You started a business to sell a product, not to learn tax law in 50 states (or 100+ countries).
But once you cross state lines or hit certain revenue thresholds, sales tax stops being optional.
Here's what that process actually looks like when it's automated instead of manual:
β Connect and Monitor: Sync your billing, payment, HR, and ERP systems. Kintsugi tracks every transaction and alerts you the moment you cross an economic nexus threshold, or trigger physical nexus by hiring your first remote employee in a new state.
β Register and Collect: Register in the right jurisdictions, then apply precise, product-specific tax rules to every sale. No more guessing or applying a flat rate across the board.
β File and Remit: Returns get prepared, reconciled, and filed automatically, on schedule, without anyone logging into dozens of state portals every month.
One thing worth noting: AI handles the repetitive parts (nexus monitoring, classification, exposure tracking), but the actual tax calculations stay rules-based and deterministic, reviewed by our tax experts. Compliance needs auditable answers, not probabilistic ones.
