Invoicing is where freelance work turns into freelance income. Pick the wrong app and you waste hours on data entry, chase clients with broken payment links, or end up paying $30 a month for features you never touch. Pick the right one and invoicing becomes a two-minute task you barely think about.
This roundup looks at the best free invoicing apps for freelancers in 2026. Each option below has a genuinely free tier — not a 14-day trial that converts into a subscription. We tested how each handles the actual freelance workflow: tracking billable hours, generating a clean PDF invoice, sending it, and recording payment. Pricing is current as of May 2026.
1. Stintly — Best Free Option for Simple, Offline Invoicing
Pricing: Free. No account, no subscription, no premium tier.
Stintly is built for the freelancer who wants to track time, log expenses, and send an invoice without giving up an email address or sitting through onboarding videos. Open the app, start a timer on a client project, stop it when you are done, and the hours roll into an invoice you can export as a PDF.
Why it wins for solo freelancers: Stintly runs fully offline on iPhone and iPad. No cloud sync means no monthly fee, no account hijacks, and no waiting for a connection in a coffee shop with bad Wi-Fi. Data lives on your device, which is also the privacy answer most accountants quietly prefer.
Pros:
- Genuinely free — no upsells, no locked features
- Time tracking, expense logging, and invoicing in one app
- Works offline; nothing leaves the device unless you export it
- No sign-up — tap install and start working
- Clean PDF invoices with your branding, hourly breakdowns, and tax lines
Cons:
- iOS only — no Android or web version
- No built-in payment processor; you collect via Stripe link, Zelle, or bank transfer separately
- Single-user only — not meant for agencies with multiple contractors
Best for: Solo freelancers, consultants, designers, writers, and developers who bill hourly or by project and want a no-friction tool that respects their data.
Stintly is free to download. Download Stintly for Free — no account needed, works offline.
2. Wave — Best for Free Unlimited Invoicing with Accounting
Pricing: Free for invoicing and accounting. Payment processing 2.9% + $0.60 per card transaction. Optional Pro plan $16/month adds receipt scanning and automated reminders.
Wave has been the go-to free option for over a decade, and the core invoicing and accounting modules remain free in 2026. You get unlimited invoices, double-entry bookkeeping, and basic financial reports without paying a cent.
Pros:
- Truly free invoicing with no invoice cap
- Real double-entry accounting included
- Accepts credit cards and ACH out of the box
- Web and mobile apps
Cons:
- Customer support is paid-only since the H&R Block acquisition
- Receipt scanning moved to the paid tier
- Card fees are higher than Stripe direct (2.9% + $0.60 vs 2.9% + $0.30)
- Requires an account and cloud sync
Best for: Freelancers who want bookkeeping bundled with invoicing and do not mind cloud-based tools.
3. QuickBooks Solopreneur — Best for Tax-Heavy Freelancers
Pricing: No free tier in 2026. Solopreneur plan starts at $20/month (frequently discounted to $10/month for the first three months). The old Self-Employed product was renamed and absorbed into Solopreneur in 2024.
Not free, but worth including because freelancers keep asking. QuickBooks Solopreneur shines if you are 1099 income heavy and want Schedule C estimated quarterly taxes calculated automatically. Mileage tracking and bank feed categorization are the real value here, not the invoicing itself.
Pros:
- Automatic mileage tracking via GPS
- Estimated quarterly tax calculations
- Easy export to TurboTax
- Bank and credit card sync
Cons:
- Not free — no permanent free tier exists
- Invoicing features are weaker than FreshBooks or Wave
- Subscription rises sharply after the intro discount
- Cancellation flow is notoriously sticky
Best for: US-based freelancers with significant self-employment tax obligations who value tax automation over invoicing polish. If you want the QuickBooks tax features without the subscription, see our offline free alternatives to QuickBooks roundup.
4. FreshBooks — Best Free Trial for Client-Heavy Workflows
Pricing: 30-day free trial, then $21/month (Lite) for up to 5 billable clients. No permanent free tier.
FreshBooks is the most polished invoicing experience on this list. Recurring invoices, late fees, automatic payment reminders, and proposal-to-invoice conversion all work smoothly. The catch: it stops being free after 30 days, so it only earns a spot here for freelancers who want a strong free trial while they migrate from spreadsheets.
Pros:
- Best-in-class invoice design and customization
- Proposals, retainers, and project management included
- Strong mobile apps on iOS and Android
- Excellent customer support — phone, chat, and email
Cons:
- Not free — 30-day trial only
- Lite plan caps you at 5 clients, which most freelancers blow through quickly
- Card processing 2.9% + $0.30 plus FreshBooks markup on some plans
Best for: Freelancers ready to pay for a premium tool with retainers and proposals baked in. For a head-to-head, see Stintly vs FreshBooks 2026.
5. Zoho Invoice — Best Free Web-Based Invoicing
Pricing: Free forever for invoicing. Up to 1,000 invoices per year, unlimited clients. Other Zoho modules (Books, CRM) are paid.
Zoho Invoice is the underrated free option. Unlike Wave, it has not been absorbed into a tax-prep giant, and Zoho continues to maintain it as a free product to feed into the rest of their suite. You get recurring invoices, multi-currency, time tracking, expense logging, and a client portal — all free.
Pros:
- Permanent free tier with generous limits
- Multi-currency and multi-language support
- Client portal where customers see and pay invoices
- Integrates with Stripe, PayPal, Razorpay, and more
Cons:
- Requires a Zoho account and cloud sync
- Interface can feel cluttered if you are used to native iOS apps
- Free tier is a funnel to the paid Zoho ecosystem
Best for: Freelancers working with international clients, multiple currencies, or those who want a client-facing portal without paying.
6. Invoice Ninja — Best Open-Source Option
Pricing: Free self-hosted (you run the server). Hosted Forever Free tier covers up to 20 clients. Paid plans from $11/month.
Invoice Ninja is the open-source play. If you are technical enough to spin up a server, you get a full invoicing platform with no vendor lock-in, no upsells, and full data ownership. The hosted free tier is decent but capped at 20 clients.
Pros:
- Open source — audit the code yourself
- Self-hosted option means total data control
- Recurring invoices, proposals, projects, and tasks included
- Active developer community
Cons:
- Self-hosting requires Linux server skills
- Hosted free tier capped at 20 clients
- UI is functional, not polished
Best for: Technically inclined freelancers, developers, and consultants who value data ownership.
7. Square Invoices — Best Free for In-Person Payments
Pricing: Free invoicing. Payment processing 3.3% + $0.30 for cards-on-file, 2.6% + $0.10 for in-person tap. Optional Plus plan $35/month.
Square Invoices is the right pick if you also take in-person payments — trade workers, mobile service providers, photographers shooting events. The free tier sends unlimited invoices and integrates with the Square card reader. If you run a service business that mixes site-visits and office-based billing — think LawnBook for lawn care operators, ShineBook for cleaning crews, or TrestleBook for contractors juggling job costing — Square's tap-to-pay plus invoicing combo is hard to beat.
Pros:
- Free unlimited invoices
- Excellent for in-person + invoice hybrid workflows
- Same dashboard as the Square POS
Cons:
- Card-on-file processing fee (3.3%) is higher than competitors
- Plus plan needed for milestone payments and custom contracts
- Geared toward retail/service businesses more than pure knowledge work
Best for: Service-based freelancers who collect a mix of in-person and remote payments.
How We Picked These Apps
We focused on four criteria that matter to working freelancers:
- Real free tier — not a 14- or 30-day trial pretending to be free. We made an exception for FreshBooks and QuickBooks because they keep showing up in "free invoicing" searches and freelancers deserve to know they are paid products.
- Solo-friendly — built for one person, not a 20-seat agency. The pricing, UI, and feature set should reward simplicity.
- Invoice-to-paid workflow — can you actually get paid without bolting on three other tools?
- Data ownership — who owns the data, where it lives, and what happens if the company gets acquired (something Wave users learned the hard way).
Apps that fail on any of these — or that quietly nerfed their free tier in the last 18 months — were left off. We also skipped pure payment processors like Stripe Invoicing because they do not handle the time tracking or expense logging side of a freelance workflow.
Which App Is Right for You?
The honest answer depends on what kind of freelancer you are.
If you are a solo freelancer who values privacy, offline use, and zero subscriptions: Stintly is the cleanest fit. Track time, log expenses, send a PDF invoice, done. No account, no monthly fee, no cloud sync.
If you want bookkeeping baked into invoicing: Wave still offers the strongest free accounting bundle, though customer support has degraded since the H&R Block acquisition.
If you have multiple international clients and need a client portal: Zoho Invoice is the most generous web-based free tier on the market.
If your invoicing pain is really a tax pain: QuickBooks Solopreneur or working with an accountant directly will serve you better than chasing a free app.
If you run a hybrid service business with in-person and remote billing: Square Invoices is the answer. Operators in trades adjacent to ours — landlords on KeyLoft handling tenant move-in fees, or solo cleaners and lawn-care pros — tend to need that in-person + invoice mix.
For most solo freelancers reading this in 2026, the calculus is simple: you do not need a $20/month subscription to send a PDF invoice. Start free, see if your invoicing pain actually needs a more complex tool, and only pay when the free option breaks. Most of the time, it never will.
