Numeral

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.

For high-income individuals and business owners

If you're a high net worth individual that has a startup and has complexity with investments (from angel investing to crypto and more), Gelt does a fantastic job at helping you reduce your tax burden, leveraging the best tax strategy.

What is Gelt?

What is Gelt?

We've switched business CPAs (Accountants) a handful of times over the past decade in business, as our personal and business needs have evolved over time.

Having tried everyone from the expensive big accounting firms, all the way down to the small boutique family offices, there has always been something missing.

Think of Gelt as the experience of the small boutique family office, with the experience of the big accounting firms (with the price somewhere in-between the two).

Gelt is a modern accounting firm that leverages modern software to do your business and personal taxes better.

They have a robust personal dashboard (similar to that of Compound), so you can aggregate all of your business and personal finances (even angel investment tracking), all in one place.

Their strategic help has easily saved us $20k in taxes, just on the advice we were given the first year. No other accountant has their own modern tech, nor have they been this helpful in actually working with the unique needs of our complex financial situation.
