invoicing software for freelancers
Freelancers lose real money to invoicing problems. Late payments, forgotten follow-ups, and those awkward “just checking in on my invoice” emails add up to thousands of dollars in delayed cash flow every year. Industry data shows that roughly a third of freelance invoices get paid late.
The good news is that you don’t need expensive software to fix this. Most of the best invoicing tools for freelancers are either completely free or cost less than a single lunch out. The right one depends on how many clients you handle, whether you bill hourly or per project, and how much accounting you want baked in.
Here are seven tools that real freelancers actually use — sorted from free options first, because that’s where most solopreneurs should start.
TL;DR — If you just need to send clean invoices and get paid, start with Zoho Invoice (free, up to 500 invoices per year) or Wave (free, unlimited invoices plus basic accounting). If you want the most polished experience with automated reminders and late fees, FreshBooks is worth the subscription. Already have a PayPal or Square account? Their built-in invoicing is free and might be all you need.
Quick Comparison
| Tool | Price | Free Invoices | Best For |
|---|---|---|---|
| Zoho Invoice | Free | 500/year | All-around free invoicing |
| Wave | Free | Unlimited | Invoicing + accounting together |
| Invoice Ninja | Free | Unlimited | Tech-savvy freelancers |
| PayPal Invoicing | Free | Unlimited | International clients |
| Square Invoices | Free | Unlimited | Service providers with in-person payments |
| FreshBooks | $23/mo | N/A (paid) | Professional automation |
| QuickBooks Solopreneur | $15/mo | N/A (paid) | Tax prep with TurboTax |
A note on “free”: every tool that accepts online card payments charges processing fees, typically around 2.9% + $0.30 per transaction. That’s the payment gateway cost, not a software fee. You’d pay that on Stripe or any other processor, too. The subscription cost is what we’re comparing.
The 7 Best Invoicing Tools for Freelancers
1. Zoho Invoice
Free
Best for: freelancers who want full-featured invoicing at zero cost
Zoho Invoice is the free invoicing tool that’s hardest to outgrow. The free plan includes customizable invoice templates, automated payment reminders, recurring invoices, expense tracking, time tracking, and a client portal where your customers can view and pay invoices directly. It supports multi-currency, which matters if you work with international clients.
Payment integrations include Stripe, PayPal, and Square, so clients can pay however they prefer. You get up to 500 invoices per year — roughly 40 per month — which is more than enough for most solo freelancers. The mobile app is excellent, rated 4.8 out of 5, with nearly the full feature set available on your phone.
The main limit is scale: once you pass 500 invoices per year or need more than 2 users, you’ll need to upgrade to Zoho Books (starting around $10/month). But if you’re a solo operator sending invoices weekly, you may never hit that ceiling.
Strengths
Genuinely free with no trial period. Time tracking built in. Client portal included. Multi-currency support.
Watch Out For
500 invoice/year cap. Limited to 2 users. No built-in proposal creation. Support can be slow on the free tier.
2. Wave
Free (Starter plan)
Best for: freelancers who want invoicing and accounting in one free tool
Wave’s Starter plan gives you unlimited invoices, unlimited estimates, expense tracking, and basic accounting — all free. Your invoices automatically post to your books, which means no double-entry at tax time. For a freelancer who hates spreadsheets but needs to track profit and loss, that’s a meaningful perk.
Wave has been around since 2010 and is now owned by H&R Block. The free tier has gotten slightly more restrictive over the years — features like automatic bank transaction imports and receipt scanning now require the Pro plan ($19/month) — but the core invoicing remains free and unlimited.
One thing to be aware of: Wave’s payment processing has had some reliability issues. Some users have reported fund freezes after accepting payments through Wave Payments. If you want to use Wave for invoicing but avoid that risk, you can send invoices through Wave and accept payment through your own Stripe or bank transfer setup instead.
Strengths
Unlimited invoices. Free accounting built in. Clean interface for beginners. No client cap on free plan.
Watch Out For
No time tracking. No proposals or contracts. Higher per-transaction fees (2.9% + $0.60). Some payment processing reliability concerns.
3. Invoice Ninja
Free (self-hosted) / $14/mo (hosted Pro)
Best for: tech-savvy freelancers who want full control over their data
Invoice Ninja is the open-source option. If you’re comfortable setting up a server (or already have hosting), you can run the full platform for free with unlimited clients, invoices, quotes, and support for over 40 payment gateways. If you’d rather not manage infrastructure, the hosted free plan covers up to 20 clients, and the Pro plan at $14/month removes the cap and the branding.
The feature set is deeper than most free tools: time tracking, expense management, recurring invoices, proposals, and a client portal. It’s actively developed — the latest release dropped in May 2026. For freelancers in fields with data sensitivity requirements (legal, healthcare, finance consulting), the self-hosted option means your client data stays on your own server.
The trade-off is setup complexity. If you just want to send an invoice in the next five minutes, start with Zoho or Wave. If you want a long-term solution you fully own, Invoice Ninja is worth the learning curve.
Strengths
Open source. Self-hosting option. Unlimited everything on free self-hosted. 40+ payment gateways. Active development.
Watch Out For
Self-hosting requires technical know-how. Hosted free plan capped at 20 clients. Interface has a steeper learning curve.
4. PayPal Invoicing
Free (pay-per-transaction only)
Best for: freelancers with international clients who already use PayPal
If your clients already pay you through PayPal, you might not need another tool at all. PayPal’s built-in invoicing lets you create and send unlimited invoices at no subscription cost. Clients can pay via PayPal balance, Venmo, credit or debit cards, Apple Pay, or even Buy Now/Pay Later installments — making it one of the most flexible payment options for the person on the receiving end.
The invoicing itself is basic: line items, payment terms, your logo, send. No time tracking, no proposals, no accounting integration beyond PayPal’s own activity log. Processing fees run about 3.49% + $0.49 per transaction in the US, which is higher than most competitors.
The risk worth knowing about: PayPal occasionally freezes accounts during disputes, and their buyer-protection policies tend to favor the buyer. For ongoing retainer clients you trust, it works great. For one-off projects with new clients, consider having a backup payment method.
Strengths
No subscription fee. Clients can pay via PayPal, Venmo, Apple Pay, and BNPL. Great for international payments. Instant setup if you have a PayPal account.
Watch Out For
Higher processing fees than competitors. No time tracking or accounting. Account freeze risk during disputes. Very basic invoicing features.
5. Square Invoices
Free / Plus at $29/mo
Best for: service providers who also take in-person payments
Square Invoices is genuinely free with no monthly fee — you pay only the standard processing rate (2.9% + $0.30 for online payments) when a client actually pays. The free plan includes unlimited invoices, automated payment reminders, custom branding, recurring invoices, and a solid mobile app.
Where Square really shines is if you already use Square for in-person payments (think consultants, tutors, personal trainers, photographers). Everything lives in one dashboard, so you can see in-person and invoiced income together. The Plus plan ($29/month) adds milestone billing, project-based invoicing, and team management for when you start growing.
The gaps: no multi-currency support on the free plan, no time tracking, and no project management. If you only do remote work and never see clients face-to-face, Square’s biggest advantage doesn’t apply to you.
Strengths
No subscription fee. Clean mobile experience. Unified dashboard with in-person payments. Milestone invoicing on Plus plan.
Watch Out For
No multi-currency on free plan. No time tracking. No project management. Limited value if you don’t do in-person work.
6. FreshBooks
From $23/mo (Lite)
Best for: established freelancers who want polished invoicing with automation
FreshBooks is the premium pick, and it earns that spot with the most polished invoicing experience in this category. The invoice builder is drag-and-drop with your branding, customizable colors, and templates that look professional without any design effort. Set up automatic late payment reminders, schedule late fees, and the software follows up on your behalf so you never have to send the awkward “just checking in” email.
Beyond invoicing, FreshBooks includes time tracking (log hours per client, add them to invoices), expense tracking with receipt capture, profit-and-loss reports, and online payments via credit card, ACH, or PayPal. The Plus and Premium plans add proposals, contracts, and more advanced reporting.
The trade-off is price. FreshBooks has raised prices several times recently — the Lite plan went from $17 to $23/month, and it caps you at 5 billable clients. The Plus plan ($43/month) removes the client cap. For freelancers who invoice regularly, track time, and want everything in one polished platform, the cost is justified by the time saved. For someone sending three invoices a month, a free tool will do.
Strengths
Best-in-class invoice design. Automated reminders and late fees. Built-in time tracking. Excellent mobile app. Strong accounting features.
Watch Out For
Lite plan limited to 5 clients. Price has increased significantly. No free tier. Not ideal for low-volume invoicing.
7. QuickBooks Solopreneur
From $15/mo
Best for: freelancers who want invoicing that feeds directly into tax prep
If your accountant already uses QuickBooks, or if you file taxes through TurboTax, QuickBooks Solopreneur is the path of least resistance. Invoices accept payment via credit card, ACH, PayPal, Venmo, and Apple Pay. The accounting and tax categorization is where QuickBooks earns its reputation — it organizes your income and expenses in the exact categories you need for Schedule C.
The invoicing itself is functional but not flashy. You won’t get the polish of FreshBooks or the depth of a dedicated invoicing tool. There’s no built-in time tracking, no proposals, no contracts, and no client portal. Think of QuickBooks as an accounting tool that happens to do invoicing, rather than the other way around.
For freelancers who dread tax season more than they dread invoicing, QuickBooks solves the bigger problem.
Strengths
Direct TurboTax integration. Strong tax categorization. Multiple payment options for clients. Industry-standard accounting.
Watch Out For
No time tracking. No proposals or contracts. No client portal. Invoicing is basic compared to dedicated tools.
How to Choose the Right One
The “best” invoicing software depends entirely on where you are in your freelance business. Here’s a quick decision framework:
If you’re just starting out and send fewer than 10 invoices a month, go with Zoho Invoice or Wave. Both are free, both create professional-looking invoices, and both accept online payments. Zoho has better time tracking; Wave has better accounting. Pick whichever gap matters more to you.
If you already use PayPal or Square for payments, try their built-in invoicing first. You might not need another tool at all. The invoicing features are basic, but if basic is all you need, adding another subscription is just overhead.
If you bill hourly and manage multiple clients, you need time tracking that connects to your invoices. FreshBooks does this best among the paid options. Invoice Ninja does it for free if you’re willing to self-host.
If late payments are your biggest problem, automated reminders and late fees are the highest-leverage features. FreshBooks handles this automatically. Zoho Invoice and Wave have reminders but not configurable late fees.
If tax prep is the real headache, QuickBooks Solopreneur feeds your invoice data directly into the categories you need for filing. It solves the downstream problem that invoicing alone doesn’t touch.
Know Your Numbers Before You Invoice
Picking the right invoicing tool is step one. But the bigger question is whether you’re charging enough to begin with. If your freelance rate doesn’t account for taxes, time off, health insurance, and non-billable hours, even perfect invoicing won’t save you from underearning.
Before you send your next invoice, run your numbers through our Freelance Rate Calculator. It factors in your target income, expenses, and billable hours to tell you what you actually need to charge per hour or per project. Pair that with good invoicing software, and you’ve solved both sides of the getting-paid equation.
If you’re also tracking income from multiple freelance gigs, our Side Hustle Income Calculator helps you see how different revenue streams add up after taxes and expenses. And if debt is eating into your freelance income, the Debt Payoff Calculator can help you build a payoff plan that accounts for your variable income.
