If you want to change the chart of accounts in use, it should be noted that comparative figures must be presented in the financial statements for the ended and previous financial year. The same account cannot be used under different names in different financial periods. When changing the chart of accounts, consideration must be given to how to handle the balances of those accounts that are not found in the new chart of accounts, i.e., whether they will be transferred to the desired accounts with a memo voucher. The change of the chart of accounts must also be made on the Sales Invoices and Purchase Invoices side if those applications are in use.
Purchase Invoices
If default accounting assignments have been saved behind the suppliers, they should be removed or corrected if necessary. Purchase invoices that have not been transferred to accounting must be re-accounted if the new chart of accounts' accounts are to be used on the invoices.
Sales Invoices
On the Sales Invoices side, it is possible to correct the accounting account for completed sales invoices. If the invoices have already been sent and transferred to accounting, correcting the account is easiest to do either directly on the accounting vouchers or by correcting the balances with a memo voucher.
