+# Account Shared Bank Cash
+
+## Overview
+This custom Odoo 19 module removes the standard restriction that prevents Chart of Accounts (COA) of type **Bank and Cash** (`asset_cash`) from being shared across multiple companies. 
+
+By default, Odoo restricts a Bank and Cash account to a single company. This module patches `_check_company_consistency` on the `account.account` model to allow you to configure multiple companies for a single Bank/Cash account. This is particularly useful for setups where multiple Point of Sale (POS) shops across different companies deposit into the same physical bank account or cash account.
+
+## Features
+- Overrides `account.account` company validation to allow `len(company_ids) > 1` on `asset_cash` accounts.
+- Ensures POS payments and closing entries seamlessly use the shared account.
+
+> **Warning:** While POS and other payments will post to the shared account flawlessly, Odoo's standard Bank Statement Reconciliation strictly requires that statements and journal lines belong to the exact same company. Therefore, you cannot perform cross-company bank reconciliation natively in a single screen.
