Standard Odoo internal transfers move money between bank/cash journals (bank to bank). Our "Internal Transfer" payment type moves money within the same journal using Outstanding Receipts accounts, useful for recording internal fund movements, advances, or temporary transfers that don't involve actual bank transfers. It creates proper accounting entries without requiring two separate journals.

P2P allows you to record payments where money flows from one partner to another partner through your company. For example, if Customer A pays $500 that should go to Vendor B, you select Customer A as "Partner 1" (sender) and Vendor B as "Partner 2" (receiver). The system creates journal entries showing the cash flow through your Outstanding Receipts account while tracking both partners' balances.

The module uses two main accounts configured in your company settings:

Custom payment types (Internal Transfer and P2P) require you to manually enter an amount before confirming the payment. Unlike standard payments that can auto-calculate from invoices, custom types are standalone transactions, so you must fill in the "Amount" field before clicking "Confirm" to post the payment.

Yes! The module fully supports multi-currency payments. When you select a different currency in the payment form, the system automatically handles currency conversion using Odoo's exchange rates. Journal entries will show both amount_currency (original currency amount) and debit/credit (converted to company currency), maintaining proper foreign exchange accounting.
