Avalara-style Marketplace Sales Tax Automation for Business Central

核心功能

Real-time sales tax calculation on sales order and posted invoice lines via AL event subscribers on the sales document lifecycle (OnAfterValidate / OnBeforePost)

Marketplace-facilitator handling that flags 'collected-by-marketplace' orders so tax is reported but not double-collected, driven by a marketplace channel field on the order

Multi-state US economic-nexus monitoring with configurable per-state revenue and transaction thresholds, with proximity alerts written to the BC job queue

Multi-country tax/VAT support that extends BC tax setup tables rather than overwriting native VAT posting groups

Exemption certificate management stored against the customer card via a table extension, with expiry dates and validity enforcement at calculation time

Automated returns-filing prep that aggregates seller-collected vs. facilitator-collected tax by jurisdiction and period into an exportable worksheet

Pluggable tax-rate sourcing: connect a third-party tax provider's REST API or use ECOSIRE-maintained internal rate tables, configured per environment

Dedicated tax-detail and audit tables so every calculation is traceable for accountants and auditors

BC REST/OData API endpoints exposed for external reconciliation and Power Platform / Dataverse reporting

Granular permission sets so finance, tax and admin roles see only the pages and actions they need

Delivered as a per-tenant extension (or packaged for your private AppSource pipeline) — no core object modifications

Job queue automation for nightly nexus recalculation, certificate-expiry sweeps and returns aggregation

关于此产品

If your business sells across multiple US states or countries through Amazon, Walmart, eBay, Shopify and other marketplaces, sales tax in stock Business Central quickly becomes unmanageable. Native BC posting groups and VAT/tax setup were never designed for economic-nexus thresholds, marketplace-facilitator "collected-by-marketplace" rules, or per-jurisdiction rate sourcing at order line level.

This is a build-to-order Business Central extension. ECOSIRE designs, builds, installs and supports it on your Business Central environment — there is no instant Microsoft AppSource download. We deliver it as a per-tenant extension (or, where you prefer, package it for your private AppSource pipeline), so the AL code, table/page extensions and permission sets live cleanly inside your tenant.

What it does. The extension adds real-time tax calculation to sales orders and posted documents via AL event subscribers on the sales document lifecycle, calling a tax-rate engine (your chosen provider's REST API, or our internal rate tables) and writing results back to dedicated tax-detail tables. A marketplace-facilitator layer flags orders where the marketplace already collected and remitted tax, so you report — but don't double-collect — correctly. A nexus monitor tracks economic-nexus thresholds per US state and raises alerts (via a job queue entry) as you approach registration triggers. Exemption certificates are stored against customers with expiry tracking, and a returns-prep module aggregates collected vs. facilitator-collected tax by jurisdiction for filing.

Everything integrates with the BC REST/OData API for external reconciliation, and can surface KPIs into Dataverse / Power BI. You get the source, the documentation, and a named ECOSIRE engineer for the build and rollout. Honest delivery: this is custom software, scoped to your jurisdictions and marketplaces, with a clear lead time below.

关于Avalara-style Marketplace Sales Tax Automation for Business Central的常见问题

Is this an instant AppSource download?

No. This is a build-to-order extension. ECOSIRE scopes it to your jurisdictions, marketplaces and tax-rate source, then builds it in AL and installs it as a per-tenant extension on your Business Central environment (sandbox first, then production). You receive the full source. We can package it for your own private AppSource pipeline if you prefer, but there is no public one-click install.

What is the delivery lead time?

Typical delivery is 3 to 5 weeks from scope sign-off, depending on the number of states/countries, whether you connect a third-party tax-rate API or use our internal rate tables, and your marketplace channel count. We start in your sandbox, validate calculations against sample orders with you, then deploy to production. We give you a firm timeline in writing after the scoping call — no surprises.

How do ongoing support and updates work?

The price includes a post-go-live support window with a named ECOSIRE engineer for bug fixes and configuration adjustments. Because tax rules, nexus thresholds and rates change, we offer an optional ongoing maintenance arrangement to keep rate tables, threshold values and facilitator rules current and to update the extension as Business Central evolves. You hold the source, so you are never locked in.

Will it break my existing VAT and tax setup in Business Central?

No. The extension uses table and page extensions plus event subscribers — it adds to native tax/VAT setup rather than overwriting it. Your existing VAT posting groups and posting setup keep working. New tax logic sits alongside them and is governed by dedicated permission sets, so you can roll it out to finance users gradually.

Can it feed Power BI or Dataverse for reporting?

Yes. We expose tax-detail and returns data through the Business Central REST/OData API, which Power BI and the wider Power Platform can consume. We can configure a Dataverse/Power BI reporting path during the build so your tax and nexus KPIs are available outside BC for dashboards and reconciliation.
