AccurateTax vs Avalara AvaTax

AccurateTax provides TaxTools, a cloud service for e-commerce sales-tax compliance. It calculates sales tax in real time from customer addresses, product taxability and applicable rules, while refining addresses to a US Postal Service-approved format. Reports let sellers file independently, or they can select services covering registration, filing and payment. Optional exemption-certificate management handles documents for exempt transactions. Integrations include Ability Commerce, Adobe Commerce, Magento Open Source, Miva Merchant, osCommerce, Shopify, ShopSite, Stone Edge Order Manager and WooCommerce. An XML API supports custom carts and other applications. AccurateTax identifies itself as a Streamlined Sales Tax Certified Service Provider and says free service is available under the SST contract where applicable. Pricing depends on processed orders and optional services, with charges per order rather than per API call. Basic Service lists 99.99% uptime.

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.

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.
