Client scripts for Zoho Books ?

Client scripts for Zoho Books ?

Good day everyone,

I am looking for a way to be able to interact with the Quotes and Invoices as they are being created. Think of it like Zoho client script in Zoho CRM.

But for the life of me I dont see a way to do this. The issue with having function run after a Quote is created is that sometime people are to fast and send the Quote right away. 

We can't use validation rules as those field will be empty and would not allow to save until the script is ran but the script will never run because the Quote is never saved.

I saw in this post that they where able with a plug in to make real time injection. I was just not able to see how to achieve this. : https://help.zoho.com/portal/en/community/topic/calculations-in-item-custom-field

Any idea how I could prevent people from sending the email or accept the quote until the script as run?

Thanks
