+# dlv_account_reconciliation_rest_amount
+
+## Overview
+
+`dlv_account_reconciliation_rest_amount` extends the standard bank
+reconciliation screen (Accounting → Reconciliation) so the still-open
+("rest") amount of a line is shown in parentheses next to its total.
+
+On the reconciliation screen, when a proposed line (the bank movement itself,
+or an added invoice/bill) is only partially used to close the statement line,
+Odoo shows the full amount struck through and the partial amount used above
+it — but not what remains unmatched on that line. This addon adds that
+missing number, e.g.:
+
+```
+€ 1.899,97
+€ 4.486,35   (€ 2.586,38)
+```
+
+so the user immediately sees that €2.586,38 of that invoice is still
+outstanding, without having to search for it elsewhere.
+
+## How it works
+
+- `static/src/js/reconciliation_rest_amount.js` patches
+  `account.ReconciliationRenderer`'s `ManualLineRenderer.update()`. Before
+  every render, it walks `state.reconciliation_proposition` and, for any line
+  where `partial_amount` differs from `amount`, computes and formats the
+  difference as `line.rest_amount_str`.
+- `static/src/xml/reconciliation_rest_amount.xml` inherits the shared
+  `reconciliation.line.mv_line.amount` template (from `account_accountant`)
+  via xpath and prints `line.rest_amount_str` between parentheses, right
+  after the existing amount.
+
+Because both the bank movement (liquidity line) and any added invoice/bill
+proposition are rendered through the same loop and template, this single
+patch covers both cases.
+
+## Dependencies
+
+- `account_accountant`
+
+## Installation
+
+Standard addon install/update. No configuration or data is added; the change
+is purely visual on the existing reconciliation widget.
