The 5 Best Free Invoicing Software Options for Contractors in 2026
ProToolHQ earns a commission from qualifying purchases at no extra cost to you.
Introduction
If you’re a plumber, electrician, HVAC tech, roofer, or landscaper trying to get paid faster without paying for another monthly subscription, free invoicing software for contractors can genuinely handle the job — at least until your business outgrows it. This roundup covers five tools with real, permanent free plans (not just free trials that convert to a bill in 14 days): Wave, Zoho Invoice, Square Invoices, Invoice Ninja, and PayPal Invoicing. Each one lets you create and send professional invoices at no cost, though most charge a small processing fee when a customer actually pays you online. We tested what each plan includes, what it limits, and which type of contractor it fits best, so you can pick the right one instead of signing up for five free trials and hoping one sticks.
Quick Comparison Table
| Tool | Key Feature | Starting Price |
|---|---|---|
| Wave | Unlimited invoices, bills, and bookkeeping on a permanently free Starter plan | Free (Pro plan $19/mo) |
| Zoho Invoice | Forever-free plan with unlimited invoicing, expense tracking, and time tracking for up to 5 clients | Free (Premium $9-$15/mo) |
| Square Invoices | Free invoicing with milestone-based payment schedules and automatic reminders | Free (pay-per-transaction fees apply) |
| Invoice Ninja | Free cloud plan for 5 clients, or fully free self-hosted version with no client limit | Free (Pro cloud plans from $18/mo) |
| PayPal Invoicing | No setup or subscription fee to create and send invoices; widely recognized by customers | Free (transaction fees apply on payment) |
Wave
Wave’s Starter plan is permanently free — not a trial — and includes unlimited invoices, estimates, bills, and bookkeeping records. For a contractor who wants to send a professional-looking invoice and track basic income and expenses without paying a monthly fee, Wave covers the essentials. You can customize invoice templates with your logo, set up recurring invoices for repeat customers, and let clients pay online.
The catch is on the payment side. Card payments run 2.9% + 60 cents per transaction (3.4% + 60 cents for Amex) on the free Starter plan. If you want lower card fees and features like automatic bank imports, the Pro plan runs $19/month billed monthly or $190/year billed annually. Wave also offers a separate payroll add-on for contractors and employees starting at $40/month plus $6 per active worker, which generates 1099-NEC forms automatically if you’re paying subcontractors through the platform.
Best for: Solo contractors and small crews who want invoicing and basic bookkeeping in one free tool without juggling two separate apps.
In practice, Wave works well for a plumber or electrician who’s tired of tracking job income in a spreadsheet. You can snap a photo of a receipt from the truck and log it as an expense, then generate an invoice from your phone before you’ve even left the job site. The mobile app isn’t as polished as some paid, trades-specific tools, but it covers the basics — create, send, and track invoice status — without friction. One thing to watch: because Wave bundles invoicing and bookkeeping together, it’s worth spending an hour up front setting up your chart of accounts correctly, since a messy setup here can make tax season more painful later.
Here’s what the free plan actually costs you in practice: on a $1,000 invoice paid by credit card, you’d pay about $29.60 in processing fees, and that’s the only cost — no monthly bill, no setup fee. Compare that to a contractor who bills $8,000-$10,000 a month; at that volume, the Pro plan’s lower card rates can pay for its $19/month fee through savings on fees alone, which is worth running the numbers on once your invoice volume grows past a few thousand dollars a month.
Zoho Invoice
Zoho Invoice offers a genuinely free plan with no time limit, and it includes more than most competitors’ free tiers: unlimited invoicing, expense tracking, time tracking, recurring invoices, and customizable templates, all at $0/month. That makes it a strong option if you also want to track billable hours on a job, not just send an invoice after the fact.
The free plan does come with limits — it caps you at 5 clients, so it’s a better fit for a contractor with a small, steady client base than one juggling dozens of one-off jobs. If you outgrow that, the Premium plan runs $9/organization/month billed annually ($108/year) or $15/month billed monthly, and removes the client cap along with adding more advanced reporting.
Best for: Contractors with a handful of repeat clients — like a landscaper with standing monthly contracts — who want time tracking built into their invoicing.
Where Zoho Invoice pulls ahead of Wave is in automation on repeat work. If you mow the same five lawns every week or service the same HVAC maintenance contracts every quarter, you can set up recurring invoices once and let them fire automatically, with automated payment reminders chasing down anyone who’s late. The 5-client cap sounds restrictive, but for a contractor whose business runs on a short list of steady accounts rather than constant new leads, it’s rarely a problem in year one. Zoho Invoice also connects to the wider Zoho ecosystem (CRM, inventory, and more) if you ever want to expand beyond basic invoicing without switching platforms entirely.
Setup takes about 20-30 minutes: create your account, add your business details and logo, import or manually add your first five clients, and build one invoice template you’ll reuse for every job. Because the free plan doesn’t charge its own processing markup beyond standard payment gateway fees, a contractor billing a handful of recurring clients each month can run entirely on the free tier for years without ever needing to upgrade, as long as the 5-client cap fits how they do business.
Square Invoices
Square Invoices has no monthly subscription fee at all — you only pay when a client actually pays an invoice. That makes it appealing for contractors with unpredictable job volume, since you’re never paying for software you didn’t use that month. The free plan includes milestone-based payment schedules (useful for larger jobs billed in stages), automatic payment reminders, and online payment acceptance.
As of January 2026, Square raised its online and invoice payment rate from 2.9% + 30 cents to 3.3% + 30 cents per transaction, and ACH bank transfers run 1% capped at $5. That’s worth factoring in if you invoice large jobs regularly, since the percentage fee adds up faster on bigger tickets. There’s also an optional Square Invoices Plus subscription with more advanced features for a monthly fee, but the standard free plan covers most basic invoicing needs.
Best for: Contractors who invoice inconsistently month to month and don’t want a fixed subscription cost eating into slow seasons.
Square’s biggest advantage for trades is familiarity — if you already take card payments on a Square reader at the job site, your invoicing and in-person payments live in the same dashboard, so you’re not reconciling two separate systems at tax time. The milestone billing feature is particularly useful for roofers and remodelers who collect a deposit up front, a progress payment mid-job, and a final payment on completion. Just do the math on your typical invoice size before committing — at higher transaction volumes, the percentage-based fee can end up costing more over a year than a flat monthly subscription with lower processing rates would.
On a typical $2,500 roofing deposit invoice, the 3.3% + 30 cent online rate works out to roughly $82.80 in fees — noticeable, but still no worse than what most other free platforms charge, and you’re not paying anything if the client pays by check or cash instead. Square’s real value is consolidation: one login for your point-of-sale reader, your online invoices, and your payment reporting, which saves real time at tax season even if the per-transaction cost isn’t the lowest on this list.
Invoice Ninja
Invoice Ninja stands out because it offers two different free paths. The cloud-hosted free plan includes 5 clients and unlimited invoicing at no cost. But if you’re comfortable with a little more setup, Invoice Ninja is also available as free, source-available software you can self-host on your own server — meaning no client limits and no monthly fee at all beyond whatever your hosting costs. Clients get their own portal to view and pay invoices and manage documents either way.
The self-hosted route isn’t for everyone; it requires you to manage your own server and updates, which is more technical lift than most contractors want to take on. But for a business with more than 5 clients that still wants to stay on a free plan, it’s the only real option on this list. If you’d rather not deal with hosting, the paid cloud plans start at $18/month for 2 users and scale up from there.
Best for: Contractors with more than 5 regular clients who are comfortable with (or have someone who can handle) basic self-hosting, and who want to avoid subscription fees entirely.
Most contractors will stick with the cloud-hosted free plan rather than self-hosting, and that’s a reasonable call — it works out of the box with no server to maintain, and the 5-client limit is often enough for a business still in its first year or two. The self-hosted option really shines for contractors who are also comfortable enough with tech (or know someone who is) to want full control over their data and zero recurring cost no matter how big their client list grows. Invoice Ninja also supports multiple currencies and languages, which is a nice bonus if you do any work near a border or with a diverse customer base.
If you go the self-hosted route, expect to spend a few dollars a month on basic hosting (shared hosting plans start around $5-$10/month) plus an afternoon following Invoice Ninja’s setup documentation. That’s a real cost, just not a software subscription — and it’s still dramatically cheaper than most paid invoicing platforms once your client list grows past a dozen or more accounts, since you’re not paying per-client or per-seat fees no matter how large your business gets.
PayPal Invoicing
PayPal Invoicing costs nothing to set up or use for creating and sending invoices — there’s no subscription fee at all. Since most homeowners and small business clients already have a PayPal account, it’s often the fastest way to get an invoice in front of a customer who’s ready to pay immediately, with no new account setup required on their end.
The trade-off is in the payment fees, which run higher than some competitors: standard PayPal Checkout transactions cost 3.49% + 49 cents in 2026, credit and debit cards processed through PayPal run 2.99% + 49 cents, and Pay by Bank (ACH) is the cheapest option at 1% capped at $25. International payments add another 1.5% on top. If you’re also paying subcontractors, PayPal Payouts charges just 25 cents per domestic payment, which is considerably cheaper than routing subcontractor payments through standard invoicing.
Best for: Contractors who want the fastest possible customer recognition and payment experience, and who don’t mind slightly higher processing fees in exchange for convenience.
PayPal’s real strength for a contractor is speed of payment, not depth of features. It doesn’t have the job-costing, time-tracking, or recurring-invoice automation that Wave or Zoho Invoice offer, so it’s better as a simple, no-frills way to bill a homeowner for a one-off repair than as your primary business system. Because the brand is so widely trusted, it can also reduce the “is this a scam” hesitation some customers feel with invoices from less familiar platforms — useful if you do a lot of first-time residential work where trust matters more than fancy formatting.
On a $500 emergency repair invoice, standard PayPal Checkout fees run about $17.95, while Pay by Bank would cost just $5 capped. Steering repeat customers toward the ACH option, where possible, is the single easiest way to cut your PayPal costs without giving up the convenience that makes it worth using in the first place.
How We Chose These Tools
We only included tools with a free plan that doesn’t expire or automatically convert to a paid subscription — no 14-day trials disguised as “free” software. For each tool, we verified current pricing and feature limits directly from the company’s own pricing page or recent, dated coverage, rather than relying on outdated reviews. We prioritized tools that are genuinely useful for contractors specifically: mobile-friendly invoice creation, straightforward online payment collection, and reasonable limits for a small service business rather than a large enterprise. We deliberately left off tools that market themselves as “free” but actually require a paid plan to send more than a couple of invoices a month, since that’s a trial with extra steps, not a real free option for a working contractor.
Final Recommendation
If you want the most complete free toolkit — invoicing plus basic bookkeeping — start with Wave. If you already track billable hours and have a small, steady client list, Zoho Invoice’s free time-tracking features are hard to beat. Contractors with unpredictable job volume who don’t want any fixed cost should look at Square Invoices or PayPal Invoicing, since both are free until a client actually pays you. And if you’ve outgrown a 5-client limit but still want to avoid a subscription, Invoice Ninja’s self-hosted option is the only genuinely unlimited free path on this list. Whichever you pick, read the payment processing fees closely — that’s where the real cost of “free” invoicing software shows up. None of these five tools charge you to send an invoice; they make their money when your customer pays it, so the software itself will never cost you anything until it’s actually working for you. If you’re still not sure which to pick, start with Wave or Square — both take under 15 minutes to set up and let you send your first invoice the same day, so you can try one out on a real job before deciding whether to switch.

FAQ
Is there truly free invoicing software for contractors, or is it always a trial?
Wave, Zoho Invoice, Square Invoices, Invoice Ninja (cloud or self-hosted), and PayPal Invoicing all offer permanently free plans with no expiration date, though most charge a processing fee when a customer pays an invoice online.
What’s the catch with free invoicing software?
The software itself is free, but you’ll almost always pay a payment processing fee — typically 1% to 3.5% plus a flat fee — when a client pays their invoice online with a card or bank transfer. Free plans may also cap the number of clients or invoices you can manage.
Which free invoicing software is best for a solo contractor just starting out?
Wave is a strong starting point because it combines invoicing with basic bookkeeping at no cost, so you’re not managing two separate free tools while you’re getting your business off the ground.
Can I accept credit card payments on a free invoicing plan?
Yes. All five tools in this roundup let you accept online card payments on their free plans — you just pay a per-transaction processing fee rather than a monthly subscription.
When should a contractor upgrade from a free invoicing plan to a paid one?
Upgrade when you hit a client or feature limit that’s actually slowing you down — for example, Zoho Invoice’s 5-client cap or Invoice Ninja’s cloud client limit — or when a paid plan’s lower processing fees would save you more than the subscription costs based on your monthly invoice volume.
