When to Use This Template

  • As soon as you realize a deadline will be missed — before the client discovers it themselves
  • When external dependencies (vendor delays, API issues, third-party approvals) are pushing the timeline
  • After an internal review reveals that the current pace won't meet the original delivery date
  • When scope additions from the client have impacted the timeline but a formal scope change hasn't been discussed yet

Common Mistakes to Avoid

Waiting until the deadline has already passed to communicate the delay: Late notification destroys trust faster than the delay itself. Clients can adjust their plans if warned early — but they can't recover from being blindsided. Always communicate before the due date, not after.
Being vague about the new timeline: Saying 'we need more time' without a specific revised date leaves the client unable to plan. Even if you're not 100% certain, provide your best estimate and commit to updating them if it changes.
Over-explaining technical reasons the client doesn't need to know: A paragraph about server migration issues or dependency conflicts doesn't reassure the client — it overwhelms them. Keep the reason brief and focus on the recovery plan and what they can expect next.

Frequently Asked Questions

Should I offer a discount or compensation when a project is delayed?

Not automatically. Most clients care more about transparency and a solid recovery plan than a discount. If the delay is significant and caused entirely by your team, offering a goodwill gesture can help — but lead with accountability and a revised plan first.

How often should I send updates during a delay?

More frequently than during normal project flow. Weekly updates are the minimum during a delay — daily updates may be appropriate for short, critical delays. The goal is to prevent the client from having to chase you for information.
