1. Add milestone payment structure to all contracts: 50% at contract signature, 30% at primary intermediate deliverable, 20% at final delivery — define what constitutes each phase and its value weight before work begins
2. Add a project pause clause: "If the project is paused for more than 30 days due to client unavailability or internal delays, a restart fee of 20% of the remaining project value applies upon resumption"
3. Add a kill fee clause: "In the event of client-initiated termination, payment is due for all completed phases at the phase rates specified above, payable within 14 days of termination notice"
4. For larger organizational clients, specify in writing who has authority to pause or cancel the project — this prevents abandonment-by-ambiguity situations
