Might be an odd topic I know but I've been using PayPal for years now, mainly small sales and for transferring money to family and friends. I also typically do cash in hand but a customer the other day told me to get a real app for invoices as PayPal isn't meant for that? I'm very confused by the whole thing but my daughter seems to share his sentiment, she said no one she knows outside of the family uses the app.. have I lost track of the times or something?
