How to Invoice as a Consultant?


Keeping track of billable hours and billing clients for your time is an important aspect of running a consulting firm. 

To get paid for their work, consultants should keep meticulous records of the time they spend on each project and invoice their clients on a regular basis.

Consultants must create professional invoices that clearly outline their services, the number of hours they worked, and the amount owed. 

Here’s a step-by-step guide to invoicing clients as a consultant:

Invoicing tips for consulting services

Track Your Hours:

In the consulting industry, billing clients by the hour is fairly common. If that’s the case with some or all of your clients, it’s critical that you develop a system for keeping track of your hours. Make sure the system works for you and that you’ll be able to stick with it in the long run. 

It’s critical to keep track of every billable hour, so you don’t miss out on any potential revenue. The first step in invoicing as a consultant is to keep track of your hours so you can bill clients hourly.

Include a Header

When creating your first consultant invoice, make a basic header that will appear on all subsequent bills. 

Include the following in the invoice template’s header:

  • The logo of your company
  • Contact information of your company, including your name, address, phone number, and email address
  • Include the word “invoice” in your header so that clients can see what the document is about at a glance.

Add Your Client’s Contact Details

You’ll need a space on your invoices below the header to fill in the client’s contact information. Double-check that the correct point of contact is listed on every bill you create. 

If your clients are larger corporations, your invoicing contact will most likely be someone from the billing department rather than your regular business contact. Taking the time to double-check the billing contact can help you get paid for your services more quickly.

Include The Invoice Date

Below the client’s contact information, write the date you’re preparing the invoice for. This will make it easier for both you and the client to file the invoice for bookkeeping.

Number Your Invoices

Every invoice you create should have its own unique number. If you number your invoices, you and your clients will be able to refer to a specific invoice if questions arise quickly. 

A consistent numbering system also aids in the filing of invoices and the organization of your records. The most straightforward method of numbering invoices is sequential. So, for example, your first invoice could be Invoice #001, and your second could be Invoice #002, and so on. You can create a numbering system that includes the invoicing date if you prefer. In the top portion of the invoice, write the invoice number.

Clearly List Your Services

Make a detailed list of all the services you’ve provided, including the following:

  • Each service is given a brief description.
  • The amount of time spent working
  • The hourly wage rate
  • A subtotal of each service’s charges

It may be beneficial to organize this information into a table, with each piece of information having its own column.

State Your Payment Terms

On every invoice you send, include your payment terms. It’s also great to go over your payment terms with each client before signing a contract so there is no confusion when sending your first bill. 

The payment methods you accept should be listed in your payment terms, and they can include any of the following:

  • Checks
  • Cash
  • Credit card
  • Bank transfer
  • Online payments
  • Mobile payments
  • Recurring payments

Your late payment policy should be stated in the payment terms section of your invoice. List the details of your late fees here if you plan to charge them for late payments.

List the Payment Due Date

Make a note of the payment deadline on your invoice. Make this section of your invoice stand out so that clients don’t miss it. Use bold fonts or different font colours to make it stand out. Instead of vague deadlines like “Payment Due in 30 Days,” it includes a specific payment due date. Giving the exact due date can help you avoid misunderstandings and get paid faster.

Add the Total Amount Due

Include the total amount due on the invoice, with any applicable taxes. Much like with the payment due date, make the total due section stick out on the page with larger, bolder, or more colourful fonts.

Getting paid faster is all that matters after the completion of any work. Besides learning how to invoice as a consultant, check out the below-mentioned invoicing tips to avoid delays in your payment process.

Monitor the working hour

Tracking working hours is vital for speeding up payment procedures. Consultants need to keep track of the productive hours so that they can invoice properly. As we have already discussed, most consulting services bill their clients on hourly rates. Therefore, it is essential to keep track of the productive hours.

Do not delay in creating invoices

There is no harm in sending out the invoices to your clients as soon as you’re done with your projects. Sending the invoices immediately speeds up the payment process as it reduces the chance of getting overlooked by the clients.

Make payment methods flexible

Flexible payment methods like accepting checks, cards, bank transfers, online payments, etc., make it more convenient for clients to pay. Keeping diverse payment methods eases up the client’s job, and the payments get settled quickly.

Request for deposits

In some cases, where you can understand that it would take months to complete, it is safe to ask for a certain deposit amount. This would help you to carry out your business expenses with a steady cash flow. It also avoids the risk of an economic downturn due to sudden project cancellation.

Be polite and friendly while you follow up on delayed payments

Follow up for delayed payments. Be polite while you send out friendly emails or make phone calls. As per various studies, a thank-you note at the end of a follow-up email maintains cordial business relationships and gets your invoices paid faster.
