Good day, @HKS2019. Currently, QuickBooks Online doesn't allow you to add a packing list between PI and the invoice. I'll provide a detailed explanation below.
Since estimates are non-posting transactions, any inventory added in estimates will not decrease the original quantity of the inventory item, which is why QB can't determine what stocks are not for sale yet. You can convert the estimate into an invoice to ensure that the quantity on hand is decreased. However, this inventory is considered for purchase, even if payment has not yet been received.
You can explore the QuickBooks Online apps store for third-party applications that integrate with QBO to help you hold stocks until you're ready to sell them to the customer. Here's how:
- Click the Apps on the left navigation. Then, select Find apps.
- On the search bar, enter the keyword of the application you want to find.
- Pick the correct application.
Also, you can click this link to find one: QuickBooks Online Apps Store.
