Hi,

Add these fields by inheriting the account.move the model and extending the account.report_invoice_document template

Refer the following code

class AccountInvoiceInherit(models.Model):
    _inherit = "account.move"

    insurance_customer_id = fields.Many2one('res.partner',string='Insurance Customer')
    car_model = fields.Many2one('fleet.vehicle',string="Car Model")

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

    <xpath expr="//div[@class='page']" position="inside">

        <div t-if='o.partner_id'>

            <b>Insurance Company:</b>

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

        </div>

        <div t-if='o.insurance_customer_id'>

            <b>Insurance Customer:</b>

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

        </div>

        <div t-if='o.car_model'>

            <b>Car Model:</b>

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

        </div>

    </xpath>

</template>
