A customer can either manually post a VAT journal at the end of the period or they can have the system set so this journal is posted automatically.
If the customer would like the VAT journal set to automatically post at the end of the period the NL system parameters will need amending.
To navigate to the parameters from the Main Menu go;
Nominal Ledger (NL) - System Maintenance - System parameters
Once in here click on the EOD/Period tab.
The VAT Clearing Account field needs to be populated with the cost centre and expense code that the automatic journal should post to.
If this field if left blank then the journal has to be done manually.
