Best for automated sales tax compliance

Best for automated sales tax compliance

If you're using Stripe, or a payment platform that is not a Merchant of Record (MOR), then you need to collect sales tax and VAT taxes, and remit payment, while registering the states/countries that you need hit your nexus in, meaning you are required to remit payment to them.

If all of this sounds overwhelming, it is. And that's where you need a sales tax platform like Numeral, who handles all of this for you automatically. If you've heard of Avalara, Numeral is a modern-day Avalara that doesn't suck.

What is Numeral?

What is Numeral?

Numeral is the modern sales tax platform for software companies, digital businesses, and ecommerce brands that want to stay compliant without hiring a tax expert. It handles aspet of compliance, from the nexus tracking to actually filing and remitting.

It's best for teams using Stripe, especially fast-growing startups, or digital product creators (you probably have no idea, but you should be collecting sales/VAT tax, and you aren't, and you will be liable for it in the future).

Not needed for Cash-only businesses that are local only, or those that are just using a Merchant of Record platform (MOR) like Polar, Paddle, or Gumroad.

Compared to Avalara or TaxJar, Numeral feels like the first sales tax tool that was actually built to be easy, out of the box.
