What Is a Business Quote?

A quote (also called an estimate, proposal, or tender) is a formal document that tells a prospective client what you will charge for a specific job. It is sent before work begins and, if accepted, forms the basis of your agreement.

A well-written quote builds trust, reduces scope creep, and gives both parties a clear record of what was agreed.

Step-by-Step: How to Write a Quote

Step 1: Understand the scope before quoting

Clarify exactly what the client wants before you write the quote. A discovery call or brief questionnaire prevents costly misunderstandings. Note any assumptions you're making — these belong in your quote's notes.

Step 2: Break the work into line items

List each deliverable or component separately. This makes the quote transparent and easy to review. It also helps if the client wants to reduce scope — they can see exactly what each item costs.

For example, instead of:

Website design — $3,500

Write:

Homepage design — $1,200 5 inner page designs — $1,500 Mobile responsiveness — $500 Revision rounds (x2) — $300

Step 3: Set a clear expiry date

Prices for labour and materials change. Protect yourself by stating how long your quote is valid — 30 days is standard. Write the expiry date explicitly rather than saying "valid for 30 days" (clients may not calculate the date themselves).

Step 4: State your assumptions

If your price depends on certain conditions, write them down. Examples:

This prevents disputes and protects you if the scope expands.

Step 5: Explain how to accept

Tell the client what to do next. "Reply to this email to approve" or "Sign and return this quote" creates a clear paper trail. Some businesses include a signature line at the bottom.

Step 6: Download and send

Export the quote as a PDF and send it by email. A PDF looks professional and prevents clients from editing the figures.
