Every freelancer eventually hits the same wall: the spreadsheet stops working. You have four active clients, two of them owe you money, one wants a revised invoice, and you cannot remember whether you already billed for that extra round of edits. So you go looking for an invoicing app, and you discover that "free" means seven different things depending on who is selling it.
Some apps are free until you send your third invoice. Some are free but take a percentage of every payment. Some are genuinely free and make money elsewhere. And some are free trials wearing a costume. This roundup sorts them out. We looked at seven invoicing tools freelancers actually use in 2026, tested what happens when you push past the free tier, and wrote down what we found — including the parts that make our own app look worse.
1. Stintly — Best Free Option for Solo Freelancers
Stintly is a time tracking and invoicing app built for one person working alone. You track hours against a client or project, mark expenses, and generate an invoice from the logged time. No account, no login screen, no cloud sync. Everything lives on your device.
Pricing: Free. There is no paid tier, no invoice cap, no client cap, and no transaction fee. The app makes no money from your invoices.
Why it wins for freelancers: The competition on this list is mostly small-business accounting software that added invoicing. Stintly is the opposite — it starts from the freelancer's actual daily loop, which is track time, bill time, get paid, repeat. There is no chart of accounts to configure, no bank feed to reconcile, no onboarding wizard asking whether you are an LLC. You open it, start a timer, and by Friday the invoice is mostly written for you.
Offline-first matters more than it sounds. If you work from client sites, trains, coworking spaces with hostile wifi, or anywhere the signal drops, your data is on your phone and stays usable. Nothing waits on a sync.
Honest cons: Stintly does not do payment processing. It generates the invoice; the client pays you through whatever method you already use — bank transfer, PayPal, Stripe link, check. If you want a "Pay Now" button that charges a card inside the invoice, Stintly cannot do that, and Wave or FreshBooks can. It also does not do full double-entry bookkeeping, bank reconciliation, or payroll. Because data is local, there is no web dashboard and no automatic multi-device sync — you manage your own backups. And it is iOS only. Android freelancers should skip to Wave or Zoho.
The trade is deliberate: you give up the accounting suite and get an app that opens fast, never nags you to upgrade, and does not hold your invoice history hostage behind a subscription.
Stintly is free to download. Download Stintly for Free — no account needed, works offline.
2. Wave — Best Free Option with Built-In Payments
Wave has been the default "free invoicing" answer for years, and it earns the spot. You get unlimited invoices, unlimited clients, recurring billing, and a genuine double-entry accounting ledger behind it — the kind of thing you would otherwise pay for.
Pricing: The Starter plan is free for invoicing and basic accounting. The Pro plan runs roughly $16/month and adds automatic bank import, receipt scanning, and lower card rates. Payment processing is the real cost: about 2.9% + $0.60 per card transaction, and roughly 1% for ACH bank payments. Send a $3,000 invoice, pay about $87 to get paid by card.
Pros: Clients click a button and pay. Invoices look professional. Recurring invoices handle retainer clients without you touching anything. The accounting side means your accountant can actually work with the export at tax time. Works on web and mobile, Android included.
Cons: Wave is cloud-only, so no internet means no invoicing. Payment fees add up fast on large invoices — freelancers billing $5k+ per project often find it cheaper to invoice for bank transfer and eat the slower payment. Time tracking is weak; there is no real timer, so you are entering hours by hand or importing from another tool. Support on the free plan is thin. And Wave has narrowed availability over the years, so payments and payroll are not supported everywhere.
Pick Wave if: you want clients to pay by card instantly and you are fine paying a percentage for that convenience.
3. QuickBooks Solopreneur — Best for Tax-Heavy Freelancers
QuickBooks retired the old Self-Employed product line into what it now calls Solopreneur, aimed at the same person: a sole proprietor who files a Schedule C and wants the tax math handled.
Pricing: Around $20/month for Solopreneur, frequently discounted to a few dollars for the first three months. Simple Start sits near $38/month if you outgrow it. There is no free tier — only a 30-day trial. Card payments run roughly 2.9% plus a fixed fee.
Pros: The quarterly estimated tax feature is the reason people pay. It watches your income and expenses, estimates what you owe the IRS, and reminds you before each deadline. Automatic mileage tracking via GPS is genuinely good if you drive for work. Bank and card feeds import transactions and let you swipe business or personal. Every accountant in the US already knows QuickBooks.
Cons: It is not free and never becomes free. Invoicing is functional but plain, and customization is limited compared to FreshBooks. Time tracking is basic unless you add QuickBooks Time, which costs extra. Prices have climbed steadily. The upsell pressure inside the product is constant. And if you are not in the US, the tax features lose most of their value.
Pick QuickBooks if: quarterly taxes stress you out more than $20/month does.
4. FreshBooks — Best for Client-Facing Polish
FreshBooks started as invoicing software and it shows. If your invoice is part of how clients perceive you — designers, consultants, agencies of one — this is the most presentable option on the list.
Pricing: Lite starts around $21/month for up to 5 billable clients, Plus around $38/month for 50, Premium around $65/month for unlimited. There is a 30-day free trial, no free tier. Card processing is about 2.9% + $0.30, ACH around 1%.
Pros: The best invoicing experience here. Templates look designed rather than generated. Built-in timer, project tracking, expense capture, and proposals all connect to the invoice. Automated late payment reminders and late fees run without you sending the awkward email. Client portal lets people see invoices and payment history in one place.
Cons: The client limit on the Lite plan is a real constraint — a freelancer with a dozen small clients gets pushed to a $38/month plan quickly. Each extra team member costs about $11/month. It is more accounting tool than you may need if you just bill hours. And once your invoice history lives there, leaving is painful.
Pick FreshBooks if: your invoices are a client touchpoint and you bill enough that $21–$38/month is noise.
5. Zoho Invoice — Best Truly Free Cloud Option
Zoho Invoice is the surprise of this category: a full-featured cloud invoicing app that costs nothing, permanently. Zoho gives it away to pull you into the rest of its software ecosystem.
Pricing: Free, with no invoice limit. You pay only the payment gateway's own fees if you connect Stripe or PayPal, since Zoho does not add a cut.
Pros: Unlimited invoices and customers on the free plan. Built-in timers and timesheets that convert to invoices. Multi-currency, multi-language, recurring invoices, customer portal, expense tracking, and automated reminders. Web plus solid iOS and Android apps.
Cons: The interface is dense — Zoho builds for feature coverage, not simplicity, and there is a learning curve. It is invoicing only, so no bookkeeping, and the natural upgrade path is Zoho Books at roughly $15–$20/month. Support is documentation-heavy. And the whole thing pulls you toward adopting more Zoho products.
Pick Zoho Invoice if: you want cloud sync and unlimited free invoices, and you do not mind clicking through a busier interface.
6. Invoice Simple — Best for Occasional Invoicing
Invoice Simple does exactly what the name says. Open app, fill in fields, send PDF. No accounting, no projects, no ledger.
Pricing: Free for your first few invoices — typically three — then roughly $8–$15/month depending on plan and platform. The free tier is a sampler, not a plan.
Pros: The fastest path from "I need to bill someone" to a sent invoice. Templates look fine. Estimates convert to invoices in a tap. Good for trades and service work where the invoice is written on site. Works on iOS, Android, and web.
Cons: The free tier runs out almost immediately, which makes its inclusion on a "free apps" list generous. No real time tracking. No expense or profit reporting. If you invoice weekly you will be paying, and at that point the feature set is thin relative to price.
Pick Invoice Simple if: you send a handful of invoices a year and want zero setup.
7. Bonsai — Best for Contracts Plus Invoicing
Bonsai bundles the paperwork side of freelancing: contracts, proposals, e-signatures, invoices, and light bookkeeping in one subscription.
Pricing: Starts around $25/month billed annually, with higher tiers near $39–$79/month. Free trial only, typically 7–14 days.
Pros: The contract templates are lawyer-reviewed and freelance-specific, which is worth real money if you have ever been burned on scope. Proposal, contract, and invoice chain together, so signing a proposal starts the billing. Automated late fees and payment reminders included.
Cons: Most expensive option here and there is no free tier at all. If you already have contracts you are happy with, you are paying for redundancy. Accounting features are shallower than QuickBooks. Overkill for anyone billing a small number of long-term clients.
Pick Bonsai if: you sign new clients often and want contracts and invoices in one place.
How We Picked These Apps
Four criteria, applied in order.
- What "free" actually means. We separated permanently free tiers from trials and from freemium caps you hit in week one. An app that gives you three invoices is not a free invoicing app, and we said so.
- Total cost to get paid. Subscription price is only half the number. A free app charging 2.9% on a $4,000 monthly invoice load costs about $120/month — more than any subscription here. We listed processing fees for every app that has them.
- Fit for one person. These tools all scale up to teams. We judged them on how well they work for a single freelancer with somewhere between two and fifteen clients — which usually means penalizing apps that make you configure accounting infrastructure before sending an invoice.
- Time-to-invoice. How many steps between finishing work and having a bill in a client's inbox. Apps that track time natively win here, because the hours are already in the system.
We did not weight integrations heavily. Most freelancers connect an invoicing app to nothing, and features you never turn on should not decide the ranking.
One note on scope: this list is for general freelance and consulting work billed by hour or project. Trade businesses have different needs — job costing, materials, crew hours, recurring service routes — and a general invoicing app handles them badly. If you run a lawn care operation with route scheduling and seasonal contracts, LawnBook is built for that. Cleaning businesses juggling residential and commercial jobs get closer fit from ShineBook. Landlords tracking rent, leases, and tenant communication want KeyLoft rather than an invoicing tool. And contractors who need to bill against job phases and track cost per project should look at TrestleBook. Same philosophy as Stintly — built for one trade rather than stretched across all of them.
Which App Is Right for You?
Match the app to how you actually work, not to the longest feature list.
- You bill hourly and want zero cost, zero setup: Stintly. Track time, generate the invoice, keep everything on your device. Best fit if you are on iOS and get paid by bank transfer.
- You need clients to pay by card immediately: Wave. Free to send, and the processing fee buys you speed. Best fit if your invoices are small enough that 2.9% does not sting.
- Quarterly taxes are your main problem: QuickBooks Solopreneur. The estimate-and-remind loop is worth $20/month if it stops you underpaying the IRS.
- Your invoice represents your brand: FreshBooks. Best-looking output, best automation around late payments, priced accordingly.
- You want free plus cloud sync across devices: Zoho Invoice. Unlimited and genuinely free, at the cost of a busier interface.
- You invoice a few times a year: Invoice Simple. Do not pay a subscription for something you open twice a quarter.
- You sign new clients constantly: Bonsai. The contract layer is the actual product.
A practical suggestion: start free and let real friction push you to upgrade. Most freelancers who pay $30/month for invoicing software are using about a fifth of it. Run Stintly or Zoho Invoice for a full quarter first. If you get to the end of that quarter and the only thing you wanted was a card payment button or automatic tax estimates, you now know exactly what you are buying and why — instead of paying for an accounting suite because a comparison chart had more checkmarks in it.
The other thing worth saying plainly: invoicing software does not fix late payment. No app on this list makes a slow-paying client fast. Clear payment terms, a deposit up front, and a follow-up you actually send do more for your cash flow than any feature here. Pick the tool that gets the invoice out the door on the day the work finishes, and spend the saved effort on the terms you agree to before the work starts.
