From the start:
Before doing business with someone for the first time always credit check them, the same goes for existing customers wishing to increase their credit limit. If in doubt insist on payment up front; if their credit rating is poor they will understand and not be surprised by this.
If you are doing bespoke work or working on a project or product that cannot be sold to anyone other than that specific customer then ask for a deposit to cover basic costs. Make a point of discussing your Terms and Conditions. Ensure they are clearly stated and send them out with all confirmations and invoices...
