Upgrading or replacing your accounting software is a big step - one that can unlock efficiency, better reporting, and improved compliance. But without the right approach, it’s also a step that comes with serious risks.
From mismanaged migrations to user resistance, poor planning can turn a well-intentioned upgrade into a costly disruption.
In this article, we’ll explore the four biggest risks of changing accounting systems and how to avoid them. We’ll also touch on common myths, the importance of future-proofing your solution, and how to tell when it’s time to say goodbye to legacy software.
One of the most common and costly mistakes finance teams make is diving into a system change without a clear vision. Without defined goals, it’s nearly impossible to align your implementation with business outcomes. Instead, you risk investing time and budget in features you don’t need, or worse - missing the ones you do.
A lack of clarity leads to:
Solution: Start with a goal-setting workshop involving key stakeholders. Define what success looks like - whether that’s faster month-end closes, automated reporting, or better integration with other systems.
Changing finance software is not just a technical upgrade—it’s a full-scale business transformation. Without a detailed project plan, you’re essentially flying blind. Delays, budget overruns, and confusion across departments become all too common.
The absence of a structured roadmap can result in:
Solution: A comprehensive project plan should outline the timeline, task owners, training requirements, contingency plans, and communication schedules. This ensures everyone stays aligned and the project stays on track.
Even with clear goals and a solid plan, the success of your system migration heavily depends on who’s leading the charge. An inexperienced project lead can underestimate the complexity, overlook compliance requirements, and fail to manage internal resistance.
Potential pitfalls include:
Solution: Appoint a project lead with proven experience in finance system migrations. Or get external project management.
Your new finance system is only as good as the data you feed into it. Poor data quality - duplicate entries, incomplete records, outdated supplier details - can result in reporting inaccuracies, compliance issues, and mistrust in the system.
Consequences include:
Solution: Before migration, conduct a thorough audit of your existing data. Cleanse, validate, and archive where necessary. Make data quality a central part of your implementation timeline.
Far too often, companies assume that switching accounting software is a quick fix. In reality, it’s a resource-intensive process requiring time, effort, and cross-departmental collaboration.
Underestimating this can lead to:
Solution: Budget for the real cost of change, including internal resource allocation, training, testing, and potential contingency time. Align your timelines to avoid falling on key financial reporting cycles to avoid peak pressure points.
Even the best accounting software can fail if your team doesn’t know how to use it. Training and change management are essential to get the most from your new system - and to avoid chaos post go-live.
Your finance team needs to be confident and competent with the new platform. Without that, mistakes creep in, workarounds emerge, and trust in the system quickly fades.
Effective training ensures:
Change management isn’t just about training. It’s about communication, leadership, and support.
Strong change management includes:
It’s natural to resist change, especially in a function as critical as finance. But involving your users early and addressing their concerns can significantly reduce friction.
Tactics that work:
It’s easy to choose a finance system that solves today’s problems - but what about tomorrow’s?
Many organisations pick accounting software that can’t scale with their growth, forcing another costly change just a few years later.
Risks of under-scaled systems include:
Solution: Choose a modern, scalable accounting platform that can adapt to your business over time. Cloud-based systems are particularly good at offering the flexibility and modular upgrades that growing businesses need.
There are plenty of myths around changing accounting systems - many of which stop organisations from making necessary upgrades. Let’s set the record straight.
Many finance leaders worry about losing access to historic records. The reality?
Most modern systems support full or partial data migration and compliant archiving.
You can:
Licensing costs for legacy systems can be high - but you don’t always need full access. Many businesses opt for read-only or archive solutions to retain access.
Ask your provider about:
Change doesn’t have to mean chaos. With careful planning and phased rollouts, businesses can keep disruption to a minimum.
Best practices include:
Actually, the opposite is usually true. Legacy systems often lack modern security features. New platforms typically include:
If you’re still using older systems like Sage 50, Microsoft Dynamics GP, or managing finances via spreadsheets, it may be time to explore modern alternatives. Outdated software can limit growth, introduce risk, and make life harder for your finance team.
Common red flags include:
Cloud-based platforms offer a host of benefits:
They’re designed to grow with your business - and keep your finance function agile, secure, and future-ready.
Changing your accounting software can transform your finance operations - but only if you approach it with the right strategy. By recognising the risks, planning ahead, and investing in training and support, you can make the transition smooth, efficient, and truly valuable for your business.
