WIX Payment Links

Is there a limit to the amount of active/inactive Wix Payment Links we can send via the Wix Editor. I’m looking into creating a site for a group of 13 anesthesiologists who have various pricing based on each patient’s dossier. They’d like to give each patient a specific payment link, and I’m worried that there might be a limit to how many links can be created / be activated.

ALSO: if they accept payments through Stripe, will they then have Stripe fees AND Wix fees for the pay links?

Confused! Thanks for your help!
