Portals and Websites Built for the People Who'll Actually Use Them

A customer portal or partner site is the part of your business people outside your team actually see. We design and build web applications, self-service portals and websites that are fast, easy to navigate, and built to reflect how your business runs, not a generic template.

Service Overview

At Calculate Capitals, we design and build customer portals, partner portals, self-service dashboards and business websites. That might be a login area where clients track their own orders or projects, a partner portal for resellers and vendors, or a corporate website that needs to do more than sit still. We work in short sprints with regular demos, so you see the design and functionality take shape every fortnight. Every build ships with responsive design, security testing, and support after launch.

What's Included

Every web or portal project covers the full lifecycle, from the first wireframe through to launch and the support period that follows.

Why Choose Calculate Capitals for Web & Portal Development?

Most portal and website projects fail on usability, not code. We fix that with a working prototype early, real user testing before launch, and a named lead who takes the build all the way through to go-live.

"The entire ERP transition was seamlessly handled. They took the time to understand our workflows and made sure the system was a perfect fit for how we operate"

Marketing Director

"We were counting stock by hand across four sites. Two months after go-live, our warehouse team stopped reconciling spreadsheets entirely."

Managing Director

"They customised the CRM we already owned instead of selling us a new one. That single decision saved us a year of migration work."

James Peterson

Founder

"Fortnightly demos meant no surprises. We saw the app taking shape every two weeks and launched on the date they gave us in week one."

Common Questions About Mobile App Development

What's the difference between this and your Custom Software Development service?

This service covers anything your customers, partners or the public interact with directly — portals, self-service dashboards and websites. Custom Software Development covers internal tools your own team uses. Many clients use both, connected to the same backend.

Yes, that’s one of our most common builds — a secure portal showing each client only their own orders, projects or account information.

A focused website typically takes six to eight weeks. A portal with logins, user roles and integrations runs longer. We fix the timeline at the scoping stage.

Yes. Most portals we build pull data from a system you already run, so what a client sees on the portal is always up to date.

Yes, every build is responsive by default and tested across devices before launch.

A warranty period is included with every build. Most clients then move to a support agreement covering fixes, content updates and new features.
