Case Study: CeloPay achieves secure, mobile billing workflows with Dropbox Sign

CeloPay Modernizes Outdated Processes with the Help of HelloSign's API

CeloPay, a Georgia-based payments service founded in 2011, set out to replace insecure, paper-and-fax billing workflows commonly used by hotels and other businesses. Faced with customers reluctant to share sensitive payment details over fax or email, the company needed a secure, compliant, and user-friendly way to request and collect billing information.

CeloPay embedded HelloSign’s API to add white‑labeled, mobile‑optimized electronic signatures directly into its billing request flow — an integration completed in about a week. The result is a seamless in‑app process that speeds collections, provides legally binding authorization for dispute protection, and has earned consistently positive customer feedback for being cleaner, simpler, and mobile-friendly.
