Purchase Invoices from A Prior Date

It seems like that whenever I enter a purchase invoice into Manager, if the date inputted is not today, but yesterday or some other prior date, the inventory will always show up as “0”
Is there a way around this? Is there a reason why it is set up like this?

Have you set opening balances? If you are using Opening balances module, then any transaction entered prior the opening balance date won’t be taken into the account.

So the first question, is this brand new business you are setting up on Manager or are you migrating existing business to Manager?
