Hi @mrdaro,
Thanks for your input. I understand that generating a large number of PDF receipts during a short time period wouldn’t be scalable to large or rapidly-growing donor bases. However, we are a small, and relatively localized, non-profit organization with a base of fewer than 100 donors that isn’t expected to get much bigger any time soon. If we were to separate the timing of each donor’s receipt by 2 minutes, it would take less than 4 hours to cover all of the donors and there is no reason our server wouldn’t be able to handle it.
