-- Spell out that the legal venue you've chosen for resolving disputes is sole and exclusive. If the words "sole and exclusive" don't appear in a contract with an Israeli provider, for example, then Israeli law requires that the case be tried in Israel.

-- Demand a performance bond in the contract, where a third party guarantees a vendor's performance. If the vendor doesn't meet its performance requirements, then you collect on the bond as you would on an insurance policy.
