Hello, Lisa. Your clients can still make payments using a card or Apple Pay in QuickBooks. We can guide them through some troubleshooting steps so they can successfully pay their invoices. An accumulation of historical data can lead to unexpected behaviors.
Please advise your clients to open and pay the invoice using an incognito window to eliminate potential webpage issues. Here are the following keyboard shortcuts they can use:
- Google Chrome and Microsoft Edge: Ctrl+ Shift + N
- Mozilla Firefox: Ctrl + Shift + P
- Safari: Command + Option + P

Once the payment options appear, they can return to their regular browser. It's also a good idea to clear their cache to start fresh. If the issue persists, they can consider switching to other supported browsers installed on their system.
If the issue continues despite taking these troubleshooting steps, I recommend contacting our live support team. Our experts can further check the reasons for the missing payment options for cards and Apple Pay in more detail.
Moreover, you can send your customer a statement that provides comprehensive details of their associated invoices, payments, and outstanding balances for future reference.
I know how important it is for your clients to have flexible and convenient payment options directly through the invoices you send. If you have further questions, let us know below.
