Sphere

Sphere is a tax compliance platform that automates cross border indirect tax for companies selling into many countries. It determines the correct VAT, GST or sales tax at the point of sale, then handles registration, filing and remittance with each local authority on its own schedule, covering more than 130 jurisdictions without country by country setup or local accountants. The company describes it as an AI native tax engine: its research model, TRAM, reads tax law and rulings, tax experts approve each determination, and a deterministic engine applies the result in real time with a full audit trail. It is built for finance teams at global businesses, for billing and commerce platforms that need compliant tax logic inside checkout, and for accounting and tax advisory firms filing on behalf of clients. Beyond the core Indirect Tax Platform, an Input Tax product pulls recoverable VAT, GST and use tax out of accounts payable and expense data and applies each jurisdiction's deductibility rules, and an electronic invoicing product issues invoices in each country's mandated format and clears them through the required reporting channel. Customs and withholding tax products are announced for 2027. Sphere connects to existing billing and finance tools including Stripe, Xero, NetSuite and QuickBooks. Pricing is a flat rate per region per month with no implementation fees. Starter is $100 per region per month for fewer than ten regions and includes monitoring, registration, calculation for up to 50,000 transactions, filing and remittance, and the local rails and integrations. Growth is custom priced for ten or more regions and adds a dedicated account manager, a tax team on demand, Slack support around the clock and back tax calculations. Input Tax and electronic invoicing are add ons priced on request.
