The Best Free Invoice Software to Streamline Your Billing Process

Everyone likes getting paid, but no one likes sending invoices. Filling out invoice templates, calculating costs, adding key details, and making sure it gets to the right recipient is a chore, and that's often just the beginning of the process—if it isn't paid, you'll need to chase clients and request payment.

There is an easier solution, though. Invoice software can do all of the legwork for you, automating many of the most time-consuming steps, and leaving you with more time to focus on the things that matter. If you stick with free invoicing software, you'll get all of those benefits without the burden of adding an additional subscription charge to your monthly outgoings.

What is an Invoicing Software?

As the name suggests, invoicing software is a program built for the purpose of sending invoices. These programs can integrate with an existing Business Account to automatically generate and send invoices, giving business owners a simple and fast solution and ensuring they get paid promptly and in full.

Various paid invoicing programs promise a wealth of features, but most, if not all, of these features are available on free invoicing software, and it's these programs we'll discuss below.

Benefits of Using Free Invoicing Software

Using free invoice software is one of those seemingly small changes that can make a huge difference to your business, offering benefits such as:

Easy to Use

Small business owners can deal with most invoice software features themselves. They just need to set it, dip in on occasion to make changes and additions, and let the software do the rest.

Save Time

Think of all the time you spend creating invoices at the end of the month. It's fiddly and frustrating, especially when you need to make amendments or chase outstanding invoices.

Invoicing software will do most of the work for you, saving a wealth of time in the process.

Improved Billing Accuracy

Humans make mistakes, especially when the work is tedious. You may place a decimal point in the wrong place, enter a customer's details wrong, or make a typo when entering your address or payment details. At best, those mistakes will waste a few minutes of your time; at worst, they could harm client relationships.

By automating the invoice creation process, invoicing software will eliminate these mistakes.

Send Professional Invoices

Free billing software and invoicing software include a myriad of professional invoice templates. Choose the one that suits your business, add your details (including a business logo and name), and in no time at all, you'll have professional invoices to send to all of your customers!

Easy Invoice Tracking

Whether you're sending a single large invoice or recurring invoices, you'll be able to track every one of them. There are no paper invoices, messy spreadsheets, or other manual invoicing solutions—everything is organised neatly and visually for easy invoice tracking.

Automate Payment Reminders

No one likes sending reminder emails for overdue invoices, but it's something that all businesses must do. With invoicing software, however, you just need to change a few settings and let it do the work.

Automatic payment reminders will be sent at predetermined times, such as 3-5 days after the invoice due date. It will keep sending automatic payment reminders until payment is made and can also warn you when a payment is way overdue.

Keep Records

In addition to tracking key invoice data, invoice software will also keep a record of all invoices sent and payments received, serving as your own simple accounting software.

Easy Integration

Free invoice software is easy to integrate into existing accounting solutions. The best programs will adapt to major software suites to make it easier to use and help you maximise its features.

Key Features of Free Invoicing Software

Good free invoice software will typically provide the following features:

  • Invoice Generator: Choose from various invoice templates and create invoices that include all of your business and payment details.
  • Customisation: Create custom fields, change images and formatting, include additional information, and create professional-looking digital invoices.
  • Recurring Billing: Create and send recurring invoices.
  • Invoice Tracking: Track payments, late payments, and overdue invoices.
  • Expense and Time Tracking: Some advanced programs include features for tracking your total time and expenses, allowing you to create detailed invoices and get paid for every expense and every minute worked.

Top Free Invoicing Software Options

Free doesn't mean low-quality. Free invoice software often includes many of the same features that you get with premium versions. In some cases, it's the same software, with the "free" aspect coming from a free trial or a limited version, one that doesn't include the full spectrum of features that you get with paid invoice processing software.

But if you know what you're looking for and stick with the best providers, you can get all the features you need without any serious limitations or future costs.

Getting Started with Free Invoicing Software

  1. Choose Your Software: Consider the features mentioned above to find the most suitable invoice software for your business.
  2. Read the Small Print: Make sure that the software is actually free, and if it's a free trial, check that you'll be getting the features you want and don't need to pay more for them. Can you send unlimited invoices? Can you add custom fields? Does it integrate with payment gateways to accept online payments?
  3. Sign up: Create an account with your chosen provider.
  4. Change Your Branding: Add a business logo and include all of the necessary information, including contact details and payment details.
  5. Generate Invoices: Use invoice templates to generate invoices.
  6. Send Invoices and Track Payments: Start sending those invoices and make sure you're tracking key invoice data.

How to Create and Send an Invoice with Invoicing Software

The easiest way to get started is to enter your payment information and then choose a template. You can also build your own template, but these programs offer such a wide choice of templates that you should be able to find a suitable option.

Include your logo, name, address, and payment details on each invoice. Double and triple-check this information before reproducing it across various invoices.

Include all possible payment options and enter the information that the client needs to submit a payment, such as secure links for debit and credit card payments and bank account info for bank/wire transfers.

Now, it's time to add the customer's data and send the invoices.

FAQs

Is free invoicing software really free?

Yes, most of it is free. You may be charged for additional services and integrations, but there are many great invoicing programs that are completely free.

Does Google Docs have an invoice template?

Yes, Google Docs has invoice templates, and you can also find templates on MS Word and many other programs. Check the Template Gallery for "Invoices" and choose from one of the options before adding your details.

Why can't I just use Google Docs or MS Word?

Although these programs create invoice templates, they don't provide the sort of features offered by a more specialised service, such as automation features, payment tracking, expense tracking, and recurring invoices.

What should an invoice contain?

It must include an invoice number for easy tracking, as well as contact details (for the sender and recipient), a date, details of the products/services rendered, itemised pricing, and payment information. You should also include your logo to make the invoice look more professional.

How often must I send invoice reminders?

Send reminders periodically, beginning a few days before the payment is due, followed by another reminder shortly after the due date. If it's still not paid, send a final reminder about a week after the due date.
