As of ProStores v9.3.1 <http://www.prostores.com/newfeatures-931.html>
it is possible to add Invoice Notes to your Invoices which can be displayed
to your customers. However, this leaves out one important feature - Internal Notes.
This addon allows you to track internal notes which can be made visible to your
separate departments while remaining invisible to the customer. This establishes
a common location for notes to be maintained on a per-order basis.
Features include:
Public notes visible to your customers.
Allow your customers to respond on the same thread maintained on their invoice.
Email notifications to you when a customer responds.
Email notifications to the customer when you make a new public note to them.
Internal notes maintained in-line with the thread between the customer and yourself.
Color highlighting differentiates the note-type to you, so it's quickly obvious which notes are public versus internal.
You must have an account before you can install Addons. Sign up or sign in.
