Software that fits your business, not the other way round

Off-the-shelf software is built for everyone, which often means it fits no one perfectly. Antigua Web Solutions designs and builds custom web, mobile, and internal business applications for companies that have outgrown generic tools. We take care of everything from planning and design to development, integration, and long-term support, so you end up with a system your team actually wants to use.

How we work

Six clear stages, from the first conversation to long-term support.

Six-step custom software development process from discovery to support

Discovery
We learn your goals, users, and current process, then agree on scope, timeline, and budget in writing.

Development
We build in short stages so you can review real progress along the way and request changes early.

Launch
We deploy the application, migrate your data if needed, and train your team.

Design
We plan the structure and user flows and share wireframes or mockups for your approval before any code is written.

Testing
We test on different devices and browsers, check security, and fix issues before launch.

Support
We offer maintenance, updates, and improvements after launch, so the software keeps pace with your business.

Frequently asked questions

How much does custom application development cost?

The cost depends on the features, number of users, integrations, and platforms. A small internal tool costs far less than a full customer platform. After a short discovery call we provide a written estimate with a clear scope, so you know what you are paying for before we start.

How long does it take to build a custom application?

Simple applications can take a few weeks, while larger systems usually take several months. We break larger projects into stages, so you can start using the most important features sooner.

Will I own the source code?

Yes. Once the project is paid for, the code and the finished application belong to you.

Can you connect the new software to the tools we already use?

Yes. We regularly integrate with accounting software, payment gateways, CRMs, email platforms, and other systems through their APIs.

Do you provide support after launch?

Yes. We offer maintenance plans that cover bug fixes, security updates, backups, and new features as your needs change.
