Quote vs Estimate: What Should You Send?

The practical difference between a quote and an estimate, when each is useful, and how to protect both you and your customer when the job changes.

Short answer: an estimate is your informed approximation of what the work may cost. A quote is a specific offer to complete a defined scope for a stated price and, once accepted, will usually become part of the agreement between you and the customer. Your written wording and the circumstances matter, so label the document accurately.

When an estimate makes sense

Use an estimate when a customer needs an early budget but important information is missing: drawings are not complete, finishes have not been chosen, hidden work cannot be inspected, or the job needs investigation first.

Explain what the estimate is based on, give a range where appropriate and list the decisions that could change it. Do not call a document an estimate merely because you have not taken enough time to price the job.

When to provide a quote

Provide a quote when the scope, specification and site conditions are clear enough to price. Include the work, price, VAT position, payment schedule, validity period, start assumptions, exclusions and what happens if the customer requests a change.

If the job contains uncertain elements, you can still quote the defined work and identify provisional sums or separately priced investigation. Clarity is better than hiding uncertainty inside one number.

What happens when the job changes?

Stop and document the change before carrying out extra work wherever practical. Describe the variation, state the additional price or pricing method, explain any programme impact and obtain written approval. A message or signed variation is far easier to rely on than two different memories at invoice time.

Important: changing the label at the top of a document does not override everything else it says. An accepted quote, messages, terms and later variations may all form part of the agreement. This guide is practical information, not legal advice for a particular dispute.

Five wording mistakes that create disputes

  1. “All work included” without a detailed scope.
  2. No exclusions for hidden damage, access or customer-supplied items.
  3. No validity period while material prices or availability may change.
  4. No variation process for extras requested on site.
  5. Calling a fixed figure an estimate while the rest of the document promises a complete job for that amount.

A simple decision

If you can define the job, inspect the risks and calculate the price, send a quote. If key information is genuinely missing, send a clearly labelled estimate with assumptions and next steps. When uncertainty is significant, price a survey or investigation first and quote the main work afterwards.
