Hi All, I am quite new to Glide and currently building an inventory app and I have a requirement to have a billing and invoice section, I would need help in designing the billing section, I want a functionality where a user can choose products from inventory, have an add to cart button after choosing it asks for quantity and based on a quantity a new checkout page along with items total with all the added product should show Can anyone help to explain how should i proceed? ---

It would take a fair bit of typing to explain this but I have a better suggestion. Take a look at our templates to find an example to most closely match your idea, copy the template to your team and then take a look in the builder to see how it was made. Many builds will use very common types of setups, so even if the template isn’t a match it will likely have concepts that will put you on the right path.
