FIRST READ, POST OFFER AFTER. I'M SICK OF ROBOTS

FIRST READ, POST OFFER AFTER. I'M SICK OF ROBOTS I have a wordpress site and I need some little code customizations. My website offers a service based on minutes. I have bought a plugin ([login to view URL]) that easly provide my customers with a beautiful and simple user interface to choose the amount of minutes and some extras that can be added to the total price. This plugin does all the calculations and operations I need around my minutes based service. The plugin is also able to send the total amount to be payed to PayPal and state all sales and able to select options that can be WooCommerce products that can be at the final step added to its cart to proceed checkout via WC. I need to finish payment via WooCommerce, adding the total price the plugin outputs at the end to the WC cart. My problem is that my product is based on calculations, and that, leads to thousand of possible products in WooCommerce wich is not an option. How can this be done? I have a sort of way: This plugin outputs an exact amount to be payed at the end of the estimation process. The plugin sends this amout via e-mail, to PayPal to proceed payment step and also stores this amount in its little database. This amount I'm sure that can be sent to a Woocommerce, forced to the cart using some kind of code. That's exactlly what I need. DOC & EXAMPLES: My website with this estimation plugin: [login to view URL] Other website of mine where this estimation plugin add everything to WooCommerce cart, but on this website, the service it's not based on calculations: [login to view URL] Access to the backend of an example site with estimation plugin installed and woocommerce: ask for URL and credentials in private.
