It will scare off the most desirable credit card lenders, because they'll see all those requests on your credit report. Select a credit card that works best for what you're going to use it for and how you'll pay it off. Look for lower interest rates, even if there are higher annual fees, when you know you'll only be paying a portion of your total outstanding bill. Look at what perks come with the card and whether you'll really use them. If you're thinking of starting a business, get new credit cards and increase your credit limits now while you're still employed.
Every entrepreneur needs emergency cash sometime.
But poorly managed, credit card debt can turn into financial junk food, stunting the growth of your company through paying exorbitant interest rates. And getting in over your head with credit cards can tarnish your credit history and make it harder to qualify later for loans from banks and other lenders. The right hand not knowing what the left hand is doing. If several employees have cards on which they're charging business expenses, or even their own cards under your corporate account, you could end up with a shock when the statement comes. Beware of mixing personal and business expenses on the same card.
