Help me explain estimates versus fixed prices clearly to customers.

My business: [what you do]
When I give estimates: [e.g. when I can't see inside the wall]
When I can fix a price: [details]
What can make costs change: [list]
How I tell customers when costs change: [e.g. call before going over]

If something essential is missing, ask me 1 or 2 short questions first. Wait for my answers.

Then:
1. A plain explanation of the difference, in 3 or 4 sentences.
2. Wording for estimates and for fixed-price quotes.
3. A script for when an estimate is going to be exceeded.
4. A line to say when handing over an estimate.

Clear and honest. Not legal advice. UK English.
