I work a small non-profit historic house museum. We are wanting to upgrade our CRM system to become more integrated. We are looking into PayPal for our POS and e-Commerce option for our gift shop and online ticketing. However, I can't figure out if you can sell tickets through PayPal on our website. We are wanting tickets to be inventoried (so we can cap events at certain numbers) and scannable so we can scan a QR code or bar-code to keep track of the tickets at events. Is this possible through PayPal's business features?
