The Chart of Accounts (CoA) is the backbone of financial management in Business Central. Here’s how SMEs can use it to bring order to their finances, improve reporting, and support growth.
Chart of Accounts (CoA) in Business Central
When people hear “Chart of Accounts,” they usually think it’s an accounting term reserved for number-crunchers. But in reality, it’s one of the most important tools for keeping your finances under control in Microsoft Dynamics 365 Business Central.
To make it easier to get your head around, let’s explain it in two ways: first, the fun version, and then the proper version.
The Fun Version: Shelves for Your Money
Picture your business like that cupboard under the stairs. You know the one – where everything gets chucked: shoes, Christmas lights, old tools, even the dog’s squeaky toy that’s lost its squeak. Chaos.
Now, if you actually wanted to find something useful in there (say, a spanner), you’d have two choices:
-
Spend half an hour rummaging around, or
-
Put some shelves in and label them so you know where everything belongs.
That’s what the Chart of Accounts is. It’s the shelving system for your company’s “money cupboard.”
Every transaction – whether it’s a big sales order, the monthly warehouse rent, or the surprisingly high spend on office biscuits – gets its own labelled spot. Without it, you’ve basically got a shoebox of receipts and no clue where the money went. With it, you can say with confidence: £500 on biscuits, £10,000 on stock, £2,000 on rent.
Simple idea, massive impact.

The Proper Version: The Backbone of Your Finances
What is a Chart of Accounts?
A Chart of Accounts (CoA) is the structured list of all the accounts your business uses to record transactions – assets, liabilities, income, and expenses. It’s essentially the financial backbone of your system.
In Microsoft Dynamics 365 Business Central, the CoA underpins the finance module. Every account has a number and a name, making sure transactions are recorded in the right place and reports are consistent.
Why it matters
Without a well-structured CoA, financial reporting gets messy. With it, SMEs benefit from:
-
Clarity – you always know where costs and revenues belong.
-
Compliance – aligns with HMRC requirements and accounting standards.
-
Insight – allows for reliable reporting, budgeting, and forecasting.
How it works in Business Central
-
Account numbering: Ranges define categories (e.g., 1000–1999 for assets, 3000–3999 for income).
-
Posting groups: Automatically direct transactions to the right CoA account.
-
Dimensions: Add depth (like department or project) without creating endless new accounts.
-
Flexibility: Accounts can be blocked, reorganised, or added as the business grows.
Example in practice
Let’s say you’re a distribution business. Your CoA might look like this:
-
1000–1999 Assets: Cash, stock, vans.
-
2000–2999 Liabilities: Loans, suppliers.
-
3000–3999 Income: Sales (split into retail and wholesale).
-
4000–4999 Expenses: Rent, staff salaries, fuel, office supplies.
Post a fuel invoice, and Business Central ensures it lands in the right account. Next time you run your Profit & Loss report, you see exactly how much went on fuel, not just a vague “miscellaneous costs” bucket.
Best practices for SMEs
- Keep it simple – avoid creating too many accounts; use dimensions for detail.
- Plan for growth – leave gaps in your numbering for new accounts later.
- Work with your accountant – align the CoA with statutory reporting.
- Review regularly – update it as your business evolves.
Why SMEs should care
For companies upgrading from spreadsheets, Xero, or Sage 50, the CoA in Business Central is a game-changer. It’s the structure that makes real-time financial reporting possible, builds confidence in the numbers, and gives you the insight to grow.
In short: your Chart of Accounts is the framework that makes sense of the numbers. Without it, you’re just rummaging through receipts. With it, you’ve got order, clarity, and control.
What is a Chart of Accounts in Business Central?
The Chart of Accounts is the structured list of ledger accounts (assets, liabilities, income, expenses) used to record and report all transactions.
How should I structure my account numbers?
Use clear ranges (e.g., 1000–1999 assets, 2000–2999 liabilities, 3000–3999 income, 4000–4999 expenses) and leave gaps for future accounts.
What’s the difference between accounts and dimensions?
Accounts classify the type of transaction; dimensions add analysis (e.g., department, project) without creating more accounts.
Do posting groups affect the Chart of Accounts?
Yes. Posting groups route transactions to the correct accounts automatically, ensuring consistent postings and cleaner reports.
Can I change my CoA after go-live?
Yes, you can add, rename, or block accounts. Avoid changing numbers used historically; add new accounts instead to preserve reporting.
How often should an SME review the CoA?
At least annually, or when your product lines, legal entities, or reporting needs change.
