Can i make delivery note to Customer and how can i receive the materials from the suppliers?

Yes, you can, @wael3.

Let's go to the Sales menu and create a delivery note from there. I'd be glad to guide you how in your QuickBooks Online (QBO) account.

Here's how:

1. Go to the Sales menu.
2. Click the Customers tab.
3. Select the customer's name to display a list of their transactions.
4. Click the Transaction List tab, select the box next to each invoice or sales receipt for which you want to print a Delivery Note.
5. Select the Batch actions drop-down, then choose Print delivery note. 
6. The print preview screen will open so you can select printing options, preview, and print.

Then, make a payment to receive the materials from your supplier. Ensure you've created a bill first to apply the payment. Here's an article you can read that provides detailed information on how to create and pay bills in your QBO account.

On top of this, I encourage checking these great resources that can guide you in managing your income and expenses accordingly.
