Hi, Plz check my char of accounts some problem we are facing (cost of sale) too many creat from my sales person plz help us. also we want dont creat invoice less inventy

I'm here to sort things out for you, @cttajlan.

If there are too many sales transactions created, you can delete them. Let me show you how: 

1. Sign in to your QuickBooks Online account.
2. Go to the Sales menu on the left panel.
3. Choose the Invoices tab.
4. Select the invoices you want to delete.
5. Under the ACTIONS column, click Delete.

For your second concern, if you mean to create an invoice to diminish the inventory, you can create an inventory item and apply the invoice after. 

Here's how: 

1. Go to Sales, and then select Products and Services.
2. Choose New and then select Inventory.
3. Add a Name, SKU, or category for what you're tracking.
4. Add your product’s Initial quantity on hand and then enter the period in the As of date field.
5. Choose the Inventory asset account ▼ drop-down and select Inventory Asset. 
6. Add your product’s description on sales forms. 
7. Select the Income account ▼ drop-down and find the account you use to track what you sell.
8. Add the product’s Cost.
9. From the Expense account ▼ drop-down, select Cost of Sales.
10. Select a preferred supplier and click Save and close once done.

If you mean other things, you can add some more details so I can provide other steps to fix this. 

I've also added this article than can guide you on how to track inventory: Set up and track inventory in QuickBooks Online.

I'll be around if you need anything else. Have a great day.
