I spend approximately 100K a month on a Plat. I need to split up the spending on the card for tax and accounting purposes in to 2 different companies, so I would like to apply for an SPG Biz for the 2nd company. My only hesitation is that I never had an issue with Plat as it is a charge card, but from what I understand SPG Biz is a credit card. How can I ensure that I get the CL I need?
