Say hello to our newest feature

Decision Trees — live and ready to use!

The Magic Behind the Branches: What Is a Decision
Tree?

In simple terms, a decision tree acts as a smart assistant that guides you through tax and accounting decisions by asking just the right questions — nothing more, nothing less. Instead of sifting through dense HMRC guidance, you simply answer a series of targeted questions.

No more guessing. No more flipping between guides and tabs. Just logic, built right in.

How It Works Inside Acting Office

Our Decision Tree feature is set to bring remarkable benefits:

  • Speed: No need to recheck rules each time. Answer and act.
  • Compliance: Aligns with UK tax law and HMRC guidelines.
  • Automation: Reduces manual errors and repetitive input.
  • Scalability Across Your Firm: This isn't just for one-off tasks. Build decision trees that your entire team can use consistently across many clients or complex transactions, standardizing your firm's processes.
  • Audit-Ready: Keeps a trackable decision trail — good for internal reviews or client explanations.

Built-in Safety Net Automatic flagging of incorrect or missing data prevents costly mistakes before they happen.

Why This Matters for Your Practice

The UK tax landscape is more complex than ever. Accounting software designed for UK businesses often includes features to calculate VAT automatically and submit returns directly to HMRC, ensuring full compliance with MTD regulations. Decision Trees take this a step further by ensuring the logic behind those calculations is transparent and verifiable.

Built by Accountants, for Accountants

We didn't just build Decision Trees in isolation. We worked closely with practicing UK accountants to understand the real challenges you face daily. Every question flow, every decision point, every outcome has been crafted based on actual scenarios from real practices. The result? A tool that feels natural, works intuitively, and delivers results you can trust.

The Decision Trees feature is live in Acting Office today. Whether you're handling Self Assessment queries, Corporation Tax complexities, or VAT determinations, you now have a powerful ally that ensures every decision is the right decision.

Log in today, explore your dashboard, and give it a try. It’s simple to use, yet powerful enough to change how you make accounting decisions — one smart branch at a time.

Getting Started is Simple:
