Looking for recommendations on a business credit card.  I farm and raise cattle.  I generally spend 1.2 to 1.5 million annually in operating expenses.

We use amex but it has to be paid off every month. Most dairies use them also. High credit line is nice.

Check with your suppliers first.  Many companies do not take AMEX.

I use AMEX and I have actually talked several of my suppliers into accepting the card.

I mainly use Chase Ink.  Cash back of 1% - 3% depending on category (3% on gas is really nice).

I just went through the process of looking for a new business card with the intent of getting the most cash back possible. I wasn't interested in travel rewards or air miles and I don't want to be tied to one certain company or reward type. (air miles, Hilton rewards etc). I put $20-$30K monthly on the card and pay 100% of it off every month so interest rates didn't matter to me. After tons of research I ended up with the Chase Ink card and should be getting a $500 sign up bonus in another month. It's hard to get more than 1% across the board unless you find a card that gets 3-5% in certain categories but that doesn't help me because my expenses are with my suppliers and don't qualify for anything but the 1% cash back.



Also, as someone else noted not everyone takes Amex or Discover, so Visa or Mastercard is probably your safest bet.

This is true... I have called AMEX and asked about charges and they immediately take them off my bill.  

Last summer someone used one of my cards on July 4th to go on an internet spending spree.  My accountant asked me about it in December.  I called and they took all the charges off immediately.

This... Our use isn't that high usually... We do employee benefits so no real expenses that aren't billed to us other then lunches, strip clubs, and a small amount of office supplies, gas, etc.
