"Wallpaper calculator on a road to the Shopify app store"

In e-commerce, the conversion rate is what matters most to us as business owners. Nice visuals, beautiful interfaces, and even virtual reality tools can help boost sales and are nice to have for sure! But if you can’t sell online, just because your products are custom-made, none of these nice to have tools will make a difference.

That’s why an online calculator is essential. It lets you sell first, and then focus on improving your store with extra apps and other tools and features to increase sales.

How It Works

1️⃣ Customers enter their wall dimensions (width & height).
2️⃣ The calculator tells them how many rolls or units they need.
3️⃣ Pricing updates automatically.
4️⃣ They add to cart and check out with confidence!
