Has anyone had the issue if you send the invoice for payment and you have client a credit memo they are not able to add tip on the rest of the invoice that is due?

I'm here to implement a workaround so your customers can add tips to the invoices tied with a credit memo and provide clarifications regarding this, Brgalliher.

Customers can't add a Tip if the invoice they're trying to pay is associated with a credit memo. That's why the Tip field is not visible on the Preview and pay page.

Moving forward, if you're sending an invoice linked to a credit memo, you may coordinate with your client to add the tip as an item line when you send them an invoice. This way, you can add the tip value to the total amount of the customer's invoice.

If you want to follow this path, here are the steps to add the tip as a service item:

1. Go to the Gear icon and select Product and services.
2. Click New and pick Service or Non-inventory.
3. You may enter "Tip" as the item's Name and add a Description if needed.
4. Choose an account from the Income account dropdown.
5. If the tip doesn't have a fixed amount, you may leave it blank. Then, manually modify it once you add this item to an invoice.
6. Double-check everything, and once done, hit Save and close.
