When a person, who has never visited our website, pays for a product on our site, and chooses not to save the credit card information on the checkout page, "Guest" is passed to our payment gateway, Stripe, as the payer's name. Also, the payer's email address information is missing. This causes additional work for our accountant, who must look up the payer's name, for our accounting system. Please pass the payer's name and email address for all transactions. Attached is a screenshot from our test Stripe account. We are on IPS version v4.7.14
You can duplicate the error by going to our development site. Typically, the person starts by selecting the Parent Membership product on our registration page - https://stage.npnparents.org/store/?do=register . The system then prompts the person to create a profile during the checkout process.
FYI: we use Quickbooks for our accounting system. Our accountant downloads the transactions from Stripe and imports the transactions into our Quickbooks account.
