Selling at the right tax rate made simple

No more headaches with tax rates! Octobat sales tax calculation ensures a full rate monitoring for your business and allows you to sell at the right tax for every transaction.

The complexity of local and international sales tax laws is based on international legislation (VAT MOSS, local VAT, GST, sales tax...), type of buyer (end-consumer or business) and category of product (physical, e-books, digital goods).

Octobat synchronizes your payment data, retrieving it from your payment provider or in real time at checkout, allowing for tax exclusive/inclusive pricing models - all ensuring you always apply the right tax rate.
