Most “best invoice software” guides start with feature counts and end with whoever’s affiliate program pays best. This one starts with a different number: the actual 5-year price tag you’ll pay for invoicing. Run a 3-person agency through FreshBooks Plus and you’re spending $1,780 over 5 years. Through QuickBooks Plus it’s $2,100. Through Xero Growing it’s $3,300. Through Easy Invoice‘s lifetime license? $399 — one time, no renewals, ever.
After two weeks testing 23 invoicing tools — every major cloud SaaS platform, every credible self-hosted contender, every free option that actually scales — we built this shortlist around the metrics that actually move a small business’s bottom line. Not slickest UI. Not longest feature checklist. Total cost of ownership, payment turnaround speed, and ownership of the data your business runs on.
Our #1 pick will be controversial: Easy Invoice by MatrixAddons — a WordPress plugin, not a cloud SaaS. It’s free forever on WordPress.org (unlimited invoices, no client cap, no trial countdown — 500+ active installs, v2.3.2 updated this week, tested up to WordPress 7.0), with optional Pro tiers starting at $79/yr or $199 lifetime. Here’s why a self-hosted WordPress plugin out-ranks FreshBooks, Wave, and QuickBooks for most small businesses in 2026, plus the nine other tools that win for specific use cases.
The 10 best invoice software tools (2026)
| Rank | Software | Best for | 5-year cost | Free tier |
|---|---|---|---|---|
| #1a | Easy Invoice (Free) | Best free invoice software overall — unlimited invoices + PayPal + PDFs | $0 forever | ✅ Forever free on WordPress.org |
| #1b | Easy Invoice Pro (our pick) | Best paid overall — lifetime license + 19 addons + 9 gateways | $79/yr or $199–$399 lifetime | Pro upgrades free starter |
| #2 | FreshBooks | Best polished cloud SaaS for service businesses | $1,780 | 30-day trial |
| #3 | Wave | Best free cloud invoicing + bookkeeping | $0–$850 | Forever free |
| #4 | Zoho Invoice | Most generous free SaaS tier | $0 | Forever free, unlimited |
| #5 | QuickBooks Online | Best for full accounting integration | $2,100 | 30-day trial |
| #6 | Xero | Best for teams needing unlimited users | $3,300 | 30-day trial |
| #7 | Invoice Ninja | Best open-source SaaS alternative | $0–$1,080 | Free self-hosted |
| #8 | Bonsai | Best for US freelancers (contracts + tax) | $1,260 | 7-day trial |
| #9 | Square Invoices | Best for mixed in-person + online | $0 + gateway fees | Forever free |
| #10 | Sage Accounting | Best for UK small business + MTD | $1,500 | 30-day trial |
How we ranked the 10 best invoice software in 2026
The “best” invoice software isn’t the one with the most features — it’s the one that maximizes the cash you collect per dollar of cost, with the least friction. Here’s the weighted criteria we scored every tool on:
- 5-year total cost of ownership (heaviest weight) — most SaaS bills hide costs in three places: per-user fees, per-client caps, transaction fees stacked on gateway fees. We calculated the real 5-year price tag for a single-user setup at each tool’s entry tier.
- Honest free tier — some “free” tiers cap at 3 invoices per month. We only counted free if you can actually run a real business on it.
- Data ownership and portability — can you export your data cleanly? Better: can you keep your data in your own database forever, immune to vendor shutdowns or pricing changes?
- Payment gateway coverage — PayPal is table stakes. Stripe plus a regional gateway (Razorpay for India, Paystack for Africa, Mollie for Europe) is what cuts payment turnaround from 14 days to 3.
- Recurring + partial payment support — non-negotiable for retainers, subscriptions, and deposit-then-balance billing.
- Integration depth — WordPress, WooCommerce, QuickBooks, Xero, Zapier. The fewer manual touchpoints, the faster cash collection.
- White-label option — essential for agencies reselling invoicing as part of managed services.
With those seven criteria in mind, here’s our ranked shortlist of the best invoice software in 2026.
#1 Easy Invoice — best invoice software overall (2026)
Easy Invoice by MatrixAddons takes the top spot because it wins on the metric that matters most over the lifetime of a business: total cost vs capability. The free version on WordPress.org gives you unlimited invoices, unlimited quotes, 10 professional templates, PayPal payments, a complete client database, PDF generation, and 150+ currencies — with no trial countdown, no client cap, and no upsell nag. Pro extends with 19 modular addons across three tiers and 9 payment gateways. The lifetime license is $199 (single site) or $399 (unlimited sites) — and that’s it forever.
That last number is the headline. FreshBooks Plus is $356 per year. QuickBooks Online Simple Start is $420 per year. Xero Growing is $660 per year. Over 5 years those bills compound to $1,780 / $2,100 / $3,300. Easy Invoice Lifetime at $199–$399 — total, forever — represents 85–95% savings without losing core invoicing capability. For a 3-person agency on the Agency tier ($399 lifetime, unlimited sites), the payback against FreshBooks Plus is under 4 months. Every month after is pure margin.
The honest caveat, up front: you need to run WordPress. If you don’t already, you’ll spin one up on a $5/month host (Hostinger, SiteGround, Cloudways are the cheapest viable options). That puts year-1 cost at roughly $260 ($199 lifetime + $60 hosting), then $60/year forever. Still dramatically cheaper than any SaaS option on this list.
What’s in the free version (the full list)
The free version on WordPress.org is the real product, not a teaser. Here’s everything you get at $0:
- Unlimited invoices & quotes — no client caps, no monthly limits, no trial period
- Professional PDF generation — branded, downloadable, printable invoices and quotes with your logo
- PayPal payment gateway — accept PayPal payments directly via a “Pay Now” button on every invoice
- Custom Payment Links — add an external “Pay Now” link for any other payment provider
- Client management — unlimited client records with full contact details and per-client invoice history
- Quote-to-invoice conversion — one-click convert an accepted quote into an invoice
- Invoice cloning — duplicate any past invoice as the basis for a new one (huge for retainers)
- Auto-incrementing invoice numbers with custom prefixes (e.g., INV-2026-001) — required for proper bookkeeping
- Tax & discount calculations — flexible before/after-tax rules, multiple tax types, per-line-item rates
- 10 professional invoice and quote templates — modern, classic, minimal, corporate styles
- Custom branding — invoice ID prefix, custom terms & conditions, custom footer text
- Customizable email templates — invoice emails, quote emails, payment receipts — all editable
- 150+ currencies + multi-language ready — international clients work out of the box
- Print invoices & quotes — print or save to PDF directly from your browser
- Works with any WordPress theme — Astra, Kadence, Divi, GeneratePress, Blocksy, page builders
- Translation ready — fully internationalised for any language
- Free forever on WordPress.org — v2.3.2, updated this week, 500+ active installs, tested up to WordPress 7.0, GPLv2 licensed
That free-tier list is unusually complete for the category. Wave’s free plan caps you on bank imports. Zoho Invoice’s is fully free but adds a “Powered by Zoho” footer on emails. Square Invoices is free only if you accept Square’s 2.9% gateway. Easy Invoice gives you the full invoicing engine, no caps, no upsell footers, no payment-processor lock-in — and the whole thing runs inside your own WordPress site, so your data lives in your own database forever.
Translation: for the 80%+ of small businesses and freelancers who only need core invoicing, the free WordPress.org version of Easy Invoice is genuinely free and complete — you may never need to pay anything. Pro becomes worth it when you need Stripe (or any non-PayPal gateway), recurring billing, automated reminders, a client portal, time tracking, or accounting sync.
Easy Invoice Pro — 19 addons across 3 tiers
Pro turns Easy Invoice into a complete billing operation. The Personal tier (free with Pro) unlocks 12 addons; Professional adds 3 more; Agency adds 4 more. The addon architecture means you toggle on only what you need — disabled addons add zero PHP, zero queries, zero hooks, so a stripped install runs as fast as the free plugin.
| Plan | Yearly (sale) | Lifetime | Sites | What unlocks |
|---|---|---|---|---|
| Personal | $99 → $79/yr | $199 one-time | 1 | 9 payment gateways + 12 Personal-tier addons |
| Professional | $199 → $159/yr | — | 5 | + Time Tracking, Expense Tracking, Smart Reminders |
| Agency | $299 → $239/yr | $399 one-time (unlimited sites) | Unlimited | + White-Label, Team Roles, Webhooks, Accounting Sync |
- Personal tier (12 addons — free with Pro): Recurring Invoices & Subscriptions, Partial Payments & Deposits, Client Portal, PDF Toolkit (PAID/OVERDUE watermarks), Bulk Email & Export (CSV/PDF/Excel), Item Library, Custom Invoice & Quote Templates (drag-drop builder), Additional Tax Lines (multi-tax per invoice), Email Enhancements (Reply-To, CC/BCC), Secure Signed Links (unguessable URLs), Privacy & GDPR Tools, Reports & Analytics.
- Professional tier (+3 addons): Time Tracking & Project Billing (start/stop timer with one-click invoice conversion), Expense Tracking & Reimbursables (logged receipts with markup), Smart Reminders & Late Fees (multi-step automated chase — recovers 30%+ of overdue invoices).
- Agency tier (+4 addons): White-Label & Brand Override (every label, footer, PDF rebranded), Team Roles & Audit Log (Manager / Accountant / Sales / Viewer roles), Webhooks & Zapier Bridge (HMAC-signed events to any URL), Accounting Sync (two-way QuickBooks Online / Xero / FreshBooks).
9 payment gateways in Pro
Wider regional coverage than FreshBooks, Wave or QuickBooks: Stripe (cards + Apple Pay + Google Pay), PayPal, Square, Authorize.Net, Mollie (Europe: iDEAL, Bancontact, SEPA), Paystack (Africa: cards + mobile money for Nigeria, Kenya, South Africa), Moneris (Canada), Razorpay (India: UPI, netbanking, wallets), and Bank Transfer. Critical for international freelancers and agencies billing in multiple currencies — most SaaS competitors lock you into 1–2 gateways.
Where Easy Invoice wins (the seven criteria scored)
- ✅ 5-year cost: $199–$399 vs $1,780–$3,300 for cloud SaaS. Lowest TCO by a wide margin.
- ✅ Free tier: genuinely free — unlimited invoices, no client cap, no trial
- ✅ Data ownership: your invoices, payments and client database live in your own WordPress database, not a vendor’s cloud. Vendor lock-in is structurally impossible.
- ✅ Payment gateways: 9 covering 6 continents — widest coverage in the category
- ✅ Recurring + partial: both included in Personal tier (free with Pro)
- ✅ Integrations: WordPress + WooCommerce native; two-way QuickBooks / Xero / FreshBooks sync (Agency)
- ✅ White-label: full Agency-tier rebrand (every label, menu, footer, PDF) — cheapest white-label invoicing on the market
Where Easy Invoice falls short (honest cons)
- ⚠️ Requires WordPress. If you don’t already run a WP site, you’ll spend ~$60/year on hosting. Trivial cost but worth knowing.
- ⚠️ No native mobile app. The WordPress admin works fine on mobile browsers, but isn’t as polished as FreshBooks’ iOS/Android apps for invoicing from a phone.
- ⚠️ You manage the hosting. Managed WordPress hosts (Hostinger, SiteGround, Cloudways) make this near-zero work, but it’s still your responsibility.
Best for: any small business, freelancer, consultant or agency already running (or willing to start) a WordPress site. Particularly compelling if you’re billing 50+ invoices a month — the savings vs FreshBooks Plus or QuickBooks Plus pay for the lifetime license inside 4 months. Skip if: you don’t run WordPress and refuse to (jump to FreshBooks or Wave) or you bill primarily through a phone-first mobile app (FreshBooks wins there).
#2 FreshBooks — best polished cloud SaaS for service businesses
FreshBooks is the SaaS the industry recommends most for consultants, agencies, and service businesses that don’t want to run WordPress. Built around time-tracking, project billing, and recurring invoices, it has the polish, the brand recognition, and the integration ecosystem to match. If Easy Invoice is the lowest-cost path to a complete invoicing operation, FreshBooks is the most frictionless out-of-the-box cloud experience.
FreshBooks pricing (2026)
- Lite — $19/mo (or $17.10/mo annual) — up to 5 billable clients
- Plus — $38/mo (or $29.70/mo annual) — up to 50 billable clients
- Premium — $65/mo (or $54/mo annual) — unlimited billable clients
- Select — custom pricing, typically $300–$500+/mo
Watch the add-ons: team members cost an extra $11/user/mo, Advanced Payments (recurring + in-person cards) adds $20/mo, Payroll runs $40/mo + $6/user. A three-person team on the Plus plan with Payroll lands at roughly $156/mo — $1,872/year, $9,360 over 5 years.
Best for: service businesses with under 50 active clients who don’t run WordPress and want a polished cloud UI plus strong recurring billing. Skip if: you already run WordPress (Easy Invoice gives you 90% of FreshBooks at 5% of the 5-year cost) or your volume is low enough to use Wave or Zoho Invoice for free.
#3 Wave — best free cloud invoicing + bookkeeping
Wave is the most-installed free invoicing-plus-accounting platform on the market. The free Starter plan gives you unlimited invoices, unlimited estimates, unlimited bookkeeping, no time limit, no credit card required. It’s the SaaS default for sole proprietors and very small businesses who want a polished cloud tool at zero cost.
- Starter — Free — unlimited invoices, estimates, bills, basic bookkeeping
- Pro — $16/mo annual or $19/mo monthly — adds bank transaction imports, receipt scanning, multi-user
- Payment processing — 2.9% + $0.60 per credit card; 1% for ACH (Wave is the gateway)
Best for: sole proprietors and very small businesses with low invoice volume who want a free, polished cloud tool with integrated basic bookkeeping. Skip if: you need multi-gateway payment support (Wave only processes payments through its own gateway at 2.9% + $0.60) or you want data ownership.
#4 Zoho Invoice — most generous free SaaS tier
Zoho Invoice made the unusual call to make its entire invoicing product permanently free for small businesses — and the free tier is the most feature-rich on the market. Unlimited invoices, unlimited customers, recurring invoices, automated reminders, expense tracking, time tracking, customer portal. The catch: online payments require linking an external gateway (Stripe, Razorpay, 2Checkout) and you pay the gateway’s standard rate.
- ✅ Forever free — unlimited invoices + customers + recurring + reminders + time tracking + portal
- ✅ Tight integration with the rest of Zoho (CRM, Books, Projects) if you use the suite
- ⚠️ “Powered by Zoho” footer on invoice emails in the free plan
- ⚠️ The free version is technically a customer-acquisition tool for Zoho Books and Zoho One — expect upsell prompts
- ⚠️ Cloud-only — no self-hosted or lifetime option
Best for: small businesses and freelancers who want the most feature-rich free SaaS invoicing tool and don’t mind being a soft lead for Zoho’s broader suite.
#5 QuickBooks Online — best for full accounting integration
QuickBooks Online is the industry-standard small-business accounting platform — and its built-in invoicing is more than capable for most service businesses. If you already use QuickBooks (or your accountant insists), there’s almost no reason to bolt on a separate invoicing tool.
- Simple Start — $35/mo
- Essentials — $65/mo
- Plus — $99/mo
- Advanced — $235/mo
Even the entry tier is $420/year. If invoicing is your primary use case, Wave or Zoho Invoice cover it for $0 and Easy Invoice covers it for $79/yr or $199 lifetime. QuickBooks shines when you need GAAP-compliant books, multi-account reconciliation, and CPA-friendly reports beyond what dedicated invoicing tools offer.
#6 Xero — best for teams needing unlimited users
Xero is QuickBooks’ biggest international challenger and the favorite of small-to-mid-sized businesses worldwide. Its defining feature: unlimited users on every plan. A five-person business pays the same Xero subscription as a sole proprietor — a major advantage over FreshBooks ($11/user/mo extra) or QuickBooks Advanced ($235/mo).
- Early — $25/mo — capped at 20 invoices + 5 bills (brutal)
- Growing — $55/mo — unlimited invoices + bills (real entry point)
- Established — $90/mo — multi-currency, project tracking, expenses, analytics
Best for: growing teams of 3+ who want full accounting + invoicing with no per-user fees. Skip if: you only need invoicing — pay $0 for Wave/Zoho or $199 once for Easy Invoice.
#7 Invoice Ninja — best open-source SaaS alternative
Invoice Ninja is the leading open-source SaaS-style invoicing platform — and the closest direct comparison to Easy Invoice for self-hosters who don’t run WordPress. The self-hosted version is forever free if you can manage a $5/month VPS; the cloud Pro tier starts at $18/month after a 2026 price increase.
- Self-hosted — Free (you host on your own VPS)
- Cloud Free — up to 20 clients with limited features
- Cloud Pro — $18/mo annual
- Cloud Enterprise — $30/mo annual
Self-hosted setup requires PHP / MySQL / nginx config — non-trivial for non-developers. The UI feels dated compared to FreshBooks, Wave or Easy Invoice’s WordPress-native admin. Best for: developers and tech-savvy small businesses who want full self-hosted control without WordPress. If you already run WordPress, Easy Invoice delivers the same data ownership with a fraction of the setup work.
#8 Bonsai — best for US freelancers (contracts + tax bundled)
Bonsai bundles invoicing with proposals, contracts, time tracking, and US quarterly tax estimates in a single platform. It’s the right pick if you’re a US freelancer who needs Xero-level invoicing plus contracts and tax automation without paying for three separate tools.
- Starter — $21/mo
- Professional — $32/mo
- Business — $52/mo
Best for: US-based freelancers (writers, designers, consultants, developers) who want one tool for proposals → contracts → invoices → tax estimates. Skip if: you’re not US-based (tax features only apply to US filers) or you already have a contract template you trust.
#9 Square Invoices — best for mixed in-person + online
Square Invoices is free to send and free to track — Square only charges when you accept payment (2.9% + $0.30 for online cards, 2.6% + $0.10 for in-person). For businesses that already use a Square card reader at the point of sale, adding online invoicing is a no-brainer because all transactions land in one Square dashboard.
- ✅ Free to send and track unlimited invoices
- ✅ One dashboard for in-person + online payments
- ✅ Recurring invoices included free
- ⚠️ You’re locked into Square as your payment processor
- ⚠️ Limited template customization vs FreshBooks or Easy Invoice
Best for: restaurants, retail, salons, contractors, and any business taking both in-person and online payments that wants them in one dashboard.
#10 Sage Accounting — best for UK small business + MTD compliance
Sage Accounting (formerly Sage One) is the UK’s most-installed small-business accounting tool, with strong invoicing baked in. Pricing is competitive against Xero, particularly for single-user UK operators. Outside the UK the value weakens — Xero or QuickBooks tend to win on integration depth.
- Accounting Start — $15/mo — invoicing + bank reconciliation
- Accounting — $25/mo — adds cash flow, quotes, multi-user
Best for: UK-based sole proprietors and small businesses who want MTD (Making Tax Digital) compliance built in. Skip if: you’re not in the UK — Xero is generally stronger internationally at similar pricing.
5-year cost comparison (the real numbers)
The big number that gets lost in monthly pricing is what you actually pay over the lifetime of your business. Here’s what each tool costs in years 1, 3, and 5 for a single-user setup at the entry tier (excluding gateway fees, which apply across all options).
| Software | Year 1 | Year 3 | Year 5 |
|---|---|---|---|
| Easy Invoice Free (WordPress.org) | $0 | $0 | $0 |
| Easy Invoice Lifetime (1 site) | $199 | $199 | $199 |
| Easy Invoice Lifetime (unlimited sites) | $399 | $399 | $399 |
| Easy Invoice Personal (yearly) | $79 | $237 | $395 |
| Wave Free / Zoho Invoice Free / Square Invoices | $0 | $0 | $0 (+ gateway fees) |
| Wave Pro (annual) | $170 | $510 | $850 |
| Invoice Ninja Cloud Pro | $216 | $648 | $1,080 |
| Bonsai Starter | $252 | $756 | $1,260 |
| FreshBooks Plus (annual) | $356 | $1,068 | $1,780 |
| QuickBooks Online Simple Start | $420 | $1,260 | $2,100 |
| Xero Growing | $660 | $1,980 | $3,300 |
The math against SaaS competitors gets brutal over a multi-year horizon. A 5-year-old business that started on FreshBooks Plus has spent $1,780 on invoicing alone. The same business on Easy Invoice Lifetime has spent $199. That’s $1,581 redirected into payroll, marketing, or savings — with the same core invoicing capability.

Frequently asked questions
What is the best invoice software in 2026?
Easy Invoice is the best invoice software in 2026 overall — it wins on 5-year total cost of ownership ($199 lifetime vs $1,780–$3,300 for cloud SaaS), data ownership (your data lives in your own WordPress database forever), and feature breadth (19 modular Pro addons + 9 payment gateways). The honest caveat: you need to run WordPress. If you don’t and refuse to, FreshBooks wins for polished cloud SaaS or Wave / Zoho Invoice for free.
What is the best free invoice software?
Easy Invoice is our pick for the best free invoice software in 2026. Free on WordPress.org with no client cap, no trial, no upsell footer: unlimited invoices and quotes, PDF generation, PayPal gateway, client management, custom payment links, 10 professional templates, tax/discount calculations, 150+ currencies, translation ready (v2.3.2, 500+ active installs, tested up to WordPress 7.0). For pure cloud (no WordPress), Wave (free, hosted, with bookkeeping) or Zoho Invoice (most feature-rich free SaaS with recurring + portal + time tracking) are the closest alternatives.
Is invoice software worth it over a free template?
Yes — once you cross ~5 invoices per month. Free templates work for occasional one-offs, but real invoice software adds: payment processing (so clients can pay you directly from the invoice), automated payment reminders (Smart Reminders alone recover 30%+ of overdue invoices), recurring billing for retainers, sales reporting, and a client database that grows with your business. The time saved per invoice typically pays for the software within the first month.
Can I run invoice software on my own WordPress site?
Yes — Easy Invoice is the most powerful invoicing plugin for WordPress in 2026. The free version on WordPress.org includes unlimited invoices, unlimited quotes, PDF generation, PayPal gateway, client database, and 10 professional templates. Pro adds 9 payment gateways (Stripe, Square, Authorize.Net, Mollie, Paystack, Moneris, Razorpay), recurring billing, client portal, time tracking, white-label, and two-way sync with QuickBooks, Xero or FreshBooks. See our deeper WordPress invoice plugin comparison for plugin alternatives.
What about payment processing fees?
Payment processing fees are charged by the gateway (Stripe, PayPal, Square, Razorpay), not the invoicing software. Standard 2026 rates: 2.9% + $0.30 (Stripe / PayPal cards), 2.6% + $0.10 (Square in-person), 1% (Wave ACH). Easy Invoice, Zoho Invoice, and Invoice Ninja don’t take any commission on top of the gateway — your customer pays your gateway account directly. Wave and Square take their cut as the gateway. FreshBooks Advanced Payments adds $20/mo to enable in-person card readers.
Can I send recurring or subscription invoices?
Yes, on most tools — but the entry points differ. Free options: Zoho Invoice (free recurring) and Square Invoices (free recurring with Square gateway). Paid SaaS: FreshBooks, QuickBooks Online, Xero all include recurring on their standard plans. Self-hosted: Easy Invoice Pro Personal tier unlocks the Recurring Invoices & Subscriptions addon (auto-bill weekly, monthly, or any custom schedule).
Which invoice software supports the most payment gateways?
Easy Invoice Pro leads with 9 gateways covering 6 continents: Stripe (cards + Apple Pay + Google Pay), PayPal, Square, Authorize.Net, Mollie (Europe), Paystack (Africa), Moneris (Canada), Razorpay (India), and Bank Transfer. Invoice Ninja supports 40+ gateways via Omnipay but requires self-hosted setup. FreshBooks, Wave, and Square are limited to 1–2 gateways each. For international freelancers and agencies billing in multiple currencies, gateway breadth is often the deciding factor.
Can I white-label invoice software for clients?
Yes — but only on specific plans. Easy Invoice Agency tier ($239/yr or $399 lifetime unlimited sites) includes White-Label & Brand Override that rebrands every label, menu, footer, and PDF. Invoice Ninja self-hosted can be customized via code. SaaS options (FreshBooks, QuickBooks, Wave, Zoho) generally don’t allow full white-label without enterprise contracts. For agencies reselling invoicing as a managed service, Easy Invoice Agency is by far the lowest-cost path.
Is my data safe if the invoicing company goes out of business?
This is the underrated risk of SaaS invoicing. If FreshBooks, Wave, or Zoho shut down tomorrow, you’d have 30–60 days to export your data before access disappears. Two options fully sidestep this risk: Easy Invoice (your data lives in your own WordPress database forever — even if MatrixAddons shut down, your plugin keeps running) and Invoice Ninja self-hosted (you control the database). For mission-critical billing data, self-hosted licensing is the structurally safer long-term bet.
Can I switch invoice software without losing data?
Mostly yes — every tool in this list supports CSV export of invoices, customers, and payments. SaaS-to-SaaS migrations (FreshBooks → Wave, QuickBooks → Xero) use native importers. Migrating to or from Easy Invoice requires WordPress import/export tools and a brief CSV mapping step. Plan a weekend if you have 100+ historical invoices; budget less if you’re starting fresh.
Final verdict: which invoice software wins in 2026?
The honest answer depends on what you’re already running, but the math is consistent: Easy Invoice wins on every long-horizon metric that matters. Lowest 5-year cost (by an order of magnitude). Genuinely free starter. 9 payment gateways. 19 modular Pro addons. White-label option at the lowest price in the category. Your data lives in your own database forever, immune to vendor lock-in. The lifetime license at $199 (or $399 unlimited sites) is the rare case where self-hosted truly beats SaaS on both cost and capability.
The single requirement: you run WordPress. If you don’t already, the entry cost is $60/year of hosting (Hostinger, SiteGround, or Cloudways all start under $5/mo). For 80% of small businesses, freelancers, consultants, and agencies, that’s a trivial tradeoff for what is structurally the lowest-cost path to a complete invoicing operation.
If you absolutely won’t run WordPress, FreshBooks is the safe polished cloud pick at $356/year, or Wave / Zoho Invoice for $0. For the rest of you: install Easy Invoice free from WordPress.org this afternoon and see why ~95% cost savings doesn’t have to mean a 95% feature gap.
