I used to have a link that would connect my bills to my purchase order and my purchase orders to my bills. With the last update I can only go from my bill to my purchase order. The link from my purchase orders to my bills is gone.
You can attach your Bill to Purchase Orders (PO) and then include this to your invoice.
To enable Billable Expenses
Go to the Gear icon (⚙) and selecting Account and Settings.
Navigate to the Expenses tab and click the Bills and Expenses section.
Check the box to Make expenses and items billable and fill out the settings that appear below.
Click Save and then Done.
Doing this will add a Billable column to all expense transactions so they can be carried forward into an invoice and sent to your customers. Now, assuming you've already created the purchase order, attach it to a bill like so.

If these billed items will be included on a customer invoice, check the box under the Billable column and select a name under Customer.
Click Save and close.
This will ensure you record and receive the items you're purchasing on the PO. Lastly, add these billable items to a customer invoice with the instructions below:
