Best Free Invoice Software for Contractors in 2026

Full disclosure: We built EasyNest. We've tried to be fair and honest about every tool in this list, including our own strengths and weaknesses.

If you're a contractor, builder, plumber, electrician, or any kind of tradesperson, you need a way to send invoices and get paid. But most invoicing software is built for accountants, not for people who spend their day on a job site.

We tested five free invoicing tools and compared them based on what actually matters to contractors: simplicity, PDF quality, quote-to-invoice workflow, and mobile usability.

What contractors actually need

Before we compare tools, let's be clear about what most contractors need from invoicing software:

• Create a quote, send it, get it approved
• Convert that quote into an invoice
• Generate a professional PDF with company branding and banking details
• Track who's paid and who hasn't
• Do all of this quickly, ideally from a phone

What they generally don't need: expense tracking, payroll, inventory management, recurring invoices, multi-entity accounting, or bank reconciliation. Those features are useful for accountants but they add complexity that gets in the way.

Comparison table

1. EasyNest

Best for: Contractors and tradespeople who want simplicity.

EasyNest was built specifically for builders and small businesses. The workflow is straightforward: add your company details and banking info once, add your customers, create quotes, and download branded PDFs. On Pro, you can convert a quote into an invoice without retyping it.

What we like (yes, we're biased):

• Simplest interface of all five tools
• Quote-to-invoice conversion in one click on Pro
• Banking details and VAT automatically included on every PDF
• Customer name included in document numbers (e.g. INV-0012 (Smith Renovations))
• Revenue dashboard showing paid, outstanding, and overdue amounts on Pro
• 30+ currencies supported
• Free plan available, no credit card required

What's missing (being honest):

• No native mobile app yet (works well in mobile browser)
• No recurring invoices
• No expense tracking
• No time tracking
• Limited to 5 quotes and 5 invoices per month on the free plan

Price: Free plan forever. Pro is R49/month for unlimited quotes, invoices, and customers, plus payment tracking and revenue analytics.

2. Wave

Best for: Freelancers who need free unlimited invoicing and estimates.

Wave's free Starter plan includes unlimited invoices and estimates. It's been around for years and is reliable, though its more advanced automation and branding features sit on the paid plan.

What we like:

• Truly free with unlimited invoices
• Unlimited estimates with quote-to-invoice conversion
• Clean, modern interface
• Expense tracking and basic accounting included

What's missing:

• Free plan does not include custom branding or automatic payment reminders
• Mobile invoicing and estimates are paid-plan features
• Its payments and banking features are most useful in Wave's supported markets

Price: Starter is free. Wave Pro is $19/month; payment processing costs extra.

3. Invoice Ninja

Best for: Tech-savvy users who want maximum customisation.

Invoice Ninja is open source and powerful. It has more features than most contractors will ever use, which is both its strength and weakness. The interface can be overwhelming if you just want to send a quick quote.

What we like:

• Open source with self-hosting option
• Very feature-rich (proposals, recurring invoices, time tracking)
• Extensive customisation
• Good API

What's missing:

• Steep learning curve
• Interface is cluttered for simple use cases
• Free plan is quite limited
• Self-hosting requires technical knowledge
• Not built with trades/construction in mind

Price: Free plan includes 5 clients and unlimited invoices. Ninja Pro is $14/month.

4. Zoho Invoice

Best for: Businesses already using the Zoho ecosystem.

Zoho Invoice is solid and well-designed. It integrates with the rest of Zoho's business suite (CRM, Books, Inventory). If you're already using Zoho, it makes sense. If you're not, there's a learning curve.

What we like:

• Professional templates
• Good automation features
• Time tracking built in
• Client portal where customers can view and pay invoices

What's missing:

• Part of a larger ecosystem that can feel complex
• Overkill for a one-person operation
• Can feel slow on older devices

Price: Zoho Invoice is free, with no paid Zoho Invoice tier.

5. FreshBooks

Best for: Service businesses that need time tracking and project management.

FreshBooks is one of the most popular invoicing tools globally. It's well-designed and easy to use. The biggest downside is there's no real free plan, just a 30-day trial.

What we like:

• Very polished interface
• Excellent time tracking
• Good mobile apps
• Proposals and estimates included
• Client portal

What's missing:

• No free plan (starts from $21/month after trial, depending on region)
• Expensive compared to alternatives
• More features than most contractors need
• Not tailored to construction or trades

Price: 30-day free trial. Lite starts from $21/month, depending on region.
