Numeral’s API can be integrated with your website to ensure compliant and accurate tax collection from your customers at time of checkout.

At a high level, our API is used to calculate tax rates. You’ll give us an address and a set of products, and we’ll return the accurate tax amount you should charge. After your sale clears, you’ll log the transaction with us so we can file your tax return.

Beyond that core functionality, we help you manage your products’ tax categories, account for refunds, and manage your exempt customers.
