+# Payment Residual Display
+
+This module adds residual amount display to customer and vendor payments in Odoo 17.
+
+## Features
+
+- **Residual Amount Field**: Shows the unreconciled amount remaining on each payment
+- **List View Integration**: Adds "Residual" column to payment list views (hidden by default)
+- **Form View Integration**: Displays residual amount in payment form view
+- **Multi-Currency Support**: Handles both company currency and payment currency residuals
+
+## How It Works
+
+The module extends the `account.payment` model with a computed field that:
+
+1. Retrieves the journal entry lines created by the payment
+2. Identifies the counterpart lines (receivable/payable accounts) and write-off lines
+3. Sums up their `amount_residual` or `amount_residual_currency` values
+4. Displays the total unreconciled amount
+
+## Fields Added
+
+### `payment_residual`
+- **Type**: Monetary (computed)
+- **Currency**: Payment currency
+- **Purpose**: Shows the residual amount not yet reconciled
+- **Computation**: Based on `move_id.line_ids.amount_residual` and `amount_residual_currency`
+
+### `payment_residual_currency`
+- **Type**: Monetary (computed)
+- **Currency**: Payment currency
+- **Purpose**: Shows the residual amount in the payment's currency
+
+## Usage
+
+### In List View
+1. Go to **Accounting → Customers → Payments** (or **Vendors → Payments**)
+2. Click the column selector (☰ icon)
+3. Enable the "Residual" column
+4. You'll see the unreconciled amount for each payment
+
+### In Form View
+1. Open any customer or vendor payment
+2. The "Residual Amount" field appears after the payment amount
+3. Shows 0.00 for fully reconciled payments
+4. Shows the remaining amount for partially reconciled payments
+
+## Technical Details
+
+### Dependencies
+- `account` - Core Accounting module
+
+### Inheritance
+- Extends: `account.payment`
+- Views inherited:
+  - `account.view_account_payment_tree`
+  - `account.view_account_payment_form`
+
+### Computation Logic
+The residual is computed using the same approach as Odoo's built-in `is_reconciled` field:
+- Uses `_seek_for_lines()` to identify counterpart and write-off lines
+- Filters for reconcilable accounts
+- Sums the `amount_residual` or `amount_residual_currency` based on currency matching
+- This ensures consistency with Odoo's core reconciliation logic
+
+## Installation
+
+1. Copy the module to your Odoo addons directory
+2. Update the apps list
+3. Install "Payment Residual Display"
+4. No additional configuration needed
+
