The challenge
The organisation's pricing depended on several interacting inputs—the shape of the business being set up, the services required, and the categories attached to them. Prospective clients could not work out what something would cost without asking, and answering those questions individually consumed the team's time.
The difficulty was not arithmetic. It was that the rules had grown organically, held partly in documents and partly in people's heads, and had never been written down as a single consistent model.
The approach
The first phase was specification rather than development: reconstructing the pricing rules explicitly, finding the places where two rules disagreed, and getting a decision on each before any of it was encoded.
The interface then had to disclose complexity progressively. A form presenting every input at once reads as a questionnaire and gets abandoned; inputs that appear as earlier answers make them relevant keep the tool usable.
What I delivered
A custom Sitefinity widget with dynamic inputs, conditional business logic and structured pricing rules, producing a calculated total with the contributing factors visible rather than a single opaque figure.
Validation runs on both client and server, and the calculator is responsive because a decision-maker is as likely to reach it from a phone as a desk. It is built as a reusable component configurable from within the CMS.
Outcome
A prospective client can reach an informed estimate independently, and the organisation gained a single authoritative expression of rules that had previously been distributed across documents and individuals.
Because the pricing structure lives in a configurable component rather than in hard-coded markup, the rules can be adjusted without re-engaging a developer for each change.
