Web apps & custom development in San Antonio, TX.

Need a custom web app for your San Antonio, Texas business? GEO Marketing Group designs and builds booking systems, customer portals, dashboards, and calculators for San Antonio companies, working remotely from our Providence, RI studio. We build the custom functionality a template cannot handle, with clean code you own outright.

San Antonio's economy is built on a diverse set of pillars: Joint Base San Antonio is one of the largest military complexes in the country, the South Texas Medical Center hosts dozens of hospitals and research institutions, and a thriving tourism industry supports thousands of hospitality, retail, and service businesses year-round. The city's manufacturing base, anchored by Toyota's North American truck plant and a growing cybersecurity and technology sector centered on Port San Antonio, adds further depth. Behind all of that sits a vast ecosystem of contractors, clinics, law firms, restaurants, and neighborhood businesses that collectively make Bexar County one of the most active local markets in the Sun Belt.

FAQ

Web Apps in San Antonio: common questions.

What kind of web apps do you build?

Booking and scheduling systems, customer portals, internal dashboards, calculators, and other custom tools that go beyond a brochure website. If your business runs on a workflow a template cannot handle, that is exactly what we build.

Do you work remotely with businesses outside Rhode Island?

Yes. We are based in Providence, RI and build for clients across the US and Canada, working remotely by phone, video, and email. Web app projects run smoothly from anywhere.

Do I own the application and its code?
