Fixed assets in Business Central, in depth
By Emil Björk · Microsoft business apps consultant, Gothenburg
How Business Central tracks fixed assets — depreciation books, acquisition, disposal, write-down, and the link to FA insurance and maintenance.

The Fixed Assets module in Business Central is comprehensive enough for most small and mid-sized businesses, including organisations with multiple parallel depreciation requirements (e.g. local GAAP plus IFRS).
The asset card
Each fixed asset is a card with description, classification, location, responsible employee, vendor, and one or more attached depreciation books. Asset numbers can be generated via a number series or imposed from outside.
Depreciation books
A depreciation book holds the depreciation method, useful life, salvage value, and posting accounts for an asset. The same asset can be attached to multiple books in parallel — one for statutory accounts, one for tax, one for IFRS — each with different methods and lives. Books can be configured to post to the GL or to track values without posting.
Methods
Built-in methods include straight-line, declining-balance 1 and 2, DB1/SL combined, manual, and user-defined. Mid-month, full-month, and half-year conventions are supported. For specialist methods (units of production, double-declining variants), customers add an extension.
Acquisition
Assets are acquired through a fixed-asset journal, an FA G/L journal, or directly from a purchase invoice line where the line type is set to Fixed Asset. The integration with purchase invoices is the modern pattern — it captures vendor, vat, and the acquisition in one document.
Depreciation runs
The Calculate Depreciation batch job creates journal lines for the period; users review and post them. Depreciation is calculated to the day, so partial-period acquisitions and disposals work correctly.
Write-downs and appreciations
Asset values can be adjusted up or down through FA journals; the system posts the offsetting entry to user-defined accounts.
Disposal
Disposing an asset is a single journal entry with the proceeds amount; the system automatically posts the cost reversal, accumulated depreciation reversal, and gain or loss. Partial disposals and asset transfers between locations or departments are supported.
FA Insurance and Maintenance
Optional sub-modules track insurance policies and coverage values against assets, and record maintenance events and costs. Both are useful audit trails but neither replaces a CMMS for asset-heavy organisations.
Reporting
Standard FA reports cover register, additions, disposals, depreciation schedules, and book values; everything reconciles back to the GL via the FA posting groups.
