Many or all of the products featured here are from our partners who compensate us. This may influence which products we write about and where and how the product appears on a page. However, this does not influence our evaluations. Our opinions are our own. Here is a list of our partners and here's how we make money.

Invoicing software allows small-business owners to keep track of what goods and services they’re providing to customers and how much those customers owe. The best versions of this software let businesses manage that process end to end — from creating estimates for new projects to tracking hours worked to collecting payments.

All of our best invoicing software picks offer these features and more to help business owners stay organized.

Zoho Invoice: Best overall invoicing software

Price: Free for businesses with up to five customers and one user, $9 per month for up to 50 customers and one user, $19 per month for up to 500 customers and three users, and $29 per month for unlimited customers and 10 users.


  • Users can create estimates, log expenses and track task hours and staff hours. All three types of information can be converted into or added to invoices.

  • Clients can access a password-protected portal where they can see their estimates, payment history and receipts.

  • The free version is robust. The only features it lacks compared with other versions are Twilio integration and the creation of a custom domain.


  • Zoho Invoice integrates with other software programs via Zapier, but offers native integrations with Zoho Books, Zoho CRM and other Zoho apps. If your business uses accounting and CRM software, it may be easier to use the whole Zoho suite.

Why we like it: Zoho Invoice is comprehensive yet feels easy to use. You can keep track of hours or tasks on a variety of projects in an app or browser. When work is complete, you can send highly customizable invoices to customers, along with automated email reminders when payments are overdue. And Zoho Invoice’s pricing structure means that small businesses can take advantage of almost all of its features, even if they’re using the free or lowest-cost versions.

Invoice Ninja: Best free invoicing software

Price: Free. For additional features, users can upgrade to the Pro plan at $10 per month or the Enterprise plan, which ranges from $14 to $44 per month depending on the number of users.


  • Unlimited quotes and invoices to 100 clients.

  • Users can create quotes and track time, and both can be converted into invoices.

  • Integration with more than 40 payment gateways so sellers can accept credit cards and payment in many currencies, including cryptocurrency.


  • No seamless integration with bookkeeping or accounting software. Invoice Ninja can integrate with other apps via Zapier, including QuickBooks and Xero, but users need to set up those integrations themselves. (If you’re focused on a completely free solution, note that this could result in an additional cost, since Zapier’s free plan only allows a small number of automations.)

Why we like it: Among free invoice software options, Invoice Ninja allows you to serve a much larger number of clients than most of its competitors. Invoice Ninja offers all of the key features of an invoicing software, including time tracking integration, the ability to ask customers to pay a deposit upfront and the opportunity to add taxes and discounts to invoices. The paid versions come with additional useful features like bulk invoicing, but the free version is so robust that you may never need to upgrade.

Hiveage: Best invoicing software for freelancers

Price: Free plan includes unlimited invoices for up to five clients, $16 per month for up to 50 clients, $25 per month for up to 250 clients and five team members and $42 per month for the enterprise version, which supports up to 1,000 clients and 10 team members.


  • The free version allows business owners to serve up to five clients, which could be enough for many freelancers and solopreneurs.

  • Simple, straightforward software that’s easy to use.

  • Supports a dozen payment gateways and allows users to accept partial payments.


  • If your business grows and you need additional features that aren’t directly related to invoicing, such as processing payroll or bookkeeping, you’ll need another software solution.

Why we like it: If you’re feeling overwhelmed by all of the features other software programs offer and all you need to do for your freelance business is send invoices and receive payments, Hiveage stands out for its simplicity. Creating one-time and recurring invoices is straightforward, the dashboard is easy to navigate, and it offers time, expense and mileage tracking even in the free version. Hiveage can also integrate with accounting, CRM and project management software via Zapier.

Harvest: Best software for hourly invoicing

Price: Free for one user with two active projects; $12 per month for unlimited users and unlimited projects.


  • Advanced time-tracking features, including integrations with Google Calendar, Slack, Asana, Trello and other project management tools.

  • Expense-tracking features, including the ability to upload receipts and track mileage.

  • Project managers can add other team members to projects so that they can track their own time and expenses within Harvest.


  • Invoices aren't particularly customizable — free users can’t add a logo, and Harvest offers only one template.

  • Limited pricing options mean all but the smallest businesses will have to pay $12 per month.

Why we like it: Harvest allows members of a project team to track their hours and expenses in detail, often within whatever apps project managers are using. Managers can set the budget for a project and track expenses and hours to make sure teams are working efficiently. When it comes to invoicing, Harvest’s estimate, invoice and payment collection tools are easy to navigate, and it offers helpful features like automated email reminders to customers.

FreshBooks: Best all-in-one invoicing and accounting software

Price: $15 per month for up to five billable clients, $25 for up to 50 billable clients and additional accounting features, $50 per month for unlimited clients and additional customization features. Additional team members cost $10 per person per month. Custom pricing available beyond these options.


  • Native integrations with dozens of other software programs, including payroll, inventory and e-commerce software.

  • Well-designed versions of standard features, including automated payment reminders, the ability to add discounts and taxes, and updates when an invoice has been viewed or paid.

  • Bookkeeping and accounting features.


  • There is no free option. And while FreshBooks’ project management and collaboration tools are helpful, adding team members comes with additional costs.

Why we like it: FreshBooks offers invoicing features that are competitive with others in this space, albeit for a price. On top of that, its accounting services — including double-entry accounting reports and the ability to add your accountant as a team member — set FreshBooks apart (in fact, it’s one of NerdWallet’s picks for the best accounting software for small businesses). If you’re a solopreneur or leader of a small business looking to ease communication with your clients and accountant, this all-in-one solution could help.

How to choose your invoicing software

Ask yourself these questions to help determine what invoicing software is right for you.

Is it scalable? 

Make sure to think about the future, not just the present. Since most invoicing software programs determine pricing based on how many clients you have, business growth could mean rising costs. Look for software that will support the business you’re planning to be running in a year without requiring you to leap up to a much higher pricing tier.

Is it easy to use for you and your clients? 

Most invoicing software makers offer free trials to potential customers. Take advantage of these to make sure you understand how to use the features you need. Choose payment gateways that accommodate your clients, especially if you have clients abroad and need to support multiple currencies. Take time to test the software from the client's end, too.

Does it integrate with the software you already use? 

If you rely on other software programs already, look for an invoicing option that integrates with them. Many of the options on this list integrate with other software via Zapier, an intermediary software that users have to set up themselves. Make sure to test those integrations before you commit to one program.

The right invoicing software might allow you to consolidate some of your tasks into one place. If you use a time-tracking app, for instance, consider switching to an invoicing software with native, or built-in, integrations that can meet those needs too.

How much does it cost? 

The “freemium” model of most invoicing software programs can make it hard to project costs. Growth in your client base or changes to your staffing levels might bounce you into a different price tier. Plus, some important features might actually be add-ons with additional fees.
