Often happens during accounting audit that you have to randomly select invoices from those present in bookkeeping. With this tool you can randomly select an invoice number between a minimum and maximum numbering interval.
In the "minimum value of invoice numbering" field you could enter the starting number (for example 1) while in the "maximum value of invoice numbering" field you could enter the final number (for example 127 which can correspond to the last invoice issued at the end of the year).
