Hi,

    Choose Your Odoo Version

    Pick between Odoo Online (easy and hosted), Odoo.sh (flexible), or Community (free but needs setup).

    Install the Accounting App

    Go to Apps and install the Accounting/Invoicing module to get started with finance features.

    Set Fiscal Year to 2022

    In settings, allow posting from January 1, 2022, so you can enter your past records from when your agency started.

    Organize Your Past Transactions

    Go through your Google Sheet and group each cash inflow/outflow as income, expense, asset, etc.

    Choose a Chart of Accounts

    Select a default one for your country, or create simple categories like sales, software costs, office expenses, etc.

    Get Opening Balances Ready

    Write down your starting balances for bank, cash, any assets, and any money owed or owing as of your first 2022 entry.

    Plan How to Enter Data

    Decide if you'll type it in manually, import from a file, or get help from an accountant or Odoo expert.

Hope it helps.
