2. Enable Payment on Account payment method.

3. Create 2 simple products.

4. Create a company account.

5. Add company credits exceeding the total price of 2 products created.

6. Login to the frontend using the company account created.

7. Add the 2 products created to the cart, and checkout using the Payment on Account payment method.

8. Try to create a partial invoice for the order created via REST API:

   POST /rest/V1/order//invoice
   {
     "items": [
       {
         "order_item_id": 2,
         "qty": 1
       }
     ]
   }
