Best 8 Invoicing Software in 2026: Top Picks for Freelancers & SMBs

FreshBooks is the best invoicing software for most small service businesses right now. This guide covers eight honest picks, from free invoicing apps to full accounting suites, each tested for how smoothly they create invoices, collect payments, and fit into a real workday.

Quick comparison table

1. FreshBooks

Best for: freelancers and service-based small businesses that want invoicing to feel effortless.

FreshBooks takes care of the boring stuff. You set up recurring invoices once, and it sends them on schedule. It also nudges clients with polite payment reminders, so you never chase manually. The built-in time tracker is what sets it apart: log hours on a project and turn them into an invoice with a single click. No double entry. Snap a photo of a receipt to log the expense on the spot. The iOS and Android apps keep everything in sync, letting you invoice from a coffee shop or a job site without juggling spreadsheets.

2. QuickBooks Online

Best for: growing businesses that need invoicing plus full double-entry accounting.

QuickBooks Online gives you a complete accounting engine, not just an invoice sender. Customize templates with your brand, and those invoices feed directly into inventory tracking, payroll, and tax-ready reports. No manual exports. Automatic payment matching is the highlight here: when a client pays, the transaction pulls from your bank feed and marks the invoice paid. That alone saves hours of reconciliation. There is a learning curve, especially if you’re new to double-entry accounting, but for a business outgrowing standalone invoicing, nothing else packs this much depth.

3. Xero

Best for: small to mid-sized teams that value collaboration with their accountant.

Xero ties your sales workflow together. Convert a quote into an invoice and later into a purchase order with a few clicks. No retyping. Accountants love the unlimited user access with permission controls, so they can log in and clean up the books directly. Built-in support for Stripe and GoCardless is a big plus: you can accept direct debit payments right on the invoice without third-party plugins. The dashboard stays refreshingly clean, and fixed-asset tracking is handled natively, which many invoicing tools skip entirely.

4. Zoho Invoice

Best for: very small businesses that want a fully free, no-time-limit invoicing tool.

Zoho Invoice is genuinely free. No expiry, no watermarks, no invoice limits. You get a solid library of templates, an automated recurring invoice engine, and a client portal where customers can view their history, approve estimates, and pay online. The portal is the highlight: it cuts down back-and-forth emails and lets clients mark estimates as accepted with one click. Desktop apps for Windows and macOS mean you aren’t stuck in a browser, and the mobile version handles on-the-go invoicing. It’s the best free option if you never plan to pay.

5. Wave

Best for: sole proprietors and micro-businesses who need free invoicing and basic bookkeeping.

Wave’s invoicing and accounting are completely free. No monthly charge, and you can send unlimited invoices. Receipt scanning is included, and the only costs come from optional online payment processing (standard card fees). Automatic bank transaction imports make this a winner: link your account and Wave pulls in transactions so you can categorize income and expenses on the fly. It won’t handle inventory or multiple currencies, so it stays intentionally lightweight. For a solo business that wants basic books alongside invoices, it’s hard to beat free.

6. Square Invoices

Best for: businesses already using Square for in-person or online payments.

If you already take payments with Square, adding Square Invoices is a no-brainer. Estimates turn into invoices with a tap, and everything—payment links, card readers, online sales—sits in the same Square dashboard. The big win here is speed: you can access funds instantly using Square’s instant transfer, rather than waiting for a standard settlement. There’s no monthly fee; you pay per transaction only when a customer pays online. The mobile app lets you send an invoice from the counter or on the road.

7. Invoice2go

Best for: contractors and tradespeople who need to send professional invoices from a job site.

Invoice2go is built for the field. It’s mobile-first, with templates that look professional even when you fire off an invoice from your phone between jobs. Snap a photo of a receipt and attach it instantly. The neat trick is attaching job-site photos directly to individual line items, great for showing a client the work behind the charge. The subscription costs money, but it slashes paperwork time. Clients can pay via credit card or PayPal right from the invoice, and the app tracks late payers automatically.

8. Stripe Invoicing

Best for: SaaS businesses and online sellers needing programmatic, white-labelled invoices.

Stripe Invoicing is for teams that want invoices to feel like part of their product. You can send invoices from the Stripe Dashboard or generate them automatically via the API, complete with white-labelled branding and 135+ currencies. The real power sits in the billing engine: smart retries for failed payments, automatic reconciliation with Stripe’s revenue reports, and tight integration with subscription logic. It’s not a turnkey, point-and-click tool. You’ll need some technical comfort. For a SaaS business, that flexibility is the whole point.

How we picked these tools

We tested each tool end-to-end, creating invoices, customizing them, and collecting payments. We evaluated mobile app quality, payment gateway integrations (Stripe, PayPal, and more), and feedback from real users. The lineup spans completely free apps, affordable paid plans, and full-featured accounting suites so you can choose based on your budget and needs. We deliberately skipped tools that are purely accounting platforms with a tacked-on invoicing module. Every pick here delivers strong invoicing software without pushing you toward an upgrade.

Frequently asked questions

Is there completely free invoicing software with no limits?

Yes. Zoho Invoice is completely free with no time limit. You get unlimited invoices, customizable templates, recurring billing, and a client portal where customers can view history, approve estimates, and pay online. Wave also offers unlimited free invoicing and basic accounting, charging standard processing fees only when a client pays by card. Both integrate with payment gateways (Stripe, PayPal) so you can accept credit cards directly on an invoice without a monthly fee.

Which invoicing software syncs best with my accountant?

QuickBooks Online and Xero are the top choices. You can invite your accountant or bookkeeper with their own login, set role-based permissions, and keep audit trails. Collaboration becomes simple. Xero’s unlimited user policy is especially handy if you work with several advisors.

Can I send invoices from my phone?

All the tools on this list let you send invoices from a phone. FreshBooks, Zoho Invoice, Wave, Square Invoices, Invoice2go, QuickBooks Online, and Xero have native iOS and Android apps. Stripe Invoicing uses a mobile-friendly web dashboard and API, so it’s less tap-and-go. Invoice2go and FreshBooks stand out for mobile-first invoicing with photo attachments.

The verdict

FreshBooks is our top pick for fast, clean invoicing with built-in time tracking and effortless client reminders. QuickBooks Online is the runner-up if you need full double-entry accounting. If you’re set on avoiding a monthly fee, Wave and Zoho Invoice both give you capable invoicing at zero cost. Stripe Invoicing is the clear choice for API-driven workflows, and Square Invoices works naturally if you already use Square payments.
