Hello,
Fist, which Stripe plugin are you using ?
In HikaShop payment plugin you can configure the "return url" which is a thank you page. When the payment is done and validate, the customer is redirected to that page.
For some payment plugin, the confirmation of the payment is made in a second time, like for example with Paypal which use a "server-to-server" system to indicate that the payment has been successfully made. That notification can be receive several minutes after the order ; so it is very complicated in such case to have a notification within the website.
