Checkout workflow

is there any documentation how to customize Checkout workflow?
For example I needed a step where customers are forced to accept terms of condition to continue. I see a field for terms of conditions... but I do not see them apear in Checkout workflow

Yes. here is the documentation: www.hikashop.com/en/support/documentatio...config.html#checkout

Please note that on each screen of HikaShop, you have a Help button where you can access the help related to the screen.

Yes, by default, the T&C view is not in the checkout workflow. You can add it and then you will have it displayed on your front end.
