Exemption certificate / entity-use code handling mapped to BC customers and document lines

Multi-jurisdiction nexus and registration mapping covering US/Canada sales & use tax, EU/UK VAT and GST across 75+ countries

Bu Ürün Hakkında

This is a build-to-order Business Central extension, not an instant AppSource download. ECOSIRE builds it in AL, installs it as a per-tenant extension on your Business Central environment (SaaS Online or on-prem), and supports it after go-live.

The connector wires Avalara's AvaTax determination engine directly into the BC posting pipeline. Using AL event subscribers on the sales and purchase posting codeunits (OnBeforePostSalesDoc, OnAfterReleaseSalesDoc and related publishers), it intercepts documents before they post, builds an AvaTax CreateTransaction payload from the document lines, ship-from/ship-to addresses and tax codes, and writes the returned line-level tax back onto the document — so the GL, customer ledger and VAT entries reflect Avalara's real-time rate determination across 75+ countries (US/Canada sales & use tax, EU/UK VAT, GST and more).

We add table and page extensions for AvaTax tax codes, entity-use (exemption) codes and nexus/registration mapping, a setup page holding the AvaTax account ID, license key and company code (license stored via BC's isolated storage), and a permission set scoping who can post and reconcile tax. Address validation runs against Avalara's address API on customer/vendor cards. Calls are made through BC's HTTP client to the AvaTax REST endpoint, with a job queue entry for retry, batch commit (commit/void on posting and credit) and return-file data export.

Because it is your own per-tenant extension, the source is yours, it survives BC major upgrades (we recompile against each release), and there is no shared multi-tenant black box. You bring the Avalara account; we deliver the certified-pattern integration, deploy it, and validate it against real posting scenarios in a sandbox before production cutover.

Avalara-Certified Sales Tax & VAT Engine Connector for Business Central hakkında Sıkça Sorulan Sorular

Is this an instant AppSource download?

No. This is a build-to-order extension. ECOSIRE builds it in AL to fit your jurisdictions and tax-code mapping, then installs it as a per-tenant extension on your Business Central environment. You receive the full source code.

What is the delivery lead time?

Typical delivery is around 2 to 4 weeks depending on the number of jurisdictions, your exemption-certificate rules and how many document types need coverage. We start in a sandbox, validate against real posting scenarios, and only then cut over to production.

How does ongoing support and updates work?

Business Central ships major releases twice a year. We recompile and revalidate the extension against each release so it keeps working, and provide a post-go-live support window for fixes and configuration changes. Extended support and enhancement retainers are available.

Do I need my own Avalara AvaTax account?

Yes. You provide the AvaTax account ID, license key and company code from your own Avalara subscription. We securely store the credentials in BC isolated storage and wire the determination, commit/void and address-validation calls through to your account.

Will it work on Business Central SaaS (cloud) and on-premises?

Yes. The extension uses supported AL patterns — event subscribers, the HTTP client and the job queue — so it installs as a per-tenant extension on BC Online (SaaS) and on supported on-premises versions. We confirm your version and environment during scoping.
