Hi Flight777,
I am currently looking for a non-AMEX business cc. In case if helps I am favouring the ANZ business one (0.67 points) with QF, or BankWest (effectively 1.5 pts per dollar).
For vouchers, I get more via Bankwest ($850 per 100,000 spend compared to $530 with ANZ) but no QF points for upgrades.
Depending on your business use, you may be able to get away with a non-business cc. My business spend on personal cards (CBA Plt's) has never been questioned when I buy servers, office equipment, o/s travel, hotels etc.
But, we have had plenty of problems with cc providers for the cards used for daily payments of government fees (millions a year), all to the same biller. Hard to pass it off as a non-business expense!! When the cc provider wakes up, it can be uncomfortable.
Regards
Johno
