+This module allows users to update the currency manually for invoices that are still in the draft stage.
+It offers flexibility to companies when calculating currency rates for invoicing.
+
+For example, if a company makes a deal with a vendor but the actual purchase happens on a different day,
+this module lets them choose whether to use the currency rate from the accounting date
+or a special rate agreed upon during the deal.
+This ensures accurate currency rate calculations for invoices,
+even when the purchase date and deal date differ.

+
+Usage
+=====
+
+To use this module, the company must have access rights for multiple currencies.
+
+Follow these steps to use manual currency:
+
+#. Go to Invoicing > Create new invoice/bills.
+#. If you need to change the currency to one other than the company's default currency, you will see an option for 'Manual Currency'.
+#. Check the 'Manual Currency' box to enable manual currency entry.
+#. Specify the desired currency rate for the selected currency.
