Structured exports are certainly better than nothing, but it doesn't address having to find and import to another system (which won't have all the same features) and retrain all staff.
Honestly this is a hard problem and something of a catch-22: the more useful the product is, the more it gets used, so the more critical it becomes, and as a result the pain goes higher.
A long track record of business, knowing if the company is profitable vs burning through VC cash, and some type of SLA and guarantee of minimum shut down notification time could all help lower risk. I don't really have any other product suggestions, unfortunately. My feeling is this is not really a technical problem and so probably doesn't have a purely technical solution.
