Sphere is an API-based tax service for businesses handling sales tax, VAT, or GST.
What Sphere is
Sphere is an API-based tax service for businesses handling sales tax, VAT, or GST. Its API supports sales-tax calculation, tax registration, and automated return filing. The service is offered through API access rather than listed desktop or mobile platforms. The Starter plan costs $100 a month, billed monthly, for fewer than 10 regions. A Growth plan is listed for 10 or more regions, but its price is not provided. There is no free plan. Sphere therefore focuses on programmatic tax operations, covering calculation, registration, and filing within an integration. Businesses can use its listed tax types for transaction tax work and automated returns. Plan scope is tied to the number of regions, making regional coverage a key consideration when selecting between Starter and Growth.
