We use Paypal for the majority of our transactions.. Just send customer a payment link and have them sign in as guest and "Walaaa"! For the more old school customers who are afraid of internet transactions we use our traditional merchant processor who charges us right under 2%... For the old school complicated accounting departments who don't have a P. Card we allow checks.. Very seldom do we see cash.. Also, with the paypal account, we have a paypal debit mastercard that gives us access to our funds without the 2-3 day delay when transfering to the bank. This process has really helped our receivables because with the paypal transactions, we get our funds instantly...
