Workiz offers the best free plan for contractors. It includes scheduling, dispatch, invoicing, and a built-in phone system for up to 2 users. For a completely free invoicing tool with no user limits, Wave is the best option.
What "Free" Actually Means
Let us be honest about free software. There are three types:
- Free plans with limits. The tool is free for a small team or basic features. When you grow, you pay. This is the most common model.
- Free trials. You get full access for 7 to 14 days, then you pay or lose access. This is not really "free" long-term, but it lets you test before buying.
- Actually free tools. No limits that matter, no trial period. These are rare in contractor software. Wave (invoicing) and Google Workspace (calendar, docs) are the main ones.
We included all three types on this list. For each tool, we tell you exactly what is free and where the limits kick in.
1. Workiz — Best Free Plan for Contractors
Workiz offers the most generous free plan in the contractor software space. You get scheduling, dispatch, invoicing, a client database, and a built-in phone system. All for free, with up to 2 team members.
The phone system is what sets Workiz apart. Calls come in through the app, get logged automatically, and create new leads. You do not need a separate business phone line or call tracking tool. For a solo contractor, this is a real advantage.
The free plan does have limits. You cannot use advanced automations, custom reports, or some integrations. But for a contractor just getting started, the free plan covers everything you need.
When you will need to upgrade: When you add a third team member or need automated text/email follow-ups. Paid plans start at $65/mo.
2. DripJobs — Best Free CRM for Painters
DripJobs offers a free tier with basic CRM and quoting features. It was built by a painting contractor, so the workflow feels right for residential painters and exterior contractors. See our full PaintScout vs DripJobs comparison for details.
When you will need to upgrade: When you want the automated follow-up sequences that make DripJobs shine. Those are on the paid plan at $99/mo.
3. Jobber — Best Free Trial
Jobber does not have a permanent free plan, but its 14-day trial gives you full access to every feature. This is the best way to test a complete field service tool before committing. No credit card needed.
If you try Jobber and like it, the paid plans start at $39/mo. That is less than most contractors spend on lunch in a week. For a deeper look at how Jobber stacks up, see Jobber vs Housecall Pro.
4. Google Workspace — Free Tools You Already Have
You do not need fancy software to get organized. Google gives you free tools that many successful contractors use:
- Google Calendar for scheduling. Share it with your crew so everyone sees the same schedule.
- Google Sheets for estimating. Build a simple template with material costs and labor rates.
- Google Drive for documents. Store contracts, photos, and permits in one place.
- Google Forms for lead capture. Put a form on your website and leads go straight to a spreadsheet.
This is not as smooth as dedicated contractor software. But it costs nothing and it works. Many contractors run their business on Google tools until they hit $200K to $300K in revenue. At that point, the manual work starts eating into growth.
5. Wave — Free Invoicing
Wave is a free invoicing and accounting tool with no user limits and no trial period. You can send unlimited invoices, scan receipts, and track income and expenses. It is not a field service tool, but it handles the money side of your business for free.
Wave makes money by charging for payment processing (2.9% + $0.60 per credit card transaction) and payroll. The core invoicing and accounting features are genuinely free. Many small contractors use Wave alongside a scheduling tool like Jobber or Workiz.
When to Start Paying for Software
Free tools work when you are small. But at some point, manual work becomes the bottleneck. Here are the signs you need to upgrade:
- You miss follow-ups. If leads are slipping through the cracks because you forgot to call back, you need a CRM.
- Scheduling takes more than 30 minutes a day. When you spend more time on logistics than on jobs, a real scheduling tool pays for itself.
- You cannot tell if you are making money. If you do not know your margin on each job, you need job costing.
- Customers complain about communication. If homeowners do not know when you are coming, automated reminders fix that instantly.
For most contractors, the tipping point is around $200K to $300K in revenue or 3 to 5 employees. At that point, $40 to $100 a month for software saves more than it costs.

Start with Workiz's free plan if you need scheduling and dispatch. Add Wave for invoicing. Use Google Calendar and Sheets for everything else. This gives you a complete business system for $0. When you outgrow it, Jobber at $39/mo is the natural next step.
