Uses AI agents instead of manual review

The Certificates agent scans submitted documents, prepopulates extracted certificate data, and verifies state tax IDs in real time, reducing manual validation, diminishing errors, and accelerating checkout without administrative delays.

Grounded in continuously updated tax rules

Backed by Avalara’s compliance content engine, ECM ensures every state form, exemption rule, and renewal schedule is continuously updated across thousands of jurisdictions, preventing uncollected tax liabilities across sales channels.

Provides audit-defensible visibility

Transform exemption management into a proactive risk-control function. ECM continuously flags missing, expired, or invalid certificates; traces correct documentation before filing deadlines; and preserves immutable audit trails to defend exempt sales.

HOW IT WORKS

4 steps to exemption certificate compliance

Connect

Add customers and certificates

Just tell Avi. Search for a customer, verify their exemption status, or create a new record through plain-language conversation. Directly link digital or scanned certificates to the customer record, and let our centralized repository and guided web portal keep your documentation organized, verified, and readily accessible at audit time.

Request

Request certificates automatically

The moment the Certificates agent identifies a missing or invalid certificate, just ask Avi to request one. The Certificates agent drafts and schedules customized customer outreach via email or our self-service portal, or seamlessly routes to physical fulfillment services on your behalf, tracking every touchpoint so you always know what’s outstanding.

Validate

Validate in real time

Upload a certificate in Aviator and the Certificates agent gets to work instantly to scan for missing or incomplete fields and extract key details like exemption reason, tax ID, and expiration date. Review the extracted data in a quick conversational check, and the agent categorizes the document status as complete, incomplete, or pending review.

Track

Track expirations proactively

Avi and the Certificates agent keep watch so your team doesn’t have to. Automated settings and reports flag expiring certificates early, while plain-language search lets you ask Avi about any customer’s exemption status in plain language, keeping your business continuously prepared for audits.

FAQ

ECM turns exemption management into a real-time, conversational risk control function. As certificates arrive, the Certificates agent, checks them against jurisdictional rules; extracts and verifies required fields; and flags expired, invalid, or missing certificates by customer, geography, or document type. Simply ask Avi in plain language which customers or regions need attention instead of digging through reports yourself. Built-in dashboards, configurable alerts, and proactive notifications let your tax team take action before issues surface during an audit, while audit-ready reporting generated upon request lets you quickly produce the documentation states ask for during sampling-based audits. 

When you cross an economic nexus threshold, you become responsible for either collecting tax or holding a valid exemption certificate for every previously untaxed sale in that state, often retroactively for the audit lookback period. ECM lets you launch automated multitouch outreach campaigns (via email, postal mail, and the Avalara Exemption Certificate Management portal) to back collect resale and exemption certificates at scale, route the right state form to each customer through Exemption Certificate Management, and validate submissions in real time. Exemption certificates and resale certificates are maintained together with their complete history, so when an auditor asks for years of documentation for a newly registered state, you can access it in minutes rather than months. 

Drop shipping is one of the most common audit triggers because the supplier, the seller, and the end customer can each be in a different state, and not every state accepts an out-of-state resale certificate from the seller. ECM gives you the complete library of state-accepted forms (including the Multistate Tax Commission Uniform Sales & Use Tax Resale Certificate, the Streamlined Sales Tax Exemption Certificate, and state-specific resale forms), guides each buyer to the correct form for the ship-to state, and tracks both home-state and ship-to-state requirements together. This way a buyer who only has a home-state resale document can be flagged for an additional document where the destination state requires it.

Expiration rules vary widely by state and by certificate type. Some states require annual renewal (e.g., Florida resale certificates and Alabama certificates of exemption), some have multiyear cycles (often three to 10 years), and some states keep certificates valid indefinitely as long as the underlying customer information stays accurate (e.g., California, New York, and Pennsylvania). Project-specific certificates expire when the project ends. ECM has state-specific expiration rules preconfigured, runs renewal reports, and triggers automated multitouch Exemption Certificate Management campaigns to your customers as certificates approach expiration. That removes the manual tracking burden and reduces the risk that you exempt tax on the basis of a certificate that expired months ago.

ECM is engineered to fit into existing finance landscapes without custom development. Avalara has more than 1,400 signed partner integrations across ERP (NetSuite, SAP, Microsoft, Oracle, Sage, QuickBooks), ecommerce (Shopify, BigCommerce, Adobe Commerce, WooCommerce), procurement, and POS platforms. ECM Pro and ECM Premium can run alongside Avalara AvaTax for end-to-end determination plus exemption, or as a standalone product alongside a third-party tax engine. A robust REST API and developer tools are available for custom integrations, including bulk certificate intake, customer sync, and certificate status queries.

With Avalara Aviator, Avalara ECM connects directly to Avalara AvaTax for determination and to Avalara Managed Returns for filing, so exemption decisions are reconciled inside the same workflow that calculates tax and prepares your returns. Through Aviator, Avi gives you one conversational layer across all three — ask Avi to verify a customer’s exemption status; request or validate a certificate; or check how an exemption flows into a return and it pulls from AvaTax, ECM, and Managed Returns together instead of making you jump between systems. Avalara Managed Services for ECM is also available if you’d rather outsource day-to-day certificate validation, outreach, and exception handling, with Avi supporting the team behind the scenes. The result is a single, audit-ready record of every exempt transaction, the certificate that supported it, and the return on which it was reported.
