Local context
Delray Beach business context
Delray Beach's downtown is a small-business economy. The Downtown Development Authority reports that 95% of shops on Atlantic Avenue are small businesses, which makes rent and operating costs a live concern for owners. That favors lean, fixed-scope software over large custom builds.

Questions
Frequently Asked Questions
How far is App369 from Delray Beach?
App369 is based in Miami, about 55 minutes from Delray Beach by car (approximate). We have no Delray Beach office.
Can we meet in person in Delray Beach?
Yes, by arrangement. App369 works remotely and asynchronously from Miami, with written updates and shared progress builds. There are no standing meetings; live calls are available at $100 per 15 minutes.
I'm a small shop on Atlantic Avenue. What is a realistic first project?
Most small businesses should start with one thing: a booking page, an ordering flow, or a cleaned-up website. Our fixed-price offers start at $450 and are listed on the fixed-price page, so you know the cost before work starts.
How long does a typical project take?
It depends on scope. As a rough guide, a marketing website takes 4-8 weeks, a web application 2-4 months, and a mobile app 3-6 months. Every Delray Beach project starts with a written scope and milestone plan, so you know the timeline before any build work starts.
Do you provide ongoing support?
Yes. After launch we offer maintenance that covers bug fixes, iOS and Android OS updates, security patches, dependency upgrades and small feature work, so your Delray Beach app keeps working as the platforms change.
What's your pricing model?
App369 uses project-based pricing with a 50/50 payment structure: 50% upfront and 50% on completion. Current ranges are published on our fee structure page, and smaller fixed-price packages are available for well-defined work.
Can you work with existing projects?
Yes. We take over existing codebases, especially Flutter and Firebase apps, for code audits, bug fixes, new features and migrations. Delray Beach businesses with an app that stalled or a developer who left can start with an audit before committing to a larger build.
