PayXT is a mobile invoicing application designed for field service professionals and contractors. The software enables users to generate itemized checkout links from their mobile devices and send them directly to clients via SMS text message. PayXT integrates with Stripe for secure payment processing and includes built-in tools for calculating localized sales tax and applying credit card convenience fees to the final invoice. The platform is designed to facilitate on-site payment collection without requiring external hardware readers or forcing clients to download a companion application to submit their payment.
