How do I add cash as a payment method for vendors?

Thanks for joining the Community, Gabby92.
 

You can add new payment methods for vendors by creating them in your Payment Method List.
 

Here's how:

1. In the top menu bar, go to Lists.
2. Move your cursor over Customer & Vendor Profile Lists.
3. Click Payment Method List.
4. Use the Payment Method ▼ drop-down list, then choose New.
5. Enter a title in your Payment Method field and pick Cash as its Payment Type.
6. Select OK.
   

I've additionally included a detailed resource about working with payment methods that may come in handy moving forward: Add or modify payment methods

Thanks ZackE!

Unfortunately I already tried that but when i go to pay the bill, it still only shows check or credit card, nothing else.

Steps to setup payment method works and the payment methods can be linked to customers. But not for vendors.

Is QuickBooks Enterprise capable of linking vendors to payment methods?

The payment method cannot be added to a Vendor under Payment Settings.

Hi there, @Vero7. Thanks for bringing this to our concern.

Currently, the option to link a vendor to a payment method is unavailable in QuickBooks Desktop. I can see the convenience of having this feature since it's essential to your company. With this, I would encourage you to send this product suggestion to our engineering team so they can incorporate this functionality into our upcoming updates.
