Hi there,
We don’t have anything ourselves at this time to do this. Having had a look online at other agents, I found this example:
https://www.hunters.com/rent/pay-online
They use a form from WorldPay which they’ve just dropped in. I suspect when you click the form it redirects off to WorldPay to handle the payment.
There is also a free ecommerce plugin for WordPress called WooCommerce which allows you to do something similar. Here’s their documentation:

Hope that helps and offers some options.
Regards,
Steve
