If you own and operate a small business, then you know that creating invoices is one of the most mundane yet incredibly important tasks you need to do. 

Invoices are important for you to be able to keep a track of what services or products you’ve supplied your customers, and what they owe you in return. 

These invoices will also be helpful when it’s time to pay the tax man since they will clearly show what income you’ve had, and help you calculate how much tax you need to pay after tax deductions. 

Invoicing does not need to be such a chore, considering all you need to do is start using invoicing software to automate the process for you. 

We’ve compiled our picks for the best invoicing software for small and growing businesses to help you make the right choice.

What to look for in an invoicing software

Essentially, invoicing software is a tool that makes invoices and credit notes for businesses in a format that is accepted by customers and other businesses. 

However, good invoicing software does a lot more than create invoice templates. Let’s take a look at what features you’d want to find in the best invoicing software.

Ease of use

Technology is meant to make our lives easier, not harder. That applies to automation technology that we use to help run aspects of our businesses as well. 

Considering the task of creating invoices is already boring and repetitive, the last thing you want is to use invoicing software that is complicated to use.

Choose invoicing software that is easy to use and comes with an easily navigable user interface, or in other words, tools with smartly designed UI/UX. 


You ought to invest in invoicing software capable of integration with other applications for project management, time tracking, and more. That way, you can streamline the way you run your business from a single dashboard. 

An invoicing tool with an in-built payment gateway is a great integration to look for.


While yours may be a small or medium business right now, you may want to scale your business up as it becomes more profitable and as your client base grows. Who knows, that may well be in the near future! 

This implies that you will need an invoicing tool that is capable of scaling your business and handling the creation of more invoices at a faster pace every day.


This is what often breaks the camel’s back. While some invoicing tools may have great features, it is difficult for small businesses to afford them if they aren’t reasonably priced, if not completely free. 

Even if you need to pay, look for software that offers a hands-on trial period, so you get the look and feel of the tool before entering into a contractual agreement with them. 

Luckily for you, we’ve chosen tools that tick most, if not all, of these boxes.

The best invoicing software for your business 

We’re not just going to take you through our top picks for invoicing software, we’re also going to break down their best features and their cons, so you know just what to expect.
