What is a proforma invoice template?
A proforma invoice is a preliminary bill sent to a buyer before a sale is finalized, setting out the goods or services, the price and the terms. It is essentially a detailed, good-faith quote in invoice form, not a demand for payment or a record of a completed sale.
Businesses use a proforma invoice to confirm an order, request a deposit, support a customs or import estimate, or let a buyer arrange financing before the final invoice. It is common in international trade and for large or custom orders.
What to include in a proforma invoice
A proforma invoice mirrors the final invoice but is clearly marked as preliminary:
- The words "Proforma Invoice": Label it clearly so it is not mistaken for a final invoice or a payment demand
- Your business details: Your legal or trading name, address, email, phone and logo, so the client knows exactly who to pay
- The word "Invoice" and a unique invoice number: A clear label and a sequential number (for example INV-0001) that you can reference in your records and the client can quote when paying
- Client details: The customer's name or company, billing address and contact, so the invoice reaches the right person
- Invoice date and due date: The date issued and the date payment is due, plus your terms such as Net 15 or Net 30
- Itemized list of goods or services: A line for each item with a description, quantity, rate and line total, so the charges are easy to follow
- Validity period: How long the quoted prices and terms are valid, since a proforma is an offer, not a settled sale
- Estimated totals and terms: The estimated subtotal, tax or duties where known, total, and the proposed payment and delivery terms

When a proforma invoice template is not enough
A proforma invoice template is a fine way to send a clean, professional bill. What it cannot do is keep track of what you have invoiced, chase the payments that are late, and tie every paid invoice back to your books. That work grows quietly as your business does.
FinStackk is an accounting and tax compliance platform for U.S. businesses, and its bookkeeping module, Fin-Books, takes that work off your plate. The Fin-Books team manages customer invoicing, invoice follow-ups, accounts receivable and reconciliation as part of your monthly books, so revenue is recorded correctly and nothing falls through the cracks.
That matters most when invoices turn into tax and compliance obligations: recognizing revenue in the right period, reconciling deposits, tracking sales tax you collect, and keeping GAAP-ready financials for a lender or investor. If you have outgrown filling in a template by hand, that is the point to move from a blank file to managed books.
Common mistakes to avoid on a proforma invoice
- Treating it as a final invoice: A proforma is not booked as revenue or used for tax; issue a final sales or commercial invoice once the sale completes
- No validity date: Prices and terms change; state how long the quote holds so there is no dispute later
- Leaving off delivery terms: For trade, include Incoterms and estimated shipping so the buyer sees the full landed picture
- Forgetting to follow up with the real invoice: When the order is confirmed and shipped or delivered, issue the actual invoice; the proforma does not replace it
Frequently asked questions (FAQ)
What is a proforma invoice?
A proforma invoice is a preliminary invoice or detailed quote sent before a sale is final. It states the goods, price and terms so the buyer can confirm the order, pay a deposit, or arrange import and financing.
Is a proforma invoice a legal invoice?
No. It is not a demand for payment and is not recorded as a sale or used for tax. It is an offer; the final sales or commercial invoice is the legal document once the sale completes.
When should I use a proforma invoice?
Use it to confirm an order before delivery, request a deposit, or provide a customs or financing estimate, especially in international trade and for large custom orders.
Is this proforma invoice template free?
Yes. Download it in Word, Excel or PDF and use it for unlimited quotes at no cost.
Can I use AI or ChatGPT to create an invoice?
You can ask an AI tool to draft invoice wording, but it will not reliably calculate your totals or tax, and it keeps no record of what you have billed. A ready-made template, or the generator above, is faster and more accurate for the invoice itself. For the accounting behind your invoices, recording the revenue, reconciling the payment and tracking what clients owe, FinStackk's Fin-Books handles that as part of your US bookkeeping.
Which format should I use: Word, Excel, PDF, or Google Docs and Sheets?
Use Word or Google Docs when you want to type into a document and control the layout. Use Excel or Google Sheets when you want the line totals, subtotal and tax calculated for you. Use the PDF when you just need a fixed file to print or send. Many businesses keep an editable master in one format and send a PDF to the client.
How do I get paid faster, and what should I do about late payments?
Send the invoice the day the work is done, set short and clear terms such as Net 15, make payment easy, and follow up politely the day after the due date. As your invoice volume grows, chasing payments by hand gets expensive. FinStackk's Fin-Books manages customer invoicing, invoice follow-ups and accounts receivable, so late invoices get chased and your books stay current.
Do I need to charge sales tax on an invoice?
It depends on what you sell and where the customer is. Many professional services are not taxed, but most states tax physical goods and some tax specific services. If you have sales tax nexus in a state and sell something taxable there, you generally collect and remit the tax. FinStackk's Fin-Tax helps US businesses identify and manage their sales tax obligations as they grow.
Is a proforma invoice legally binding or counted as a sale?
No. A proforma invoice is a preliminary quote sent before the sale is final. It is not a demand for payment, is not recorded as revenue, and is not used for tax. Once the order is confirmed and delivered, you issue a final sales or commercial invoice, which is the document that counts for your books.
