See how TaxJar Plus simplifies sales tax
- Peak season traffic management. TaxJar can handle and scale with any increase (such as seasonality or special deals), in sales tax calculations/rate lookups or orders pushed into TaxJar.
- Dependable uptime and SmartCalcs response time. Our sales tax API clocks in at sub-75ms with 99.99% uptime; our calculations are more than 99.9% accurate and we offer an accuracy guarantee for all SmartCalcs users.
- Out-of-the-box eCommerce platform integrations. Your business is multi-channel, so your tax engine should be too. In addition to our API, TaxJar offers one-click integrations with NetSuite, Stripe, Magento, Shopify and more. Additional third-party integrations are also available and certified by TaxJar’s development team. All data is combined into a single, easy to use interface.
- Manage multiple users and permissions. The ability to add or remove multi-user access and manage permission levels for each member of your team is built right into TaxJar. Simply click, “invite new user” and you’re ready!
- Right rate, every time. ZIP code rates don’t provide the level of accuracy you need for accurate collection. With TaxJar Address Validation, you can rely on “rooftop-level” calculations to ensure that the exact address corresponds to the right rate.
