Hi, César ( @boutzero ).
Thanks for getting back to us.
I’m afraid that the plugin doesn’t have per stock qty customization options (e.g. display a different button when remaining stock qty is 1) – thanks asking about this! I love the idea and we would be keen to explore adding this in the future. I have added it to our feature request list so that we can track the amount of demand. We will let you know if we add this to a future version of the plugin.
In the meantime, I’m sorry that this isn’t possible.
As an alternative, you could add this as a customization. If you’re unfamiliar with this and don’t have a developer who can do this for you, then I recommend posting a job on Codeable where their pre-approved WordPress experts will send you a quote. We have partnered with them to provide plugin customization for our customers.
Codeable has several developers who are experienced in customizing our plugins – to request a quote from them, select Domagoj Kovacevic, Krasen Slavov, Onur Demir, Liam Bailey, Nitin Yawalkar and Felipe Elia as your preferred experts.
I hope this makes sense and helps point you in the right direction. Please let me know if you have any more questions.
Many thanks and stay safe,
