I’m interested in buying this plugins

I’m interested in buying this plugins, I’m testing the free version and I solved my need momentarily, but I have a problem with variable products and I do not know if with the paid version would solve it, I want to upload on my website 13,000 products between them parents and their variations, currently can make a test with a simple product and one variable and both worked, but as I can apply these variations massively with the load of so many products importing it with a file .csv via csv import or WP All Import? in WP All Import this function that gives me this plugins does not appear there. I want to buy it but knowing that I will solve this problem. Thank you
