As a professional, you bring your experience, skill, and knowledge to everything you do for your clients. That means you need to use clear, organized invoice templates that include enough detail to ensure your clients understand the advantage of working with you. Your invoice also serves as a reminder of the work you have done long after the project is over – so your clients will remember to call you again, as well as refer you to their friends.

Sending organized, well-designed invoices also instills confidence and credibility in the services you provide. You are an expert in your field – make sure your invoice reflects your skill and professionalism.

When is the right time to send an invoice to your clients?

The right time to send an invoice can vary with the job and the client. Some professionals wait to send an invoice at the end of a job or project. As an independent business owner, you need to keep the revenue coming in, so many professionals ask for payment up front, or for a percentage of the estimated cost up front, with the remainder on completion of the project.

If you have been retained for an extended period of time, discuss the option of invoicing monthly, or at certain significant milestones in the project.

Handy invoicing tips for professionals

Keep a record of your work with numbered invoices

Numbered invoices help you keep track of how much money is coming in, and shows clients you have an organized system in place. You can also assign a job code if your work for that client is going to be spread out over a long period of time and involve several invoices.

Always include a ‘payment due’ date

This really does encourage on-time payment. It’s a clear indication of when you expect payment without sounding too aggressive. It also helps you predict your future finances.

Include professional recommendations

Include a few lines to describe any future services you think would be helpful for your client. It lets them know you are thinking about their best interests and are providing them with your expert knowledge. It also encourages repeat business – which is always a good thing!

Change your payment terms

We live in an automated world where people are used to paying for products and services right away. You might consider shortening your payment terms from 30 days to three weeks, or even 15 days. You never know – your clients might appreciate the opportunity to pay faster and get the money off their books.

Don’t be shy about following up

If a payment is late, follow up immediately. The payment might have just slipped your client’s mind, or they may be bogged down in another matter. Be friendly and polite and they should appreciate the reminder. It also shows your professionalism by having a system in place to track your revenue.
