System Selection for Accountancy Firms

Align your people systems after mergers and acquisitions

Growth through mergers and acquisitions can transform an accountancy firm overnight. But behind the growth, different practices bring different HR processes, payroll tools and recruitment workflows. We help you bring clarity to your people operations so your systems work as one organisation, not a collection of merged practices.

System Selection FAQs

Do we need to review our HR or payroll systems after a merger or acquisition?

If your firm has recently merged or expanded, it’s highly likely your current systems no longer reflect how your organisation operates.

We often see firms running multiple systems across offices, relying on spreadsheets or duplicating processes. A review helps you understand whether your current setup can scale or if consolidation is needed to support future growth.

We already have HR and payroll systems in place. Why would we revisit them?

Having systems in place doesn’t mean they are working effectively together. As firms grow, systems are often inherited from different practices and don’t integrate well. System selection isn’t about replacing technology unnecessarily. It’s about making sure your systems align with how your firm operates today and where it’s going next.

How do you handle complex partnership structures in accountancy firms?

We understand that accountancy firms often operate with a mix of partners, directors, qualified professionals, trainees and support teams.

During the discovery phase, we map how your workforce is structured, including partner remuneration, profit share and role variations. This ensures any system you select can handle the nuances of your organisation, not just standard employee models.

Can your approach work across multiple offices and regions?

Yes. In fact, that’s where our approach adds the most value. We help you define consistent processes across offices while still allowing for regional differences where needed. The goal is to create alignment without forcing a one-size-fits-all model.

Will this disrupt our day-to-day operations?

No. Our approach is designed to minimise disruption. We work alongside your team to gather requirements, review processes and guide decision-making without pulling people away from their day jobs unnecessarily.

The aim is to create clarity, not additional workload.

How does this help us as we continue to grow?

As your firm expands, complexity increases. The right systems help you integrate new teams more effectively, manage recruitment and onboarding at scale, and improve visibility across offices. In addition to supporting long-term growth without adding unnecessary admin
