Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCoverage Calc adds a calculator to product pages for items sold by coverage, such as tile, flooring, paint, turf and soil. Shoppers type their room dimensions, the calculator adds your waste percentage, converts the total into your sales unit and rounds up. It shows the estimated cost and adds the exact quantity to the cart in one click.
Panelli is a configurator for stores that sell wall panels. Shoppers enter their wall size, pick a layout and colours, and see it in a room view. Where panels are compatible, ready-made layouts combine them. The app works out the panel count, edge trims and accessories with the store's rules and adds everything to the cart in one tap.
- Turn room dimensions into boxes, cans, bags or rolls with waste included
- Add the exact quantity to cart in one click, with the estimated cost shown
- Set up a whole collection at once; meters or feet, English or Spanish
- Combined layouts for compatible panels, plain for single types
- Automatic panel, trim and accessory quantities from wall size
- Every part added to cart in one tap; design code saved on the order
- Product matching, ready-made layouts and room scenes in the admin
