I remember posting this line on my social network accounts. Obviously, I have more credit on my card as compared to cold cash. In all honesty, I prefer transactions using my card but in reality, cash is still the most preferred payment method in most merchants.
For online activities, paying in cash is definitely not an option. Most of the establishments present in the internet requires you to pay using your credit card or online payment facilities like Paypal.
So I suggest, if you are going to expand your business online, prepare your ACH Payments system to somehow give a hassle-free experiece to your clients and customers.
