As an administrator, you can ask Vinosmith to generate a report for each Sales Rep containing their Open Accounts (accounts with open invoices) and email it to them.
This will enable your Sales Reps to take active measures to get the Account paid-up.
To activate this feature, you must first edit the Supplier and activate Account Receivable Notifications.
Once you do this, you can initiate the report generation and emailing by:
Click on the Orders tab
In the left click on Accounts Receivable - Manage link
Click on the Payments: Applied tab
From the left hand navigation, click Manage Import Payment Batches
Then click on Notifications - Initiate
You'll then be shown which Suppliers are included in the A/R notifications
That is it. All of your sales reps with open Accounts will be sent an email with a PDF report.
