Invoicing can take up a huge chunk of a business owner’s time. Invoicing apps make it easy to create, send and track invoices so you get paid faster. The best part is that they’re accessible on mobile devices for on-the-go invoicing.

Whether you are looking for a paid invoicing app with plenty of features, all-in-one accounting and invoicing software, or a free invoice generator that makes your small operation look more professional, there is an invoice app for you.

What to look for in a billing and invoicing app

Finding the right invoice app for your business can feel overwhelming, especially as new invoicing tools are added to the market or old ones are updated with new bells and whistles. Before you begin comparing options, consider what you want in a billing and invoicing app.


Some apps can handle all your accounting needs, including invoicing and monitoring your cash flow. If you choose an app that is just for invoicing and billing, though, it should integrate with whatever accounting software you already use. Otherwise, you run the risk of making costly errors as you transfer information from one program to the other, and of losing time that could be spent on other parts of your business.


More features do not automatically mean a better invoicing tool, especially if you end up paying for features you never use. However, you don’t want to save money by sacrificing functions you genuinely need. If you pay for invoicing software, look for an app that includes these features:

  • An invoice generator with customizable templates for professional branding
  • An easy way to follow up on unpaid invoices
  • Client profiles you can save, rather than manually entering data every time
  • A way to store and send receipts for expenses that a client must reimburse
  • Connectivity to multiple payment gateways
  • Online invoicing

Ease of use

As a business owner, you want technology to streamline your tasks, not make them more complicated. You don’t want to search for your client list every time you open the invoice generator or spend hours uploading receipts when you are sending a bill for reimbursement.

The invoicing software you have used in the past and your familiarity with new technology will influence how complex these apps feel. Play around with a few to find one that feels easy and intuitive to use.

You should also look for an app that is easy to use on your mobile device as well as via web browser to make invoicing on the go simple. Make sure you have easy access to customer support in case you have questions down the road.


Budget is always a concern for business owners, especially those just starting out. Luckily, there are invoice apps available in multiple price ranges, including several that are free to use. Many paid options offer a free trial, allowing you to test the software before committing to a monthly or yearly plan.

For many invoicing apps, the structure of your business will affect the ultimate cost. Some apps charge a flat fee for use, while others charge by the number of invoices you send per month or the number of client profiles you store. Your billing history can help you determine which invoice app is the best fit for your business’s budget.
