Billing Templates

To make customized Invoices to bill customers for incoming calls through our PBX and Credit Notes to pay telephone agents for time worked.

We use spreadsheets with background images to first make the templates. We make and supply these background images ourselves.

Before being uploaded to the server, the spreadsheets with background images, including all calculations between Cells, must be changed to pdf with open source software (like AstPP), without loosing anything,

Than they can be filled out on the Internet by our own clients, changed to pdf again and send by email, as invoices or Credit Notes, to their final destination. The client must never see the spreadsheet, he only sees the background image with the data he entered into the Cells !

Min. Requirements:

1) LibreOffice Calc Spreadsheets.

2) Software (open source) to change the spreadsheet files to pdf, without loosing calculations !

3) Open source Software to connect Asterisk to Cells on the spreadsheets.

N.B.: Server and Asterisk PBX are on different networks !

This is a none existing, none standard project and not for beginners !!

Very good knowledge of the way Spreadsheets, Billing software, Credit Notes and Asterisk PBX work, is needed. We have a Multi Disk Server with KVM disk management and MySQL DB ready to upload.

-- Good and quick communications are essential !

You must have a computer with a Linux OS --- This is not for Windows !!

Please read and understand the image-file attached to this project, for step by step instructions !

Project will be divided into 3 milestones.
