Business Central ships with a capable Fixed Assets module, but most asset accountants quickly hit its edges: reconciling a tax book against the book/IFRS view, applying jurisdiction-specific declining-balance and bonus-depreciation rules, and producing a clean tax-vs-book variance report that auditors will accept. This extension closes those gaps.

ECOSIRE builds Fixed Assets & Depreciation Management as a per-tenant AL extension installed directly onto your Business Central environment (cloud SaaS or on-prem). It extends the standard Fixed Asset, Depreciation Book, and FA Ledger Entry objects via table and page extensions — so your existing assets, posting groups and dimensions stay intact, and nothing is bolted on as a disconnected silo.

You get unlimited depreciation books running in parallel (book, tax, IFRS, group/management), automated depreciation runs scheduled through the BC Job Queue, and event-subscriber-driven journal posting that respects your G/L setup. Acquisitions, partial and full disposals, inter-location transfers, and component/group asset structures are handled with proper FA ledger entries and gain/loss calculation. Tax methods are parameterized per jurisdiction, and a dedicated tax-vs-book reporting page exposes per-asset and per-class variances, available over the BC OData/REST API for Power BI or Dataverse.

This is build-to-order, not an instant AppSource download. After purchase we scope your depreciation books, tax rules and report layouts, build the extension, install it as a per-tenant extension, validate against your real asset register, and hand over with documentation and a permission set. Honest lead time and ongoing support are described below. From $999 for the base build; complex multi-jurisdiction or multi-entity rollouts are quoted after scoping.
