Multi cart checkout in hikashop

Hello,

From what you said I can't be absolutely sure that HikaShop can do what you needs.
To be sure of your needs can you details your need and especially the rental managing, as :
=> Precise what you mean by credit payment, do you need recurrent payment or subscription system or pending or else ?
=> Do you need to remove rental product from stocks and go back at the end of the rental period or that can be manually manage on your side ?
=> Other details that can able us to better understand your needs and any parameters to manage.

Regards
