We don’t know why the Chase Ink Business Preferred card used to earn 3X for Plastiq bill payments, but it did. It was sweet while it lasted, but according to Doctor of Credit that deal died as of August 16th.
I don’t have any recent enough charges to confirm this change, but I can vouch for the fact that the Ink Business Preferred / Plastiq combo was earning 3X as recently as August 14th.
A good alternative in the short term is to pay bills with a Mastercard credit card: you can use Plastiq to pay bills up to $250 fee-free with a Mastercard via MasterPass through the end of September.
