First, direct your client to their Gifts Received page. If it was a PayPal payment, they should login to their PayPal account and click the History tab to search for the transaction. If they don't see the transaction in their PayPal account, it's likely the gift giver failed to complete the payment process on PayPal's website.
If it was an offline payment (cash or check), they should expect to see that in the mail or receive it in person from their gift giver.
For any type of gift, they can send a tasteful reminder e-mail to the gift giver, from Honeyfund, by clicking the gift on the Gifts Received page, then clicking "send reminder."
If you have any questions, please contact us.
