What’s the best invoice app for small businesses? Without a dedicated accounting team, the job of invoicing falls to small business owners themselves. But using software to create an easy invoice can make your life as a small business owner far simpler.

What’s the best invoicing app?

Here are seven well-known apps that could make your life as a small business owner easier.


QuickBooks by Intuit is one of the most well-known invoicing and accounting apps for small businesses. We featured it in our list of the best accounting software for small businesses.

QuickBooks is a general accounting app that can streamline your business’s finances. You can even connect your online bank account to the software, reducing any manual data entry errors.

It’s also great for invoicing. You can see and update your invoices from a single dashboard, automate sending your invoices, and the software can proactively show you the impact of paying bills on your cashflow.

QuickBooks’ Self-Assessment Ready plan for freelancers and independent contractors costs £8.00 a month. They also have a choice of plans for small businesses and VAT-registered companies in their Making Tax Digital for VAT Ready category, starting at £12.00 a month.

Try out the invoicing app plan that suits your business best. Both Quickbooks for Self-Employed and Quickbooks for Small Businesses are available on iPhone and Android.


FreshBooks more specifically tracks invoicing for small businesses and freelancers, with time and expense tracking features too. You can customise your invoices (such as by adding your logo) and send them as an email or send a paper copy.

FreshBooks say they have award-winning customer service and the team are very active on social media. Their help centre features how-tos and everything customers need to get started.

The £19 per month ‘Plus’ plan lets you invoice up to 50 clients. Give it a go. You can also access the FreshBooks invoice app for Android or iPhone.


Wave's invoice software comes on probably the best pricing plan possible – free. It only charges you for payments, payroll and premium support, meaning it’s useful for small businesses, as you’ll only pay for what you need.

Wave has an easy-to-use interface and a great set of invoicing features, including customisations, column editing, and the ability to create recurring invoices and set reminders. Check it out.

If you want to use Wave on the go, you can get the app from the App Store (iPhone) or Google Play (Android).

Zoho Invoice

Zoho has many different cloud applications for small businesses, but its invoicing software, Zoho Invoice, is ideal for small businesses.

Even though Zoho Invoice has extensive capabilities, it’s very quick to create an easy invoice and has a user-friendly interface. You can create invoices, estimates and set up retainer invoicing.

Its pricing plan suits growing businesses – Zoho Invoice is free for businesses with under five customers. The ‘Basic’ plan is £6 a month and lets you invoice up to 50 customers. Find out more.

Zoho Books is the full-fledged accounting software that we included as one of the best pieces of accounting software for small businesses.

The Zoho Invoice app is available in iOS, Android, and Microsoft versions, so you don't have to be sitting down at your laptop to use it.


Invoicely used to be known as Invoiceable. Whereas some other free invoice builder apps put limitations on the number of invoices you can send, Invoicely lets you send unlimited invoices to unlimited customers, even on the free plan. This makes it useful for businesses just starting out.

It’s cloud-hosted and easy to use and if you want more features as your business grows, its pricing plan is very affordable. The ‘Basic’ plan is $9.99 a month and gives you the ability to track time and expenses, set up recurring statements and provide quotes. Visit their website.


InvoiceBerry is designed specifically for small and micro businesses, unlike many of the invoice builder apps we’ve already highlighted.

InvoiceBerry has simplicity in mind. They claim that through the software, you can create and deliver invoices to customers in under a minute. The software will send reminders to late payers and even send a thank you note when a payment has been received.

For €12 a month, the 'Solo' plan allows you 15 invoice templates, 35 clients, and two users, whereas the 'Pro' plan offers unlimited clients and users, and 15 invoice templates, for €24 a month.

Try out InvoiceBerry.


KashFlow is a UK-based business, which means many of its features are built with the UK market in mind. For instance, it can link directly to HMRC – the software produces VAT Returns and EC Sales lists and files them to HMRC.

KashFlow is an accounting app, and its invoicing features include turning quotes to invoices in one click and automatic alerts that inform you of any late payers.

The pricing plan is very reasonable: KashFlow says its £8 a month ‘Starter’ option is perfect for sole traders, contractors and small businesses. Try it out.

KashFlow Go, the mobile version of this invoicing app, is available on both the App Store (iPhone) and Google Play (Android).

Be sure to research all your options before choosing an app for your business and get professional advice, if you need to.
