Many small businesses rely on cash flow to pay for suppliers or contractors, because they need to purchase materials and services before their own clients pay up. You need to calculate difference between date when you purchase materials and date when clients pay you back. If this is shorter than 30 days, go for a card that doesn't charge you interest for respective period. If it is two, three months or longer, go for a low interest card.

Also, you should think of how often you will have to travel for business-related purposes, and how a special type of credit card can help you with this, or how you will handle unprepared emergency situations that hustle small businesses constantly.

After you actually have card and you start spending, make sure you spend wisely. If, for example, card only offers rewards when shopping in a certain type of store, go there and buy what you need form that place. Pay attention to policy on your gas card as there are gas credit cards that only offer rewards when paying for gas purchase at a gas station belonging to a particular chain. None less, before making any spending decision you need to think if you have enough credit to pay for card line at end of month. You may win some cash-back bonus or a plane ticket, but this will be of no use if you will be in dept and unable to pay your credit card bills.

It may sound complicated and difficult at first, but once you learn trick it will become a habit and you will see that you can spend money from a credit card and win some back at same time. Be careful with what card offers and what conditions are for you to be given your reward; choose separate cards for separate kinds of expenditures; spend money in places where issuer recommends - if you can manage with all these you are on right track to getting most out of your credit card reward program.
