Hi @mitmarkbr,
I apologize for the delay in response.
The ‘Request Quote’ button text on the Checkout page can be modified using the below line of code present in the plugin.
../quotes-for-woocommerce/includes/class-qwc-gateway.php
Existing code on line number 21 is
$this->order_button_text = __( 'Request Quote', 'quote-wc' );
Modify the text ‘Request Quote’ to a text of your choice and save the file. Once done you should be able to see the updated text in the button on the Checkout page.
I hope this helps. Please let me know in case if you have any further queries.
Thanks,
Pinal
