Invoice Budgets Sales invoice Deferred chargesWhich of this is a non-posting operation?

Thank you for reaching out to us, Ber-Bay. When you say non-posting transaction, this is recorded in the system for reference or planning purposes but does not affect accounts or balances in the general ledger. 
 
Budgets are typically considered non-posting transactions since these are planning tools and are not tied directly to financial transactions.
 
Deferred Charges can also be considered a non-posting transaction because they represent expenses or costs that are recorded for future recognition and don't immediately impact the ledger at the time of creation.
 
On the other hand, a sales invoice can be considered a posting transaction, as it affects both accounts receivable and revenue. While a general invoice may be posting or non-posting, depending on its status. Once finalized, it becomes a posting transaction.
