For many UK SMEs, the transition to Microsoft Dynamics 365 Business Central is not just a software upgrade; it is a fundamental shift in how the business breathes. Whether you are moving from an ageing Sage 50 setup or a legacy ERP that has seen better decades, the success of your Microsoft Dynamics 365 Business Central implementation hinges on a single, pivotal role: the Functional Consultant.
But what exactly should you look for? For a business leader, an accountant, or a logistics manager, the technical jargon can often obscure the actual value. You don't just need someone who knows which buttons to click; you need a strategic partner who understands the British business landscape.
Here are 10 essential things UK SMEs must know when searching for a Business Central Functional Consultant.
1. The MB-800 Certification is the Baseline
In the world of Microsoft Dynamics, the MB-800 "Business Central Functional Consultant" certification is the gold standard for foundational knowledge. It proves that the consultant has been vetted by Microsoft on core application setup, from configuring companies to managing financial modules. While experience is king, this certification ensures your consultant is up to date with the latest cloud features and hasn't just brought "old" habits from the on-premise days of NAV.
2. Deep Finance Knowledge is Non-Negotiable

Business Central is, at its heart, a financial engine. A Business Central Functional Consultant in the UK must do more than just setup a General Ledger. They need to understand the nuances of UK accounting, VAT, partial VAT exemptions, and the requirements for Making Tax Digital (MTD).
If your consultant cannot talk comfortably about bank reconciliation or statutory reporting for UK entities, they aren't a functional consultant; they are a software administrator. For SMEs, where the FD often wears multiple hats, having a consultant who can double as a business process advisor is where the real ROI lies.
3. Strategic Solution Design Over "Out of the Box"
It is easy to turn on a cloud software package. It is difficult to weave that package into the specific fabric of your business. A top-tier consultant doesn't just ask "What do you want the system to do?" They ask "What business problem are we trying to solve?"
This is where the "Fractal IT Director" approach becomes vital. Strategic consultancy should always lead. The software is merely the tool to execute a broader business strategy. Look for a consultant who can map your current workflows and identify where they can be optimised, not just digitised.
4. Data Migration is a Specialist Art

One of the biggest hurdles in any Microsoft Dynamics 365 Business Central implementation is the data. Moving years of historical records from a legacy system is fraught with risk. Your consultant should have a robust methodology for data cleansing, mapping, and validation.
They should be proficient with configuration packages and Excel-based imports, ensuring that when you go live, your opening balances are correct, and your customer records are clean. "Garbage in, garbage out" is a cliché for a reason.
5. Mastery of the Power Platform and AI
Modern Dynamics 365 support for SMEs involves more than just the core ERP. We are now in the era of "Agentic AI" and the Power Platform. Your consultant should understand how to leverage Microsoft Copilot to automate mundane tasks and how to use Power BI to turn your data into actionable intelligence.
If they aren't talking to you about how Power Automate can handle your approval workflows or how AI can predict your inventory needs, you are missing out on the competitive edge that modern technology provides.
6. Understanding the "Bolt-on" Ecosystem
A specialist consultant knows that Business Central can't be everything to everyone. In the UK, SMEs often require specialized integrations, be it for freight and logistics, advanced print management, or VOIP integration.
Instead of trying to over-customise the core code (which makes future updates a nightmare), a savvy consultant will recommend "bolt-on" services. They treat traditional Managed Service Provider (MSP) services as execution layers that support the high-level strategy. This keeps your core system "clean" and scalable.
7. Training and Change Management

The best system in the world is useless if your staff hate using it. A functional consultant must be an educator. They should be able to explain complex processes in clear English to non-technical users.
UK SMEs typically have lean teams. Your consultant needs to provide tailored training that respects your employees' time and helps them see the personal benefit of the new system. Change management is often the difference between a successful implementation and an expensive failure.
8. Soft Skills and Local Context
Communication is often where projects stall. A Business Central Functional Consultant in the UK should understand the local business culture. This means being able to navigate the needs of a diverse range of stakeholders, from the warehouse floor to the boardroom.
Look for someone who is authoritative yet approachable. They should be able to manage expectations, say "no" when a request doesn't align with the long-term strategy, and provide the leadership necessary to keep the project on track.
9. Strategic Leadership: The Consultant as a Director

At Evestaff, we believe in a consultancy-first model. This means your functional consultant shouldn't just be an external vendor; they should act as your outsourced IT Director. They should look at your technology expense management (TEM) and ensure that every pound spent on licences and infrastructure is contributing to your bottom line.
Whether you are dealing with legacy systems like IBM i management or modern cloud infrastructure, the consultant’s role is to provide the high-level strategy that allows your business to scale without the friction of technical debt.
10. Practical Support and Post-Go-Live Care
The relationship shouldn't end the day you go live. Dynamics 365 support for SMEs requires an ongoing commitment. The business world changes, regulations evolve, and your system needs to keep pace.
A good consultant will ensure you have a support structure in place: not just for technical bugs, but for ongoing functional guidance. They should be your first call when you want to expand into a new territory or launch a new product line, ensuring your ERP is an enabler of growth, not a bottleneck.
Choosing the Right Partner
Finding the right Business Central Functional Consultant in the UK is about finding a balance between technical expertise and strategic vision. It is about choosing someone who understands that technology serves the business, not the other way around.
