As a small business owner, it wasted hours of my life for no good reason.
We’ve been using two capital one cards for all of our expenses (in the hundreds of thousands per month), and have really enjoyed the benefits of 2% cash back.
The biggest issue is the credit limit. Even after 12 months of making 4-6 payments for the entire credit limit throughout the month (we max the card out every week at least), they still won’t give us the limit we need. Sometimes they even make up bogus excuses on the credit request response form Such as “account cost too high” (or something like that)
Had the same experience with the same card, asked multiple times for a credit increase ... which they denied. Then they increased it months later when I didn't ask. Go figure.
The Amazon Business card from Amex is great for Amazon spending, products and AWS included.
Is there an equivalent for Azure?
It's really easy to believe the deal when you look at your interchange rates. The Capital One that I mention above has 2.3% interchange rate, so the merchants who take it get hit much harder than other cards. Capital One, stripe, amex etc are all still making a killing on these cards, they just do it on the backs of the merchants who accept them.
Based off our business spending on our card, which isn't extreme by any measures (18 employees, bootstrapped and cash flow positive, doing fairly decent), it probably beats that stripe card even with the processing fee bump.
