This article describes how to link a maintenance request to an invoice. You can then send the invoice through an approval workflow, and when the workflow is complete, the invoice will become a payable.
The procedure is divided into two parts:
Creating a maintenance request (MR), with billing information.
Creating an invoice and linking it to the MR, pulling in the billing information.
Note: This feature can only be used with Advanced Maintenance Requests.
To create a maintenance request with billing information
Go to Maintenance > Maintenance Requests.
Click the Add New button.
Complete the maintenance request as you normally would.
Assign the MR to a Vendor and a User.
Complete the Billing Info tab.
Do NOT post the maintenance request. If you click Post, Breeze creates a payable, not an invoice.
To create an invoice and link it to an MR
Go to Accounting > Accounts Payable > Invoices.
Click the Add New button.
Select the Payee.
Click the Add MR button.
The Choose MR screen appears.
Complete the filter.
In the example shown above, the Vendor is already filled in because we selected a vendor on the invoice. (If you did not select a vendor on the invoice, you can select one here.) Vendor is a mandatory field.
Complete any other filter items that are applicable.
Click Display. The screen shows MR line items that match your filter criteria.
Select the MR line item that you want to pull into the invoice.
Click Submit.
The MR becomes a line item on the invoice.
The wrench icon 
is a link back to the MR.
On the MR record, you can see the invoice on the Invoices tab.
To return to the invoice, click anywhere in the line item for the invoice.
Next Steps
Send the invoice through the approval process, as you normally would.
When the invoice is approved, Breeze creates a payable, and it appears on the MR, on the Payables tab.
When the MR is complete, you can post it to create the Admin Fee payable, if applicable.
Note: If you post the MR before the invoice is approved, the system will create a payable for the Admin Fee only (if selected). The payable for work or materials will not be posted until the invoice is approved.
