Variable quantity in contract recurrent invoicing

With this module, you will be able to define in recurring contracts some
lines with variable quantity according to a provided formula.


#. Go to Invoicing > Configuration > Contracts > Formulas (quantity).
#. Define any formula based on Python code that stores at some moment a
float/integer value of the quantity to invoice in the variable 'result'.

You can use these variables to compute your formula:

* *env*: Environment variable for getting other models.
* *context*: Current context dictionary.
* *user*: Current user.
* *line*: Contract recurring invoice line that triggers this formula.
* *contract*: Contract whose line belongs to.
* *invoice*: Invoice (header) being created.
