Terms of work

Last updated 14 October 2026

This page explains how we work. For each project the signed written scope is the agreement, and where the two differ, the scope wins.

Price and payment

• A fixed price, agreed in writing before anything starts. No hourly billing.
• Sixty percent to begin. The balance when the work goes live, after you have seen it working.
• Invoices are issued by Pureheart Devea Orugbo, trading as Orugbo Studio, in pounds, euros, US dollars or naira, as agreed in the scope.
• Anything outside the scope is quoted to you first and only done once you agree.

Time

The calendar starts when your pricing or sizing rules are signed off, not when the deposit arrives, because the build depends on them. The scope states the date, and one review round is included before launch.

What a calculator promises

A calculator gives your customer an estimate based on the rules you approve. It is not a binding quotation; your business sets the final price. Engineering tools, such as heat pump or refrigeration sizing, give an indicative figure and do not replace a survey or a design by a qualified person, and they say so on the page.

Your part

An hour with whoever does your quoting today, your rules written down once, and replies to review requests within the agreed time. If the tool has to connect to your other systems, we agree that connection and any access it needs in the scope.

Care plan

Hosting, rate changes and a monthly usage report, on a monthly fee stated in the scope. You can cancel any month with notice before the next invoice.

If something is wrong

Tell us and we put it right. A defect against the agreed scope is fixed at no charge. Our total responsibility for a project is limited to the fees paid for it.
