Invoicing software should do two things: make it easy to send professional invoices and help you get paid quickly. Most platforms succeed at the first while complicating the second with unnecessary features freelancers don’t need.

We tested seven invoicing tools for four months, sending real invoices and tracking payment times, to see which platforms actually improve cash flow.

Wave: Free and Functional

Wave offers completely free invoicing with no limits. The catch is they make money from optional paid services (payments, payroll), but the core invoicing genuinely costs nothing.

Creating invoices is straightforward. Choose a template, add line items, set payment terms, and send. Customization options include logo, colors, and terms.

Payment reminders automate follow-ups. Wave sends automatic reminders for overdue invoices, saving you from awkward emails.

The mobile app lets you create and send invoices from phones. Useful when you finish a job and want to invoice immediately.

Accepting payments requires Wave Payments (2.9% + 30¢ for credit cards). This is competitive with alternatives. Bank transfers are 1% with $1 minimum.

Expense tracking and accounting features are included free. For freelancers needing basic bookkeeping, Wave provides an all-in-one solution at no cost.

The main limitation is that it looks free. Templates are professional but not premium. For freelancers billing smaller amounts, this is fine. For consultants billing thousands, more polished options exist.

FreshBooks: Polished Professional

FreshBooks targets professional service businesses with invoicing, time tracking, and project management integrated.

Invoice templates are clean and customizable. The platform looks professional, which matters when billing corporate clients.

Time tracking ties directly to invoicing. Track hours by project, then convert to invoices automatically. For consultants and agencies billing hourly, this saves significant time.

Client portal gives clients access to invoices, estimates, and project updates. This reduces email back-and-forth.

Accepting payments requires FreshBooks Payments (2.9% + 30¢ for cards). The integration is smooth with payment status updating automatically.

Pricing starts at $19/month for Lite (5 clients), $33/month for Plus (50 clients), or $60/month for Premium (unlimited clients). For freelancers with few clients, entry pricing is steep.

For established consultants and agencies billing professional rates, FreshBooks provides a premium experience that justifies the cost. For freelancers just starting, it’s expensive.

Invoice Ninja: Open Source Option

Invoice Ninja offers free self-hosted invoicing or cloud hosting starting at $10/month. The open-source model provides flexibility and control.

Features are comprehensive: invoicing, quotes, payments, time tracking, expenses, vendor management. More functionality than Wave with more customization than FreshBooks.

Templates are customizable with CSS for users who can code. Stock templates are functional but less polished than FreshBooks.

Payment integration supports multiple processors (Stripe, PayPal, Square). You connect your own accounts, avoiding Invoice Ninja taking a cut.

The interface feels more utilitarian than polished. It works, but design isn’t the priority.

For technical freelancers who want control and don’t mind less polish, Invoice Ninja provides excellent value. For non-technical users wanting simplicity, Wave or FreshBooks work better.

Bonsai: All-in-One for Freelancers

Bonsai combines invoicing with contracts, proposals, time tracking, and task management. The integrated approach helps freelancers manage complete client lifecycles.

Contract templates cover common freelance scenarios. Customize templates, send for e-signature, and track status. For freelancers tired of legal uncertainty, pre-built contracts provide confidence.

Proposals with pricing options let clients choose packages. Approved proposals convert to contracts and projects automatically.

Invoicing works smoothly with multiple payment options. Automated reminders and late fees encourage timely payment.

Time tracking and task management help organize work. These features are basic compared to dedicated project management tools but adequate for solo freelancers.

Pricing is $17/month for Starter (basic features) or $32/month for Professional (everything). The annual plan discounts to $21/month for Professional.

For freelancers wanting one tool for most business needs, Bonsai provides good value. For freelancers happy using multiple specialized tools, it’s not necessary.

PayPal Invoicing: Surprisingly Decent

PayPal’s invoicing is free and works better than expected. For freelancers already using PayPal, it’s worth considering.

Creating invoices is simple. Add items, choose from recent customers, send. Clients can pay directly with PayPal or credit card.

Payment processing fees are standard PayPal rates (2.9% + 30¢ for domestic transactions). Since many freelancers already pay these fees, there’s no additional cost.

The interface is basic. Limited customization and basic templates. It works but doesn’t look premium.

Integration with PayPal account means payments appear immediately. No waiting for transfers from invoice platform to payment processor to bank.

For freelancers with simple invoicing needs who already use PayPal, the built-in invoicing saves paying for another tool. For professional presentations, dedicated tools look better.

QuickBooks Online: Accounting with Invoicing

QuickBooks is accounting software that includes invoicing. For freelancers who need both, the integration is useful. For those who just need invoicing, it’s overkill.

Invoice features are comprehensive with professional templates, automatic reminders, and payment processing.

The accounting features track income and expenses, categorize transactions, and generate reports for taxes. For freelancers who don’t want separate accounting software, QuickBooks handles both.

Pricing starts at $15/month for Simple Start (income and expense tracking, invoicing). Essentials at $36/month adds bill management.

For freelancers needing accounting and invoicing, QuickBooks combines both at reasonable cost. For invoicing only, simpler tools cost less.

Zoho Invoice: Budget-Friendly

Zoho Invoice is free for up to 1,000 invoices annually. Paid plans start at $10/month for unlimited invoicing and features.

Features include invoices, estimates, recurring billing, time tracking, and expense management. Comparable to FreshBooks at lower price.

Integration with other Zoho products (Books, CRM) works well. For Zoho ecosystem users, Invoice fits naturally.

Templates and interface feel dated compared to FreshBooks but are functional. Everything works; it just doesn’t feel modern.

For budget-conscious freelancers needing more than Wave but not wanting to pay FreshBooks prices, Zoho Invoice provides middle ground.

What Actually Affects Getting Paid

After tracking payment times across platforms, certain factors matter more than others:

Payment options directly affect how fast you get paid. Clients pay faster when they can use their preferred method. Platforms supporting cards, bank transfers, and PayPal get paid faster than check-only invoices.

Automatic reminders reduce awkward follow-ups. Invoices with automated overdue reminders get paid faster than those requiring manual follow-up emails.

Professional presentation matters for higher invoices. A $5,000 consulting invoice on a polished FreshBooks template gets paid faster than the same on a basic template. For $200 invoices, this matters less.

Mobile invoicing enables invoicing immediately after completing work. The faster you invoice, the faster you get paid. Mobile apps from Wave, FreshBooks, and Bonsai excel here.

The Payment Processing Decision

Most invoicing platforms offer payment processing at similar rates (2.9% + 30¢ for cards). The question is whether to accept cards at all.

Accepting cards gets you paid faster and more reliably. The 3% fee is the cost of improving cash flow. For most freelancers, this tradeoff is worth it.

Bank transfers through platforms like Wave (1% fee) save on fees but add payment friction for clients. Test what your clients prefer.

Our Recommendations

Best free option: Wave. Genuinely free with no limits. Professional enough for most freelance work. Payment processing fees are competitive.

Best for professional services: FreshBooks. Polished presentation and time tracking integration justify the cost for consultants billing professional rates.

Best all-in-one for freelancers: Bonsai. Contracts, proposals, invoicing, and basic project management in one platform. Good value at $21/month annually.

Best for technical users: Invoice Ninja. Open source provides control and customization. Self-hosting is free; cloud hosting is affordable.

Best if you’re already using PayPal: PayPal Invoicing. It’s free and integrates with your existing account.

Best if you need accounting too: QuickBooks Online. Invoice and track finances in one tool. Useful for tax time.

Beyond the Software

Invoicing software won’t fix late-paying clients. Clear payment terms, deposits for larger projects, and penalties for late payment matter more than which tool you use.

Net 30 payment terms are negotiable. Net 15 or Net 7 improves cash flow. Immediate payment for small projects eliminates waiting entirely.

Following up consistently matters more than software features. Even the best platform won’t collect payment if you don’t follow up on overdue invoices.

For very small projects, consider requiring upfront payment. No invoice necessary—they pay before you start. This eliminates all payment delays and reduces administrative work.

The right invoicing software depends on your volume, client types, and whether you need additional features like time tracking or accounting. For simple needs, Wave provides everything necessary for free. For professional presentation, FreshBooks justifies its cost. For all-in-one business management, Bonsai provides good value.

Test free tiers or trials before committing. Create actual invoices, not demo data. See if the workflow matches how you work and whether the presentation matches your brand.

The best invoicing software is the one you’ll actually use consistently. Simpler tools used immediately after completing work beat sophisticated tools that sit unused because they’re complex. Get invoices sent quickly and follow up consistently—that affects payment speed more than which platform you choose.
