Hi mwillis-llc,
Being able to save the phone number on the added custom field would be a great advantage especially for customers who find this option helpful.
As of now, the said feature is unavailable in QuickBooks Online. With that, I suggest sharing a proposal with our product engineering team. Here's how:
- Click the Gear icon.
- Under PROFILE, select Feedback.
- Enter a few words to describe your suggestion.
- Click Next.
As of now, you'll have to enter the customer's phone number on the field manually.
Moreover, you can check this article as your guide in recording customer payments: Take and process payments in QuickBooks Online with QuickBooks Payments.
