Follow-up plan + common mistakes

If they reply, confirm the new date in writing and enforce it strictly
If there is no reply, escalate your next step without offering endless new extensions
Don’t debate or argue old delays—focus only on resolution
Don’t give multiple untracked extensions—it hurts leverage
Don’t remove the pay link or invoice facts from your reminder

FAQ

Yes—reference both the original and extended dates, then focus on the new ask succinctly.
