The T-Pop application is free: 0, zero, nula, nada.
We only invoice you when you make a sale, for the amount defined in the app.
You create your product using the app, we indicate the printing price of the product and the shipping costs, then you are free to set YOUR price and your profit margin.
Billing and payment are automatic, you don't even have to think about it.
Prices depend on the type of support you offer to your customers, they are accessible directly in the application.
