About the service
I create cost calculators for windows and glazing for websites of companies that sell and install windows, doors and balcony systems. Instead of calling or submitting a vague inquiry, visitors enter the width and height of the opening themselves, choose the profile system, type of glazing unit, specify the number of sashes and type of opening — and in a few seconds see the exact price on screen, already including standard installation.
When setting up the calculation logic, I rely on the client's real pricing: base rate per square meter by profile line, markup for casement and non-standard sashes, glazing unit upgrade, sills, reveals, removal of old windows, delivery by district. Coefficients can be moved to a separate table or price list that managers edit themselves without contacting the developer. The calculation on the client side works instantly, and the total amount is double-checked on the server before the inquiry becomes a lead.
The result is not a toy for the website, but a real sales tool: the calculator captures a warm inquiry with specific configuration, and the manager already knows exactly what the client wants before the first call.
What's included in the work:
— responsive calculator widget for desktop and mobile
— manually editable price rules and coefficients
— inquiry collection with full configuration
— integration with current website or inquiry system
