AI-native indirect tax engine automating registration, calculation, filing, and remittance across 100+ regions.
Sphere is an indirect tax platform that automates the full sales tax and VAT lifecycle for software and digital businesses — monitoring where you owe tax, registering in those jurisdictions, calculating tax on transactions, and filing and remitting returns. It pitches an AI-native, hands-off operation aimed at SaaS and AI companies selling globally with small finance teams. In the revenue stack it plugs into billing and payments flows at the tax-setup and calculation layer, then carries the obligation through to filed returns.

Sphere's angle is end-to-end ownership with minimal operator effort: rather than selling a calculation API and leaving registrations and filings to you or a separate service, it bundles nexus monitoring, registration, calculation, and remittance into one managed motion. For lean teams, tax compliance becomes something the vendor runs rather than a workflow the team operates.
The category is the same — indirect tax compliance — but Sphere leans into a managed, AI-driven operating model targeted at digital-first companies, bundling the registration and filing work that classic engines often treat as add-ons. Established vendors counter with breadth, track record, and deeper enterprise integrations.
Earlier than most do. US economic-nexus thresholds and international digital-services rules can create obligations from remote sales alone, and back taxes accrue whether or not you collected them from customers. Monitoring exposure before crossing thresholds is much cheaper than remediating afterward.
