Hi @erserpico,

Make the VAT field mandatory if the Company field is filled in PrestaShop 1.7.8.8.

• Goto controllers/front/AddressController.php file and find the postProcess() function which is responsible for handling the form submission and validation.
• Modify the validation rules to check if the Company field is filled, and if it is, require the VAT field to also be filled.

The code should be something like,

if (Tools::isSubmit('submitAddress')) {
    $company = Tools::getValue('company');
    $vat_number = Tools::getValue('vat_number');
    if (!empty($company) && empty($vat_number)) {
        $this->errors[] = $this->module->l('Please enter a valid VAT number');
    } elseif ($vat_number && !Tools::isVAT($vat_number)) {
        $this->errors[] = $this->module->l('Invalid VAT number');
    }
}

Okay, Do you have any custom module?
