Billing question
Example - we sell a client annual 365 licences e.g. business standard, so the contract group has a start date, and the product line has the same start date. Mid way through, they add a different 365 SKU, e.g. Basic, that we co-term with the existing standard licences. How do I add that to Gorelo for it to create me a pro-rata invoice for the mid term start date to the renewal date of the existing licences? If I add the product line start date of the date it was added, Gorelo wants to invoice 12 months from that start date, not a pro rata amount.
