Web apps & custom development in Philadelphia, PA.

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

Philadelphia's economy runs far deeper than its history. The city is anchored by a cluster of world-class health systems - Jefferson Health, Penn Medicine, Temple Health, and Children's Hospital of Philadelphia among them - plus Comcast's global headquarters, a major Delaware River port, and a dense ecosystem of law firms, financial services, and professional practices. Drexel, Penn, Temple, and a dozen other universities make it a steady source of startups and knowledge-economy businesses, while neighborhoods like Fishtown, Manayunk, and Old City support thriving concentrations of restaurants, retailers, and creative studios. For all of them, the first impression a customer gets is almost always the website.

FAQ

Web Apps in Philadelphia: 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?

Yes. The code, the hosting accounts, and every integration are set up in your name and handed over at the end. You own the app outright and are free to host, extend, or move it however you like.
