What to look for in invoicing software as a solo freelancer
Most invoicing software is built for small businesses with employees, not for solo freelancers. The result is a category full of tools that have features you do not need (payroll, multi-user permissions, vendor bills) and miss features you do (built-in time tracking, quarterly tax estimates).
A good invoicing tool for one-person freelancing covers four things, and a great one keeps the price under $10 a month while doing them.
Time tracking that flows into invoices
Most freelancers bill hourly at least some of the time. Tools without time tracking force you to use a separate app, then copy hours over manually.
Online payments via Stripe or similar
Card payment links cut your average payment time roughly in half versus bank transfers. Stripe at 2.9% + 30¢ is the industry standard.
Expense tracking and tax summaries
Tax season is the actual hard part of freelancing. A tool that tracks expenses and estimates quarterly taxes saves an accountant bill or a panic in April.
Pricing that fits a one-person business
$9–$15 a month is reasonable. $19–$30 a month is what tools built for small business teams charge, and you usually pay for features you do not use.
FreelanceFlow — built specifically for solo freelancers
FreelanceFlow is the tool we make. The pitch is narrow on purpose: invoicing, time tracking, online payments, expense tracking, and quarterly tax estimates, with nothing else getting in the way.
Free plan includes invoicing, time tracking, and client management. Pro plan is $9 per month (or $7.20 a month billed annually) and adds unlimited invoices, Stripe-powered online payments, and tax summaries. Stripe charges its standard 2.9% + 30¢ per transaction; FreelanceFlow does not add anything on top.
Best for: a freelancer who wants one tool that covers the whole money side of the business and bills them like one person, not a team.
FreshBooks — feature-rich but built for small businesses
FreshBooks is the legacy player in this space. It has a deep feature set including double-entry accounting, vendor management, and team collaboration features that solo freelancers will never use.
Pricing starts at $19 per month for the Lite plan, which limits you to five billable clients. Higher tiers ($33, $60) raise that cap and add features. There is no free plan — only a 30-day trial.
Best for: a freelancer planning to grow into a small agency with employees or contractors. For a solo freelancer who wants a free starting point and a tighter price, FreelanceFlow covers the same core features at less than half the cost.
Wave — free, but missing time tracking
Wave's invoicing is genuinely free. Its monetization comes from per-transaction payment fees and from selling payroll and bookkeeping services as add-ons.
What Wave does not have is time tracking. For a freelancer who bills hourly, that means using Wave plus a separate time tracker (Toggl, Harvest) and copying hours over by hand. The 'free' price gets eaten by the time cost of running two tools.
Best for: freelancers who only bill flat rates and never track hours. For anyone who tracks time, FreelanceFlow's $9 plan eliminates the second tool entirely.
Harvest — strong time tracking, weak for solo billing
Harvest is a time tracking tool with invoicing bolted on, designed for teams with managers and capacity planning. Pricing starts at $11 per seat per month after a limited single-seat free plan.
For a solo freelancer, the team features (approvals, capacity planning, manager dashboards) are noise. The tax estimation features that matter for self-employment are not there at all.
Best for: a small agency or studio billing by tracked hours. For solo freelancers, the per-seat pricing gets expensive fast and the tax features are missing.
Toggl Track — excellent at time tracking, nothing else
Toggl Track is the gold standard for time tracking specifically. Free plan covers basic tracking; the Starter tier at $9 per seat per month adds project tracking and reporting.
Toggl does not invoice, accept payments, track expenses, or estimate taxes. It is one tool that solves one problem extremely well — and you would still need three or four other tools for the rest of your freelance billing.
Best for: freelancers who want best-in-class time tracking and are willing to use other tools for invoicing and payments. For everyone else, FreelanceFlow at the same $9 price covers all five jobs.
HoneyBook — client management for creative businesses
HoneyBook is built for creative service businesses (wedding photographers, event planners) that need contracts, proposals, scheduling, and automated workflows alongside invoicing.
Pricing starts at $19 per month with no free plan. Time tracking is not included.
Best for: creative freelancers who run formal client workflows with contracts and proposals as part of their sales process. For freelancers who do not need that complexity — just track time, send invoices, get paid — HoneyBook is overbuilt.
QuickBooks Self-Employed — accounting, not invoicing-first
QuickBooks Self-Employed is positioned for freelancers but is fundamentally accounting software. Pricing starts at $15 per month after a trial.
It has invoicing, expense tracking, and tax estimates. It also has a learning curve typical of accounting software — features like categorizing transactions and tax bracket modeling expect you to think like a bookkeeper. Time tracking is limited.
Best for: freelancers who want a Schedule C optimized for at filing time and are comfortable with accounting concepts. For freelancers who want a simpler tool with the same essentials, FreelanceFlow at $9/month covers the use case without the accounting overhead.

Solo freelancer who bills hourly
FreelanceFlow — built-in time tracking, automatic time-to-invoice, free plan to start, $9/month for full features.
