Kintsugi is a next-generation sales tax compliance platform that applies AI to automate the determination, calculation, and filing process with less manual configuration than legacy solutions. Named after the Japanese art of repairing broken objects with gold, Kintsugi focuses on making sales tax compliance beautiful and low-friction for modern software companies that find existing tools cumbersome. The platform's AI engine handles economic nexus analysis across all 50 states, automatically registering for collection obligations as thresholds are crossed without requiring manual registration management. Product taxability determination uses AI to classify products and services against jurisdictional rules, reducing the manual configuration burden that makes Avalara and Vertex setup complex. Real-time sales tax calculation integrates with Stripe, Chargebee, Recurly, Zuora, and major billing platforms. AutoFile submits returns automatically in all required states, with Kintsugi handling the state DOR relationships. The compliance calendar provides forward-looking visibility into upcoming filing deadlines and payment due dates. Exemption certificate collection and management handles B2B customer exempt status documentation. The platform's modern API enables rapid integration for engineering teams at software companies. Kintsugi is positioned as the purpose-built sales tax solution for the modern software stack — less complex to implement than Avalara, more capable than manual approaches, and designed by a team that deeply understands the nexus complexity facing fast-growing SaaS and e-commerce companies.

Quaderno is a tax compliance platform built specifically for SaaS companies, digital product sellers, and subscription businesses that sell to customers globally and must navigate VAT, GST, and digital services tax obligations across dozens of countries. The platform's focus on digital goods and cross-border tax — an area where US sales tax platforms provide limited coverage — makes it the specialist choice for software companies managing European VAT, UK VAT, Australian GST, Canadian GST/HST, and the growing roster of countries implementing digital services tax on foreign sellers. Quaderno integrates directly with Stripe, Paddle, PayPal, FastSpring, Shopify, and WooCommerce to capture transaction data and calculate the correct tax amount in real time based on the buyer's location. Tax invoice generation creates compliant VAT invoices automatically, meeting the invoice content requirements of each jurisdiction. OSS (One Stop Shop) reporting handles the EU's simplified VAT filing mechanism for sellers below the EU registration threshold. Returns filing automation prepares and submits tax returns across jurisdictions where filing obligations exist. The customer dashboard provides a real-time view of global tax liability by jurisdiction, enabling better cash flow planning for quarterly and annual filings. Quaderno's specialist knowledge of digital goods taxability rules — where SaaS, apps, and digital downloads often face different tax treatment than physical goods — and its clean integration with developer-facing payment platforms make it the practical choice for digital-native businesses managing multi-jurisdiction tax.

LumaTax is a sales tax compliance platform positioned for small e-commerce businesses and marketplace sellers who need affordable, straightforward multi-state filing without the complexity or cost of enterprise solutions. The platform focuses on making sales tax returns accessible for sellers who have recently crossed nexus thresholds in multiple states and need to establish compliant filing without dedicating significant resources to tax operations. LumaTax imports transaction data from major e-commerce platforms including Amazon, Shopify, WooCommerce, and Etsy, automatically mapping sales to tax jurisdictions and preparing state return forms. The filing review interface presents prepared returns clearly before submission, allowing business owners to verify amounts before LumaTax files on their behalf. Economic nexus monitoring tracks sales against state thresholds and alerts businesses when new filing obligations arise. The free tier accommodates very early-stage sellers with limited multi-state exposure, while paid tiers unlock multi-state filing and higher transaction volumes at pricing well below Avalara and TaxJar. LumaTax lacks some enterprise features — real-time tax calculation for cart integration, exemption certificate management at scale, and complex product taxability configuration — but these limitations are largely irrelevant for its target market of individual sellers and early-stage e-commerce brands. For businesses with straightforward sales tax needs that balk at $99/month TaxJar pricing, LumaTax delivers the essential filing automation at a fraction of the cost.
