ScholarPack does not have a payment system as part of our software, but we do integrate with other companies who offer this facility, via API.
If you go to Admin > Config > API Configuration you will find alist of companies that ScholarPack has direct electronic links with (e.g. Parent Pay).
Other companies may integrate via Data Aggregators, such as Wonde and Groupcall. Please see this article for further information: Why Can't I Find the Company I Need on your API List?
NOTE: If setting up an API with Wonde or Groupcall, these are often set as 3rd Party APIs, and therefore student contacts must be set to Allow Contact by 3rd Parties in bulk (click here for details).
