Comparison Table: 8 Best Invoice Software for Small Business in 2026

Free-tier and niche picks

The 30-second read

If you need full books, it is Xero (unlimited users, $25/mo) or post-hike QuickBooks. If you only invoice, FreshBooks or Wave. Everything below is the detail behind that call.

Our pricing monitoring re-checks every vendor page monthly, so the numbers here reflect the May 1 2026 QuickBooks increase and Xero’s March 2026 US update rather than stale screenshots. We weight three things small businesses actually feel rather than feature-count: the real all-in monthly cost (plan plus payment fees plus per-seat charges), how quickly an invoice converts to cash once sent, and whether your accountant can open the file without a fight. Most “best invoice software” lists ignore the last two, which is why so many readers pick on sticker price and regret it a quarter later when the seat fees or the CPA hand-off bite.

The Invoice Tool Fit Score (BuyerSprint Exclusive)

“Best invoice software” is not a single answer. Score your situation on five factors, rate each 0-2, total them, then read the band below.

How to read your score

0-3: you need a full accounting platform, Xero (unlimited users) or post-hike QuickBooks. 4-6: a focused invoicing tool fits, FreshBooks if you bill time, Bonsai if you want contracts bundled. 7-10: stay free, Wave for manual solo books, Zoho Invoice if you are under 1,000 invoices a year.

Which Invoice Software Fits Your Business?

Match yourself to the closest profile. The tool follows from who you are, not the feature list.

Best for solo freelancers and consultants

FreshBooks ($19/mo) or Bonsai ($21/mo). You need recurring invoicing, time tracking, a client portal, and expense capture. FreshBooks if billing hours is the core; Bonsai if you also want contracts and proposals bundled.

Best for a 5-25 person small business

QuickBooks Online or Xero. You need full A/R, A/P, payroll integration, and tax prep, not just invoicing. Xero wins on unlimited users; QuickBooks wins if your CPA requires it.

Best for a side hustle on zero budget

Wave. The free tier sends unlimited invoices indefinitely (single seat, manual entry). Upgrade only when you hire employees or want automatic bank sync.

Best for local service and retail on Square

Square Invoices. If you already use Square card readers, invoicing is a free bolt-on with payments integrated, though the accounting is light.

Best for an agency billing many clients

FreshBooks (projects plus time tracking) or QuickBooks Online with Projects. Both handle multi-client, multi-project billing without spreadsheets.

Best for Zoho and ecommerce stacks

Zoho Invoice if you live in Zoho CRM/One (free to 1,000 invoices/yr, native). Ecommerce on Shopify: QuickBooks Online (native sync) or Xero with A2X for Amazon.

Top 8 Best Invoice Software for Small Business (Tested)

1. QuickBooks Online, most powerful for 5-25 person teams

Best for: small businesses with multiple employees that need invoicing plus full accounting, payroll, and tax prep in one platform.

QuickBooks pricing (post-May-2026 hike): Simple Start $35/mo, Essentials $70/mo, Plus $110/mo, Advanced $250/mo, with payroll up roughly 20% on top. 30-day free trial.

QuickBooks Online is the dominant US small-business accounting platform, with roughly 80% of US small businesses on paid accounting software using QuickBooks. For invoicing it handles recurring bills, automated reminders, multi-currency, and ACH/card via QuickBooks Payments. The weaknesses in 2026: the UX feels dated next to Xero, per-seat pricing scales expensively, and the May 1 2026 increase pushed every tier up 15-25%. It is still the default if you also need full accounting and your CPA lives in it.

2. Xero, cleanest UX with unlimited users

Best for: growing small businesses that want full accounting plus invoicing with a team of 5+ users at a predictable price.

Xero pricing: Early $25/mo (low monthly invoice cap), Growing $55/mo (unlimited invoices and bills), Established $90/mo (multi-currency, projects, analytics). 30-day free trial.

Xero’s structural advantage for small business is unlimited users on every plan. QuickBooks charges per seat; Xero does not. For a growing team, Xero Growing at $55/mo is often well below the equivalent post-hike QuickBooks plan once you add seats. The UX is also meaningfully cleaner, which matters when non-accountants touch the software. Weakness: the Early plan’s low invoice cap means most real businesses need Growing.

3. FreshBooks, best for freelancers and service businesses

Best for: solo freelancers, consultants, designers, and 1-5 person service businesses who invoice clients for projects and hours.

FreshBooks pricing: Lite $19/mo (5 clients), Plus $33/mo (50 clients), Premium $70/mo (unlimited), Select custom. 30-day free trial.

FreshBooks is built around the service workflow: track project time, convert hours to an invoice, send, get paid via the client portal with ACH or card. It is not full accounting and is not trying to be. Reddit threads in r/freelance and r/smallbusiness consistently name FreshBooks the freelancer default, and that matches what we see in user reviews. Weakness: the 5-client cap on Lite means most serious users need Plus at $33.

4. Wave, best truly-free invoice software

Best for: solo side hustles and freelancers starting out who need unlimited invoices at no monthly cost.

Wave pricing: free core (invoicing plus basic accounting, single seat, manual entry). Payments cost 2.9% + $0.60 per card, pay-as-you-go. Auto bank import is on the paid Pro tier (~$19/mo).

Wave is genuinely free for manual core invoicing, not a trial. For a side hustle doing 20-30 invoices a month it is hard to beat. The 2026 caveat: the free tier is now a single seat with no automatic bank connection, so the honest comparison once you want bank sync is Pro plus payments, not “free”.

5. Zoho Invoice, best free plan for Zoho users

Best for: small businesses already using Zoho CRM or Zoho One who want native invoicing.

Zoho Invoice pricing: free up to 1,000 invoices per year. Beyond that, upgrade to Zoho Books (from $20/mo).

Zoho Invoice’s free tier is legitimately generous: 1,000 invoices a year covers most small businesses outright. If you already run Zoho CRM, Books, or One, it is the obvious pick for native integration. Standalone it is capable, but FreshBooks and Wave edge it on UX.

6. Square Invoices, best for local service and retail

Best for: local businesses on Square card readers who want invoicing with no monthly subscription.

Square Invoices pricing: free to send. Processing 2.9% + $0.30 card-not-present, 2.6% + $0.10 card-present. No monthly fee.

Square Invoices fits the Square payment ecosystem cleanly. If you already use Square POS in person, adding invoicing for the occasional remote client is free. It is not a strong standalone tool (light accounting, limited client management) but a solid Square bolt-on.

7. Bonsai, freelancer all-in-one

Best for: solo freelancers who want invoicing plus contracts, proposals, and a light CRM in one subscription.

Bonsai pricing: Starter $21/mo, Professional $32/mo, Business $66/mo. 14-day free trial.

Bonsai bundles invoicing with contracts, proposals, time tracking, tasks, and a basic CRM, the full freelancer stack in one tool. If you would otherwise pay for FreshBooks plus an e-sign tool plus a CRM separately, Bonsai often consolidates to similar or lower total cost. Weakness: weaker in any single category than a dedicated tool; the integration is the value.

8. Invoice Ninja, open-source budget pick

Best for: technical users comfortable self-hosting who want maximum customization at near-zero cost.

Invoice Ninja pricing: self-hosted is free (your own server). Cloud: Pro $10/mo, Enterprise $14+/mo. 14-day trial.

Invoice Ninja is the open-source option for developers and technical owners: 50+ payment gateways (far more than QuickBooks or Xero), full branding control, and zero subscription if self-hosted. Only worth it if you are comfortable running a server; for non-technical users the $10/mo cloud Pro plan is the easier path.

Invoice Software Decision Tree

If the Fit Score did not settle it, use these rules in order. The first that matches is your answer.

Choose Xero or QuickBooks if you need full accounting

Any business that files real books, runs payroll, or has a CPA needs an accounting platform, not a pure invoicing tool. Xero if you have a team (unlimited users); QuickBooks if your accountant requires it or you run heavy inventory.

Choose FreshBooks or Bonsai if you bill clients for time

Solo or tiny service business, time-based billing, no inventory. FreshBooks for the fastest hours-to-paid flow, Bonsai if you also want contracts and a light CRM in the same subscription.

Choose Wave or Zoho Invoice if cost is the deciding factor

Zero budget and willing to enter data manually: Wave free. Under 1,000 invoices a year, or already on Zoho: Zoho Invoice free. Both assume you do not need full books yet.

Invoice Software Setup Checklist (30 Minutes to First Invoice)

1. Sign up and connect a bank account. Most tools (QuickBooks, Xero, Wave Pro) connect to business checking for automated reconciliation.
2. Add your logo and brand colors. Branded invoices get paid noticeably faster, the single biggest speed lever.
3. Set up payment processing. Enable ACH and card acceptance so clients pay from the invoice itself, which cuts chase time sharply.
4. Create 2-3 templates. One-time project, recurring retainer, hourly. Saves about 10 minutes per invoice afterward.
5. Configure late-payment reminders. Auto-send at 7, 14, and 30 days past due to cut collection calls.
6. Connect your accountant. If you use a CPA, confirm they can access the tool (most prefer QuickBooks or Xero).
7. Send your first real invoice. Test end-to-end: client receives, can pay, you get notified.

Frequently Asked Questions

What is the best invoice software for small business?

For 5-25 person small businesses, Xero and QuickBooks Online are the best picks. Xero wins on UX and unlimited users per plan; QuickBooks dominates US market share and CPA familiarity but raised prices 15-25% in May 2026. For solo freelancers, FreshBooks leads. For zero-budget side hustles, Wave is free for manual core invoicing.

What is the cheapest invoice software?

Wave is free for manual core invoicing (you pay 2.9% + $0.60 per card transaction). Zoho Invoice is free up to 1,000 invoices a year. Invoice Ninja self-hosted is free if you run your own server. The cheapest full-accounting paid option is Xero Early at $25/mo.

Is Wave really free?

Yes, for manual core invoicing and basic accounting. In 2026 the free tier is a single seat with no automatic bank connection. Revenue comes from optional paid add-ons: Wave Payments (per-transaction), the ~$19/mo Pro tier for bank sync, and Wave Payroll. The free core is usable indefinitely for solo operators who enter data by hand.

QuickBooks vs Xero for small business, which is better?

QuickBooks wins on US market share, CPA familiarity, and Shopify integrations. Xero wins on UX, unlimited users (vs QuickBooks per-seat), and multi-currency, and the gap widened after QuickBooks’s May 2026 hike. For the full head-to-head see our QuickBooks vs Xero 2026 comparison.

What is the best invoice software for freelancers?

FreshBooks at $19/mo is the most-cited freelancer pick, built around time tracking, a client portal, and converting hours to invoices. Bonsai at $21/mo bundles invoicing with contracts, proposals, and a CRM. Wave is the zero-cost option for freelancers starting out.

Can I use QuickBooks just for invoicing?

You can, but it is overkill and, after the May 2026 hike, expensive. QuickBooks is full accounting software; if you only need invoicing, FreshBooks at $19/mo or Wave (free) fit better. Reserve QuickBooks for when you genuinely need the full accounting suite.

Does FreshBooks have a free plan?

No, FreshBooks offers only a 30-day free trial, no forever-free tier. The cheapest paid plan is Lite at $19/month, capped at 5 billable clients. For a truly free forever alternative, pick Wave.

How does Square Invoices compare to QuickBooks?

Different tools for different jobs. Square Invoices is a free add-on to the Square payment ecosystem, ideal for local businesses already on Square card readers. QuickBooks is full accounting software where invoicing is one feature. Need full books? QuickBooks. Just need free invoicing with your Square POS? Square.

What is the best invoice software for a 2-person business?

For 2 people, Xero Early at $25/mo (unlimited users) or Wave (free, manual) are the smart picks. Avoid post-hike QuickBooks Simple Start at $35/mo with a 1-user limit, Xero is similar money and includes both users. If you send a high invoice volume, move to Xero Growing at $55.

Can I accept credit card payments on these invoices?

Yes, every tool here accepts cards. Typical processing is 2.9% + $0.30 per card-not-present transaction. QuickBooks, Xero, FreshBooks, and Wave integrate their own processors; Invoice Ninja uniquely supports 50+ gateways. ACH/bank transfer is cheaper (about 1% + $0.25) and worth enabling for B2B invoices over $500.
