The 8 best invoice generators for 2025

From genuinely free apps to full accounting suites and an open-source self-hosted platform, these eight invoice generators cover the widest range of billing needs a founder, freelancer, or team is likely to encounter.

1. Zoho Invoice: Best free invoice generator for small businesses

Best for: Freelancers and small teams who need unlimited, professional invoicing without paying a monthly subscription.

Zoho Invoice is a genuinely free, no-time-limit invoice generator with customizable templates, expense tracking, and a built-in client portal. It doesn’t cap the number of invoices you send or clients you bill, making it the most generous free option on this list. The customer portal lets clients view, comment on, and pay invoices directly, drastically cutting back-and-forth email. Multi-currency support and automated payment reminders work on the free plan, so you can bill international clients and gently chase late payments without lifting a finger.

2. FreshBooks: Best for service-based businesses tracking billable time

Best for: Consultants, agencies, and tradespeople who bill by the hour and want time entries to flow straight into invoices.

FreshBooks pairs invoicing with built-in time tracking that auto-populates line items on your bill, so no billable hour slips through the cracks. Recurring invoice automation and automatic late-payment reminders cut manual follow-ups for ongoing clients, and you can accept credit card payments directly on the invoice. The standout feature is the stopwatch-style timer inside the web and mobile apps that turns timesheets into unbilled entries and later into one-click invoices, keeping your revenue tied tightly to the work you actually did.

3. Wave: Best completely free invoicing + accounting combo

Best for: Solopreneurs who want unlimited invoicing and double-entry accounting without touching a paid plan.

Wave gives you free unlimited invoicing, receipt scanning, and real accounting under the hood, all without a monthly subscription. The built-in payment processing lets clients pay by credit card or bank transfer, and you pay only per-transaction fees when a payment comes through. Because it’s built on true double-entry accounting, every paid invoice automatically flows into your books, eliminating manual data entry. This is the closest you’ll get to a full financial command center for zero recurring cost.

4. QuickBooks Online: Best for businesses needing full accounting with invoicing

Best for: Growing teams that need professional invoicing as part of a larger accounting system with bank feeds and tax-ready reports.

QuickBooks Online pairs customizable invoice templates with real-time cash flow tracking, bank syncing, and automatic sales tax calculation based on location and tax rules. You can batch-invoice multiple customers, an efficiency trick that saves hours when you bill recurring clients. The standout feature is automatic bank reconciliation: as payments hit your account, QuickBooks matches them to the right invoice, slashing manual bookkeeping and giving you an always-current view of what you’re owed.

5. Invoice Ninja: Best for open-source flexibility and self-hosting

Best for: Privacy-conscious businesses or developers who want full control over their billing data and design.

Invoice Ninja comes in two flavors: a hosted SaaS plan and a completely free self-hosted version you run on your own server. Deep customization lets you tweak every design detail, set up project-based billing, track time, and connect to over 15 payment gateways. The standout feature is the self-hosted option that gives you unlimited invoices and clients with no recurring fees. You manage the server, so your data stays under your roof. It’s a rare pick for anyone who wants an invoice generator they can truly own.

6. Square Invoices: Best for businesses already in the Square ecosystem

Best for: Retailers, restaurants, and service pros who already use Square POS or hardware and want zero-friction invoicing.

Square Invoices sends estimates and bills via email, SMS, or shareable link, then syncs payment status in real time with your Square dashboard and terminal. There’s no monthly fee for invoicing. You pay a transparent per-transaction rate only when a customer pays. You can accept cards, ACH, Apple Pay, and Google Pay right on the invoice, and the system automatically updates inventory if you’re using Square for retail. If you already live in Square’s world, this invoice generator removes friction, not adds to it.

7. Xero: Best for bank reconciliation and accountant collaboration

Best for: Small businesses that work closely with an accountant and need live bank feeds alongside solid invoicing.

Xero’s invoicing integrates with daily bank feeds, so reconciliation is fast and cash flow is always visible without hours of manual imports. You can give your bookkeeper granular access to only the accounts and invoices they need without sharing login credentials, which keeps security tight. Automated invoice reminders and multi-currency billing work smoothly with Xero’s reconciliation engine, meaning you can bill international clients and still see a single, reconciled picture of what’s come in and what’s still open.

8. Invoicera: Best for multi-currency and automated recurring billing

Best for: International service providers and subscription businesses that need tiered recurring billing and dunning management.

Invoicera supports 30+ payment gateways and multi-currency billing, making it a solid pick if you invoice clients across borders regularly. Customizable workflows, client portals, and expense-tracking modules let you scale without switching tools. The standout feature is its automated recurring billing with pro-rating and dunning management: you can set up tiered subscription plans, handle mid-cycle changes, and automatically chase failed payments, keeping your cash flow predictable without a separate subscription-management stack.

How we picked these tools

I tested each invoice generator by running through the same core actions: creating a branded invoice, setting up a recurring billing profile, and tracking a payment from sent to settled. I looked at the real costs: free tier limits, hidden fees, and per-transaction charges, so “free” genuinely means usable without a surprise credit card bill. Mobile apps, offline capabilities, and integrations with payment gateways, bank feeds, and accounting syncs all mattered. I also checked basic security and compliance: HTTPS everywhere, data encryption, and whether the tool handled sales tax calculation for at least a few regions. No tool here was chosen because of a sponsorship or affiliate arrangement; each earned its spot by solving a specific invoicing problem reliably.

Frequently asked questions

What exactly is an invoice generator?

An invoice generator is software that lets you create, customize, send, and track invoices from a browser or app. Most include templates and payment options, and many also automate recurring billing and payment reminders.

Can I really get a decent invoice generator for free?

Yes. Zoho Invoice and Wave offer strong free plans with unlimited invoicing and no monthly fees. Payment processing fees still apply when clients pay by card or bank transfer, so check per-transaction rates, but you won’t pay to just create and send invoices.

Do these tools let me accept credit card and bank payments?

All listed options integrate with payment gateways like Stripe, PayPal, or Square. Per-transaction fees vary, and some tools charge a monthly fee for lower processing rates, but you can collect card and ACH payments from day one.

Which invoice generator handles tax calculations best?

QuickBooks Online and Xero automatically calculate sales tax based on location and tax rules, which is a big time-saver. Simpler tools let you add manual tax lines; double-check regional tax support if you file in multiple jurisdictions.

What’s the best invoice generator for a freelancer just starting out?

Start with Zoho Invoice or Wave. Both are zero-cost, give you polished templates and unlimited invoices, and let clients pay online, everything a new freelancer needs without monthly overhead.
