Business Central Finance Implementation: Process, Costs and Benefits for UK Businesses

A finance team can spend much time verifying work that has already been done. Someone records a supplier invoice in the system, but another person still needs to check the amount against the purchase order. A bank payment comes through, and nobody is quite sure which invoice it belongs to. Then month-end arrives, and the team is back in Excel, trying to match the figures.

This is one reason UK businesses look at Microsoft Dynamics 365 Business Central. They want their accounts in better shape and less time wasted moving information between systems.

Moving to a new system takes some planning, though. The old account codes might not fit the new setup. Customer balances need to be checked against the existing records. Reports that worked in the previous system also need testing to make sure they produce the expected figures in Business Central.

Getting these details right is a key part of a Business Central finance implementation. The software is only part of the job.

What does Business Central cover?

Business Central covers the general ledger, supplier invoices, customer payments, bank reconciliation and financial reporting. It also links finance to purchasing, sales and inventory, which matters more than it sounds.

Take a purchase invoice for stock. It changes the supplier balance. It carries VAT, and it adds to stock value or lands in an expense account. With separate systems, someone checks each of those manually. In Business Central, the entries are posted together when the system is set up correctly.

Dimensions handle the breakdowns. Instead of opening a separate ledger account for every department and project, the business tags each transaction with a department or project code. A wholesaler wants warehouse costs. A consultancy wants fees by project. Same software, different setup.

How should you set up the chart of accounts and dimensions?

Copying the old account list is the quick option. It also copies the issues: duplicate codes, accounts nobody has posted to since 2019, and three separate accounts that exist only because the old system couldn’t split costs by department.

Start with the reports. If finance splits costs by department in Excel every month, that split belongs in dimensions, not in the chart of accounts. Ask the person who prepares the monthly accounts what management needs to see, then build the setup around those requirements.

Posting groups need the same care. They determine which general ledger accounts are used for a transaction. If one is configured incorrectly, the invoice might look fine on screen while the entries go to the wrong accounts. The problem may not surface until someone checks the trial balance.

Set up the dimensions before the team starts recording live transactions. If different people use different department codes for the same costs, the reports will be inconsistent. Sorting out those differences later means going back through earlier transactions and correcting the records.

How are invoices, payments and awkward cases handled?

A supplier invoice arrives without a purchase order. A customer pays five invoices in one bank transfer. Another invoice is disputed. These situations need attention because they can hold up routine finance work.

Before go-live, walk the finance team through each case and agree who is responsible. Who approves an invoice without a purchase order? How should a disputed amount be handled while the issue is being resolved? Who follows up overdue balances, and when? If approvals currently happen over email, decide whether to keep that process or move it into Business Central.

Business Central provides tools for managing payables and receivables, but the team still needs clear rules to follow. Without them, staff can end up relying on the same spreadsheets and email reminders the new system was meant to replace.

How do you move finance data into Business Central?

Moving to Business Central involves transferring financial records while the team continues its work. These include customer and supplier records, opening balances, unpaid invoices and bank balances. Old transactions need a separate decision. If they stay in the old system, finance staff must still be able to access the records they need.

Then check the numbers. Say the old system shows £42,000 in outstanding customer invoices, but Business Central shows £39,500 after the import. The import finished without an error, yet there is a £2,500 difference. Someone needs to find out why this is happening before the team can rely on the new balances.

Run the same checks on supplier accounts, bank balances and the trial balance. Clean up duplicate customer records and incomplete supplier details at the same time. Allow time for this work in the project plan rather than leaving it until the last week.

The timeline depends on the quality of the existing data, the number of companies involved and any work needed on reports or integrations. The plan should also allow time for testing, training and sign-off. Agree these steps with your implementation partner before setting the go-live date.

How do you set up VAT, bank reconciliation and reports?

VAT settings need to match the way the business operates. Business Central uses VAT posting groups and related settings to calculate and post VAT. The finance lead or accountant should check these settings against actual transactions, including zero-rated and exempt sales where applicable, before approving the setup.

Bank reconciliation needs testing too. Use real bank statements and check a routine payment, an unmatched entry and a transaction that needs investigating. Staff should know how to handle a payment that doesn’t match before the first live month, not while they’re trying to close the accounts.

For reports, compare the profit and loss account and balance sheet in Business Central with the figures from the old system. If management needs costs broken down by department or project, check those reports as well.

Before go-live, ask a finance user to prepare a month-end report without help from the implementation team. If they still need to export figures to Excel and correct them manually, find out why. The report might be using the wrong setup, or the team might need more training.

How much does a Business Central finance implementation cost?

The cost has two parts: licences and the work to implement the system.

Business Central licence types

Microsoft's published UK prices are per user per month, billed annually and excluding VAT. These are licence costs only, not implementation fees. Check the Business central pricing before budgeting, as prices can change.

For example, five Essentials users would cost £307.50 per month, or £3,690 a year, before VAT. The actual licence mix depends on what each person needs to do in Business Central.

A finance project doesn’t need Premium by default. Choose it only if the business plans to use manufacturing or service management in the same system.

What affects the implementation fee?

One business has a single company, tidy records and standard reports. Another has several legal entities, multiple currencies, a payroll link and years of messy history. They are different projects with different quotes.

When comparing quotes, read what each one includes. One partner includes data cleansing and training. Another expects your team to do both. The totals look alike, but the work behind them doesn’t.

Ask how extra requirements are priced, too. If testing turns up a missing report or a data problem, you need to know how that could affect the budget and timeline before the work begins.

What should improve once Business Central is live?

The first change shows up in the weekly jobs. Bank reconciliation is the obvious one. Staff who match every payment by hand can let Business Central match bank entries against transactions already in the system. A payment with no clear reference still needs a person, but not every line does.

Overdue invoices come next. A finance manager shouldn’t have to open three spreadsheets to see who still owes money. Business Central keeps customer entries and receipts together, so chasing starts from one list.

Reports are different. The software can’t repair a chart of accounts that was planned badly. If management wants warehouse costs separate from sales expenses, that has to be built in during configuration, or someone is back in Excel every month.

Finally, tracing gets easier. When a supplier invoice is questioned, the team follows the linked entries instead of piecing the story together from separate records. How much time that saves depends on how well the setup was tested.

Should you choose Business Central or Dynamics 365 Finance?

Business Central suits small and medium-sized businesses that want finance and day-to-day operations in one system. Dynamics 365 Finance is built for more complex enterprise financial requirements.

Headcount doesn’t settle it. A company with 80 staff and six legal entities can have more complex financial requirements than one with 300 staff and a single ledger. Compare the legal structure, reporting needs, financial controls and integrations before choosing. The decision should reflect the processes the business needs to manage, not employee numbers alone.

How do you choose a Business Central implementation partner in the UK?

A good demo shows what the software can do. But it doesn’t tell you how a partner will handle your finance data or what happens when something goes wrong during implementation.

Ask how they’ll deal with your existing chart of accounts, check opening balances and fix data that doesn’t match. Find out what your finance team will need to do and who will help when you reach your first month-end close.

Check the quote too. Does it cover data migration, training and support after go-live? What happens if extra work comes up? A cheaper quote isn’t always the better option if it leaves your team to sort out the difficult parts.

How can Dynamics Square help with your finance implementation?

Dynamics Square works with UK businesses on Microsoft Dynamics 365 projects, including Business Central implementations.

Start with the issues your finance team deals with every day. Maybe reports take too long to prepare, or staff still copy figures from one system to another. These are the things worth sorting out during implementation.

Before speaking to Dynamics Square, take a supplier invoice and follow it from entry to payment. See where manual checks are needed and where things get held up. This gives you a clearer idea of what needs to change.

Getting the setup right from the start makes a difference. Your team should spend less time fixing figures and more time getting on with its work. Contact us Today!
