WEX Inc. is a global commerce platform that simplifies the business of running a business. Many of our customers face the challenge of managing complex operational processes due to the rapid pace of regulatory, economic, and societal change worldwide. They are often stretched thin and lack the in-house expertise to solve these intricate problems. This is why WEX offers personalized technology solutions designed to simplify employee benefits, mobility and fleet management, and accounts payable and receivables processes. From our origins as a pioneer in fleet card payments in 1983, we have expanded our scope to become a multi-channel provider of corporate payment solutions, helping businesses navigate these complexities and achieve greater efficiency.

Our customers in the fleet industry, for example, need robust tools to manage fuel and maintenance expenses, ensure driver safety, and optimize operations. WEX Fleet provides them with fuel cards, telematics, and data analytics to meet these needs. For businesses involved in travel, managing cross-border payments and streamlining back-end accounting can be a significant hurdle. WEX's travel and corporate solutions, including virtual payment solutions, help these clients automate processes, reduce costs, and gain better insights into their spending. Similarly, in the healthcare sector, employers and employees alike grapple with the administration of benefits and healthcare payments. WEX Health offers a cloud-based platform to simplify the management of Health Savings Accounts (HSAs), Flexible Spending Accounts (FSAs), and other benefit plans, making it easier for millions of consumers to manage their healthcare expenses. By embedding our solutions into our customers' workflows and leveraging our expertise in data and analytics, we empower them to make smarter decisions, reduce operating costs, and ultimately, reach their full potential.
