Transfer accounts to a next new year

Dear Sir,

can in know at the end of the current year and all data inserted and reconciled correctly,

My question is how I let the program transfer all the accounts balances as appeared in the current year to the next new year ?

You don’t
Manager is a continuous accounting package, so you add next years data to the same Manager business as last year.
To close an accounting period see these guides
Close an accounting period | Set lock date

thank you very much, well noted
