What Should a Professional Quotation Include?
A professional quotation should tell the customer exactly what is included, what it costs, how long the price is valid and what happens after approval. It should be detailed enough to prevent misunderstanding, but not so complicated that the customer avoids responding.

Example quotation terms
Quotation valid for 15 days from issue date.
50% advance required to begin work.
Balance payable before final delivery.
Prices exclude extra work outside the agreed scope.
GST, if applicable, will be charged as shown in the quotation.
After the customer approves a quotation, create the invoice using the same line items and terms unless something changed. This keeps the sales and billing record easy to follow.
Example quotation structure
For a website maintenance quotation, write the scope as monthly updates, security checks and small content changes up to a defined limit. Show the monthly price, GST if applicable, payment due date, start date and validity. If work outside scope is billed separately, say that clearly. This prevents the quotation from becoming an unlimited promise.
Approval language
Please reply Approved to confirm this quotation.
Work will begin after advance payment is received.
Any change in scope may require a revised quotation.
This quotation is valid until the date mentioned above.
A quotation becomes more useful when approval is easy. If the customer must call to understand the next step, the document is incomplete. Add WhatsApp or email instructions so the customer knows how to proceed.
How to avoid quotation disputes
Most disputes happen because the customer assumed something was included. Write the scope plainly. If delivery, installation, revision rounds, travel charges or urgent work costs extra, mention that in the quotation. A shorter quotation with precise terms is usually better than a long document that hides important conditions.
When the quotation is approved, keep a copy and use it as the base for the invoice. This makes the final bill easier to explain and reduces back-and-forth at payment time.
Should a quotation include GST?
Include GST where it applies and show it clearly. If you are unsure about tax treatment, verify before sending.
How long should a quotation be valid?
Many businesses use 7, 15 or 30 days depending on price volatility and project type. Choose a validity period you can honour.
