Quotation Letter Format for Suppliers
A quotation letter states what you will charge for a defined supply — price, taxes, validity and terms. It is the pre-contract document that sets buyer expectations and protects both sides before a purchase order is issued.
This guide covers the quotation letter format, the fields buyers check, validity and GST treatment, and how to generate a professional quotation with the free Crafex quotation generator.
A clear quotation is also your sales tool — buyers compare quotes on exactly these fields.
What a quotation letter must show
Quote number and date, buyer details, itemised description with quantity, unit price, GST lines or note, validity period, payment terms and delivery. Every field a buyer uses to compare quotes should be explicit.
| Field | Why it matters |
|---|---|
| Quote number/date | Tracking and reference link to the PO |
| Itemised scope | Exact goods/services to avoid scope creep |
| Unit price + total | The arithmetic buyers compare |
| GST line | Intra/inter-state tax split clarity |
| Validity | How long the price holds |
| Payment & delivery | Terms that close the deal |
Validity and pricing locks
State validity explicitly — 'this price is valid for 30 days' — so cost changes after acceptance don't become disputes. Options (add-ons) carry their own prices and validity.
GST on quotations
Quotations are not tax documents, but buyers compare total cost inclusive of GST. Show the tax split when you know the recipient's state to keep your quote the easiest to sign.
From quotation to purchase order
The buyer's acceptance — a signed purchase order or confirmation — converts your quotation into a contract. Reference your quote number on the PO so both documents reconcile.

The Crafex quotation generator produces a professional quotation letter — itemised, tax-lined, with validity and terms — as a downloadable PDF in seconds.
Formal letter anatomy: from date line to enclosure
The anatomy of a professional business letter is fixed: the sender's head, the date, the recipient block, the subject line, the salutation, the body, the close and the signature. Each zone earns the reader time by telling them where they are in the letter.
The date and subject line deserve the strictest formatting — a letter that banks or offices will file must sort cleanly by its date and survive retrieval by its subject. Keep the salutation with the recipient's full name and the recognized title.
End with the enclosure list when attachments travel with the letter; the list protects both the sender from the 'never received' reply and the archive from a stray file.
Complaint letters that get action
An effective complaint business letter states the issue in the subject line, the evidence in the second paragraph and the desired resolution in the final. Time is on the side of the letter that lets someone act without a second message.
Attach the evidence — order number, receipt, dated screenshots — and reference each attachment in the body so the file is complete before the reply. Give the addressee a reasonable date for a response so the follow-up has a hook to hang on.
Keep the tone firm without accusation; a letter that insults the reader is a letter that gets buried, while a letter that requests within the terms of the contract gets routed to the person empowered to help.
The professional close of a business letter
The close carries the ask, the contact line and the courtesy: state the call to action plainly, then the phone and email, then the formal valediction. The final paragraph is the one that survives in the reader's memory.
Match the close to the salutation's register for tone; a formal letter's 'Yours faithfully' answers to 'Dear Sir', while 'Yours sincerely' belongs to the named reader. The pair communicates how the letter thinks of its recipient.
Write the close before the body in drafting when the letter is long; the habit forces the call to action to exist, and the body to argue for it.
Anatomy of a professional business letter
Every professional business letter follows the same skeleton: sender's letterhead, date, recipient address, subject line, salutation, body, closing line, signature block and enclosures.
The subject line does the heavy lifting in email era — make it specific enough that the reader knows the outcome you need before opening the letter.
Email vs printed business letters
Most business correspondence now moves by email, but formal documents — legal notices, loan applications, vendor agreements — still demand a printed letter on letterhead.
Keep a PDF of every business letter you send; scanned signed copies are accepted as legal evidence in Indian courts.
Tone and language
Professional business letters use clear, courteous, action-oriented language. Short paragraphs, active voice and a single ask per letter outperform dense, legalistic prose.
Address the recipient formally until invited otherwise, and always close with the expected action and a deadline.
Formatting emails as business letters
Most routine business letters now travel as emails, but they should still follow letter discipline: a clear subject line in place of the title, a courteous opening, a single ask, and a signature block with your designation and contact.
Email etiquette that mirrors letter etiquette — short paragraphs, formal address until invited otherwise, and a stated deadline — keeps digital correspondence on equal footing with printed letters.
Drafting business letters quickly from a bank
Professionals keep a small bank of business letter masters — payment request, introduction, quotation, leave, complaint — and adapt them per case. The masters carry the skeleton; the adaptation replaces names, dates and specifics.
A master bank speeds drafting by 80% and keeps quality consistent. Review each master twice a year against changing formats and your letterhead.
When to send printed business letters
Legal notices, formal complaints to government bodies and documents with signatures still command printed business letters on letterhead. Courts admit printed letters with signatures far more readily than unsigned emails.
Keep a PDF scan of every printed business letter you send — the scan preserves the signature block and gives you the record without retaining the paper.
The three-ask rule for business letter clarity
A business letter carries exactly one primary ask. When you need several things, number them and rank them — 'please confirm receipt by Friday, approve the amount by Monday, and we will schedule delivery next week.'
Readers act on a single clear request; they defer ambiguous ones. If a business letter needs more than three numbered actions, it needs a separate letter.
Reviewing business letters before sending
The ten-second review catches the errors that erode professionalism: a wrong name, a date slip, or a missing attachment. Read the business letter aloud once before sending — mis-addressed names, awkward phrasing and missing enclosures surface immediately.
For high-stakes business letters — notice, disputes, agreements — add a second reviewer pass. The extra minute is what separates a polished record from a costly typo.
The language of professional business letters
Professional business letters speak in short sentences and active verbs: 'we request payment by 15 August' beats 'it is requested that the payment may kindly be made'. Indian professional writing favours courtesy with clarity — courteous opening, direct ask, polite close.
Read your draft aloud and cut every phrase that does not carry information. Formality is a default, not a requirement, for every sentence. Delete the archaisms — 'kindly find', 'hereby', 'duly' — and say the same thing in half the words.
Keep the tone warm but not casual; a letter that reads like a message app exchange raises the risk of the matter being taken lightly on the other side.
Handling objections with a business letter
A well-drafted business letter anticipates the reader's objection and answers it: the payment letter states the invoice reference and due date; the complaint letter includes the proof; the introduction letter includes the client proof. Answer the objection and the letter works.
List the three questions the reader will ask, and answer each one before closing. Put the answer to the biggest objection in the second paragraph, not the last — readers most often stop after the opening.
Where a call is the real vehicle, use the letter to set the agenda in writing so the call starts from a shared document rather than from memory.
The signature block that completes a business letter
The signature block closes the professional record: your full name, designation, company, phone, email and, where relevant, the GSTIN. Banks and offices file letters by the signature block.
Keep the block identical across your business letters — inconsistency in contact details is a quiet professionalism killer. Match the signatory's name with the salutation: a letter to 'Dear Ms Sharma' should never close with a different name at the desk.
Add a line with the office address for registered communication if the letter concerns a dispute or a statutory matter; the two addresses make the record complete for legal use.
Frequently asked questions
What must a quotation letter include?+
Quote number, buyer details, itemised scope with prices, GST line, validity, payment terms, delivery and your contact. Everything a buyer needs to compare and decide.
Is a quotation legally binding?+
No — it is an offer. It becomes binding when the buyer accepts (typically by purchase order or signed acceptance) within the validity period.
How long should a quotation stay valid?+
Common practice is 15–30 days. Shorter validity protects you from price swings; longer helps slow procurement cycles.
Should I show GST on a quotation?+
Yes, when the tax treatment is known — buyers compare total cost. Show CGST+SGST or IGST as applicable.
