Software and apps · delivered in 2 days
PBN.LTD builds landing pages, calculators and web apps (including progressive web apps) from scratch using HTML, CSS and JavaScript. Rather than adapting a template, we write the code to match your brief, which keeps it lean, maintainable and free of the quirks that come with reused themes. Particular attention goes into mathematical logic, so calculators and interactive tools return accurate results and the interface stays reliable.
· A landing page designed around your brand
· Interactive calculators or forms with proper data validation
· A layout that works equally well on phones, tablets and desktops
· Progressive web app features, including offline capability where relevant
· Code that has been checked thoroughly to avoid calculation errors or display faults
We focus on getting the user experience right, not just producing working code, and we keep you updated on progress as the build proceeds.
1. You share your brief and requirements
2. We send back an initial design concept
3. We develop the solution and show it to you
4. We hand over the clean source code, ready to upload to your server
This service suits businesses that need a working landing page, calculator or small web app quickly, without committing to a long development cycle, and who want to keep full ownership of the source code afterwards.
Your order opens its own thread here the moment it is paid, and everything about that order - questions, changes and the final report - happens in it.
Yes. Once the project is finished, you will receive a ZIP file containing the full source code (HTML, CSS, JS), organised and ready to upload to your own hosting.
Your order includes 2 rounds of revisions. If you want changes to colours, fonts or the calculator's logic, we will adjust it within those rounds until you are satisfied.
Yes, every build is fully responsive, so it will display and function correctly on mobile phones, tablets and desktop computers alike.

Automated tests check your key booking, enquiry or payment journeys on phone and desktop, with a pass or fail report showing exactly what broke.
