Your showroom deserves
an online showroom

Accurate pricing for blinds, curtains, and shutters — calculated instantly on your Shopify store. No more spreadsheets. No more missed sales.

🇺🇸 USA · 🇬🇧 UK · 🇦🇺 Australia · 🇳🇿 New Zealand · 🇨🇦 Canada · 🇪🇺 EU

The industry runs on
guesswork

  • Manual quoting — hours spent on emails and phone calls for every order
  • Pricing errors — one wrong measurement and your margins disappear
  • Lost sales — customers leave when they can't get an instant price online
  • Regional complexity — different suppliers, currencies, and rules for every market

What if your store
could quote for you?

Imagine a customer lands on your site, selects their blind type, enters their window measurements, and gets an accurate, real-time price — including fabric, size brackets, and regional pricing rules.

No phone calls. No waiting. No errors. Just a confident customer clicking "Add to Cart" at 11pm on a Tuesday.

That's what we build.

Built by someone who
gets the industry

Darius didn't set out to build software. He set out to solve a problem he kept seeing — talented window furnishing retailers losing online sales because the technology didn't exist to quote custom products accurately on a website.

So he built it. Not a generic tool with a blinds skin on top, but something designed from the ground up for the way this industry works — width-by-drop pricing, fabric tiers, regional suppliers, made-to-measure complexity.

InteriorShopApps exists because the interiors industry deserves technology as considered as the products it sells.
