Case Study: Numeral streamlines sales tax automation and saves $200K annually with Rutter

How Numeral streamlined customer sales tax while saving $200K annually on engineering

Numeral, a financial services company, helps small and medium businesses automate sales tax collection and filing across multiple states and eCommerce channels. As Numeral scaled and added support for platforms like WooCommerce and eBay, its engineering team was stretched too thin by the complexity and maintenance required for new integrations.

To solve this, Numeral implemented Rutter’s universal API to connect with commerce platforms such as Shopify, Amazon, WooCommerce, eBay, Walmart, and Magento. With Rutter, Numeral sped up onboarding, shipped about five new integrations, saved more than 20 hours of engineering work each month, and reduced costs by roughly $180K–$200K annually.
