Custom Web Development Built for Your Business

From professional websites to custom web applications and integrated digital platforms, iDT develops secure and scalable solutions designed around real business requirements.

When off-the-shelf stops fitting

Most businesses start with a standard website and a handful of separate tools. It works until the manual steps between those tools start costing real time: re-typing orders, chasing spreadsheets, reconciling systems that do not talk to each other.

That is where custom development pays for itself. We build the functionality your process actually needs, connect it to the systems you already use, and keep it secure and maintainable so it can grow with you rather than being replaced in two years.

Frequently asked questions

Should I use WordPress or a fully custom build?

WordPress is the right answer more often than people expect: it is quick to build on, easy for your team to update, and handles most content-driven sites well. A fully custom build makes sense when the core of the project is business logic rather than content, when you need a genuinely bespoke workflow, or when the data model does not fit a CMS. We recommend based on the requirement, not on preference.

Can you integrate with systems we already use?

Usually yes, provided the system exposes an API or a supported export. We integrate with payment gateways, accounting tools, CRMs, calendars and email platforms. Where a system has no API, we look at what is realistic before committing to it in the scope.

Who owns the code once it is built?

You do. On project handover you receive the source code and the accounts it runs on. We do not hold clients hostage on access, and you are free to take the project to another developer.

What happens after launch?

You can take the system in-house, or we can keep supporting it. Ongoing support typically covers bug fixes, security updates, small enhancements and monitoring. We agree the scope up front so you know what is included.

How do you handle security?

We parameterise database queries, validate and sanitise input, protect forms against cross-site request forgery, hash passwords rather than storing them, and serve everything over HTTPS. For applications handling personal information, we also work to the requirements of POPIA.
