We are looking to purchase a developer's licence to create a form that the user will select between 3 products, multiple options for each and at the end be presented with a total cost. From there they need to be able to pay directly with pay-pal or “submit” the order to us and pay by cheque in person. Can we do this with Gravity forms? We do not require a shopping cart as there will only be one total generated by the user's answers on the form.
