What Invoice Means: A Definition

Let us start with the basics first and understand what invoice means.

An invoice is a commercial document that is presented by a seller to their buyer to collect payment for the goods and services offered. It is an important part of any business accounting process and sets your payment terms with the seller.

It is a legally enforceable agreement between two parties and provides documentation of the goods and services transacted and the payments that are due.

An invoice can be made by any type of business. However, they are most commonly used by businesses that make large purchases. Invoices are also used by contracting service providers, such as educational services and construction. Freelancers who offer hourly services also use invoices to request payment from their clients.

Oftentimes, the terms invoice and bill are used interchangeably. Although there is a slight difference between the two, they are both used for different purposes.

While invoices are used to request payment from your customers, bills refer to the amount of money a customer owes to a business for goods and services provided. Bills are standardly used in retail businesses such as restaurants and eating joints.

 

What are the Different Types of invoices?

Now that you know what an invoice means, let’s take a look at the different types of invoices that businesses in different industries use. It also depends on the kind of transaction and the legal framework within which you operate.

Here’s a list of different kinds of invoices that are commonly used:

Standard invoice

A standard invoice is the most basic invoice that is issued by a business to its clients. It records the sale and seeks to collect the payment from the buyer of the goods or services.

When to use:

  • This invoice is used while collecting payments from one’s customers.

Commercial invoice

A commercial invoice is used when a business is selling its goods and services internationally and is mostly used for determining customs duties. The information in this type of invoice includes the quantity of the shipment, its weight or volume, total value, description of the goods, and the packaging format.

When to use:

  • While shipping goods internationally.

Credit invoice

Also known as a credit memo, a credit invoice is issued by a business in lieu of a discount that it owes to its customers. This is also issued when a previous invoicing error needs to be corrected.

This type of invoice always includes a negative number. For instance, if you owe your customer a refund of INR 1,000, the total of the invoice will be -INR 1,000.

Debit invoice

A debit invoice is issued when your business needs to collect an extra charge from its customers. These are mostly used by small businesses to make minor corrections, like working additional hours on a project and billing for the extra amount.

Mixed invoice

This type of invoice combines the credit and debit charges on one single invoice. Mostly used by small businesses, it is used to reduce the amount your customer owes for one project while increasing the amount due for another project.

When to use:

  • When you are combining your credit and debit items in a single invoice.
  • When you need to decrease the amount and later increase it.

Pro forma invoice

This is a provisional invoice that is sent to one’s customers before a sale is actually made. The purpose of a pro forma invoice is to provide your customer with an estimated cost, which may have to be altered once the goods are provided or the project is completed.

When to use:

  • When you have confirmed a large order with a customer.
  • While declaring the value of goods to the customs.
  • While bidding on a project.

Recurring invoice

As the name suggests, these invoices are created to request payments that occur regularly. These come in handy in the case of repeat transactions and are mostly used by companies that operate on a subscription model.

When to use:

  • When you offer goods and services at fixed intervals, such as weekly or monthly.
  • When you collect payments in instalments, such as in car dealerships.

Timesheet invoice

Timesheet invoices are used when you need to bill your customer according to standard work hours or fixed pay rates. These are mostly used by lawyers, advertising agencies, and business consultants.

When to use:

  • When you are offering services by the hour.

Interim invoice

Interim invoices are used when a transaction involves major milestones and the client and business have agreed to multiple payments.

These invoices are especially helpful for small businesses to manage their cash flow as they work on projects over longer durations.

When to use:

  • When working on projects that take several months to complete.

What are the Components of a Standard Invoice?

Now that we have gone over what invoice means and the different types of invoices, let’s take a look at the components of a standard invoice.

Just like any other accounting document, the right information can make a lot of difference when it comes to getting paid correctly and on time. Even the slightest error may lead to your payments being impacted.

Here is a list of some ‘must-haves’ in a standard invoice:

  • Unique invoice number: This is a unique number that helps identify and track each invoice for easy reference. This may be a combination of numbers, special characters, or letters.
  • Invoice date: This is the date of issue of the invoice.
  • List of goods or services: This list is indicative of descriptions such as items, quantity, price per unit, etc.
  • Tax or discounts: This detail offers information about the applicable taxes and discounts, such as GST, VAT, or shipping fees.
  • Total due amount: This is the final amount that the customer has to pay after deducting the taxes and discounts.
  • Due date of payment: This is the day by which the customer must pay you in totality.
  • Payment terms: These terms are essential to define the payment methods, currency, late fee charges, and other conditions regarding payments.

Importance of invoices in business

Irrespective of the size and scale of your business or the industry that you operate in, invoices are critical to keep your business running smoothly.

While the basic and most important purpose of an invoice is to maintain a record of your sales to get paid on time, there are other essential purposes that invoices serve.

Let’s take a look at why invoicing is important for a business:

Better cash flow

An invoice serves as formal documentary evidence for payment. When served with information about the goods and services supplied, the due amount, payment terms, etc., you are likely to receive the payments in time.

This leads to an improved cash flow situation, helping you meet your daily obligations while maintaining stability in the business operations.

Record keeping

Invoicing is essential to maintain a transparent record of all your sales transactions. They help track your revenues through sales and let you assess your profits and flow of cash. This way, they help document the financial history and health of your business.

Taxation

Invoices are an important instrument to help you file your taxes. When you have a comprehensive sales summary through invoices, you exactly know how to calculate your sales tax liabilities, claim deductions, and comply with GST. This also helps you calculate your tax refunds and pay your taxes on time.

In the long run, this is essential to control your tax flow and stay assured that you will not be handed large tax bills.

Overall business profitability

Invoicing helps you assess your cash flow through sales. This gives you a better picture of which goods and services are selling and those that are not.

This helps you make better investment decisions. You know where to focus more and where to course correct. Overall, in the long run, this helps in streamlining your processes and making your business more productive and profitable.
