Everyone likes to get paid. The easiest way for a business to get paid is to invoice a client. However, starting an invoicing system or even creating an invoice can be a daunting task. After reading this blog, you will learn about invoicing best practices including what is on an invoice and the best invoicing software.

What is an Invoice?

An invoice is an itemized document that is presented to clients for goods and services rendered. It differs from a receipt in that a receipt shows that a payment has been made while an invoice shows that payment is needed.

Invoices allow a company to account for any payments due or if they are outstanding. This assists with keeping correct records and will help with financials in the event of an audit or if any investors have questions.

Parts of an Invoice

When drafting your invoice there are several key items that should be there for best invoicing practices before it goes out to a client.


Having dates on an invoice is an important piece of information not only for you but for the recipient of the invoice. Dates let people know when the invoice was issued, and what it is for. There should also be a due date listed on the invoice so people know when payment is due so they don’t incur late fees.

Invoice Numbers

A clear invoice number, also called a reference number, corresponds with a customer’s account and can identify a specific transaction. Invoices should be a unique number, not used for anything else. This also helps billing and collection departments easily find outstanding payments or if someone was double-billed and follow up with them.

Most invoicing systems will have a program that will automatically create an invoice number so you don’t have to manually make and remember them.


A clear description gives the client more information about what the payment is for and gives them paperwork for their records. It can show what service was provided and can be as detailed as you wish.


Make sure to address the invoice to a specific person in the company, preferably the person who will be paying the invoice or the name on the account. Then it will go to a specific person and not just a department. Your invoice is less likely to get lost and more likely to be paid on time.

Payment Info

One of the most important items to include on an invoice is payment information—how does someone pay their invoice?

Some items you should include are:

  • The total amount due,
  • The terms of payment (if there are any)
  • How someone can remit the payment
    • Cash, check, credit card, or electronic payment like PayPal or Venmo

Another item to clearly spell out is what the late fees are and when they apply. Then there won’t be any surprises for the client on what will happen if they are late with payments. Also if they balk at paying extra charges, then you have documentation that they were informed of the late fees and procedures.


Branding distinguishes your product from any other. Visual branding references include company colors, specific fonts, and your logo.

Using your branding helps inform the client who the invoice is from so they know where to send their payment. It also shows that it is an official document from your company and not a scam.
