Invoice number generation

The system generates a unique sequential number for each property. The Tax Invoice Start Sequence Number parameter which is set when a property is installed, indicates the starting invoice sequence number. If you do not specify a value for the Tax Invoice Start Sequence Number parameter, the system cannot generate tax invoices. You can re-set the value of this parameter, in which case, the next invoice generated starts from the new value. Invoices with duplicate invoice numbers are never printed. If the next tax invoice number is already used, the system generates an error message. You must set the following parameters, when you install a property, to facilitate invoice generation:

Name	Type	Valid Values	Default
Tax Invoice Start Sequence Number	Positive Integer	Not Applicable	Not Applicable
Tax Invoice Pay By Days	Positive Integer	Not Applicable	1
Tax Id	Positive Integer	Not Applicable
VAT Id	Positive Integer	Not Applicable
