With Odoo16, introduced a new accounting feature Storno Accounting. Storno accounting
                            can be defined as the process of reversing original journal account entries by adopting
                            negative figures. This business practice of Storno Accounting is commonly used in
                            Eastern European countries. Some countries where Storno Accounting is mandatory
                            includes:
                        
                            - Bosnia and Herzegovina
- China
- Czech Republic
- Croatia
- Poland
- Romania
- Russia
- Serbia
- Slovakia
- Slovenia
- Ukraine
                            They consider Storno Accounting is the best practice to reverse journal entries
                            with negative debits and credit which will not create redundant figures in the accounting
                            system. The reversal can be for various reasons such as when any mistakes happen
                            in the original transaction or in case the return of items refund has to be added
                            etc. This accounting technique is also known as Red Storno since bookkeepers frequently
                            write Storno entries in red ink. All such entries will be available in the accounting
                            reports as red color.
                        
                        
                            To avail of these features enable ‘Storno Accounting’ from the Configuration Settings
                            of the Odoo 16 Accounting Module.
                        
                             
                        
                        
                            In general, when a transaction occurs, let's say an invoice is created which will
                            affect some ledger accounts. Usually, for an invoice, the Income Accounts get credited
                            and Account Receivable gets debited. If this transaction is reversed, what will
                            happen is that the Income Account will get debited, and Account Receivable will
                            be debited. But for Storno accounting for the reverse entry, Income Account will
                            be ‘-ve‘ Credit, and Account Receivable will be ‘-ve’ Debit.
                        
                        
                            Consider an Invoice that has been added as shown below screenshot.
                        
                             
                        
                        
                            And for some reason, if this invoice is reversed and a credit note is created and
                            posted. Now let’s see the journal item and how each ledger is affected.
                        
                        
                             
                        
                        
                            For invoice, Income Account is Credited and Account Receivable is Debited, and on
                            the reverse invoice or credit note, the opposite entry created with Income Account
                            is Debited and Account Receivable is Credited.
                        
                        
                            On enabling Storno accounting, for reversed journal entries, the Debits and Credits
                            are in negative figures. Create an invoice and credit note respectively for the
                            invoice. Let’s see the ledger posting in Storno Accounting.
                        
                        
                            For invoices, initially, Income Account is credited, Tax Account is credited, and
                            Account Receivable is debited. On reversing journal entry for Income Account and
                            Tax Account is credited with a negative figure, and Account Receivable is debited
                            with a negative figure. In short, the below table shows the general ledger posting
                            and Storno ledger posting.

| Reverse Invoice | Income Account | 320 |  |  | -320 |
