To make customized Invoices to bill customers for incoming calls through our PBX and Credit Notes to pay telephone agents for time worked.
We make and supply the background images for the LibreOffice Calc Spreadsheets. We use a small spreadsheet with background image for the "center part" of an invoice-template and an interchangeable "top" and "bottom" part on the same page, to make up the complete Invoice-Template. The client only sees the whole Template, he doesn't see the spreadsheet !
