Getting started: What are invoices

What is an invoice?

A basic invoice is an itemized list of services provided or goods shipped, the price, and the terms of sale. It’s sent from a business to a customer or supplier, demonstrating an obligation to pay for those goods or services.

An invoice usually includes three main items:

  1. An amount to pay
  2. The timeframe for payment
  3. Any amounts already received for this sale (if applicable)

Invoices play an essential role in business accounting. They inform customers what they owe, and also help to track sales and inventory, do sales forecasting, and keep tax records. All of these things are crucial to keeping your business in good standing.

What is an electronic invoice or e-invoicing?

An e-invoice is defined as “the interchange and storage of legally valid invoices in electronic format only between trading partners.”

E-invoices are digital but hold the same legal significance as paper invoices. They can prove compliance or even act as tax originals. An e-invoice should be compliant, clearly state the goods or services received, and be executable based on the invoice payment terms.

Invoice payment & billing

How to pay an invoice

Whether you run a business or fly solo, invoice payments can cause headaches. Especially when it comes to international invoices.

There may be a discrepancy between the sum of money listed and what you thought you had to pay. This can be due to the conversion rates used. The invoice payment method you choose can also make a difference in fees, speed, and practicality.

This article will cover how to pay domestic and international invoices on time, using different methods. You can also find some tips on how to get a customer to pay an invoice.

How long is a billing cycle?

A billing cycle is the period of time that passes between sending one invoice, and sending the next. A typical use for setting a billing cycle is when your business offers a repetitive service.

The length of a billing cycle is not fixed and can vary between companies. While many companies use a monthly or 30-day billing cycle, the standard range is typically between 20 and 45 days. However, different companies may have their own billing cycle, such as a 28-day period or a calendar month.

Past due invoices & how to manage them

Invoice late fee wording: How to charge interest and late fees

Late fees can encourage on-time payments. They are often included in the ‘terms’ section of an invoice, and they detail when late fees are applied and the amount.

A simple example late fee phrase could be:

“Invoice payment is due within 30 days. Please be advised that we will charge 1% interest per month on late invoices.”

If the customer doesn’t pay, you can then follow up with a late fee letter. The late fee letter should be polite, accurate, informative, and based on the terms of the original invoice.

The full article will cover what to include in your late fee letter, including how much you can charge and top tips on how to deal with late payments.

How to collect past due invoice

An invoice is past due when the invoice payment is late. Once an invoice is past due, you should inform the customer of the overdue payment. If your business has late payment fees for past due invoices, then you can also include these fees in the payment request.

Example of a first past due payment letter:

Dear Customer,

This is a friendly reminder that we have yet to receive payment on our last invoice. The invoice dated XXX, with reference number XXX, was due on XXX.

You can find a copy of the original invoice attached. Please let us know when we can expect payment.

Kind Regards.

But, the process might not stop there. You could have to spend more time trying to collect your payments.
