Hi,

By account groups, we can reorder the chart of accounts in odoo. You can follow below steps:

1. Activate developer mode.

2. Accounting-> Configuration -> Account groups

3. Create a new account group with a code prefix,from: 1100 to: 1102 or keep as empty to take an infinity count.

Regards

You can renumber the accounts if you wish.  It should not cause any problems.

After you save this, the accounts will be sorted in sequence.

You can also use account groups to summarize.

This is a helpful walkthrough for getting accounting accounts set up in Odoo. Turning on developer mode and organizing accounts through the Chart of Accounts makes the whole process much clearer, especially when you're trying to keep everything structured for reporting. Setting the right account types up front also saves a lot of cleanup later.

To set up accounting accounts, go to Settings → Chart of Accounts → Create, then define each account by selecting its Type (Asset, Liability, Income, or Expense) and giving it a clear Name. Make sure each account aligns with your business workflow—like linking income accounts to products and expense accounts to vendors.

At Ledger Labs, we usually recommend setting up a clean, structured chart early on—it makes reporting, reconciliation, and audits much smoother down the line.
