In their own words
AccurateTax
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.
AkuCalc
AkuCalc is an API product for calculating sales tax inside ERP, ecommerce, and billing workflows. It covers all US tax jurisdictions, including more than 13,000 jurisdictions, and supports Canada. Calculations use transaction addresses for rooftop-accurate results, while rates and rules update automatically as regulations change. Businesses can configure taxability by product, jurisdiction, and transaction type; complex or research-intensive mappings are scoped separately. A valid certificate stored in AkuCert is applied automatically as an exemption. The API connects custom ERP, ecommerce, billing, and other business systems, and featured integrations include Microsoft Dynamics 365, Business Central, Dynamics GP, Acumatica, Sage Intacct, QuickBooks, and NetSuite. Transaction data supports reporting, reconciliation, return preparation, and audit workflows. Clarus describes guided implementation covering configuration, integration setup, testing, and training, with timing depending on systems and data complexity. AkuCalc is aimed at finance, tax, controller, ERP, and growing-business teams. Pricing is on request through a custom quote.
