Anyone else with multiple billing platforms such as Recurly, AWS, Azure, etc.? And with revenue recognition rule that does not coincide with billing? Our contracts are mostly subscriptions and are based on usage. At the moment, we just import the invoices from the third-party billing plantforms and manually post a revenue journal. What is the best way to handle this in NS? Do you use the SO-Item Fulfillment-Invoice + ARM? Do you just import standalone invoices + custom usage data + ARM? Or does this require SuiteBilling? Or third-party alternatives like ZAB?
