Import your self-employed client list in under 2 minutes.

📅

2. We track deadlines

HMRC quarterly deadlines are calculated automatically for every client.

📧

3. We chase clients for you

Automated data requests go out and ProBooks follows up — you just review what comes in.

Everything your firm needs for MTD ITSA

No spreadsheets. No missed deadlines. No chasing clients manually.

📧

Automated email reminders

5-level escalation sequence — friendly nudge at 30 days, urgent notice at 1 day, overdue alert after the deadline. Zero manual effort.

💬

WhatsApp notifications

Clients who prefer WhatsApp get reminders there instead of email. Set preferred channel per client — ProBooks handles the rest.

🔗

One-click client submission

Clients click a link in their reminder and fill in their quarterly figures in 2 minutes — no login, no account, no friction.

📊

Live compliance dashboard

See Q1–Q4, Year-End, and Final Declaration status for every client at a glance. Red means action needed, green means filed.

⚠️

Penalty risk alerts

ProBooks flags clients with 2+ overdue quarters — the threshold where HMRC penalty points accumulate fast. Catch problems before they cost £200 per client.

👥

Team access

Add junior staff as team members. They see the same dashboard and can send manual reminders — without access to billing or settings.
