Scope Creep Email: Extra Work After the Project Started

Mid-project, the client asks for “just one more thing.” Before you build it, send a short change email: name what was agreed, name the new ask, give a price and timeline, and wait for a yes. That protects both of you and keeps invoices honest.

Hi [Client Name],

Wanted to lock this in writing before I start.

Original scope (from [Quote / SOW date]): [Original Scope Summary]

New ask: [Extra Work Description]

Estimate for the change: [Hours / flat fee] → [Amount], timeline impact [+X days / no change if we swap Y].

If that works, reply “approved” (or send a PO) and I will add it to the next invoice [Invoice timing]. If not, we stay with the original scope and ship [Original Deliverable] on [Date].

Thanks,
[Your Name]
[Your Business]

Why email this before you build

• Chat “sure” is easy to forget; an email creates a billing trail.
• It forces a clear approve / decline so you are not guessing.
• It separates goodwill help from unpaid scope growth.
• It keeps the next invoice from looking like a surprise.

If they say “can you just include it?”

• Offer a swap: drop [Item] to fit the new ask at the same price.
• Or keep both and bill the change order.
• Do not start the extra work until one path is confirmed.
