Ensure accurate and automatic tax rate calculation, on every sale
Tax rules and boundaries are constantly changing. Tax rates can differ depending on the business location, the type of product and final consumer location. Octobat best-of-breed geolocation system recognises customers location, and tax evidences in order to match these to the right tax jurisdiction – in more than 30 tax zones.
Deliver the right tax rate for every item sold - get fully compliant and trusted by your customers.
How it works
Octobat collects and stores three evidences: customer billing address, IP addresses, credit card or IBAN country code.
Octobat is able to differentiate between physical and digital goods and deliver the right tax rate in accordance with the local and international tax rules.
Tax calculation often depends on the nature of the customer receiving the product or service. A distinction must be made between a taxable customer (B2B) and a non-taxable person (B2C).
