Let’s dive in!

What Are Service-Based Businesses?

Service-based businesses provide services rather than goods for their clients. This encompasses a huge range of companies, including (among others):

  • Consulting businesses
  • Healthcare services
  • Maintenance and repair services
  • Legal services
  • Coaching services.

Service-based businesses consist of individuals or teams of people providing their time and expertise to cater to the needs of their clients. Instead of being paid based on products provided, these businesses are paid for services rendered.

Due to the lack of tangible goods, documentation in the form of invoices is particularly important. It not only helps to establish clear expectations, but it also opens the way for the development of strong, transparent, and mutually beneficial relationships with your clients.

Each encounter, driven by a well-structured service invoice, displays service providers’ professionalism and commitment, fostering a culture of trust, satisfaction, and long-term involvement.

What Are Services Rendered Invoices?

If you’re running a service-based business, you must know how to write an invoice for a service.

Service invoices usually contain a breakdown of:

  • What services were provided
  • The price for each service
  • The overall time spent
  • The full cost.

Creating one of these invoices sounds easy, but there’s more work to it than you might think!

Not only do you need to include all the necessary information, it needs to look appealing so that it reflects well on your company. There’s also a ton of follow-up — you’ll need to keep track of payments, answer queries, and deal with disputes and late fees.

To make the process a whole lot easier, businesses can use a services invoice example like a template to ensure everything necessary is included. This gets rid of worries that you’ve missed something important and lets you effortlessly create a record of the transaction between your business and the client.

These transaction records are essential when it comes to tax time, and also help avoid drawn-out disputes.

If your invoice is precise and professional, the client will feel confident they fully understand exactly what they’re paying for. It also means if there’s anything on the invoice that they disagree with, they’ll be able to query it immediately, and any confusion can be quickly and easily cleared up.

7 Tips to Write an Effective Services Rendered Invoice

Following these seven tips can significantly improve and streamline the process of billing for services rendered, making sure you maintain a good cash flow and great relationships with your customers.

To save yourself a ton of time and hassle, consider using an invoice template for services rendered, like one of the templates on offer from Bonsai.

All of our templates are fully editable with the ability to add custom branding (such as your logo or brand colors), so you can instill confidence in your clients while encouraging prompt payment!

1. Make Sure Your Contact Info Is Complete and Clear

Ensure your contact information is easily visible on your invoice for services. It should include:

  • Your name
  • The name of your business
  • Your business address
  • Phone number
  • Email.

Your business name needs to be at the top — if you’re a solo operator, just include your own name. This is also the place to include your company logo, to ensure your branding is easily seen. If you have a business statement, put that directly below your name.

Ensure you include all the details of the client you are billing.

2. Assign a Unique Invoice Number and Date It

To ensure you and your client can easily track your transactions, ensure each invoice is assigned a unique number. This makes identifying payments easier and also simplifies things in the event of a dispute.

Dating your invoice for services rendered is also essential as it creates a timeline for payment, and sets the invoice apart from others you may have sent to the same client.

3. List Out the Services You’ve Provided in Detail

Your client wants to see exactly what services they are being billed for. In this section, you need to break down:

  • Each type of service that was provided
  • The date it was provided to the client
  • The specific rate for the service
  • The total hours worked.

Table formatting is a good option for this section, as it clarifies the specific price for each service.

4. Break Down the Prices for Each Service

To avoid any confusion, you need to have clarity surrounding the different prices for each service. For example, a plumbing company may charge different rates for the hours worked by a fully skilled tradesman compared to an apprentice.

Ensure the rate for each service is clearly and transparently stated, as well as the quantity or hours provided. Make sure you clearly display and emphasize the total amount that is due.

5. Specify When the Payment Is Due and the Terms

Set payment expectations by clearly stating when the payment for services is due.

Make sure you clearly state any terms of payment, such as late payment fees to encourage the client to pay promptly.

6. Mention the Ways You Accept Payment

Your services rendered invoice should also include the payment methods you accept — this could include credit card, check, cash payment, or online banking payment.

This ensures your client has all the necessary information to pay you promptly and streamlines the transaction process.

If you have a preferred payment method, state this clearly to encourage your client to use that method. If you include a surcharge for certain payment methods, such as credit card payments, ensure that is clearly stated.

7. Keep the Invoice Looking Professional and Organized

Ensuring your invoice for services rendered is well-organized and professional-looking improves your business credibility — this is particularly important if you’re just starting out!

An ambiguous invoice with amateur graphic design is a surefire way to make your business look unprofessional!

No matter which type of service you’re offering, using a clear, organized format to display your services rendered is one of the best things you can do for your business. It ensures all the important details are provided, which makes billing and payment easier for both you and your clients — using a template can streamline this process even further!
