The default PayPal buttons says “Proceed to PayPal”. You may want to change this to something else like “Continue to Pay” or whatever you like.

You’ll need to use a child theme and paste the following into the functions.php file. You can find this in Appearance > Editor.

Change the YOUR NEW BUTTON TEXT to whatever you like.

add_filter( 'gettext', 'custom_paypal_button_text', 20, 3 );
function custom_paypal_button_text( $translated_text, $text, $domain ) {
	switch ( $translated_text ) {
		case 'Proceed to PayPal' :
			$translated_text = __( 'YOUR NEW BUTTON TEXT', 'woocommerce' );
			break;
	}
	return $translated_text;
}
