What Is the Purpose of an Invoice?

An invoice is a document given to a buyer by a seller to collect payment. Invoices include the cost of products or services rendered, the associated cost, the due date to receive payment, and any other pertinent payment details, such as available payment methods. Understanding invoices helps you keep a clear line of communication between you and your customers and helps ensure best practices for quick and efficient payments. Invoices serve an essential purpose in small business accounting. Invoicing demonstrates a client’s obligation to pay for your goods or services. This verifies, in writing, the payment agreement between your business and the client. Good invoices set your payment terms and enable you to get paid faster.

What Is the Purpose of an Invoice?

The most basic purpose of an invoice is to offer a record of sales so a business can get paid by its clients. But invoices serve other essential purposes, some of which might not be immediately obvious. The following are the invoices’ key purposes:

1. Bookkeeping

Invoices make a record of all your sales and so are helpful for bookkeeping purposes. Invoices are invoice documents that provide documentation of your business’s financial history. They track all the revenue from your business through sales and can help you gauge your profits and cash flow. This is where we come into place! We highly recommend keeping invoices and any paper trails to better comply your information during tax season.

2. Tax Records

Your sales invoices serve as essential documentation to validate the information you report on your annual tax filings. The IRS recommends that all small business owners maintain daily records summarizing their business transactions, including invoices. 

3. Legal Protection

Invoices help protect small businesses from false lawsuits because invoices provide details of the services you provide to your clients and the timeline for completing the work. An invoice also records the amount a client agreed to pay you for your services, and signed invoices can serve as legally binding agreements.

4. Marketing

Records of your invoices can help you develop marketing strategies. You can analyze your invoices to identify peak times when your services are most in demand, the most popular and least popular services you offer, and other trends in your business. Once you identify these trends, you can develop intelligent marketing strategies based on the data to grow your business.

5. Tracking Inventory

If your business keeps inventory, sales invoices can help you track how much inventory you have and predict how much you’ll need in the future based on past sales. You can use invoicing software to track inventory based on your invoices automatically, or you can develop a manual tracking system for invoices on your own.
