Importing vendors invoices (goods) or purchase orders in QBO

Hello community,

I'm using QBO Plus with FIFO inventory tracking and I'm looking for a solution for the next scenario:

Each 2-3 months I need to enter to QBO a new vendor's invoice for 500-600 products (a half of existing products and another half is new products).

As I see, the typical solution by QBO is creating a purchase order (for inventory control) and vendor bill (for money tracking). Am I correct?

If I follow this solution, I can import a list of new products and create a purchase order manually. However, doing it manually I spent a lot of time and have a big chance for mistakes.

If I change number of products directly in stock manually, I loose opportunity to track inventory by FIFO and have a chance for mistakes again.

So, the question is:

Is there any way to import vendor's invoices (_not_ bills) OR purchase orders to QBO, as I can import initial inventory?

Thank you.
