6 Best Invoicing Tools for Freelancers and Solopreneurs in 2026
Chasing payments is the least fun part of running a freelance business. Here are six invoicing tools that automate the admin, look professional, and actually...
Invoicing is something freelancers do reluctantly and clients pay slowly. The right tool won't fix the slow-payer problem, but it can automate the reminders, track what's outstanding, handle recurring billing, and make you look more professional — which quietly helps you get paid faster.
Quick answer: Wave is the best free invoicing tool for freelancers — unlimited clients, recurring billing, and basic bookkeeping at no cost. Use Bonsai if you also write contracts and proposals regularly, and FreshBooks when you bill hourly and need a smooth time-tracking to invoice workflow.
Here are six invoicing tools worth using if you're a freelancer, consultant, or early-stage solopreneur.
1. Wave
What it is: Free invoicing and accounting software for freelancers and small businesses. Invoices, estimates, receipt scanning, basic accounting, and payroll (in Canada/US).
Best for: Freelancers who want professional invoicing and basic bookkeeping at zero cost. Especially useful in the US and Canada where the payroll features are available.
Pricing: Free for invoicing and accounting. Payment processing fees apply (2.9% + $0.60 for credit cards).
Why it stands out: Wave is genuinely free — not free-with-limitations. The invoicing, recurring billing, expense tracking, and basic accounting reports cost nothing. For a solo freelancer billing 10-20 clients per month, Wave covers all the invoicing and basic bookkeeping without a subscription. The payment processing fees are standard market rates.
Limitation: The accounting features are basic — they work but won't satisfy an accountant who needs GAAP-compliant bookkeeping. The UX feels dated compared to FreshBooks. Customer support is limited on the free plan.
2. Bonsai
What it is: All-in-one freelancer platform — contracts, proposals, invoices, time tracking, and a basic CRM — built specifically for freelancers and agencies.
Best for: Freelancers who want to manage the entire client engagement lifecycle in one tool: proposal → contract → project tracking → invoice → payment.
Pricing: From $21/mo (Starter).
Why it stands out: Bonsai's contract templates are its best feature. Freelance-specific agreements for design, development, writing, photography, and consulting — legally reviewed, customizable, and professional. Combined with invoicing and proposal generation in the same tool, it reduces the end-to-end time from "client says yes" to "invoice sent" significantly. If you're writing new contracts from scratch each engagement, Bonsai pays for itself quickly.
Limitation: Overkill if you only need invoicing. The $21/mo is hard to justify for a freelancer who already has contracts sorted and just needs to send invoices. Wave or Invoice Ninja handle invoicing-only at lower cost.
3. FreshBooks
What it is: Cloud accounting and invoicing platform designed for self-employed professionals and small business owners. Strong invoicing, time tracking, expense management, and double-entry accounting.
Best for: Freelancers who bill hourly, need to track time against projects, and want invoices that generate automatically from tracked time. Also good for teams of 2-5 who need proper accounting.
Pricing: From $17/mo (Lite, up to 5 clients). Scales with client volume.
Why it stands out: FreshBooks' time tracking → invoice flow is the smoothest available. Track hours against a project, hit "Create Invoice," and the billable time populates automatically. For hourly-rate freelancers, this removes the most friction-heavy part of billing. The UX is polished, client-facing invoices look professional, and automatic payment reminders run without manual intervention.
Limitation: The Lite plan is capped at 5 active clients — a real constraint for freelancers with more than that. Moving to the Plus plan ($30/mo) for unlimited clients is a meaningful price jump.
4. Invoice Ninja
What it is: Open-source invoicing and billing platform. Self-hostable or cloud-hosted. Invoices, recurring billing, time tracking, expenses, and a client portal.
Best for: Technical freelancers who want full data ownership and zero ongoing cost. Also good as a cloud-hosted tool for freelancers who want clean invoicing without FreshBooks pricing.
Pricing: Self-hosted: free. Cloud: free up to 20 clients (Ninja plan). From $10/mo (Pro).
Why it stands out: The free cloud plan is more generous than almost any competitor — 20 active clients with full invoicing, recurring billing, and a client portal. Self-hosting is a real option for technical users who want to own their financial data. The client portal (where clients can view invoice history, download PDFs, and pay online) is a genuinely professional touch.
Limitation: The UX is functional but not polished compared to FreshBooks or Bonsai. Self-hosting requires maintenance. The free tier's 20-client limit is lower than Wave's unlimited.
5. Stripe Invoicing
What it is: Invoicing built directly into Stripe. Send invoices via email, clients pay with any card or bank transfer, and revenue flows directly into your Stripe account.
Best for: Founders and freelancers who already use Stripe for product payments and want to consolidate invoicing into the same platform. Also good for one-off invoices where you don't want to set up a dedicated invoicing tool.
Pricing: 0.4% per invoice paid (capped at $2/invoice on most paid invoices). Payment processing fees on top.
Why it stands out: Zero monthly fee. You pay only when you get paid. If you already have a Stripe account, you're one click from sending a professional invoice. The client experience is polished — a mobile-friendly payment page that accepts cards, bank transfers, and BNPL. For ad hoc invoicing (not recurring billing), Stripe Invoicing is the lowest-friction professional option.
Limitation: Not a replacement for dedicated invoicing software if you need expense tracking, time tracking, or an accounting ledger. The percentage fee can exceed a flat subscription cost at high invoice volumes.
6. Toggl Track + Invoice Integration
What it is: Toggl Track is time tracking software with a report-to-invoice workflow. Track time, generate reports, and export to FreshBooks, Xero, or QuickBooks for invoicing.
Best for: Freelancers who need accurate time tracking first and invoicing second. Especially useful when billing clients with detailed timesheets (agencies, consultants, lawyers).
Pricing: Free tier (unlimited tracking). Starter from $10/user/mo for team features.
Why it stands out: Toggl Track's free tier covers unlimited time tracking, projects, and clients. The reports show exactly how time was spent — by project, by client, by tag — which is exactly what a detailed invoice needs. Combined with FreshBooks or Invoice Ninja for actual billing, it gives you the most accurate timesheet-to-invoice workflow available.
Limitation: Not a standalone invoicing tool — it's time tracking that integrates with invoicing tools. You need two products for the full workflow.

Frequently Asked Questions
Do I need accounting software or just invoicing software?
Invoicing only for most freelancers — especially if you have an accountant who handles your annual filing. Add accounting features (Wave or FreshBooks full suite) if you want to track profit/loss yourself, need expense management, or have complex tax situations.
What payment methods should I offer clients?
Credit card and bank transfer (ACH) as minimum. Cards pay faster but cost 2.9% + $0.30. ACH is cheaper (typically 0.8% capped at $5) but takes 2-5 business days. Offer both and let clients choose.
How do I get clients to pay faster?
Set payment terms upfront (Net 15 not Net 30 is the move). Require a deposit (50% upfront is standard for project work). Set up automatic reminders 3 days before due, on due date, and 3 days after. All the tools above support automatic reminders.
Should I charge late fees?
State them in your contract — even if you never enforce them, the policy signals that you're serious about payment timing. 1.5% per month is a common rate. FreshBooks and Bonsai both support automatic late fee calculation.
