CLIENT-READY CHANGE MESSAGE

Thanks for the additional request. It sits outside the agreed scope and adds approximately 6 hours of work. The added fee is $518.13, and the revised delivery timing is +2 business days. I’ll begin the extra work once the fee and timeline are approved in writing.

01DECISION FIRST

Classify the request before pricing it

A small request is not automatically included. Compare it with the accepted deliverables, exclusions, feedback process, and deadline. Classify it as one of three things:

  • Included: it completes an agreed deliverable within the included revision process.
  • Timeline change: it is included, but late feedback or a new dependency moves delivery.
  • New quote: it adds work, direction, urgency, formats, people, or responsibility.

02PRICE THE FULL EFFECT

Extra work is more than the visible task

Estimate production time plus the project-management, context-switching, approval, subcontractor, and schedule risk that genuinely applies. Use an internal hourly floor, then add the relevant overhead and risk before protecting profit and payment fees.

Added fee = ((hourly floor × extra hours) × (1 + overhead + risk)) ÷ (1 − profit) ÷ (1 − payment fee)

Do not add costs that do not exist, and do not present an estimate as a guarantee. The calculator provides a transparent starting point for your own judgement.

03GET WRITTEN APPROVAL

Pause the extra item, not the whole relationship

Send one short message stating what changed, the added fee, the revised date, and the approval needed. Continue the original agreed scope when practical. Begin the extra work only after approval is recorded.

Simple change-request structure

1. New request: what the client added or changed 2. Scope effect: work, responsibility, or deliverables added 3. Added fee: one clear number and currency 4. Timeline effect: revised delivery or milestone date 5. Approval: written acceptance before work begins

04中文快速說明

客戶臨時加工作，先確認再開工

先對照原本報價嘅交付內容、修改次數、排除項目同交期。如果新要求增加工時、格式、方向、負責範圍或急件風險，就應該列明附加費及新交期，取得書面確認之後先開始。

Common questions

What counts as a scope change?

A request may be a scope change when it adds deliverables, formats, stakeholders, meetings, revisions, responsibilities, urgency, or work beyond the accepted quote.

Should I charge only for the extra production hours?

Not always. Extra work can also add project management, schedule disruption, subcontractor cost, payment fees, and delivery risk. Price the complete effect that genuinely applies.

How should I tell the client about an added fee?

Keep it neutral: describe the new request, added fee, revised timing, and the written approval needed before work begins. Do not blame the client or start the extra work silently.

Are the figures stored?

No. The calculator runs in the browser and does not submit your rate, hours, fee, or message to this website.
