Change last page

Hi i wanna know how can i change the last page
like : "thanks to buy with us" ?

What do you have actually as the last page ?
Can you do a screenshot and give the URL in your browser address bar ?
Because there can be several thank you pages in HikaShop based on how you configure it.

Do you know when you finalize your purchase?, you will see a page where they confirm that the purchase was made with success .... is this page that I want to change.

Sure but as I said, the page can be displayed by different views based on your payment plugin, and the options in HikaShop. We need more information in order to answer you precisely.
Can you do a screenshot and give the URL in your browser address bar ?

the page is

Wwww.vixycomercio.com.br

You can change that text by editing via a translation override:
