I have been facing following issues: 1. Supplier grouping not possible here 2. We cant take credit note print out if we want to send to our client

Let me share some information and help you address those concerns, paras2.

1. Supplier grouping not possible here.

Currently, the ability to create supplier groups in unavailable in QuickBooks Online. But I can see how this option would be helpful for you and your business. Rest assured that I'll take note of your suggestion and send it to our Product Developers.

2. We cant take credit note print out if we want to send to our client.

Credit note appears only on customer statements. That said, after you apply the credit note to an invoice, you should be able to print and sent it to your client. Let me show you how to apply a credit note.

Here's how:

1. Click on + New, then Receive payment.
2. In the Customer dropdown, choose the customer.
3. In the Outstanding Transactions section, select the open invoice you want to apply the credit note to.
4. In the Credits section, select the credit notes you want to apply. You will not be able to see the credits section if you haven't created the credit note.
5. For the open invoice in the Payment column, enter how much of the credit you want to apply.
6. Leave the Payment method, Reference no, Deposit to, and Amount received fields blank.
7. Complete the necessary info in the form, including the Payment date.
8. Make sure the total is correct after applying the credit note.
9. Once done, select Save and close.

I'm adding this link to learn when the memo field will and will not print.

Get back to us if you still need further assistance. I'll be around if you need me. Have a good day!
