The Invoices sub-module allows you to view all your customer invoices as well as carry out payments or supplies on already created invoice.

The 'S' and 'P' at the end of the invoice row simply means supplied and paid respectively.

When the 'S' is colored red it means the items on the invoice have not yet been supplied, when it is colored green it means the items have been supplied. This same rule applies for the letter 'P'.

When the 'P' is colored red it means the item has not been paid for, but when it is colored green, it means the item has been paid for.
