Hi,

You can inherit account report as follows:

<template id="report_invoice_document" inherit_id="account.report_invoice_document">
      <xpath expr="//div[@class='page']/h2[1]" position="after">
            <div class="col-4">
                <img t-if="o.l10n_sa_qr_code_str"
                     style="display:block;margin:10% auto 0 auto;"
                     t-att-src="'/report/barcode/?type=%s&amp;value=%s&amp;width=%s&amp;height=%s'%('QR', o.l10n_sa_qr_code_str, 150, 150)"/>
            </div>
    </xpath>
</template>
