Proforma invoice vs quotation sent in the right order
A quotation is your offer before the buyer commits. A proforma follows the yes, laid out like the final bill, so they can pay ahead, arrange imports or get approval.

A quotation is a price offer sent before the buyer commits, and they can accept, negotiate or ignore it. A proforma invoice is sent once the buyer agrees, set out like the final invoice so they can pay in advance, prepare import paperwork or approve spending. Neither is the final invoice, which you issue when the goods ship or the work is done.
What each document is
A quotation is a written offer to supply goods or services at stated prices, for a stated period. A proforma invoice is a preliminary bill that shows exactly what the final invoice will contain once the sale goes ahead. One invites a decision; the other confirms the details of a decision already made, or about to be.
- Quotation: prepared on request, often one of several the buyer compares. Carries a valid until date. Once accepted, it usually forms the contract.
- Proforma invoice: prepared after the buyer confirms the order, or when they need a formal document to release funds. Shows quantities, prices, delivery terms and payment terms, but is not recorded as a sale.
- Commercial or final invoice: the actual bill, issued when goods ship or work is done, and the document your accounts record.
Some exporters send a proforma in place of a quotation from the start, because the buyer’s bank or importer wants that format. The document is the same; only the timing changes.
Quotation vs proforma invoice, side by side
The two documents can look almost identical, with the same line items, prices and totals. The differences lie in purpose, timing and how each is treated afterwards. Use the table to check which one a buyer is really asking for, and remember that tax rules on invoices vary by country.
| Detail | Quotation | Proforma invoice |
|---|---|---|
| Purpose | Offer a price and win the order | Confirm the order details before billing |
| Stage | Before the buyer commits | After agreement, before supply |
| Price status | Open to negotiation | Agreed, unless the order changes |
| Payment | None requested | Often used to request an advance |
| In your books | Not recorded | Usually not recorded as a sale |
| Tax claims | Cannot be used | Usually cannot be used; the final invoice is the tax document |
| Used by banks or customs | Rarely | Often, to support payments or import paperwork |
| Key date | Valid until | Valid until, plus expected shipping date |
| Number series | QT-2026-118 | PF-2026-041, separate from invoices |

Where each one sits in the sale
In a typical order the quotation comes early and the proforma comes late, just before money or goods move. Not every sale uses every step. A local service job often goes straight from quotation to invoice, while an export order for manufactured goods may use all of them, in the sequence below.
- RequestThe buyer sends an inquiry or a formal request for quotation.
- QuotationYou reply with prices, delivery terms and a valid until date.
- Acceptance or purchase orderThe buyer accepts the quotation or sends a purchase order referring to it.
- Proforma invoiceYou confirm the final quantities, prices, freight and payment terms on a proforma.
- Advance paymentThe buyer pays the agreed advance, or their bank acts on the proforma.
- SupplyYou make or ship the goods, or carry out the work.
- Final invoiceYou issue the commercial or tax invoice, deducting the advance.
Worked example: an export order
A small manufacturer quotes an overseas distributor for 200 stainless steel shelf brackets. The distributor accepts and asks for a proforma so their bank can release a 30% advance. The figures stay the same from quotation to proforma; what changes is the purpose of each document and what the buyer does with it.
| Item | Working | Amount |
|---|---|---|
| Brackets | 200 each × $18.50 | $3,700.00 |
| Freight to port of destination | Flat rate on the quotation | $240.00 |
| Order total | $3,700 + $240 | $3,940.00 |
| Advance on proforma PF-2026-041 | 30% × $3,940 | $1,182.00 |
| Balance on final invoice | $3,940 − $1,182 | $2,758.00 |
Quotation QT-2026-118 carried a valid until date and the delivery terms. Proforma PF-2026-041 repeated them, added the bank details and the advance, and noted the expected ship date. The final invoice, issued at shipment, showed the full $3,940, the $1,182 already received and $2,758 due.
When a buyer will ask for a proforma
Buyers ask for a proforma when they need a formal document that looks like an invoice before the real invoice can exist. The most common reasons are paying an advance before production, supporting import paperwork, satisfying a bank, or getting an internal purchase approved by someone who will not sign off on a quotation.
- Advance payment for goods made to order, or for large material purchases on a project.
- Import preparation, where the buyer needs values, weights and descriptions in advance.
- Bank requirements, such as supporting a transfer or other trade payment arrangement.
- Internal approval, where an accounts team needs an invoice-style document to raise a payment.
- Confirming final details after changes to quantities or freight during negotiation.
When a quotation is the right document
For most trade and service work a quotation, followed by an invoice, is all you need. The customer compares prices, accepts one, and you bill a deposit or the full amount as agreed. A proforma only adds value when someone in the chain needs an invoice-shaped document before the sale is final.
Use a quotation when the buyer is still comparing suppliers, when the scope may change, or when the work is local and payment follows a normal deposit and balance. A formal layout with a reference number and terms suits buyers in the UK, India and the UAE, and our formal quotation maker builds one. The quotation format guide labels each part.

Mistakes that confuse buyers and bookkeepers
The trouble with two look-alike documents is that people treat one as the other. Most mistakes come from recording a proforma as a sale, numbering it in the invoice series, or letting its figures drift from the accepted quotation. Each one creates a mismatch that someone has to untangle later, often at tax time.
- Recording a proforma in your sales or receivables, then recording the final invoice as well.
- Numbering proformas in the invoice sequence, which leaves gaps when an order falls through.
- Prices on the proforma that differ from the accepted quotation with no explanation.
- Leaving off a valid until date, so an old proforma is presented months later.
- Labeling a proforma as a tax invoice. Tax rules decide what counts as one, and they differ by country.
- Forgetting to deduct the advance on the final invoice.
Making each document
Use separate templates and separate number series for quotations, proformas and invoices, so each document is obviously what it says it is. Build the quotation first; the proforma and the invoice are then copies with their headings, numbers, dates and payment details changed, never retyped from scratch.

Questions about proformas and quotations
Is a proforma invoice a quotation?
Not quite. Both show prices before supply, but a quotation is an offer the buyer may refuse, while a proforma usually confirms details the buyer has already agreed. Some exporters do send a proforma as their first price document, so read what the buyer is asking for.
Is a proforma invoice legally binding?
A proforma is not normally a demand for payment in the way a final invoice is. Whether it forms part of a binding agreement depends on what was agreed around it, such as an accepted quotation or a purchase order. See is a quote legally binding for the general principles.
Can a buyer pay against a quotation?
They can, but it is cleaner to accept the quotation first and then pay against a deposit invoice or a proforma. That way the payment is matched to a numbered document with clear payment terms, and your records show what the money was for.
Does a proforma show tax?
It usually shows the tax that will apply, so the buyer sees the full amount. It is not normally the document used to claim tax back; the final invoice is. What a tax invoice must contain depends on your country, so check the relevant country page.
Who issues a proforma, the buyer or the seller?
The seller. The buyer requests it, often for a bank, an import process or an internal approval, and the seller prepares it from the agreed quotation or purchase order, numbered in a proforma series kept apart from invoices.
