5 Best Invoicing Tools for Freelancers and Small Businesses

Getting paid shouldn’t be the hardest part of running your business. But if you’re still creating invoices manually, chasing down late payments, or toggling between spreadsheets and email to figure out who owes you what, it probably feels that way.

The right invoicing tool can fix most of that. It automates the tedious parts, gives you a clear picture of your cash flow, and helps you look professional to your clients in the process. The hard part is figuring out which tool actually fits the way you work, because no two freelancers or small businesses operate the same way.

Some tools are built around full accounting and will handle everything from invoicing to payroll. Others are focused specifically on sending invoices and getting paid fast. Some are free, some charge a monthly subscription, and some take a small cut of each transaction. The “best” one depends on what you need right now and where your business is headed.

We looked at dozens of invoicing platforms and narrowed the list to these five.

1. FreshBooks

FreshBooks has built a loyal following among freelancers and service-based businesses, and it’s easy to see why. The platform is designed specifically for people who bill for their time, with built-in time tracking that feeds directly into invoices. You track your hours on a project, and when it’s time to bill, FreshBooks pulls those hours in automatically. That alone saves a lot of back-and-forth at the end of each month.

The Lite plan starts at $23/month and supports up to five billable clients with unlimited invoices. The Plus plan ($43/month) bumps that to 50 clients and adds features like proposals, client retainers, and e-signatures. The Premium plan ($70/month) removes the client cap entirely and adds project profitability tracking. FreshBooks regularly runs promotional discounts for new users, so the first few months often come in significantly cheaper.

FreshBooks also includes a client portal where your customers can view invoices, approve quotes, and pay online through credit card, ACH, Apple Pay, Google Pay, or even Buy Now, Pay Later options through Affirm and Afterpay. Automated late payment reminders and scheduled late fees are available on every plan.

What makes FreshBooks stand out:

• Built-in time tracking that converts tracked hours directly into invoices with a couple of clicks
• Proposals, estimates, and client retainers available on Plus and Premium plans
• Clients can pay through Apple Pay, Google Pay, and Buy Now, Pay Later (Affirm/Afterpay) in addition to standard card and ACH payments
• Mobile mileage tracking included on all plans for freelancers who travel for work

2. QuickBooks Online

QuickBooks Online is the most widely used small business accounting software in the U.S., and its invoicing capabilities are part of a much larger ecosystem. If you need more than just invoicing, QuickBooks handles bookkeeping, expense tracking, bank reconciliation, payroll, and tax preparation.

Plans start at $20/month for Solopreneur (designed for one-person businesses and gig workers), $38/month for Simple Start, $75/month for Essentials, $115/month for Plus, and $275/month for Advanced. All plans from Simple Start and up include unlimited invoicing and estimates. Payment processing fees run 2.99% for card payments, 1% for ACH (with a $1 minimum), and 2.5% for in-person transactions. QuickBooks frequently offers 50% off the first three months for new subscribers.

Where QuickBooks really earns its price is in the ecosystem. It integrates with over 800 third-party apps, and most accountants and bookkeepers already know how to work with it. If you plan to hand your books off to a professional at tax time, QuickBooks makes that handoff simple.

What makes QuickBooks stand out:

• Over 800 app integrations, making it one of the most connected accounting platforms available
• Built-in AI assistant (Intuit Assist) that answers questions about your financial data and automates routine accounting tasks
• Inventory tracking and class/location tracking on higher-tier plans for product-based businesses
• Nearly universal accountant compatibility, since most U.S. bookkeepers and CPAs already work with QuickBooks

3. Wave

Wave is one of the few invoicing platforms that offers a genuinely free tier without major limitations. The Starter plan costs nothing and includes unlimited invoicing, unlimited estimates, expense tracking, and basic financial reporting. There’s no trial period and no hidden upgrade wall for core features.

Wave makes its money through payment processing fees. Credit card transactions cost 2.9% plus $0.60, American Express runs 3.4% plus $0.60, and ACH bank payments are 1% (with a $1 minimum). The Pro plan at $16/month (or $170/year) adds automatic bank transaction importing, multi-user access, receipt scanning, and discounted processing fees for the first ten transactions each month.

The trade-off with Wave is support. Free-tier users get a chatbot and email support only, and response times can be slow. Pro plan users get access to live support, but it still won’t match the level of service you’d get from FreshBooks or QuickBooks. If you’re comfortable figuring things out on your own, that’s a non-issue. If you want hand-holding, look elsewhere.

What makes Wave stand out:

• Completely free core invoicing and accounting with no invoice limits or client caps
• Full double-entry accounting included at no cost, which is unusual for a free platform
• Payroll add-on available (starting at $25/month for Pro subscribers plus $6 per employee) with automatic tax filing in all 50 U.S. states
• Owned by H&R Block, adding a layer of stability that smaller free tools can’t match

4. Zoho Invoice

Zoho Invoice is a completely free invoicing tool that’s been available for over 13 years. Zoho made the decision to drop its paid tiers entirely and offer the full product at no cost, positioning it as a commitment to small business owners. The free plan supports up to two users, three projects, and 500 invoices per year.

The feature set punches above its price (which is zero). You get customizable invoice templates, time tracking, expense management, automated payment reminders, and a customer portal where clients can view invoices, approve quotes, and make payments. Zoho Invoice integrates with over 10 payment gateways including Stripe, PayPal, Square, and Authorize.net, so you’re not locked into a single payment processor.

The real advantage of Zoho Invoice is the broader Zoho ecosystem. If you already use Zoho CRM, Zoho Books, or Zoho Analytics, everything connects seamlessly. Your client data, sales pipeline, and financial records can all live under one roof without paying for separate integrations.

What makes Zoho Invoice stand out:

• Integration with Zoho Sign for legally compliant digital signatures on invoices and quotes (ESIGN and eIDAS compliant)
• Customer portal where clients can view all their transactions, approve quotes, and manage payments in one place
• Compatible with 10+ payment gateways, so you can choose the processor with the best rates for your business rather than being locked in
• Part of the broader Zoho ecosystem (CRM, Books, Analytics), allowing connected workflows without third-party integrations

5. Harvest

Harvest is built around time tracking first and invoicing second. That might sound like a limitation, but for freelancers and agencies that bill by the hour, it’s exactly the right approach. You track time across projects and tasks throughout the week, and when it’s time to invoice, Harvest generates invoices from that tracked time in two clicks. There’s no re-entering data or cross-referencing timesheets.

The free plan includes one seat and two projects. The Teams plan starts at $11/seat/month ($9/seat/month with annual billing) and includes unlimited seats, team reporting, and integrations with Stripe, QuickBooks Online, Xero, and Deel. The Enterprise plan starts at $17.50/seat/month ($14/seat/month annually) and adds profitability reporting, timesheet approvals, activity logs, and SAML-based SSO.

Where Harvest really differentiates itself is in reporting. You can see team capacity at a glance, track project budgets in real time, and compare billable versus non-billable hours across your entire team. It also integrates with tools like Asana, Trello, Slack, and Basecamp, so your team can start timers directly from the project management tools they already use.

What makes Harvest stand out:

• Time-to-invoice workflow that generates invoices directly from tracked hours in two clicks
• Team capacity and utilization reporting that shows who’s overworked and who has bandwidth
• 50+ integrations with project management tools (Asana, Trello, Basecamp, Slack) so your team can track time without leaving their workflow
• Project budget tracking with real-time alerts when budgets are reached

How to Choose the Right Invoicing Tool

The best invoicing tool is the one that matches how you actually work. Here are a few questions worth asking before you commit.

How do you bill your clients?

If you charge by the hour, you need strong time tracking. FreshBooks and Harvest both excel here, but Harvest goes deeper on reporting. If you charge flat rates or project fees, most tools on this list will work fine.

Do you need full accounting, or just invoicing?

QuickBooks and Wave include full accounting features like bank reconciliation, financial reporting, and tax preparation. FreshBooks sits in the middle with solid accounting for small businesses. Zoho Invoice and Invoice Ninja focus primarily on invoicing and leave the accounting to other tools.

What’s your budget?

If it’s zero, Wave and Zoho Invoice both deliver strong free options. If you can spend $10-25/month, FreshBooks Lite offers excellent value. QuickBooks starts making sense when you need more advanced features or plan to work with an accountant.

How many clients do you work with?

Some tools cap the number of billable clients on lower-tier plans. FreshBooks Lite limits you to five. Zoho Invoice caps you at 500 invoices per year. If you’re sending dozens of invoices every month, make sure the plan you choose can keep up.

Do you work internationally?

If you bill clients in multiple countries or currencies, Stripe Invoicing (which we didn’t include in this list but is worth mentioning) supports 135+ currencies and 25+ languages. Zoho Invoice also handles multi-currency billing well.

Whatever you choose, the most important step is getting off manual invoicing. Even the simplest tool on this list will save you time, get you paid faster, and give you a clearer picture of where your money is coming from.
