Example of Sales Invoice Format and Template

Using a sales invoice template simplifies your invoicing processing by saving time and ensuring accuracy. With pre-set fields, you only need to input details like customer information and item descriptions. These templates also ensure consistency in your invoices, reducing the risk of errors and making it easier for you and your customers to track payments.

Types of Sales Invoices

1. Standard Invoice

A standard invoice is the most widely used type for requesting payment. Small businesses commonly use this for everyday transactions, whether selling products or offering services. It outlines the goods or services provided and the total amount due.

2. Credit Invoice

A credit invoice is issued when a refund or discount is applied. It reflects a negative total, reducing the amount the customer owes. This type is typically used for returns, cancellations, or overpayments.

3. Debit Invoice

A debit invoice increases the amount owed by the customer. It’s issued when additional services or charges apply, such as when a project takes longer than expected or when there are unforeseen costs.

4. Commercial Invoice

A commercial invoice is used for international sales. It details cross-border transactions and is essential for customs purposes, providing information on the goods, the buyer and seller, and applicable duties and taxes.

5. Proforma Invoice

A proforma invoice is a preliminary bill sent to a customer before the delivery of goods or services. It provides an estimated cost breakdown, allowing the customer to understand potential expenses. However, the final invoice may differ slightly once the actual goods are delivered or services are completed.

6. Interim Invoice

An interim invoice is used for large projects where payments are made in increments. These invoices are issued periodically throughout the project and are followed by a final invoice once the project is complete.

7. Past-due Invoice

A past-due invoice is sent when a customer hasn’t made a payment by the due date. This invoice may include penalty fees or interest charges to encourage prompt payment.

How to Create a Sales Invoice? A Step-by-Step Guide

STEP 1: Add Your Business Information

Start by adding your company logo, business name, address, phone number, and email. Ensure all contact information is accurate and professional, as this makes it easier for clients to reach you with any questions.

STEP 2: Add Your Client’s Contact Details

List the customer’s full name, address, and contact information below your business details. If you’re invoicing a larger company, confirm the correct contact person to avoid delays in payment processing.

STEP 3: Generate an Invoice Number

Assign a unique invoice number for easy tracking and reference. You can either create a systematic numbering approach (e.g., INV001, INV002) or use accounting software to automate this process.

STEP 4: List Services or Products Provided

Itemise the products or services you’ve provided. Include brief descriptions, quantities, or hours worked, along with unit rates. This level of detail ensures clarity for the client and reduces the likelihood of disputes.

STEP 5: Specify Payment Terms

Outline the accepted payment methods, such as cash, cheque, or credit card. If you charge interest on late payments, mention the terms clearly to avoid misunderstandings later.

STEP 6: Specify a Payment Due Date

Clearly list the payment deadline. Typically, the due date is calculated based on the invoice date and your specified payment terms (e.g., 30 days from the date of issue).

STEP 7: Calculate and Display the Total Amount Due

Provide the final balance due, including applicable taxes (such as GST). If there are any credits, deposits, or discounts, subtract these from the total amount to give the final payable figure.
