Sales tax automation for US e-commerce; acquired by Stripe (2021) and integrated into Stripe Tax; previously served tens of thousands of merchants across all 50 states post-Wayfair ruling.
About
TaxJar is a Portland, Oregon-based sales tax automation platform that was acquired by Stripe in 2021 and subsequently integrated into Stripe Tax, Stripe's native sales tax and VAT calculation product. Founded in 2013, TaxJar built one of the most widely adopted sales tax compliance platforms for e-commerce businesses in the United States, automating the calculation, collection, reporting, and filing of sales tax across all 50 states. Before the Stripe acquisition, TaxJar served tens of thousands of online merchants, marketplaces, and SaaS companies that faced the complex and rapidly evolving U.S. sales tax landscape following the 2018 South Dakota v. Wayfair Supreme Court ruling, which enabled states to impose sales tax collection requirements on out-of-state sellers.\n\nTaxJar's pre-acquisition product addressed the fragmented state-by-state sales tax compliance problem comprehensively: it connected to e-commerce platforms including Shopify, WooCommerce, Magento, and Amazon, automatically calculating the correct sales tax rate for every transaction based on origin and destination addresses and product taxability rules. The platform aggregated sales data into state-by-state reports and automatically filed returns directly with state tax authorities, eliminating the manual monthly filing burden that required hours of staff time for merchants with sales in many states. Economic nexus threshold monitoring—tracking whether a merchant had crossed each state's revenue threshold triggering collection obligations—was a key capability given the rapidly changing post-Wayfair compliance landscape.\n\nFollowing the Stripe acquisition, TaxJar's technology forms the foundation of Stripe Tax, which provides real-time tax calculation embedded directly in Stripe's payment processing API. This integration means that any business accepting payments through Stripe can enable automatic sales tax, VAT, and GST calculation and collection without a separate tax software implementation. TaxJar continues as a brand for its AutoFile and reporting services for merchants on platforms outside the core Stripe ecosystem.

About
Billtrust is an accounts receivable automation and B2B payments company that provides a comprehensive order-to-cash platform for mid-market and enterprise businesses. Founded in 2001 and headquartered in Lawrenceville, New Jersey, Billtrust was acquired by FLEETCOR Technologies (now Corpay) to become part of one of the world's largest B2B payments businesses. Billtrust's platform covers the complete AR lifecycle from invoice delivery and customer payment portals through cash application, collections management, and credit decisioning, helping businesses accelerate cash flow and reduce the manual labor involved in managing large customer receivables portfolios.\n\nBilltrust's Business Payments Network (BPN) is a key differentiator, connecting AR teams with a network of buyer payment platforms and enabling electronic remittance matching that dramatically reduces the manual cash application work that burdens AR teams when customers pay by check or without detailed remittance information. The platform's AI-powered cash application engine automatically matches incoming payments to open invoices, handling complex scenarios like partial payments, short pays, and deductions, with automation rates that significantly reduce manual application work. Electronic invoice delivery, self-service customer portals, and automated collections workflows complete the AR automation suite.\n\nBilltrust competes with HighRadius, YayPay, Cforia, and the AR modules of large ERP systems, and has built particular strength in industries with high transaction volumes and complex payment scenarios including manufacturing, distribution, food and beverage, and wholesale. Its combination of AR automation software, B2B payment network capabilities, and now the scale of Corpay's payments infrastructure makes the combined entity a formidable competitor in the AR automation and B2B payments market.
