6 Differences Between a Quote and an Estimate

The two words are used interchangeably in conversation and mean different things in a contract, which matters when the final bill arrives.
1. The distinction
A quotation is a fixed price offer. Once accepted, it generally forms a binding contract at that figure.
An estimate is an approximation based on the information available. The final cost can differ.
Which one you have depends on substance rather than the word used, though the word is evidence of intention.
2. What a proper quotation contains
The precise scope of work, itemised.
What is explicitly excluded, which is where most disputes originate.
The total price and whether tax is included.
Validity period, since prices for materials move.
Payment terms and stage payments.
Start date and expected duration.
3. When an estimate is reasonable
Where the scope genuinely cannot be known until work begins — opening up a wall, floor or drainage.
In those cases, ask for a fixed price on the known elements and an hourly rate plus a cap on the unknowns.
Ask to be notified and to authorise before any additional cost is incurred, and put that in writing.
4. Variations
Changes requested during the work are the main cause of budget overrun.
Agree in advance how variations will be priced and recorded.
Confirm each one in writing at the time, however informally, since memories differ later.
5. If the final bill exceeds the quote
Where you had a quotation and the scope did not change, the original figure generally stands.
Where you had an estimate, the price must still be reasonable, and unexplained large increases can be challenged.
Ask for a breakdown showing exactly what changed and why.
Pay the undisputed portion and raise the disputed part in writing through the trader's complaints process.
6. Practical protection
Get everything in writing, including verbal assurances.
Keep all correspondence, photographs and receipts.
Paying part by credit card can provide additional protection in some jurisdictions.
Final Thoughts
The two words are used interchangeably in conversation and mean different things in a contract. Get the scope, the exclusions and the pricing model in writing before anyone starts work.
