About this Product
Magento's native tax engine relies on manually maintained tax rates and rules, which collapses the moment you sell into thousands of US tax jurisdictions with shifting rates, special districts, and product-specific taxability. This extension replaces that with live Avalara AvaTax determination so the tax your customer sees at checkout is the tax you remit.
ECOSIRE builds this as a custom Magento 2 module under app/code/Ecosire/AvataxConnector, implementing Magento's tax service contracts and registering an interceptor (plugin) on the tax calculation flow so AvaTax rate calls run during quote totals collection. Calls are routed through Avalara's REST API using credentials stored via Magento's encrypted system configuration, with admin ACL gating access to settings and logs. Address validation runs at checkout and in the customer address book against Avalara's 13,000+ US jurisdiction database, normalizing addresses before tax is computed.
Exemption handling integrates Avalara CertCapture so tax-exempt customers and B2B accounts carry the right exemption codes. Product tax codes and nexus are configured per your catalog and where you have obligations, and committed transactions are pushed to AvaTax to feed automated returns filing (the filing itself remains in Avalara's platform — we wire the handoff, not the filing license).
Because every store differs — custom checkout, headless/GraphQL frontends, multi-store, multi-currency, Adobe Commerce B2B — this is scoped, built, and installed on your environment, not a one-click Marketplace download. You get clean, upgrade-safe code (DI, plugins, observers — no core hacks), a staging install, UAT against real orders, and production cutover. An active Avalara AvaTax subscription and API credentials are required.
What you get
- Custom Magento 2 module (app/code/Ecosire/AvataxConnector) with composer packaging, di.xml, ACL, system.xml config and database scripts as needed
- AvaTax integration wired into quote totals, invoice/credit-memo commit, and the customer/checkout address validation flow
- CertCapture exemption-certificate handling configured for your exempt and B2B customer groups
- Product tax code mapping and nexus configuration aligned to the jurisdictions where you collect
- Staging/UAT installation with a connection test and reconciliation of sample orders against AvaTax sandbox before go-live
- Production deployment, post-launch monitoring window, and technical documentation plus an admin handover walkthrough
Who this is for
US multi-state merchant with growing nexus
Sells across many states and special tax districts and can no longer maintain Magento native tax rates by hand. Needs rooftop-accurate, jurisdiction-correct tax at checkout and audit-ready records without manual rate uploads.
B2B / wholesale Adobe Commerce operator
Runs company accounts with tax-exempt resale and government buyers. Needs CertCapture exemption certificates honored at checkout so exempt orders calculate to zero and certificates stay on file for audit.
Finance / tax-compliance lead
Owns sales-tax accuracy and filings. Wants committed Magento transactions flowing into Avalara so returns filing is fed automatically, with logs and reconciliation that survive an auditor's questions.

Frequently Asked Questions about Avalara AvaTax Connector
Is this an instant download from the Adobe Commerce Marketplace?
No. This is a build-to-order engagement. ECOSIRE scopes the integration to your specific Magento 2 / Adobe Commerce environment (checkout, multi-store, headless/GraphQL, B2B), then builds, installs and configures the module on your store. You are not buying a generic zip to self-install — you are buying a working, installed integration.
How long until it's live on my store?
Typical delivery is about one working week after kickoff, depending on your checkout customizations, number of store views/nexus profiles, B2B requirements and access turnaround. We confirm a firm timeline during scoping. Work flows through a staging install and UAT before production cutover.
What ongoing support and updates are included?
The build includes a post-launch monitoring window and bug fixes for the delivered scope. Because the module uses dependency injection, plugins and observers — never core hacks — it stays upgrade-safe across Magento minor versions. Ongoing maintenance (Magento upgrade compatibility, Avalara API changes, enhancements) is available as a separate support arrangement; we'll quote it against your scope.
Do I need an Avalara subscription?
Yes. AvaTax determination, CertCapture and returns filing are Avalara services. You need an active Avalara AvaTax account with API credentials (account ID, license key, company code). This extension connects your Magento store to that account — it does not replace or include the Avalara subscription itself.
Does it work with headless / PWA Studio storefronts and Adobe Commerce B2B?
Yes, both are supported and scoped explicitly. For headless frontends we extend tax determination through GraphQL/REST so a custom or PWA Studio checkout gets the same AvaTax calculation as a Luma checkout. For Adobe Commerce B2B, company accounts, shared catalogs and exemption status are honored so exempt orders calculate correctly.
