Hi,

In Odoo, your printed invoice shows amounts in the company currency (IQD in your case) by default, because the QWeb report template uses amount_residual and amount_total without forcing a specific currency.

If all your customers are billed in USD but your company currency is IQD, you can still display the due amount in USD on the printed invoice by leveraging amount_residual_currency and currency_id.

Try the following

- Inherit the template in your custom module.

       <odoo>

    <template id="invoice_show_due_usd" inherit_id="account.report_invoice_document">

        <xpath expr="//span[@t-field='o.amount_residual']" position="after">

            <p t-if="o.currency_id.name != o.company_id.currency_id.name">

                <strong>Due Amount (in <t t-esc="o.currency_id.name"/>): </strong>

                <span t-field="o.amount_residual_currency"/>

            </p>

        </xpath>

    </template>

</odoo>

Hope it helps
