Can I add on the credit card for the payment on my phone ?

Yes, you can process credit card payments on your phone using a third-party processor like PayPal, Stripe, or Square, @NIK HEATING AND COOLING.

These processors allow you to accept credit card payments anytime and you can connect them to QuickBooks Online to sync transactions automatically.

Here's how:

1. Go to the Apps section in QuickBooks Online.
2. Search for the payment processor you’re using (e.g., "PayPal" or "Stripe") in the search field.
3. Follow the prompts to connect the app to your QuickBooks account. After integration, payments processed through the third-party platform will sync into QuickBooks automatically.

For more details on accepting credit card payments,  you can check this resource: Accept Card Payments with PayPal App FAQ.

Alternatively, if you prefer not to use an integration, you can manually record the payment in QuickBooks after it’s processed through the third-party app. This keeps your books accurate and up-to-date.
