About this Product
Microsoft Dynamics 365 Business Central ships with a capable but deliberately simple VAT/tax-posting-group model. For companies trading across many jurisdictions, that model breaks down: nexus-driven use tax, excise duties, product- and customer-specific taxability, and per-line origin/destination logic are not something the native posting groups were built to express.
Vertex-Style Enterprise Indirect Tax Determination is a per-tenant AL extension that ECOSIRE builds, installs and supports directly on your Business Central environment (Online or on-prem). It is not an instant AppSource download — it is engineered to your jurisdictions, products and integration target, then deployed as a private extension scoped to your tenant.
The extension layers a determination engine over native posting: AL event subscribers on sales, purchase and journal documents (OnAfterValidate, OnBeforePostDocument) intercept each line, resolve the correct jurisdiction stack via a configurable product taxability matrix, and either calculate rates in-engine or call an external O-Series-style cloud rate service over the BC REST/OData layer. Determination results write back to native VAT entries so standard reporting, VAT statements and audit trails remain intact.
Table and page extensions add the taxability matrix, jurisdiction registers, use/excise rules and per-line determination detail. Dedicated permission sets, a job-queue retry path for high-volume batch posting, and Dataverse-friendly API pages round out the build. ECOSIRE delivers source, documentation, a deployed extension and a support window — you own a tax engine fitted to your business, not a one-size-fits-all listing.
What you get
- A per-tenant AL extension (.app) built for your jurisdictions and installed on your Business Central environment (Online or on-prem)
- Complete AL source code: table/page extensions, codeunits, event subscribers, permission sets and API pages
- Configured product taxability matrix and jurisdiction registers seeded with your tax treatments
- Integration to your chosen O-Series-style cloud rate engine, or a maintained in-engine rate table if no external service is used
- Job-queue setup for high-volume batch determination plus retry handling for external lookup failures
- Technical and admin documentation: configuration guide, permission-set map, and rate-engine connection runbook
- Deployment to sandbox first, validation against sample transactions, then promotion to production
- A defined post-launch support window with bug fixes and a BC monthly/major-release compatibility check
Who this is for
Multi-jurisdiction Finance Controller
Owns VAT/GST/use-tax accuracy across several countries or US states and needs determination that native posting groups can't express, without losing standard BC reporting.
BC Solution Architect / IT Lead
Wants tax logic delivered as a clean per-tenant extension with source, permission sets and API pages — not unmanaged customizations baked into the base app.
Tax & Compliance Manager
Needs a defensible audit trail per line, exemption-certificate and reverse-charge handling, and a documented rate source for every transaction.

Frequently Asked Questions about Vertex-Style Enterprise Indirect Tax Determination for Business Central
How long does delivery take, and is this an AppSource app I download?
No — this is build-to-order. ECOSIRE engineers the extension to your jurisdictions, products and rate-engine target, then installs it as a private per-tenant extension on your Business Central environment. There is no instant AppSource download. Typical delivery is roughly one working week depending on the number of jurisdictions, whether you connect an external cloud rate engine, and the complexity of your taxability matrix. We deploy to a sandbox first, validate against your sample transactions, then promote to production.
What ongoing support and updates are included?
The one-time build includes a defined post-launch support window covering bug fixes and a compatibility check against Business Central's monthly and major releases, since base-app changes can affect event subscribers and API pages. Rate-table maintenance, new jurisdictions, or new integrations after the window are handled under a separate support agreement. Because you receive the full AL source, you are never locked out of your own extension.
Will this break native VAT/GST reporting or the audit trail?
No. The engine augments rather than replaces native posting. Event subscribers resolve the correct treatment per line and write results back to standard VAT entries, so VAT statements, audit reports and the GL stay authoritative. Each determination is logged with jurisdiction, rate, source and timestamp for traceability.
Can it call an external cloud tax engine, or does it calculate rates itself?
Both are supported. It can integrate an O-Series-style cloud rate engine over the BC REST/OData API for live, maintained rates, and it keeps an in-engine fallback rate table. A job-queue retry path handles transient external-lookup failures so high-volume posting isn't blocked by a slow or unavailable rate service.
Does it work with Power BI and the Power Platform?
Yes. The build includes API pages and Dataverse-friendly exposure so per-line determination data can feed Power BI tax dashboards or Power Automate flows. Dedicated permission sets keep configuration, override and read-only review access separated for governance.
