When you post an Invoice or transaction in a Customer's Account, you can leave one of these comments:
Public (meaning the customer can view the comment in the Customer Portal)
Private (meaning the comment is internal-only viewable by an Admin User)
There are multiple ways to do this:
Add Current Invoice
Go to a Customer's Billing page and under a Payment Plan, click on "Add Current Invoice:"
Under Step 3, you can add one of these comments:
On the Invoices page, click on "Edit" beside an Invoice.
Within the Invoice, click the three dots on any line item, then on "Edit."
Here you can add a Public or Private Comment:
Post Transactions Window
The Post Transaction Plus Button is the Plus button beside "Invoices" on the left sidebar menu.
Select any of the first four options:
A window will open where you can enter a charge, credit, or payment. Step 3 is where you can add a public or private comment to further describe the charge, credit, or payment.
Edit Existing Transaction
You can also edit an existing transaction and add a public or private comment. Follow these steps:
Click the three dots on any line item in the Transaction History, then select "Go to Invoice"
Once in the Invoice, click the three dots beside the transaction you want to add a comment to then select "Edit"
Add a comment then click Save
After adding public or private comments, you can easily see them in the Transaction History. Hovering over the private comment makes it more prominent so that it can be easily read.
