Our verdict on Clarus
Clarus is sales tax compliance software for finance and tax teams managing multi-state operations. Its product lineup covers AkuCalc for sales tax calculation, AkuCert for exemption certificate management, AkuLicense for business license management, and Managed Returns Filing supported by Clarus tax professionals. The product is suited to small and mid-market manufacturers, distributors, wholesalers, and other businesses handling recurring sales-tax obligations across multiple jurisdictions. Its API-based approach makes it a fit for organizations that want to connect tax workflows with existing operational systems rather than manage sales tax as a standalone desktop process.
The product’s strongest area is breadth within sales-tax compliance. AkuCalc provides calculation across 13,000+ U.S. jurisdictions, with real-time tax rates and rule updates and configurable product taxability rules. AkuCert supports exemption certificate collection, validation, storage, and renewal tracking, while AkuLicense provides business license tracking and renewal workflows. Managed Sales Tax Return Filing adds assisted preparation and filing, extending Clarus beyond calculation into recurring compliance work. Together, these tools address calculation, documentation, licensing, and returns in one sales-tax-focused product family.
Platform fit is another important consideration. Clarus supports API integrations and connects with NetSuite, Sage Intacct, Microsoft Dynamics 365, Business Central, Epicor, QuickBooks, SAP, Salesforce, BigCommerce, and WooCommerce, along with custom integrations. The published pricing approach is contact-sales: AkuCalc pricing varies by business structure, transaction volume, and integration needs, with a customized quote. Clarus should appeal to businesses that need API-led sales-tax workflows and assisted filing; organizations seeking tax types beyond sales tax or a primarily nontechnical workflow should consider a broader or differently oriented alternative.
