Confirm Quote Changes by Email (Stop WhatsApp Scope Creep)

WhatsApp is fine for chat. It is a weak place to renegotiate price and scope. Move every material change into one short email so both of you have the same numbers before work starts.

Free template: confirm revised quote in writing

Send after a WhatsApp (or call) change request. Replace every [bracket] before sending.

Hi [Client Name],

Quick written confirmation of what we discussed on [WhatsApp / call] today:

• Scope: [Revised deliverables]
• Price: [New Amount] (was [Old Amount])
• Timeline: [New date or range]
• Deposit to start: [Deposit Amount] due by [Date]

If this matches, reply “confirmed” (or sign the updated quote attached) and I will start after the deposit clears.

Thanks,
[Your Name]
[Your Business]

Why this protects both of you

• AP and stakeholders rarely see WhatsApp threads when invoices arrive.
• Memory of “what we agreed” drifts fast when chats keep mutating.
• A written confirm makes later “that wasn’t included” arguments shorter.

Simple rule

1. Chat is for questions and scheduling.
2. Email (or signed quote) is for scope, price, and dates.
3. No deposit / no start on revised work until the confirm lands.

What not to do

• Do not start the new scope from a thumbs-up emoji alone.
• Do not bury price changes in a long chat scroll.
• Do not invoice the old number after they already asked for more work.
