What To Do Before You Start a Business Central Implementation

A Business Central implementation is easier to get right when your business is properly prepared before the project kicks off. How ready you are at the start has a direct bearing on how smoothly things run. These are the five things worth getting in order before a partner gets involved.

Know What Is Actually Broken

The most common mistake businesses make before an ERP project is defining requirements based on their current system. They document what they do now, rather than what they actually need. The result is a new system configured to replicate old problems rather than fix them.

Before you speak to anyone, have an honest internal conversation about where the real friction sits. Is it month-end taking too long? Reporting that requires manual assembly? Inventory data nobody trusts? Operations and finance working from different versions of the truth? Name the specific problems. That is the brief worth taking into a partner conversation, not a list of features you want to replicate from your existing setup.

Get Your Data in Order

Data quality is one of the most common causes of implementation delays and post-go-live problems, and it is almost entirely within your control before the project starts. If your current system contains duplicate records, inconsistent formatting, missing fields, or historical data nobody has cleaned in years, that mess does not stay behind when you migrate — it comes with you.

The work of reviewing, deduplicating, and standardising your data is unglamorous but critical. When International House London worked with TSG on their Business Central migration, data was reviewed and cleansed before a single record moved. The project was delivered on budget and to tight deadlines. Clean data coming in is one of the clearest predictors of a smooth go-live.

Map Your Integrations

Business Central will need to connect with other systems in your environment — whether that is a CRM, an e-commerce platform, payroll software, document capture tools, or bank feeds. The time to establish what those integrations are, and what they need to do, is before the project scoping conversation, not during it.

Integrations that are identified late tend to extend timelines and add cost. Those that are identified early can be designed into the project properly. Go through every system your business uses day to day and ask whether it will need to exchange data with Business Central. The answer is usually yes more often than people expect.

Secure Internal Sponsorship

Business Central is not an IT project. It affects finance, operations, sales, and management. Projects that are owned entirely by the IT team, without active involvement from the business functions that will actually use the system, routinely run into resistance at training and adoption stages.

The most successful implementations have a senior internal sponsor — typically a Finance Director or COO — who is involved from the start, can make decisions, and is visibly committed to the change. Their presence shapes how the rest of the business engages with the project. Without it, even a well-run technical implementation can stall at the point of adoption.

Set Realistic Expectations on Timeline

Business Central implementations take time. Discovery, configuration, data migration, integration work, testing, training, go-live, and the hypercare period that follows all need space in the plan. Businesses that go into a project expecting to be live in a few weeks, because someone suggested it was straightforward, often end up frustrated — not because the project is going badly, but because the expectation was never realistic.

A good implementation partner will give you an honest timeline based on your specific scope rather than an optimistic number to win the work. If the timeline you are being quoted feels too good to be true, it probably is. Ask how the figure was arrived at and what assumptions sit underneath it.
