I need a WHMCS-savvy developer to overhaul my order form so it both looks and behaves exactly the way my brand requires. The job spans every layer of the template: the visual design, the underlying fields, and the business logic that powers them. Design & layout • Refresh the colour scheme to match my existing website palette. • Rework the overall layout structure for a cleaner, more intuitive flow. • Adjust typography so headings, labels and body text feel consistent with the rest of the site. Functional upgrades • Build automated calculations that update totals and discounts in real time. • Add custom validation rules to stop incomplete or invalid submissions before they hit the cart. • Hook the form into a couple of external APIs (one for tax, one for a promo engine) so the data exchange happens seamlessly. Technical notes The current WHMCS install is on the latest stable release, running the standard Six template with minor tweaks. I’m comfortable giving you full template and theme access along with a staging environment. Clean, documented PHP/Smarty, CSS and JavaScript is a must; I want to understand how things work long-term. Deliverables • Updated template and stylesheet files ready to drop into /templates and /assets. • Any custom modules or hooks you create for the new logic and API calls. • Brief setup notes so I can replicate everything in production. • A short walkthrough video or screenshare proving the form behaves as specified. If you know WHMCS inside out and can turn this list into a polished, reliable ordering experience, let’s talk.
