Invoicing sounds like a solved problem until you’ve actually run a freelance operation for a year. Then you notice the things nobody mentions in the feature grids: the tool that charges you for a second client login, the “free” plan that charges 3.49% plus 49 cents per card payment, the mobile app that loses half your line items when you lose signal on a job site, the export file that won’t reconcile with your accountant’s software.
I’ve set up and torn down invoicing software for freelance operations and small consultancies more times than I’d like to count. What follows is an honest look at eight platforms, with attention to the things that actually matter after day 90 — not day three.
A note on methodology: I used each of these tools for real billing work across a mix of hourly consulting, fixed-fee projects, and retainer clients over a period of weeks, not days. I did not run benchmarks in a lab, and I don’t trust anyone who claims to have. Where I mention pricing, it’s what was listed on the vendor’s site at the time of writing — check before you commit, because SaaS pricing moves quarterly.
Quick Verdict
Best overall: FreshBooks — if you bill hourly and want time tracking and invoicing in one tool, this is the least painful option. It’s not the cheapest, and the per-client limits on the lower tier are annoying.
Best free option: Wave — genuinely free for the core invoicing workflow, with reasonable card processing rates. Support is slow and the roadmap has been quiet, which is worth knowing before you commit.
Best for mobile-first work: Invoice2go — the only tool here where I felt the mobile app was the primary experience, not a compromise. Web interface is noticeably weaker.
Avoid unless you already use the ecosystem: PayPal Invoicing and Square Invoices. Both are fine as bolt-ons if you’re already in those ecosystems, but I would not build an invoicing workflow around either.
How I Evaluated Each Tool
For each platform, I set up an account from scratch, imported a small client list, generated a handful of invoices across different billing models, tested the client-side payment experience from a different browser and device, ran a partial month of recurring invoices, and tried to export the data out. That last step is the one most reviews skip, and it’s the one that tells you whether you’re locked in.
I paid particular attention to: how long it actually takes to get from “new account” to “first invoice sent,” what happens when your internet drops mid-invoice, whether the client portal works on mobile, and how the platform handles the annoying real-world cases — partial payments, late fees, refunds, currency mismatches.
Comparison Table
| Platform | Best For | Starting Price (USD) | Free Plan | Card Processing (US) |
|---|---|---|---|---|
| FreshBooks | Hourly freelancers | ~$8.50/mo (Lite) | 30-day trial | 2.9% + 30¢ |
| Wave | Solo, low volume | Free | Yes | 2.9% + 60¢ |

Prices are US list as of the time of writing. Always verify current pricing at the source before committing — every one of these vendors raised prices at least once in the last two years, FreshBooks and QuickBooks more than once.
FreshBooks — Best Overall for Hourly Freelancers
FreshBooks is the tool I end up recommending most often for freelancers who bill by the hour, mainly because the timer-to-invoice workflow is the tightest I’ve used. You start a timer on a client, work, stop it, and the hours land on an invoice without manual re-entry. That alone saves real time — not the cartoonish “10 hours a week!” that marketing pages throw around, but fifteen or twenty minutes per billing cycle that you’d otherwise spend reconciling timesheets.
Pricing (US): Lite is around $8.50/month for up to 5 billable clients, Plus jumps to around $15/month for 50 clients, Premium around $27/month for unlimited. Numbers move with promotions, and FreshBooks pushes annual billing hard — the monthly price you see after the trial is usually higher than the promo.
Where it genuinely helps: The client portal is the best in this roundup. Clients can see past invoices, download PDFs, and pay without creating an account. I saw clients pay faster when I switched to FreshBooks — not because of any magical reason, but because one-click “Pay this invoice” is less friction than “find the PDF, open your bank portal, type in the reference number.”
Where it falls short: The client limit on Lite is the classic land-and-expand move. Five clients sounds generous until you realize that an archived client still counts against the limit on some plans unless you actively delete them, and deleting them nukes historical reporting. Plan on upgrading to Plus within your first year if you’re serious about freelancing. Also: FreshBooks does not do real double-entry accounting well, and the “accounting” features added to higher tiers feel grafted on. If you expect your bookkeeper to love it, ask them first. For freelancers who need a full accounting layer alongside invoicing, our best accounting software for freelancers comparison covers Zoho Books, Xero, and FreshBooks side-by-side.
The other thing worth flagging: exporting your data out of FreshBooks is possible but fiddly. You can export invoices and clients to CSV, but the format doesn’t drop cleanly into QuickBooks or Xero without cleanup. This is the vendor lock-in tax — it’s not catastrophic, but don’t assume a migration away will take an afternoon.
Wave — Best Free Option, With Caveats
Wave is genuinely free for invoicing and basic accounting. No seat limits, no invoice caps, no “upgrade to unlock.” They make their money on payment processing and payroll, and if you send clients bank-transfer or ACH links (which cost 1% in the US) rather than card payments, Wave is effectively free to operate.
Where it genuinely helps: The free tier is not a “land you into a paid plan” funnel the way most free tiers are. I’ve run a side business on Wave for over a year without paying a cent. The double-entry accounting layer, while basic, is real — your invoices actually post to an income account, which means tax time is less of a scramble.
Where it falls short: Wave has felt stagnant for the last couple of years. Feature releases are infrequent, customer support on the free tier is essentially self-serve (there’s a paid Advisors tier if you need real help), and the mobile app is weaker than the web product. If you send more than a handful of invoices a month and rely on responsive support when something breaks, Wave will frustrate you. The card processing rate of 2.9% + 60¢ is also worse than most competitors on the per-transaction fixed cost — that extra 30 cents adds up on small invoices.
One more thing: Wave doesn’t have built-in time tracking. If you bill hourly, you’re manually entering line items, which defeats a lot of the workflow value.
Invoice2go — Best for Mobile and Field Work
Most “mobile apps” from invoicing vendors are web apps in a wrapper. Invoice2go actually started as a mobile product, and you can feel it. If you’re a trade, contractor, photographer, or anyone who creates invoices on a phone between jobs, this is the tool that will annoy you the least.
Pricing (US): Starts around $6/month for the basic plan, with higher tiers around $13/month and $20/month adding more features and users. Promotional pricing is common — check the real post-trial number.
Where it genuinely helps: Offline invoice creation works. I tested it on a flight, created an invoice, closed the app, reopened on landing — it synced without drama. The ability to attach photos to line items (useful for “here’s the damage before I started” documentation) is a nice touch that other tools don’t prioritize.
Where it falls short: The web interface feels like an afterthought. If you also want a desktop workflow — sitting down on a Sunday night to batch-invoice the week — you’ll be fighting the tool. There’s also no built-in time tracking, and the integrations with accounting software are thin. You’re more or less expected to export to your accountant once a quarter rather than live-sync.
And the pricing structure is classic land-and-expand: the cheap tier is cheap, but some of the features a working freelancer will want — multi-user, advanced reporting, integrations — sit in the mid and top tiers. Map out what you actually need before assuming the entry price is your price.
Zoho Invoice — Free and Capable, If You Can Tolerate the UI
Zoho Invoice is free. Not trial-free, not free-with-an-asterisk — actually free for the invoicing workflow, because Zoho’s strategy is to use it as a top-of-funnel for their broader suite (Zoho Books, Zoho CRM, Zoho One).
Where it genuinely helps: Feature-for-feature, this is more capable than Wave: client portal, recurring invoices, multi-currency, automated reminders, and workflow rules that trigger actions on events. If you already use anything in the Zoho stack — CRM, Projects, Books — the integration is native and works well.
Where it falls short: The Zoho UI is an acquired taste. It’s dense, it uses its own design conventions, and it does not feel modern compared to FreshBooks or Wave. The mobile app is functional but not a delight. The real tax comes later: Zoho Invoice is free because Zoho expects you to eventually buy Zoho Books, or Projects, or Zoho One. Nothing wrong with that, but don’t assume this is a forever-free tool with no strings. The strings are just further down the road.
Payment processing isn’t built in — Zoho routes through Stripe, Razorpay, PayPal, or similar, which is honest but means you’re managing a second vendor relationship for card payments.
QuickBooks Online — For Freelancers Ready to Become a Small Business
QuickBooks Online is an accounting system that happens to have invoicing. If you’re looking at this list and thinking “I just want to send invoices,” QBO is overkill. If you’re thinking “I’m starting to look more like a small business and I need my bookkeeper to stop yelling at me,” it’s appropriate.
Pricing (US): Simple Start starts around $35/month, Essentials around $65, Plus around $99, Advanced north of $235. Intuit runs aggressive first-year discounts that evaporate on renewal — a Simple Start plan advertised at $9/month for three months will be $35/month by month four. Budget for the real price, not the promo.
Where it genuinely helps: If you have an accountant, they probably already use QuickBooks. That alone can justify the price, because the cost of your accountant spending two extra hours a month fixing your Wave export is higher than the QBO subscription. Bank feeds, reconciliation, sales tax handling, and 1099 prep are all solid.
Where it falls short: The invoicing UI specifically is clunkier than FreshBooks or Invoice2go. You can tell it was built inside an accounting paradigm, not a freelance workflow. Payment processing fees are marginally better on the fixed-cost side (25¢ vs 30¢) but the per-transaction rate ticked up to 2.99% in recent pricing changes — worse than most competitors. Price increases are constant. Customer support is a lottery. And every “advanced” feature you actually need lives in the tier above the one you’re on.
QuickBooks is the tool most people migrate to when they outgrow something simpler. Worth knowing it’s there; don’t start here unless you already know you need it.
PayPal Invoicing — Only If You’re Already There
PayPal’s invoicing is free, works, and most clients already have a PayPal account. That’s the entire case for it. It is a convenience feature for people who live in PayPal, not a dedicated invoicing platform.
Where it genuinely helps: Zero setup if you already have a PayPal Business account. Your clients almost certainly recognize the payment flow. If you send two or three invoices a month, this is more than enough.
Where it falls short: The processing fees are the worst in this roundup for US card payments — 3.49% + 49¢ per transaction. On a $500 invoice, that’s nearly $18 to PayPal versus about $15 through a competitor at 2.9% + 30¢. That gap widens if you send a lot of invoices, and it’s pure margin you’re burning. Customization is minimal, reporting is thin, and PayPal’s dispute resolution process has historically been slow and unfriendly to merchants. Account freezes, while rare, are a real risk — and if PayPal is both your invoicing tool and your payment processor, a freeze takes out your whole cash flow.
Do not build a freelance business around PayPal Invoicing. Use it as a fallback.
Square Invoices — Fine If You Already Use Square
Same logic as PayPal: if you already run a Square point-of-sale for in-person payments, the Square Invoices add-on is free and gives you a unified view of payments. The product catalog you built for the POS feeds into invoice line items, which is genuinely convenient.
Where it falls short: Outside the Square ecosystem, there’s no reason to pick this. Customization is limited, there’s no time tracking, the client portal is basic, and Square’s card processing fees for invoiced payments sit around 3.3% + 30¢ in the US — higher than FreshBooks or Wave on the percentage side. It’s a decent “I already use Square” add-on and a bad “this is my main invoicing tool” choice.
Honestly, between PayPal Invoicing and Square Invoices, I’d rank Square slightly higher for the product catalog integration, but both belong in the “only if you’re already committed to the ecosystem” bucket.
Xero — The Accountant’s Favorite, Not the Freelancer’s
Xero is a full double-entry accounting system, and like QBO, it treats invoicing as one workflow among many. The difference is that Xero’s invoicing UI is noticeably cleaner than QuickBooks’, and the product itself is better-loved by bookkeepers outside the US.
Pricing (US): Early plan around $20/month with a cap of 20 invoices per month, Growing around $47/month unlimited, Established around $80/month. Note the invoice cap on the entry tier — that’s real, and it catches people off guard when they get a “you’ve hit your limit” message on the 21st invoice.
Where it genuinely helps: Bank reconciliation is excellent, multi-currency handling is the best in this roundup, and the app marketplace is large. If you’re international or have any currency complexity, Xero earns its price.
Where it falls short: The 20-invoice cap on the entry tier is a gotcha. Card processing isn’t native — you route through Stripe, which works well but is a second vendor relationship. The learning curve is real; this is accounting software with an invoicing view, not the other way around. And like every full accounting tool, there’s more power than most solo freelancers will ever use.
Xero is the right answer if you want real accounting and clean invoices. It is the wrong answer if you just want to send a bill and get paid.
Which One Should You Actually Pick
If you bill hourly, mostly domestic, and want one tool for time and invoicing: FreshBooks. Accept that you’ll probably end up on the Plus tier within a year.
If you send a handful of invoices a month and want to spend zero dollars: Wave. Know that support is thin and the product isn’t evolving quickly. Steer clients toward ACH/bank transfer to avoid the higher fixed card fees.
If you’re a trade, contractor, or anyone who creates invoices from a truck or a job site: Invoice2go. Verify the offline sync yourself before committing.
If you already live inside Zoho or are weighing Zoho One anyway: Zoho Invoice. Otherwise, it’s capable but the UI won’t make you happy.
If your accountant is already asking for QuickBooks exports: QuickBooks Online. Don’t expect it to be pleasant, expect it to be necessary.
If you’re international, multi-currency, and want real accounting: Xero. Budget for the growing tier from the start unless you truly send fewer than 20 invoices a month.
PayPal Invoicing and Square Invoices are ecosystem add-ons, not standalone choices. If someone recommends either as your primary invoicing platform, they haven’t thought about it carefully.
Things That Matter and Nobody Talks About
SSO and team access: Almost every tool here gates multi-user and SSO behind higher tiers. If you ever plan to hire a VA to handle invoicing for you, check the per-seat price and whether adding a user bumps you up a tier. The “free” tier is almost always single-user.
Data export: Every one of these tools lets you export your clients and invoices as CSV. Not all of them export them in a form another system can ingest without cleanup. Test the export before you commit. Vendor lock-in on invoicing is rarely catastrophic — it’s an invoice, the data is simple — but budget a few days for a migration, not an afternoon.
Uptime: SaaS uptime SLAs are typically 99.9%, which translates to about 8–9 hours of downtime a year. For invoicing, that’s usually fine, unless your downtime coincides with your month-end billing day. Worth knowing, not worth panicking over.
Payment processing fees are the real cost. Headline subscription prices on these tools are small compared to what you’ll pay in percentage fees over a year. Run the math: if you bill $60,000 a year and all of it goes through cards, you’re paying roughly $1,800–$2,100 in processing regardless of which platform sits on top. A “free” invoicing tool with 3.49% fees is more expensive than a $100/year tool with 2.9% fees.
The free trial is not the day-90 experience. Every tool here feels great in week one. The test is whether it still feels great when you’re reconciling a late payment, chasing a client who says they “never got the invoice,” and trying to figure out why your Stripe payout doesn’t match your invoice report. Run those scenarios deliberately during any trial period.
FAQ
Do I actually need dedicated invoicing software, or can I just use Word/Google Docs? If you send fewer than about five invoices a month and get paid by bank transfer every time, a Google Docs template and a spreadsheet is fine. You graduate to dedicated software when you start losing track of what’s paid, when you want clients to pay by card, or when chasing late payments becomes a job in itself.
How much should card processing actually cost me? For US card payments on invoiced amounts, a competitive rate is around 2.9% + 30¢ per transaction. Anything meaningfully above that (like PayPal’s 3.49% + 49¢) is worse. ACH/bank transfer, where offered, is usually 1% and capped — if you have clients willing to use it, the savings are significant.
Can I use invoicing software for recurring retainers? Yes, every platform here supports it. The mechanics vary — some auto-charge a saved card, some auto-send an invoice for manual payment. For retainers, auto-charge is much less work; for variable monthly work, auto-send is more flexible. Pick based on how your retainers actually work.
Do I need separate accounting software? If you’re a sole proprietor with simple taxes, probably not in the first year or two — Wave’s built-in accounting or a quarterly handoff of CSVs to an accountant is enough. Once you’re at a point where you’re chasing deductions, managing subcontractors, or forming an LLC or S-corp, dedicated accounting software (QBO or Xero) starts to pay for itself. Freelancers billing on mobile should also check our best invoice apps for iPhone and Android for workflow options that work without a laptop.
Will switching platforms later be painful? Yes, but manageable. The data migration itself is usually a few hours. The harder part is rebuilding recurring invoices, re-saving client payment methods (your clients have to re-authorize, which creates friction), and retraining your own workflow. Budget a week of distraction, not a day.
Does SSO matter for a solo freelancer? Not really. SSO matters when you have a team and want centralized access control. For a single user, a password manager covers the same ground. Note that SSO is almost always locked behind an enterprise tier on these tools — don’t let anyone talk you into paying up for it unless you actually have the team to justify it.
