Spreedly operates a service to make the process of selling subscriptions easy, and they are themselves, it seems, very good at locking in customers. One example is the Spreedly Kickstart offer, where they capture revenue and lock in early customers by asking for a large payment up front to lock in lower ongoing costs.
The advantage for Spreedly is that they receive cash faster, while encouraging companies to commit to using the service rather than just running a trial. They will land bigger customers more easily (they see a deal) but will also capture excess revenue from companies that over-estimate their future transaction numbers.
Oh – and Speedly does not work for New Zealand companies. There seems to be a real gap in the market here for easy payment acceptance services for new companies.
