Quickbooks Commerce Receiving Inventory, Bill Pay, Accounts Payable

Thanks for becoming part of the Community, vincehuen.
 

Once your vendor accepts the purchase order, you can manually add it to an expense, bill, or check.
 

Here's how:

1. In your left navigation bar, use the + New button, then choose Expense, Check, or Bill.
2. From your Payee ▼ drop-down list, specify the vendor. This will open a window with their open purchase orders.
3. Locate the appropriate purchase order, then click its Add option. This will add the items from your purchase order. They'll appear in the Item details section.
4. If you plan to bill a customer for a specific item, tick your Billable checkbox and add the customer you're planning to bill in your Customer column.
5. Select Save and close.

I can certainly understand how an ability to automatically apply payments to purchase orders could be useful and have submitted a suggestion about it as of today.

Is there any way this can be integrated with Quickbooks Commerce?  It seems like this manual entry of matching PO with a paid check can be a full-time bookkeeping job, especially if we deal with hundreds of purchase orders a week.

I can see the importance of having the option you're looking for is beneficial to your business, @vincehuen.

A purchase order is a non-posting transaction in which you need to create a bill first to make a payment. 

Right now, we don't have a specific timeframe when the option to automatically apply payments to purchase orders will be made available. For now, I suggest considering looking for a third-party app where you'll find applications that integrate with the software.

To view a wide range of options, use specific keywords to narrow down the search. You can check the reviews from other customers to help you decide which app suits your business type and needs.

To look for an app, here's how:

1. On your QBO account, click Apps in the left menu. 
2. Go to the Finds Apps tab.
3. In the search tab, type in the app you're looking for.
