Thank you for your question. It is possible to add booking manually however there is no option to send payment link or request payment automatically yet. However we are developing a new addon that would allow to request payments to pay full or rest of deposit. We’ll update this topic once it is released.
The feature that you requested is now available for MotoPress Hotel Booking. With the new addon Request Payment, you can accept bookings and send a payment request after you review and confirm the booking. You can read more about the plugin in this article. Thank you for all your suggestions!
