Brex's website

Since its launch in 2018, Brex has transformed from a company offering corporate credit cards for startups to a company offering comprehensive financial solutions for modern businesses of all sizes. More than 35,000 businesses, including more than 150 publicly traded companies, in more than 120 countries trust Brex to power key parts of their financial infrastructure. Brex offers a wide range of services, including corporate cards with built-in controls and credit limits up to 40 times higher than those offered by traditional banks. In addition to credit cards, Brex offers business bank accounts with impressive interest rates and AI-powered vendor payments, automated expense reports, and AI-driven accounting support. It has also built a proprietary software and payment infrastructure.

Brex’s automation tools save companies an average of 4,250 hours per year, but the company was still facing a major accounting challenge of its own: sales tax compliance.

Why Brex needed support for sales tax compliance

Brex is growing quickly; it increased revenue by 80% year-over-year in 2025. And it has become a global solution, expanding into new regions and serving many large and fast-growing enterprises.

While rapid scaling is generally a good thing, it also introduces significant challenges related to complying with sales tax, VAT, and GST regulations. Brex must ensure that it:

• Tracks nexus to understand its sales tax, VAT, and GST obligations. In the United States, a company becomes responsible for registering with a state and collecting sales tax if it establishes a physical presence there, or if its sales revenue or number of sales reaches a certain threshold.
• Registers when required: Once a business has established nexus in a jurisdiction, it is required to register with local tax authorities.
• Collects the correct sales tax. Brex offers its customers a variety of products and services, including business banking services and expense management software.
• Files and remits sales tax, VAT, or GST. Depending on the volume and/or number of sales in a location, Brex may be required to file and remit sales tax returns and payments there.
• Complies with local rules and requirements. With customers in more than 120 countries, Brex must know and comply with many different rules.
• Remains audit-ready. This means keeping detailed accounting records, ensuring that the correct tax amounts are collected on products that may be taxed differently in different jurisdictions.

Numeral is a sales tax solution with built-in global support

Brex found the partner it was looking for in Numeral. "Brex uses Numeral to help with global tax compliance," Levy said. "We serve companies all over the world. Numeral helps us calculate the global taxes for those customers, so we can focus on what we do best, which is building spend management software and corporate card software."

Numeral's tax calculation engine integrates directly with Brex's sales platforms and accounting software to calculate tax in real-time, ensuring that Brex collects the right amount of tax due from customers. Numeral also tracks the company's sales, alerts Brex when it's approaching a nexus threshold, and automatically registers and files for the company once it establishes nexus.
