The Proforma Structure

A proforma of invoice is a preliminary bill issued before goods are shipped or services are rendered, serving as a binding quote for the buyer. It differs from a final invoice because it does not request immediate payment but rather confirms the agreed price and terms.

When you need a proforma rather than a quotation, the context is usually formal trade or export. A quotation is an offer that can be withdrawn; a proforma is a firm commitment to those specific prices for a set period. If your client needs to arrange a bank letter of credit or import license, they will ask for the proforma. For standard domestic freelance work, a simple proposal or final invoice is usually sufficient.

Field-by-Field Layout

Use this structure to ensure your document is accepted by banks and accounting departments. Each field must be precise.

  • Proforma Invoice Number: A unique identifier, such as PI-2023-001, to track the document.
  • Date: The day the document is issued.
  • Seller Details: Your legal name, address, and GSTIN if you are registered in India.
  • Buyer Details: The client’s legal name, address, and contact person.
  • Item Description: Clear names of goods or services, including specifications.
  • Quantity and Unit Price: The amount of each item and the cost per unit.
  • Subtotal: The total value before taxes.
  • Taxes: GST or other applicable taxes. Note that if you are not GST registered, you must not collect GST or label this a GST tax invoice.
  • Grand Total: The final amount including all taxes.
  • Terms and Conditions: Payment currency, validity period (e.g., 30 days), and delivery terms.

When to Use It

Issuing a proforma is standard practice in international trade. Banks require it to issue letters of credit, ensuring the seller will be paid once goods are delivered. It also helps the buyer calculate landed costs, including duty and logistics, before committing to the purchase.

For domestic transactions, you might use a proforma when a client’s finance team requires a formal document to approve a budget before work begins. It acts as a bridge between the initial quote and the final tax invoice. If you are a freelancer providing ongoing services, you likely do not need a proforma for every task. However, if you are selling a one-off large package, such as a website build or a batch of manufactured goods, a proforma provides clarity and legal weight.

Generating the PDF

Once you have filled in the fields, you need a clean, professional PDF. You can create this manually in a word processor, but using a dedicated tool ensures formatting consistency and saves time. Invoiceful is a free online generator that runs directly in your browser. It requires no account and stores no data on a server. You can pick a template, fill in the details, and download the PDF immediately. It supports GST fields for Indian suppliers and can embed a UPI QR code, making it easy for clients to see exactly where to send payment if you choose to include it. The tool does not handle accounting or tax filing, so you remain responsible for recording the transaction in your own books once the work is complete.
