We’ve been doing fine for 6 years taking only EMT but what does the customer think? Would it make a difference for you if we started to accept credit cards?
Yes, it will make a positive difference. Paying by EMT is less convenient for a large majority of people. Not to mention the other various incentives that people have to pay with a credit card - All of which help drive CC purchasing. Even for a disciplined credit card spender, the points, cash back, complimentary purchase insurance, and buyer protection when using a credit card make it a no-brainer.
That said, I buy from you through your website despite your payment system - But the deals have to be good enough to overcome the disincentives to paying by EMT.
There is absolutely no question: You will increase your sales numbers if you start accepting credit cards. Whether or not it's worth it to you is the real question.
