Paypal has become a well-known industry standard and is certainly trusted. Exponentech helped Global Harmony Community Chorus to create a donation page on their website so that supporters can contribute to their global relief efforts.
Paypal supports a variety of options and makes it easy to track incoming payments. Currently, Paypal charges 3% + $0.30 as a processing fee. If having online payment will increase your business, then this is definitely a worthwhile way to do so.
Whether for-profit or non-profit, Exponentech can help you set up Paypal and get the revenue flowing!
