7 Best Invoice Apps For Small Businesses in 2025

Did you know around 39% of your invoices are flawed?

This translated to friction with your clients, delayed or incorrect payments, and revenue loss.

Not ideal, especially if you’re dealing with 3-5 clients.

With an invoice app you can automate this process, save your recurring invoices or bills, and automaticaally send payment reminders.

What is an invoice app?

An invoice app is a tool that helps you create, send, and manage your invoices easily.

These apps are particularly useful for small businesses, freelancers, and entrepreneurs who have several payers. For example, real-estate agents, translators, etc.

For larger business, an invoice app would definitely fall short because you would have to integrate with many other tools. In this case, we recommend using an accounting tool that can handle all of your finances in a more scalable way or invoice accounting software.

Invoice apps simplify the billing process by providing ready-to-use invoice templates that can be customized with your business logo, payment terms, and itemized details such as products, quantities, taxes, and discounts.

These tools also include automation features that will allow you to automatically send recurring invoices, track payments, calculate taxes, and send reminders to clients who have fallen behind in their payment schedule.

For small businesses, an invoice app is important to protect your bookkeeping and cash flow management.

Invoice app vs. invoice generator

Invoice apps and invoice generator both have the same goal: to create your invoices.

However, there are some differences.

An invoice app is designed to take over billing and invoicing management, including some automated features.

Invoice apps manage the full lifecycle of your invoices, including creation, delivery, and payment collection. You can store client data, track upaid invoices, send automated reminders, and integrate payments.

You can even take it further by choosing invoice apps that are integrated in accounting or bookkeeping software, where you can manage your whole finances.

On the other hand, an invoice generator is a much simpler and basic tool.

These are designed for microbusinesses or solopreneurs who have a unique payer.

With invoice generators you manually enter client details, products or services, amounts, and tax rates, then download or email the invoice as a PDF.

They provide speed and convenience, but once the invoice is sent, you typically lose visibility over its status.

When do you need an invoice app?

If you only send one invoice a month, you can easily manage with tools like Google Docs, Excel, or a simple downloadable invoice template, or invoice generator.

However, once your business starts growing and you start to handle multiple clients, projects, or recurring payments an invoice app can save you from a lot of the struggle.

You’ll know it’s time to switch to an invoice app when:

• You spend too much time creating and sending invoices manually
• You have recurring clients or subscription-based billing
• You want to accept online payments or track overdue invoices
• You need better visibility into cash flow and payment history
• You want a more professional appearance for your billing process

An invoice app will help you save time, reduce human error and improve client relationships by making payments smoother and faster.

Features in an invoicing app

There are many invoicing apps you can choose from, including some free options.

However, before choosing your tool, there are some important features you should look out for.

• Customizable invoice templates

When you create your brand, you should make sure that all documents that come from you follow the same pattern, colour scheme and presentation because they will be associated to you and your brand.

Yes, presentation matters. Even in an invoice.

Many apps offer templates that you can customize to add your logo and brand colors. With templates, you will be able to keep your brand with a professional invoice without spending too much time on the design.

Some tools also give you the option to create reusable templates for different clients or services.

• Invoice tracking and status updates

Once an invoice is sent, you need to know what happens next. The problem is that when you send out many invoices at the same time, loosing track of one can be easy.

The best invoice apps provide real-time tracking. This feature shows you when an invoice has been delivered, viewed, and paid.

This visibility helps you stay on top of pending payments without the need for manual follow-ups.

It also gives you data on average payment times, so you can identify slow-paying clients and adjust your processes accordingly.

• Automated payment reminders

Late payments are a common pain-point for small businesses.

When a client misses the payment deadline, they will automatically send a friendly reminder.

Aside from saving you the awkward email, it will help you focus on other tasks instead of having to check daily if there are any unpaid invoices.

• Recurring billing and subscriptions

If you have regular payments, such as retainers or subscriptions, you can automate these bills.

For businesses that charge customers regularly, such as service retainers, memberships, or subscription plans, recurring billing is a must-have feature.

Instead of manually generating invoices each month, the app automatically creates and sends them on a predefined schedule.

This automation saves significant time and ensures your recurring clients are billed accurately and on time.

• Security and data protection

Since invoicing involves sensitive financial and client data, security is non-negotiable.

Choose an app that provides encrypted data storage, two-factor authentication, and regular automatic backups.

A secure invoicing platform protects your business from unauthorized access, fraud, and data loss.

The best invoice apps allow clients to pay directly through the invoice using integrated payment options like credit cards, PayPal, Stripe, or bank transfers.

Bonus: Integration with bookkeeping and accounting tools

The most powerful invoice apps integrate seamlessly with your bookkeeping and accounting systems.

For example, Eleven combines invoicing with AI-driven bookkeeping, automatically recording each invoice, categorizing income, and reconciling transactions.

When do I need an Invoice app?

An invoice app is a tool designed to send invoices, track payments, and send reminders to late payers.

However, it isn’t always the best solution.

An invoice app is a great solution for small businesses, freelancer, and entrepreneurs who work with a limited number of clients or projects.

It will provide an easy way to handle billing, track payments, and keep professional-looking documents without the complexity of full accounting systems.

But if you manage multiple clients, subsidiaries, currencies, or complex financial processes, an invoice app alone will quickly reach its limits.

Accounting firms, family offices, and CPA practices require a more advanced, integrated system that goes beyond invoicing, such as Eleven.

If you’re a freelancer or small business sending a few invoices a month, a simple invoice app will do the job.
