Interactive Service Quote Calculator

Interactive Service Quote Calculator

This self-initiated web prototype turns a small set of pricing rules into an itemized estimate. The example is fictional and is not an offer to sell a service at the displayed price.

Six inputs control setup cost, quantity, unit price, the one-time discount, monthly support, and support duration. The sample produces a US$702 project subtotal after discount plus US$180 of support, for US$882 before taxes and payment fees. The calculation uses integer cents and rounds the discount once. Negative amounts, fractional unit counts and excessive discounts are rejected.

Users can change inputs, reset the example, and download the estimate as text. The responsive interface runs in the browser without external libraries. Browser checks verified recalculation and invalid-input handling, alongside arithmetic boundary tests. Built with AI-assisted development. A real implementation starts with the client's approved pricing rules.
