EuropaSign: Website and Pricing Engine

EuropaSign makes custom LED acrylic letters, the kind that end up on a shopfront. I built their website and then, more usefully, the pricing engine behind it.

Every order is made to size, so the price depends on width, height, quantity and finish. All of that logic lived inside the order form itself as a pile of formulas. Form-builder formulas are a terrible place to keep business rules: they’re hard to read, impossible to test, and anyone who wants to adjust a margin has to edit a formula field inside a form editor without breaking the rest of it. Mistakes went straight through to live quotes.

So I wrote a custom WordPress plugin that splits the two apart. The form is now purely the interface, it collects dimensions and options and nothing else. All the actual pricing lives in its own admin panel, where rates, surcharges, finish multipliers and quantity breaks are editable fields with names instead of formulas buried in markup. The price still calculates live as the customer fills the form, so the number updates as they type.

Changing a price is now a two-minute admin job rather than something you do carefully with your fingers crossed.
