10 Best Free Invoicing Software for Error-Free Accounting in 2024

Invoicing tools have become vital and irreplaceable for everyone doing their own accounting.

To make sure you don’t waste money, we’ve explored and tested many tools to bring you the 10 best free invoicing software on the market! Some of these tools are completely free, while others offer a free plan with the possibility of upgrading for more extensive features. 

Still, all of them allow you to create invoices free of charge — because when you run a business, every penny counts.

Free invoicing software - cover

What is a good free invoicing app?

“A good invoicing app” has a different meaning for a freelancer, a small business, and a large company. That’s because each of them looks for different features in their invoicing tools. 

As someone who has been a freelancer for a while, I believe it’s not difficult to find an invoicing tool with every feature I need for free. However, large businesses with many clients looking to automate their invoicing completely will have a harder time finding something without investing money.

To help you determine which of the invoicing software on my list you should test out, I’ll go over the main criteria I used to create this list. 

Criteria #1: The “free” in “free plan”

Many invoicing tools advertise themselves as free when, in reality, they just offer free trials for their paid plans. After a week or two, you’d have to pay for a plan if you want to continue to use the software. 

When I was creating the list, I made sure that every software I named was actually free. Some of them do offer paid plans for more advanced features. Still, you can use the basic plans free of charge.

Another thing to keep in mind is that some free invoice tools have limits on the number of invoices you can send per month. I made sure to mention this, too because some of these limits could be a deal breaker for certain users. 

Criteria #2: Features

Not all free tools offer the same functionalities. I added tools with different features as I believe some users wish for more options while others prefer to stick to the basics. 

For instance, some invoicing software provides users with reports of their invoices. This is a pretty useful feature to have, as it gives an overview of profits and expenses. 

However, many people aren’t comfortable with software storing their sensitive information. So, I included a great number of online invoicing tools that don’t keep track of users’ previous records. Some of them don’t even require you to create an account! 

Criteria #3: Customization

Another important aspect I considered is the amount of customization users prefer. As a freelancer, having the option to add a logo and change the colors of my invoice to match my branding is irrelevant. I prefer something simple and ready for use. 

On the other hand, businesses with logos and branding could risk looking unprofessional if they don’t customize their invoices accordingly. So, they’d probably like more customization options. 

Hence, I made sure to include different options regarding the customization levels tools provide. You can find ones that suit your preferences and test them out.

Providing reports of your work is one of the ways to explain your prices to clients. Here’s more information about justifying invoices: 

Criteria #4: The level of automation

Some free invoice tools offer you the ability to create templates and save invoices for the next time you need them. Furthermore, with some, you can set recurring invoices. The tool then either reminds you when an invoice is due or sends it to a client automatically. 

Some invoice tools send your invoices to clients, while others require you to download and send on your own.

Moreover, some invoicing software can be connected to your card or an online payment system. This automates the process of sending and receiving money through invoicing.

However, not everyone wants the same level of automation. 

For me, linking my card to software I am still not familiar with is scary. In addition, having a tool send a recurring invoice without me double-checking it makes me uncomfortable. So, I prefer to download my invoices or send them to my clients via email without having to attach my card. 

On the other hand, I also understand this isn’t the most convenient option for businesses with many clients who send dozens of invoices a month.

All in all, you’ll see tools with different automation levels on the list. This helps you avoid wasting time on tools that don’t fit your needs.

Best free invoicing software for 2024

You can create a quality invoice with any of the following software. The best thing about them is they are completely free!

PayPal — best for invoice transactions

PayPal dashboard

PayPal is the most popular online payment service. It’s easy to use, has many integrations, and is adaptable to businesses of any size.

Once you create an account with PayPal, you have to go to the Send section and click on Request. You can then quickly request payment or create an invoice to send to your client.

I like that PayPal makes invoicing easier by allowing users the option to invoice recurrently. It saves the info in the invoice so you can request payments from this person or business more quickly next time.

Then, when you create an invoice, PayPal will automatically add up all of the items on your list. You can also add taxes and enable your clients to give you tips. 

PayPal invoicing
Invoice payment options

Another option that I benefited from when I was a freelance content writer was the partial payment feature. I usually asked my clients to send me at least a part of the final payment before I began my work. 

With this option, my clients knew exactly how much my services cost in advance, and they were able to make a minimum payment before my work started. Then, once the job was done, they could reimburse me for the completed project. 

Key PayPal pro:

  • Easy to create an account and attach payment methods

Key PayPal con:

  • Your account is connected to your phone number

💡 Clockify Pro Tip

Paypal is one of the most popular payment apps. Find the full list of best payment apps here:

ReliaBills — best for small business invoices

With the free plan, you get to generate unlimited invoices for an unlimited number of clients with unlimited amounts of emails. Their paid plan offers more features and is available for $24.95/month.

ReliaBills enables you to create customized invoices with your brand’s colors and logos included. Afterward, you can import them individually or in bulk. Once the client receives an invoice, they can approve it with just one click or ask you for a follow-up.

Reliabills invoicing
ReliaBills offers plenty of options for invoices

I like that ReliaBills allows me to generate invoices quickly by enabling me to save various info about my customers or products. I was able to save the complete invoices and clients I work with regularly. Furthermore, I got the option to save the types of services I provide as well as their pricing. 

Now, whenever I create an invoice, I use saved client information and just choose the type of service I provided from my list. ReliaBills then inserts all the info I previously saved. It’s a perfect invoicing software for small businesses with recurring clients.

Key ReliaBills pro:

  • Offers options for both taxable and non-taxable discounts

Key ReliaBills con:

  • Not enough invoicing options for larger businesses

  • Outstanding invoices,

  • Revenue categorized by clients, and
  • Sales vs. purchases comparison.
Hiveage invoicing
Options for Hiveage invoices

I think Hiveage stands out from other invoicing tools due to the number of details it allows users to add to invoices. I immediately noticed I could add so much info to my invoice, such as: 

  • Date, 
  • Attachment, 
  • Links, and 
  • Tags. 

As a content writer who mostly works in Google Docs, having the option to link to the article I am invoicing for is such a time saver. This option also removes confusion a client may have about what article I am referring to in my invoice.

Key Hiveage pro:

  • Shows profits and losses

InvoiceOcean — best for recurring invoices 

Invoice ocean

InvoiceOcean promises professional-looking and accurate invoices in under 30 seconds. It automates the process of generating invoices by offering pre-defined fields and creating templates from invoices you previously created. 

However, InvoiceOcean only offers 3 invoices a month. You have to switch to a paid plan for more invoices (starting from $7.2/month).

Invoice ocean invoicing
Generating an invoice in InvoiceOcean

A great option InvoiceOcean’s invoices have is adding quantity and quantity units on invoices. I used to have a client for whom I had set prices for each article. This option speeds up my invoicing as it allows me to add the number of articles I wrote, choose the quantity unit (pieces, in my case), and the software automatically sums up the final cost, including taxes. 

You can also add a discount option to your invoices. Simply add the discount percentage, and Invoice Ocean calculates the final cost on its own. 

Moreover, InvoiceOcean adds pre-defined VAT rates. You can choose the regular 20% or add your own VAT rate, and the software automatically calculates the taxes for your services.

Key InvoiceOcean pro:

  • Comes with step-by-step video instructions

Key InvoiceOcean con:

  • Offers only 3 invoices a month for free

What’s new in InvoiceOcean

For its last update (2021), InvoiceOcean added JSON format to the price list. 

In addition, the tool introduced numbering on their invoices. Users can change item orders on existing and new invoices. 

InvoiceOcean is available for: Web, iOS

Simplybill dashboard

Simplybill is a cloud-based invoice creator that helps you generate and send out up to 3 invoices, as a part of the tool’s free plan. Paid plans start from $5/month.

Invoicing services, time, and products with Simplybill

This invoicing tool is great for freelancers who charge by the hour. Apart from the usual information, it allows you to indicate each of the services you’ve provided to the client, as well as the hourly rate for each service.

When I charge by the service, I like to use the Service Invoicing section due to its simplicity. I just need to add the description of the service and the cost. 

On the other hand, if I charge by the hour, I will use the Time or Product Invoicing. In this section, you can add the quantity of the number of hours worked as well as your rate. Simplybill then calculates the final cost of your services. 

Key Simplybill pro:

  • Shows monthly paid and unpaid invoices

Key Simplybill con:

  • Allowing the customers to pay the bill via PayPal, by clicking on the PayPal button provided.

Adding invoice items in Street Invoice

One thing I love about Street Invoice is that I can quickly determine my profit for each item. Aside from the name, quantity, and price of a service, I can input its cost (my expenses for the item). Street Invoice then calculates my profit for the item by subtracting its cost from its price. 

Your client will only see the total price of your service, while you can have an overview of your profit.

Zervant — best for beginners invoicing

Zervant dashboard

The free version of Zervant software comes with everything you need to create a detailed invoice. However, it’s limited to 5 customers and 5 invoices per month, so, it may not be the best option for larger businesses. Paid plans go from £10/month (around $13) or £8/month (about $11) if billed annually.

Zervant is one of the best invoicing tools for beginners. Its interface is simple and interactive, and the dashboard contains all the relevant info about your previous invoices.

You can enter company details that appear on every invoice, attach your logo, as well as add your card or PayPal account. Moreover, you can change the colors on your invoices to better match your logo.

My favorite part about working in Zervant is the checklist. When you begin creating an invoice, you’ll see a checklist that reminds you of the relevant info you need to add.

Zervant’s checklist for invoices

As soon as you are done with completing each section of the invoice, that step in the checklist is marked as completed. So, you don’t have to worry about missing a step, as Zervant’s checklist contains everything you need to create a good invoice.

Another option is to add products and their quantities to your invoices. ZipBooks then sums up your items.

ZipBooks invoicing
ZipBooks Invoice Quality Score rates your invoices

My favorite ZipBooks feature is the Invoice quality score. It scores the quality of your invoices based on different parameters, educating you on how to create a high-quality invoice.

For instance, ZipBooks found that customers are more likely to buy again if a business has a logo on their invoice. What’s more, thanking customers for their purchase makes them more likely to recommend you. 

ZipBooks also found that accepting credit cards helps businesses get paid faster. So, when you add these aspects to your invoice, your score improves.

  • Basic financial reports 

Key ZipBooks con:
