Microsoft Dynamics 365 Business Central ships solid native tax setup — Tax Groups, Tax Areas, VAT Posting Groups and VAT Business/Product Posting Group combinations — but it expects you to maintain every rate, every jurisdiction boundary and every exemption rule by hand. As soon as you sell across US states, EU member states, the UK, the GCC or APAC GST regimes, that manual matrix becomes a compliance liability.
Real-time tax rate lookup on sales and purchase lines via AL event subscribers (OnAfterValidateEvent on Sales/Purchase Line, posting OnBefore events) calling your connected tax-content gateway
US sales tax determination across state, county, city and special district levels plus global VAT and APAC/GCC GST coverage
Address cleansing and automatic jurisdiction assignment from ship-to / ship-from, with normalized addresses written back to the document
Product tax category mapping and exemption-certificate storage with per-customer, per-jurisdiction validity dates
Nexus and economic-threshold monitoring with a dashboard cue and notifications as registration thresholds approach in each jurisdiction
Native table and page extensions over Sales Line, Purchase Line, Customer and Item — no replacement of BC's native posting engine
This is a build-to-order AL extension that brings Avalara-style automated tax determination directly into Business Central. ECOSIRE designs, builds, installs and supports it on your tenant — it is not an instant Microsoft AppSource download. We scope your jurisdictions and connected tax-content provider, develop the extension, deploy it as a per-tenant extension (or submit through AppSource if you require it), then support and update it.
The engine subscribes to standard sales and purchase document events (table and page extensions over Sales Line, Purchase Line, and the posting routines via OnAfterValidateEvent and posting OnBefore event subscribers). On line entry it calls your tax-content gateway, resolves the correct jurisdiction from a cleansed ship-to/ship-from address, applies the right rate and exemption logic, and writes the result back to the document and the posted VAT/tax entries — no rip-and-replace of native posting.
Address validation, product tax categories, exemption-certificate storage, and nexus/threshold tracking are all surfaced on native-feeling pages with their own permission sets. Tax calls run inline for accuracy and can be batched via the Job Queue for high-volume documents. Because it's your tenant's own extension, you keep full control, an audit trail, and a documented upgrade path across BC monthly releases.
Owns indirect-tax compliance across many jurisdictions and is tired of hand-maintaining BC Tax Areas, VAT Posting Group matrices and rate tables. Needs automated, audit-ready determination and early warning before nexus thresholds trigger new registrations.
Responsible for correct VAT/tax entries, statutory reporting and clean month-end. Wants tax automation that augments native BC posting rather than replacing it, with a documented upgrade path across monthly releases.
Manages the BC tenant, extensions and integrations. Cares about per-tenant extension governance, permission sets, the REST/OData and Dataverse surface, telemetry, and a supported, source-available solution they can maintain.

No. This is a build-to-order AL extension. ECOSIRE scopes, builds, installs and supports it on your own Business Central tenant as a per-tenant extension. We can submit it through AppSource on request, but there is no instant self-service download — the price reflects a custom build delivered to your environment.
A typical single-country or single-region build is delivered in roughly 2 to 4 weeks after we confirm your jurisdictions, tax-content gateway and BC version. Multi-region footprints, AppSource submission or heavy Power Platform integration extend that. We give you a firm timeline after a short scoping call before any work starts.
After go-live you get a defined support window covering bug fixes, configuration help and compatibility with Business Central's monthly releases. We hand over the source code and a runbook so your team is never locked out, and we offer renewable support plans for tenants that want ECOSIRE to own the upgrade path long-term.
The engine resolves rates and jurisdictions through a tax-content gateway, and that provider account is yours. We integrate the extension against your chosen provider (or against a rate dataset you supply) — the build covers the AL engine, address logic, exemption handling and BC integration, not the third-party content subscription.
No. The engine uses table/page extensions and event subscribers over Sales Line, Purchase Line and the posting routines, then writes calculated tax back into the standard VAT/tax entries. Native posting, statutory VAT reports and the audit trail keep working, and it falls back to your native Tax Areas if the gateway is unreachable.
