Today’s Entrepreneurial Workforce

The independent workforce is increasingly growing. Developers are also providing more add-on services as they go based on client needs. As a result, there just isn’t enough time for professionals to learn the backend of running a successful business: namely, accounting and finances.

These invoice templates will help guide you to inputting your hours and materials in a professional manner—so that you can keep your cash flowing.

What should I include on my developer invoice template?

Is invoicing new to you or just a little bit convoluted? Here’s what to include on your developer invoice template to keep getting paid the right amount and on-time—every time!

A professional invoice will communicate to your client that you’ve done this before, and that your services are trustworthy and reliable. From the detailed descriptions and totals to payment policies and branding, your invoice is an extension of your software development business—so you should take your time when creating it.At a minimum, here’s what to include in your contractor invoice.


Your business name and logo

Your business name is a foundational element of a professional invoice. It identifies your business and establishes your brand. Adding a business logo will provide a professional touch.


Business contact information

Including a seller contact helps your customer know how to contact you with questions about the invoice. It also puts you as the point of contact for all future work.


Invoice number

Your business name is a foundational element of a professional invoice. It identifies your business and establishes your brand. Adding a business logo will provide a professional touch.


Payment terms

Small businesses mainly use: due on receipt, net-15, 30, and 60. For example, net-15 days tells your client that the invoice is due 15 days after the invoice date. The invoice payment terms depend on your relationship with your customer, common practices in your industry, and your cash flow needs.


Due date

The combination of the Invoice Date and Payment Terms provides the Due Date. A due date clearly indicates to your client when they should pay.

Pro tip: Setting up payment reminders can help keep your client on schedule to pay the invoice.


Bill to (who's going to pay)

Provides the name and contact information of the person the invoice is intended for (aka your client)


Product or service detail

Similar to your Statement of Work (SOW), here’s when you specify Description, Quantity, Rate, Amount, and Subtotal. The more detailed this section is, the better clarity you provide to your client—who needs to understand what they are paying for on the invoice.


Sales tax

Depends on the jurisdiction and business type. Check the local tax bureau to include the appropriate tax amount on your invoice.

Pro tip: Use an invoicing app like TrulySmall™ to manage business transactions, change tax settings easily, and just make doing your accounting and taxes more easy and efficient.



Provide discounts to your clients to give them initiative to pay earlier, for example. If you are going that route, include the number here as a percentage or actual amount.



A simple, personalized note will bring even more clarity to your client and leave a long-lasting, positive impression with the client—which should increase the chance of your invoice getting paid faster. Other details can include payment instructions (i.e. Venmo, e-Transfer, or bank cheque), discount details, warranty information, or anything else relevant to the project or business opportunity.

When should I send my freelancer invoice?

Software developers complete many different types of projects. These range from large website builds and mobile app development to ongoing website maintenance. Many of these projects are built from scratch—which are often more costly.

Deciding how to charge depends on the project work because not all development work is the same. While some clients are looking for an eCommerce website built from scratch, others may just need a simple website with a few pages. Understanding the difference and choosing how you want to charge is the first step before you decide to include it on your terms on your developer invoice.
