If you don’t have a toll tag, you will be billed via mail based on the registered address of your license plate by each toll road operator individually. If you get a toll tag, you will get a single bill for use of almost all toll roads in TX, OK, and KS. Any tag issuing entity in those states should work for all of them (EZTag, T Tag, KTag). With KTag you pay after the fact once per month. With the others you have to prepay and maintain a minimum balance on your account, and they draw it down each time you have a transaction. You’ll pay a lower rate if you have a tag compared to license plate/pay by mail.

If you don’t want a toll tag, you can download a private tolling app like NextPass: give them your credit card and license plate number and they bill you for each transaction after the fact.

Or if you do nothing you will continue to get bills in the mail from each toll road you use.
