A sales invoice or commercial invoice is a document that requests payment for goods or services provided to a customer. It is an essential part of the invoicing process, as it outlines the payment terms and helps ensure you get paid for your work.

This article will provide an overview of a sales invoice and its importance, how to create one, and a bonus tip on requesting a payment. 

We will also discuss the key elements that should be included in a sales invoice and provide the best practices for creating and sending sales invoices.

What is a Sales Invoice?

Sales Invoice Calculation

A sales invoice is a document that asks for payment for goods or services provided to a customer.

Due to the uncertainty of what information to include, writing an invoice is challenging if it’s the first time you are doing it.

A sales invoice typically includes information about what was provided, the cost, and the payment terms. It is issued after the goods or services have been delivered.

But in some cases, the invoice is issued even before. This happens when a sales agreement specifies the payment to be made in advance. 

Sales invoices are used in many industries and are an important part of invoicing since they help process business transactions.

Sales invoices help set clear payment terms and ensure businesses receive payment for their work.

Why are Sales Invoices important?

Sales invoices are a vital part of running a successful business to account for expenses and end up with a profit.

It is also important to keep track of the invoices issued and the payment status of each invoice. This way, a business can better understand its overall sales performance and cash flow. This can help them to make more informed business decisions and plan for the future.

Despite the benefits that sales invoices provide to a business in terms of future planning, it also helps manage accounting documents.

Accounting Workflow

Invoices are a crucial part of maintaining organized and accurate financial records. They provide a clear record of each sale and transaction, which can be used to update an accounting document, such as a financial statement that tracks income and expenses.

Invoices are also important when it comes to tax time. When you file your taxes, you must report your income and expenses. Having a clear record of your invoices lets you quickly reference the income and expenses you need to report on your tax return.

Inventory Management

In case when a business sells physical products, issuing sales invoices is equally important in managing inventory.

Every time you sell something, you will know how much inventory is still available, giving you an overview of accurate data.

Such information also helps your marketing by determining the best time to promote a product based on its selling behavior.

How to Create a Professional Sales Invoice

By following a few simple steps, you can create a professional invoice that meets the needs of both your business and your clients.

In this section, we’ll outline the process of creating a professional sales invoice, including selecting a template, adding necessary information, and finalizing the invoice for submission. You can easily create a professional and effective sales invoice by following these steps.

A business logo is a visual representation of your company, giving your invoices a professional and cohesive appearance. It also makes your sales invoices more memorable and distinguishable, particularly if you have many clients or invoices.

2. Add the Customer’s Contact Information

Including the customer’s contact information on your sales invoice helps establish a clear communication point and ensure that the invoice is delivered to the correct person. This information should include the customer’s name, company name (if applicable), address, phone number, and email.

It also demonstrates to your clients that you are serious about your business and pay attention to detail. Don’t neglect this important step in your invoicing process – include an invoice number on all your sales invoices.

Writing your goods or services clearly and accurately is crucial to creating a professional sales invoice. This helps establish the full scope of the work completed and ensures that you are properly compensated for all the products or services provided.

To write the goods or services in your sales invoice, start by describing each item or service, including relevant details such as quantity or duration.

Including any codes or abbreviations commonly used in your industry may also be helpful.

In addition to the description, include the cost of each item or service, including any applicable taxes or fees. Clearly state the total cost to make sure everything is clear.

5. Include the Payment Terms

Including the payment terms in your sales invoice is essential in establishing payment expectations with your clients.

By specifying the payment due date, late payment fees, and accepted payment method, you can help to protect your rights as a business owner and ensure that your invoicing process runs smoothly. This could include cash, check, credit card, or electronic transfer options.

6. Assign a Customer Code to Your Sales Invoice

Including a customer code on your sales invoice can be helpful in terms of record-keeping by differentiating client from client and tax compliance.

By assigning a unique identifier to each client, you can easily track purchase orders from goods or services provided to each client and ensure that you have all of the necessary documentation for tax purposes.

It can also help ensure clarity and consistency when reconciling invoices and tracking payments.

7. Add an Invoice date

Adding an invoice date in your sales invoice helps to establish the timeline of the work that has been completed and when payment is due, which is essential in ensuring that you receive payment promptly.

The top of the document is the most common place to include an invoice date.

It is crucial to ensure that the invoice date is accurate and up-to-date to avoid delays or misunderstandings.

In addition, it helps in deciding when to follow up with your clients regarding late payments.

By adding an invoice date to your sales invoices, you can improve the organization and workflow of your selling process and accounting department.

8. Calculate the Amount and Sales Tax

It is important to include the amount and sales tax in your commercial invoices to accurately reflect the total cost of the goods or services that you have provided to your client.

The amount should include the unit price of each item or services rendered as well as any applicable taxes or fees.

The sales tax is a percentage of the amount the government collects and is typically based on the location of the sale.

To calculate the amount and tax, you will need to determine the cost of each item or service and the applicable sales tax rate. You can then add the amount and the sales tax to calculate the total amount due, which should be clearly stated on your invoice.
