Bill are wrongly posted some other Ledgers ?

Hi there, viswanathan.

We can correct the bill that was posted to the account by following these steps:

1. Go to Accounting on the left panel.
2. In the Chart of Account lists, select the account where the transaction is recorded.
3. Locate the bill and click. 
4. Select Edit.
5. Change the posting account, and click Save and close.
6. Hit Yes to confirm.
   

On the other hand, if you mean the items associated with the bill, we can update the account used in the item. Here's how:

1. Go to Sales on the left panel.
2. Within the Product and Services tab, find the item and click Edit under the Action column.
3. Change the account. Then, Save and close.
