Steps to Create an Internal Cash Transfer in Odoo 18:

1. Go to the Accounting Module:
   • From the Odoo dashboard, click on the Accounting module to open the accounting interface.
2. Navigate to the Cash/Bank Menu:
   • In the Accounting module, go to the Operations menu, and then select Transfers.
3. Create a New Transfer:
   • Click on the Create button to start a new internal transfer.
4. Fill in the Transfer Details:
   • Transfer Type: Make sure to select Internal Transfer from the available options.
   • From Account: Choose the source cash or bank account (i.e., the account from which you are transferring funds).
   • To Account: Select the destination cash or bank account (i.e., the account where you are transferring funds to).
   • Amount: Enter the amount of money you wish to transfer.
   • Currency: Make sure to select the correct currency for the transaction (this will default to the currency of the source account if the transfer is internal within the same company).
5. Set the Date:
   • The transfer date will default to today, but you can manually change it if needed.
6. Validate the Transfer:
   • Once you’ve filled in the necessary information, you can either click Save to keep the transfer as a draft or Validate to confirm the transfer.
   • If you validate the transfer, Odoo will create accounting entries for the internal transfer, moving the funds from one account to another.
7. Check the Transfer:
   • After validating the transfer, the system will automatically create journal entries that reflect the change in the balance of both accounts involved in the internal transfer. You can view these entries in the Journal Entries under the Accounting menu.

Important Notes:

• Internal Transfer vs. Payment: Internal cash transfers in Odoo 18 are specifically for transferring money between accounts within your company (e.g., between different bank accounts or between a bank and a cash account). This is different from making a payment to an external party or a vendor, which involves a different workflow.
• Currency Considerations: If you're transferring funds between accounts with different currencies, Odoo will apply the exchange rate and show the gain or loss in the corresponding journal entry.

Summary:

To create an internal cash transfer in Odoo 18, go to the Accounting > Operations > Transfers menu, select Internal Transfer, choose the source and destination accounts, input the transfer amount, and validate the transaction. This will update both accounts and generate the necessary journal entries for the transfer
