Hello community! I've done a lot of research on this and I can't seem to find an app that does this. Maybe someone here can help. We sell custom sized stickers and I'm looking for something where the customer can chose from a list of popular sizes/quantities OR input their own value if what they want isn't listed. Prices will change based on this value. The photo best describes what we're looking for. We've found some apps that will do some things we need but not all. If anyone could guide us in some direction, this would be extremely appreciated!
We were also trying to sell custom products and couldn't find an app to help us, so we built an app and put it on the Shopify app store: https://apps.shopify.com/custom-price-calculator
You can build any type of customization you want and allow your customers to insert inputs based on their needs.
