Not Receiving Orders

We have had now 3 different customers that there payment went through and the order never came thru on the sytist web page.  What would cause this?

Thank you 

I have had this. 

I use Stripe payment and the payment goes through but doesnt show on my order and then say an hour later the order will show up on my site.

Do you know which payment option? 

You have PayPal Advanced  Checkout enabled and also PayPal Standard Business. Since you are using PayPal Advanced Checkout, you should turn off the PayPal standard business since it is included in PayPal Advanced Checkout. 

And sometimes there can be a delay with the IPN with PayPal Standard Business. 

And PayPal will be retiring the PayPal standard business at the end of the year.

Thank you we will try that
