This tab serves as a place where you can generate new invoices for supplied services, work with already issued invoices, print them out and export them to accounting programs.



By clicking on Generate new invoices for the month ... for ..., you can bulk generate invoices for supplied services. If you have set up only one invoice group, you immediately get the option of generating new invoices for the current invoicing period. If you have set up more than one invoice group, it is first necessary to choose a concrete invoice group. Afterwards, you can see its description along with the option of generating invoices for this group.


Before you confirm that you want to generate invoices, enter the following details:


  • Opening invoice number / SS, or Opening VS: By this number you set a numerical series for a given invoice group. If you enter 2016000001 as the opening number of a series, then this number is assigned to the first invoice. Whenever a new invoice is issued, its number is the number of the last invoice increased by 1. The system always offers the highest invoice number in a given invoice group. Each invoice group has its own numerical series. No two groups has the same one. The maximum recommended length of an invoice number is 10 characters. This recommendation stems from the fact that banks and business applications usually expect that the variable or specific symbol on an invoice has a maximum of 10 characters. More about invoice numbering can be found on the following pages: How to set invoice numbering and Change of numerical series for invoicing.
  • Issue date: The date that will appear on an invoice as Issue date. Default: the first day of the month for which invoices are issued.
  • Taxable date: The date that will appear on an invoice as Taxable date. Default: the first day of the month for which invoices are issued.


Once invoice generation is successfully completed, the system automatically offers the next month. However, if you need, for some reason, to generate invoices for a different month, you can change the setting in InvoicingSettingsInvoice group. When editing a given invoice group, modify the Accounting period item.


Apart from the invoice generation option, this page also provides an overview of invoices issued for individual invoicing periods. You can choose which year and which type of invoices is to be displayed (Invoices, Proform invoices, All invoices). More about proforma invoices here.

All issued invoices can be exported to commonly used accounting programs. You can choose your accounting program in InvoicingSettingsGeneral by entering the relevant numerical value in the Export item. If you do no want to use invoice export, set the value to “0”. If you do that, there will be no export icon available for generated invoices. When you hover over the accounting program icon, a description appears informing you of export type and the date when invoices were last exported. If invoices have not yet been exported to the accounting program, a text appears saying Not sent yet. If the accounting program icon is full colour, it means that given invoices have not been exported yet. If the accounting program icon is greyed-out, it means that given invoices have already been exported. Once you click on the icon, you are redirected to a page with invoice export options. No matter which type of export you have chosen, a list will appear of all clients with an overview of specific and variable symbols used.
More information on the possibilities of invoice export can be found here:

When exporting invoices, you can choose:
