How does the invoicing work, and how is the commission calculated, for deals that don't involve a flat fee?

For “performance-based” deals, the 10% commission will be calculated based on the Buyer’s performance reports, which they are mandated to supply to both you the Seller and Vuulr.

Vuulr will invoice also according to the reporting frequency throughout the license period.

For any Seller’s first deal on Vuulr, we will also issue a US$1 invoice in order to establish an accounting relationship for future billing.
