Start date not showing

I have updated version
Start date option not showing under settings
Any changes ?

A start date is not needed any longer. This was covered by an article in the recent edition of the newsletter. It was announced in the forum: Start date no longer required. It’s only purpose was to allow you to set starting balances. The procedures for that are now simpler. You can read about that in the Guide: Enter starting balances | Manager.

Ok then how to add opening balance for customer and supplier please guide me

As I told you would happen, the Guides were updated yesterday.
