You can enter the card info manually to process credit cards on the go, info2280.
Before anything else, I would like to know the issues you encountered when using credit cards in the app. Were you unable to add the card information and face errors? Did you manually enter the card information, but the transaction is still declined? Is the payment intended for a new sale, an existing invoice, an advance payment, or received in person? Any additional details can help us provide a more suitable resolution.
In the meantime, consider uninstalling and reinstalling the app or using different devices to get your GoPayments app working. This action helps refresh the app and isolate its case. Please also make sure you have a stable internet connection when doing so.
Alternatively, I recommend contacting our live support team if the issue persists after the troubleshooting. Rest assured that they can look at your account and transaction logs in a secure environment.
Once resolved, refer to this article for complete instructions on choosing the Key in card as a payment method to manually enter the credit card details: Process payments in the QuickBooks mobile and QuickBooks GoPayment apps.
