Blackbaud should make their eReceipt feature pack part of core instead of trying to charge customers more for this "feature".
Blackbaud makes products for non-profit companies to manage transactions and donations through online portals. They are pushing their clients to go to their hosted solutions. So it seems outrageous that they don't natively support a functional eReceipt process.
This is a feature that can be used across all verticals as all non-profits are in the business of raising donations for their specific causes. In their demo video https://resourcehub.blackbaud.com.au/youtube-all-videos/ereceiptdemonstration they show it is a custom part in BBIS and some extended functionality in BBCRM.
Adding this to BBCRM/BBIS core would really benefit the donation experience for all donors as well as relieve a lot of stress and unnecessary work from employees
