Understanding Proforma Invoice: Uses and Examples

You have just closed a promising deal with a new customer. They are ready to proceed, but there is a catch—they need clear, written confirmation of costs, terms, and delivery details before they can finalize the purchase. How do you ensure transparency without committing to a formal invoice too soon? This is where a proforma invoice becomes invaluable.

Think of a vendor exporting a shipment to Singapore. The buyer requests detailed cost breakdowns, item specifications, and payment terms before arranging customs clearance. A proforma invoice bridges this gap by providing a pre-sale document that ensures both parties are on the same page. It sets expectations, eliminates misunderstandings, and builds trust—especially in international trade.

If you have ever struggled with unclear terms or lost deals due to miscommunication, this guide is for you. We will walk you through the purpose, uses, and practical examples of proforma invoices, ensuring you understand how they align buyer and seller expectations seamlessly. By the end, you will know exactly when and how to use this document to simplify your sales process. 

What is a Proforma Invoice?

A proforma invoice is a document shared with a customer before a sale is final. It shows the details of the deal, like product descriptions, prices, quantities, shipping costs, and delivery dates. However, it is not a bill or a payment request.

This type of invoice helps vendors and customers understand all terms clearly before proceeding. It is especially useful for international trade, as customs officials often need a proforma invoice to determine duties or taxes.

Think of it as a detailed quote. It sets clear expectations for both sides and reduces the chance of misunderstandings. For vendors, it is a simple way to build trust and ensure everyone agrees on the details before the actual sale happens.

Difference Between Proforma and Other Invoices

Understanding how a proforma invoice is different from other invoices is important. It helps avoid confusion and ensures smooth transactions. Let us break it down:

1. Proforma Invoice vs. Sales Invoice

A proforma invoice is sent before delivering goods or services. It shows the price, product details, and terms of sale. But it is not a legal document. It does not ask for payment, and it is only meant to confirm the agreement between the vendor and the customer.

A sales invoice, however, is sent after delivery. It is a legal document that requires the customer to make a payment. 

2. Proforma Invoice vs. Commercial Invoice

A commercial invoice is essential in international trade. It is issued after a sale is final and is needed for customs clearance. This document lists the total value of the shipment, along with taxes and duties. Customs officials use it to calculate fees.

A proforma invoice is shared earlier before the deal is final. It outlines terms and confirms agreement with the buyer. While both invoices may look similar, only the commercial invoice is legally valid for customs.

3. Proforma Invoice vs. Quote

A quote gives a buyer a rough cost estimate at the start of the process. It is usually simple and does not include detailed terms or shipping information.

A proforma invoice is more detailed and comes later. It includes final prices, quantities, and shipping details after the buyer shows interest in moving forward.

Benefits of Using a Proforma Invoice in Business Transactions

A proforma invoice is a simple yet powerful tool that helps businesses stay organized and avoid problems. Here are three key ways it is used:

1. Helps With Negotiations and Setting Clear Expectations

When buyers and vendors talk about deals, both need to understand the terms clearly. A proforma invoice lists all the important details, like product prices, quantities, shipping costs, and delivery timelines. This makes it easier for both sides to agree on the terms. 

For example, if a buyer wants to negotiate discounts or request changes, the proforma invoice gives them a clear starting point. It ensures there are no surprises later, saving time and building trust.

2. Important for International Trade and Customs Clearance

In international trade, customs officials need detailed information about shipments. A proforma invoice provides this information, including the value, type, and origin of the goods. This helps customs calculate duties or taxes and speeds up the clearance process. For vendors exporting goods to places like Singapore, a proforma invoice ensures the shipment complies with regulations. It helps avoid delays and keeps the goods moving on schedule.

3. Useful for Internal Approvals and Cash Flow Planning

Some businesses need approval before buying goods. A proforma invoice makes this process easier by clearly showing costs and terms. Decision-makers can use this document to approve purchases quickly. It also helps with managing cash flow. Vendors can plan their revenue based on future sales, while buyers can prepare their budgets. This way, both sides stay financially prepared without last-minute surprises.

When to Issue a Proforma Invoice?

A proforma invoice is issued at specific points in the sales process to simplify communication and avoid misunderstandings. Here are the key situations where this document is most useful:

1. Before Finalizing the Sale or Delivering Goods

A proforma invoice is sent when both sides are still discussing the details of a sale. It lays out the full picture—prices, quantities, shipping costs, and terms—before any commitments are made. For vendors, this is a great way to show transparency, and for customers, it helps them feel confident in their decision. 

For example, if a buyer needs to see the total costs, including taxes and delivery fees, a proforma invoice gives them a clear estimate to review.

2. During Early Sales Talks or For Global Trade Deals

When you’re still in the “talking phase” of a sale, a proforma invoice is a practical tool. Vendors use it to give potential customers a precise cost estimate, making it easier to move forward. 

For international transactions, it’s even more critical. Customs officials use the proforma invoice to calculate duties and taxes on imports. Without it, shipments can get delayed or stuck. Vendors shipping goods overseas, especially to places like Singapore, rely on this document to keep trade flowing smoothly.

3. Before Production in Manufacturing

In manufacturing, mistakes can be costly. A proforma invoice ensures both the vendor and the customer agree on every detail before production starts. It spells out product specifications, prices, and any custom requirements, avoiding any confusion down the line. 

For instance, if a manufacturer is producing custom parts, the proforma invoice lets the buyer double-check all the details before production begins. This step avoids errors, saves time, and keeps everything on schedule.

Creating a Proforma Invoice

A proforma invoice needs to be clear, accurate, and easy to understand. Here’s how to create one step by step:

1. Add Seller and Buyer Details, Product Descriptions, and Estimated Costs

Begin by listing your business name, address, and contact information. Include the buyer’s name, address, and contact details. After that, describe the products or services you are offering. Be specific about the item names, quantities, and provisional costs. For instance, instead of “electronics,” write “Model X Laptop, 16GB RAM, 512GB SSD.” This helps avoid confusion and ensures your customer knows exactly what they are getting.

2. Clearly Label the Document as a ‘Proforma Invoice.’

At the top of the page, write “Proforma Invoice” in bold. This prevents it from being mistaken for a standard invoice or a payment request. You can also include a reference number and date for better tracking. Proper labeling keeps things organized and avoids unnecessary back-and-forth between you and your customer.

3. Include Payment Terms, Delivery Details, and Any Terms and Conditions

Clearly explain how and when the payment should be made. Mention accepted payment methods, like bank transfers or credit cards. Add details about the expected shipment date, delivery method, and any extra shipping charges. Also, include terms such as return policies, warranty details, or any specific conditions related to the deal. This makes everything clear for your customer and ensures both sides agree on the terms.

Example Proforma Invoice Template

Although the structure may vary depending on your industry or company’s guidelines, here is an example of a proforma invoice that will help you understand and create one.

A well-made proforma invoice keeps things simple and clear. It ensures your customer knows what to expect and avoids delays caused by confusion. This document not only looks professional but also helps build trust, moving the deal forward smoothly.

Examples of Proforma Invoice Usage

A proforma invoice plays an important role in different industries and scenarios. Here are two key examples that highlight its practical uses:

1. In manufacturing: Provided Before Production Starts to Outline Costs

Manufacturers rely on precise agreements before starting production. A proforma invoice helps confirm an order’s details, such as product specifications, quantities, and costs. It ensures both the vendor and the customer agree on what is being produced and the associated charges.

Example Scenario:

Suppose a furniture manufacturer in Singapore receives an order for custom office desks. The buyer needs ten desks with specific dimensions, wood types, and finishes. Before starting production, the manufacturer sends a proforma invoice detailing the materials, unit costs, total costs, and expected delivery date.

The invoice looks like this:

• Item Description: Custom office desk, 120cm x 60cm, teak wood with walnut finish
• Quantity: 10
• Unit Price: SGD 800
• Total Cost: SGD 8,000

This gives the buyer time to review and approve the order. It also provides a reference point for both parties, reducing the risk of disputes during or after production.

2. In International Trade: Used for Customs and Pre-payment Agreements

When goods are shipped internationally, customs authorities often require a proforma invoice to process the shipment. The invoice provides details like product value, origin, and shipping costs, helping calculate duties and taxes. Vendors also use it to set terms for pre-payment agreements with international buyers.

Example Scenario:

A Singapore-based electronics supplier is exporting 50 units of a wireless speaker to a retailer in Europe. The retailer needs a proforma invoice to calculate the total import costs, including shipping and customs duties. 

The supplier sends an invoice with the following details:

• Item Description: Wireless Bluetooth speaker, Model B100
• Quantity: 50
• Unit Price: SGD 100
• Shipping Cost: SGD 500
• Provisional Total: SGD 5,500

The proforma invoice helps the retailer prepare payment for the goods and customs fees. At the same time, customs uses it to verify the shipment’s value and ensure compliance with trade regulations.

Best Practices for Using Proforma Invoices

A proforma invoice works best when it’s clear, accurate, and easy to manage. To make the most of this document, vendors should focus on clarity, efficiency, and keeping details up-to-date. Here’s how you can do it:

1. Be Clear and Transparent to Build Trust

A proforma invoice should always explain the details of the deal clearly. Include specific product descriptions, quantities, costs, and terms of the sale. Avoid vague language that might confuse the buyer.

For example, instead of writing “custom parts,” describe them as “Precision-cut steel parts, 10mm thickness, polished finish.” This level of detail shows professionalism. When buyers see exactly what they’re paying for, they feel confident about moving forward. Clear invoices also help avoid misunderstandings, making it easier to build trust and long-term relationships.

2. Use Invoicing Software to Save Time and Avoid Errors

Creating and managing proforma invoices manually takes time and can lead to mistakes. Using invoicing software simplifies this process. With these tools, you can create professional invoices, update them as needed, and send them to buyers quickly.

Many tools also let you track when an invoice is viewed. This feature helps you follow up at the right time. By automating the process, you avoid typing errors and make sure your customer gets accurate information.

Example Tip: Use e-invoice software that connects to your accounting or inventory systems. This integration automatically updates prices and stock details and ensures every invoice reflects the latest data, reducing confusion or delays.

3. Keep the Details Updated For Accuracy

Negotiations or changing conditions can affect the information on a proforma invoice. Always update the document if shipping costs, product quantities, or payment terms change. This way, the customer always knows the latest terms.

For example, if shipping fees increase after the first draft of the invoice, update it immediately and send the revised version. If the invoice isn’t updated, the buyer might question the final invoice, leading to delays or disputes. Regularly reviewing and updating the invoice ensures everything stays accurate and smooth.
