In their own words
Avalara AvaTax
Avalara AvaTax calculates tax in real time for sales and purchasing workflows. It covers sales tax, consumer use tax, VAT, communications tax, occupancy and lodging tax, and excise tax, and supports automated return filing and tax registration. Address validation uses geospatial technology to match transactions to tax regions rather than relying on ZIP codes. AvaTax connects with ecommerce, ERP, accounting, sales, and purchasing systems, and its REST API supports calculation, document modification, and address validation. Product taxability codes, AI-assisted item classification, custom rules, exemption certificate management, and jurisdiction-specific tax research support tax decisions. Reporting includes dashboards, natural-language search, and audit-ready trails. The service is available through web and API, with integrations including Shopify, NetSuite, QuickBooks, SAP, and Salesforce. Core Compliance costs $79 per month; Core Compliance + SST Services costs $69 per month for qualifying sellers. Qualified sellers may receive state-funded services in up to 25 states. Pricing also varies by plan and transaction volume.
