A quotation format is not a smaller invoice. An invoice records work already done; a quote is an offer that the other side can accept, and that difference decides what belongs on the page — a validity date, a clear scope, and an unambiguous way to say yes.
Most quotes that go unanswered are not too expensive. They are too vague to approve: the reader cannot tell exactly what they would be buying, or how long they have to decide.
The quotation format, line by line
- The word "Quotation" or "Quote", so nobody files it as an invoice, plus a unique quote number.
- Issue date and — the field most often missing — a valid-until date. Without it, a price from March can be waved at you in November.
- Your details: legal name, address, contact, and tax identifier where required.
- The client's legal entity name and address, spelled the way their finance team spells it.
- Line items: description, quantity or hours, unit price, line total. Specific enough that both sides could tick each line off on delivery.
- Subtotal, tax shown as its own line, any discount, and the total in the agreed currency.
- What is not included — the two lines that prevent most scope arguments.
- Lead time or delivery window, and what you need from the client to start.
- Payment terms: deposit, milestones, net days.
- How to accept: sign and return, reply in writing, or issue a purchase order. Say which one.
Give the client one number, not a range. A range communicates uncertainty and is read as the higher figure anyway. If the scope is genuinely unknown, quote a fixed price for a scoping phase and quote the rest afterwards.
Quote, estimate, proforma — which one you are sending
An estimate is an informed guess and can change. A quotation is a firm offer at a fixed price for a defined scope, and once accepted it forms a contract. A proforma invoice is a request for payment before delivery, often used for prepayment or customs, and is not a tax invoice.
Mixing them up is expensive in both directions: label a guess as a quotation and you may be held to it, label a firm offer as an estimate and the client will treat your price as negotiable.
The routine that gets quotes accepted
- Confirm the scope in writing before you price it, and quote against those words rather than your own summary.
- Send it the same day the conversation happened. Speed reads as competence, and most work is awarded to whoever replies first with something concrete.
- Send a PDF, not an editable document — a quote that can be altered is a quote that will be.
- Name the acceptance method and the valid-until date in the covering message, not only in the document.
- Follow up two days before the quote expires. That deadline is the reason the follow-up is welcome rather than pushy.
- When it is accepted, convert the quote to an invoice with the same numbers and reference the quote number on it.
Ettex Invoices handles the document side of that loop: line items with quantities, rates, multiple tax rates and discounts, notes and terms fields where validity, exclusions and acceptance instructions belong, sequential auto-numbering with your own prefix, your logo and colours on every document, a client book so entity names and addresses stay identical between the quote and the invoice that follows, statuses from draft to sent to paid, duplication so a quote becomes the invoice without retyping, and export as print-ready PDF or as CSV and XLS for the books. When a quote needs a signature to count as accepted, Ettex Sign turns it into a signature request with reminders and an audit trail.
Mistakes that cost the job
- No expiry date, which leaves your pricing exposed indefinitely.
- A single line reading "design work — 4,000". Specific lines are what make a price feel reasonable.
- Tax treatment left implicit, then argued about at invoice time.
- Sending a quote that does not say how to accept it, so the client has to invent the next step.
- Different numbering between the quote and the invoice, so nobody can match the two later.
Frequently asked
What is the difference between a quotation and an invoice?
A quotation offers to do work at a stated price before it happens. An invoice requests payment for work already delivered. The invoice should reference the quote it came from.
How long should a quotation be valid?
Fourteen to thirty days suits most work. Shorter where your costs move; longer only if you can absorb the risk of price changes.
Is a quotation legally binding?
Once accepted by the client on its stated terms, a quotation generally forms a contract. That is why the scope, exclusions and validity date matter so much.
Should a quote include tax?
Show the tax as its own line and the total including it, unless you are quoting business-to-business in a market where net pricing is the norm — in which case say so explicitly.
Can I change a quote after sending it?
You can issue a revised quote with a new number and mark the previous one superseded. Editing the original silently is how two versions end up in circulation.
A quotation format that converts is boringly complete: one price, a defined scope, an expiry date and a way to say yes. The rest is presentation.
