Sphere
ActiveAI-powered sales tax, VAT and GST compliance
About
Sphere is an AI-powered cross-border compliance platform. We help companies like Lovable, Eleven Labs, Replit and Windsurf automate their sales tax, VAT, GST compliance obligations. What makes us different to other vendors on the market is: 1. we have spent the last 1.5 years building local rails into 100+ tax authorities in both the US and internationally to properly automate compliance processes, and 2. we've built the world's first AI-native tax engine which ingests, codifies and monitors tax law globally.
Sphere provides AI-native end-to-end tax compliance automation for sales tax, VAT, and GST with a global coverage across 100+ tax authorities. It combines an AI Tax Engine and a Tax Review model to automate registration, calculation, filing, and remittance, integrated with major billing stacks and supported by 24/7 expert assistance.
Sphere delivers end-to-end indirect tax automation through a globally connected infrastructure (local rails) that registers, calculates, files, and remits taxes for 100+ jurisdictions. It uses an AI-native Tax Engine to calculate taxes and a Tax Review and Assessment Model trained on real tax code to monitor laws and rates, automating research and coverage. The platform integrates with billing systems, monitors for registration needs, simplifies multi-jurisdiction registrations, and handles government portals and submissions. It supports real-time tax coverage, cross-border compliance, and 24/7 Slack-based tax expert support.
