Will you have delivered the product&#x2F;service at issue at the time you charge the card or within a short period of time thereafter?  If so, it is highly likely you will not have any issue with Paypal.  If you are accepting pre-payment for something which cannot be delivered in full shortly after payment, it is likely that you&#x27;ll have to become conversant with Paypal&#x27;s published guidelines about this.<p>Spoiler alert: if you are in an events business, &quot;We emailed a ticket&quot; does not constitute delivery of the purchase.  Successful conclusion of the event constitutes delivery.  Most events businesses structurally need to pre-sell tickets.  They will, virtually inevitably, have more issues with collecting payments than e.g. a software company which says &quot;You give us a credit card we give you a working download link.&quot;  This is not a result of caprice by Paypal -- more than 1% of scheduled events fail to actually happen; when that happens, Paypal gets hit with hundreds of chargebacks.<p>More details: <a href="https:&#x2F;&#x2F;www.paypal.com&#x2F;webapps&#x2F;mpp&#x2F;brc&#x2F;presale-policy-and-reserves" rel="nofollow">https:&#x2F;&#x2F;www.paypal.com&#x2F;webapps&#x2F;mpp&#x2F;brc&#x2F;presale-policy-and-re...</a><p>Events businesses: <a href="https:&#x2F;&#x2F;www.paypal.com&#x2F;webapps&#x2F;mpp&#x2F;brc&#x2F;account-reserves-tickets-and-reserves" rel="nofollow">https:&#x2F;&#x2F;www.paypal.com&#x2F;webapps&#x2F;mpp&#x2F;brc&#x2F;account-reserves-tick...</a>
