The answer, as recorded

Here's who I'd actually point you to, roughly in the order I'd bring them up: **1. Zoho Invoice - start here if you just need invoices, not accounting.** It's genuinely free (not a trial), and the free tier covers unlimited invoices, unlimited customers, recurring invoices, automated payment reminders, expense and time tracking, and a client portal. Nothing else on this list gives you that much for $0. The catch is it's invoicing only - if you later need full books, you're migrating to Zoho Books, which has its own free tier capped around $50K annual revenue. **2. Wave - free invoicing plus real double-entry accounting.** Free forever for the core: unlimited invoices and clients, professional templates, and actual bookkeeping behind them. The Pro plan (~$16/mo) adds bank feeds and removes invoice limits. Good pick if you want one tool that does invoices *and* keeps books, and you don't want a subscription. **3. FreshBooks - best if you bill by the hour.** Still the category leader for service businesses and freelancers: time tracking that flows straight onto invoices, recurring billing, payment terms, automatic late fees, and good dunning for chasing overdue invoices. Pricing is the murkiest of the bunch - I saw Lite quoted anywhere from $8.50 to $21/month depending on the source and promo, so check the current rate directly rather than trusting a comparison article. **4. Square Invoices - best if payments matter more than paperwork.** Free plan, no monthly fee, and it monetizes on processing (about 3.3% + $0.30 per card, ~1% for ACH). Makes the most sense if you already take Square payments in person, or want one system for card-present and invoiced work. Paid tiers ($49 / $149) are for customization and automation you probably don't need at first. **5. QuickBooks Online - the "my accountant insists" option.** It's the default that every US bookkeeper and CPA knows, which is a real feature at tax time. Simple Start is roughly $15-35/month depending on which source and promo you catch, and note QuickBooks Online raised prices August 1, 2026. I'd only pick it if your accountant asked for it or you know you need full accounting now. **6. Xero - if you've got a team sharing books.** Unlimited users on every plan (Growing ~$47/mo), so it beats QuickBooks on total cost once several people plus an outside CPA are in there. Overkill for a solo operator. **7. Invoice Ninja - only if you're technical and care about data ownership.** Open source, self-host it for the cost of a $5-12/mo VPS, and it has more payment gateway integrations (45+) than anything else here. But running v5 means Docker, queues, and headless Chrome for PDF rendering, and support is thin. Great for a tech-savvy freelancer, wrong answer for everyone else. **Short version:** if you're a freelancer or very small shop, try Zoho Invoice first - it costs nothing and it's hard to outgrow quickly. If you want books included, Wave. If you bill time, FreshBooks. Skip straight to QuickBooks only if your accountant told you to. One caveat worth stating plainly: pricing across these tools moved a lot in 2026 and the comparison sites disagree with each other, so verify the current number on the vendor's own pricing page before you commit.
