From Abelujo you can:
If you'd like to send a text message to the client's phone, contact us. It is possible but the service is a bit expensive, so we can't include it by default.
A click on "OK" will remove one copy from the stock. We consider you put one copy aside, waiting to sell it for the client.
When you sell a book for a client, Abelujo will recognize it was reserved, and it will archive the reservation.
We can develop your website so that it accepts online payments. In that case, the commands will also show up here, with more information (was it paid online? Does it need to be shipped? etc).
