Using Cost Centre Accounting

This guide explains how to use cost centres in SimplBooks and how to generate cost centre-specific reports.

What does cost centre accounting mean?
Cost centre accounting, also known as project accounting, allows you to track the income and expenses of a specific cost centre. It enables you to compare different projects with each other, for example.

When should cost centres be used?
Cost centres are useful when you want to track the finances of different parts of your business separately. They are particularly helpful for businesses with multiple lines of business or trade names whose activities you want to analyse independently. Cost centres are also well-suited to project-based operations, such as the construction industry, when you want to track the income and expenses of different projects separately.

How are cost centres organised in SimplBooks?
In SimplBooks, cost centres can be created at two levels: as main cost centres and sub-cost centres. See the guide for adding cost centres here.

Cost centre-specific reports

The software has a dedicated cost centre report, and you can also filter by cost centre in reports such as the income statement and balance sheet.

1. You can access the cost centre report from Reports > Cost Centre Report.

2. Select the desired time period and cost centre.

  • You can search for a cost centre by part of its code or name.
  • Once you have selected the time period and cost centre, click “Generate“.

3. The report shows the income and expenses allocated to the selected cost centre.

  • The Summary tab shows an overview of all cost centres. If no cost centre has been added to an income or expense item, it will appear with the label “Unassigned”.
📢 Note! The cost centre report shows data from purchase and sales invoices as well as receipts and payments. If you use only the accounting module without invoices, the software will only provide cost centre-specific accounting reports, such as the income statement, balance sheet, general journal and general ledger. Accounting journal entries alone do not appear in the cost centre report.

4. In other reports, the cost centre filter can be found in the Filters section of the report page.

  • The cost centre filter is available in most reports.
