Quote acceptance link validity
Set accept quote link’s validity
Solution
As we know, you can include the {{quote.accept_quote_link}} in Quote Emails as a mail merge field.
In order to set their validity, you can -
Navigate to: Settings > Configure Chargebee > Invoices, Credit notes, and Quotes > Quotes
You can set the validity here (as shown in the below image)
Set the number of days > Apply > Apply Changes
Note: Validity can be up to a maximum of 30 days. Once the validity period has expired, quotes will be marked as Closed. The Accept Quote link in the quote email is valid for the same duration as the quote.
