I want to be able to take payments a variety of ways - in person - over the phone - thru fb messenger. But I have no idea which product I should choose. Can someone please advise.
Square POS will handle your in person and email invoicing and online store payments. Square cash would be used for Facebook messenger. I don't think you need to worry about Square Retail (Square POS with extra features).
Start with Square POS and get that all setup and then see what else you would want to do.
