Hi, nacho

Thanks for showing interest in Amelia.

- Our plugin is made to be used for fixed time slot bookings;

 we do have an "extra" section for Services, for example, where customers can extend the time of a slot...

But unfortunately, we don't have the facility to make bookings without any date or time, at this moment.

Perhaps we will add this feature in the future, i can't say an ETA on it.

Please feel free to search through our feature suggestion page, 

 to see if someone may be already suggested this feature. If you can't see it, feel free to add your suggestion there, and it will be forwarded to our management for review.

After it's been reviewed it will be presented on the front page, for voting. Please note that it may take some time before your suggestion is brought up for voting since we receive quite a lot of suggestions on daily basis, and as more people vote, the feature will move higher on the priority list.

You can certainly follow our changeLog page if you'd like, where we state any changes/new features/bug fixes during updates;

and our newsletter, so you're informed about new features, bug fixes, freebies, etc.

Additionally, I just wanted to point out that we have pages with Demos, that you can use to try out the plugin's features - https://wpamelia.com/demos/

and there is a 15-day money-back guarantee period,
so if you purchase the plugin, you can safely fully test it out,

we would assist you with our support along the way,
and if it doesn't fit your needs you can request and receive a refund in that period.

Let me know if you have any questions. Thanks
