CUSTOM FUNCTIONALITY. CLEAR PURPOSE.
Make your website work the way your business does.
PHP development built around your requirements.
Seller’s Bay develops custom PHP websites, web applications, online stores and content management features. We help turn a business requirement into a practical development plan.
You may need a new application, an integration between existing systems or support for a site that has become difficult to maintain. We start by understanding your users, existing technology and priorities.
For projects that also need a new interface or broader functionality, explore our website development services.
OUR PHP DEVELOPMENT SERVICES
From a single feature to a custom application.
Choose focused development support or bring us the brief for a larger build.
Custom PHP web applications
Develop customer portals, member areas and business tools around an agreed workflow. Define the essential functionality first, then plan improvements as your needs evolve.
PHP eCommerce solutions
Build or extend store functionality to fit your products and operations. Plan checkout, order handling and connections to other systems alongside the customer experience.
PHP-based CMS development
Create content management features that match your publishing needs. Give your team clear controls for routine updates while keeping custom functionality maintainable.
API development & integration
Connect your website to the services your business relies on. We review the available APIs, authentication, data mapping and error handling before defining the integration.
PHP frameworks
Our PHP services include projects using Laravel, Symfony and CodeIgniter. The framework choice should fit the application, existing codebase and long-term maintenance needs.
PHP migration & modernization
Review an older application or plan a move to PHP. Check code, dependencies, hosting and data before making changes, with testing and a rollback plan for the transition.
MAINTENANCE & SUPPORT
Keep your PHP website supported.
Development does not end at launch. Plan updates, troubleshooting and future features alongside the initial build.
Explore our website maintenance packages or WooCommerce maintenance for ongoing care.
Supported software
Use a supported PHP branch and review the compatibility of your framework, extensions and hosting before an upgrade. A version change should be tested against the application’s important workflows.
Security-conscious development
Access controls, input validation and careful handling of data belong in the development plan. Agree any specialist security testing requirements as part of the scope.
Performance & reliability
Review slow requests, database queries and external integrations when investigating performance. Backups, logging and a rollback plan help make changes easier to manage.

YOUR QUESTIONS, ANSWERED
PHP development FAQs
Can you work on an existing PHP website?
Yes. We begin by reviewing the codebase, hosting environment and the changes you need. That review helps establish the scope, dependencies and testing required before work starts.
Do I need a custom application or a CMS?
It depends on the workflows and features you need. A CMS can make content updates straightforward; custom development can address more specialized functionality. We can help compare the options against your brief.
Can you connect my website to other systems?
We offer API development and integration. Share the systems you use and what data needs to move between them. Available APIs, access permissions and provider limits will shape the solution.
Which PHP version should my website use?
Choose a supported version that is compatible with the application, framework and hosting. Check the official PHP support schedule and test an upgrade on staging before applying it to production.
How much does a PHP development project cost?
The estimate depends on functionality, existing code quality, integrations, migration and testing. Tell us about your project and its priorities so we can work through the scope.
Can you provide support after launch?
Yes. We can discuss ongoing maintenance, troubleshooting and new features. Agree the support scope before launch, including who manages hosting, backups and software updates.
