7 Best Free Estimate Software for Contractors (Actually Free, Not Free-Trial) — 2026

Census Bureau data shows that 47% of construction firms are solo operators or companies with fewer than 5 employees. Most of them don't need — and can't justify — $50 to $300 per month for estimating software. But here's the problem: half the "free estimating software" results on Google are actually 14-day free trials. Once the trial ends, you're paying full price or you lose access to everything you built. This list is different. Every tool below has a permanent free tier — no credit card required, no trial expiration, no bait-and-switch. If it says "free," it stays free.

What "Free" Actually Means in Software

Before we get into the tools, it helps to understand the three types of "free" you'll find when shopping for estimate software. Not all of them mean what you think.

1. Free Forever with Limits

You get a permanent free tier that never expires. The trade-off is a cap on documents per month, number of projects, or certain features. This is how DocJoist, Bookipi, and Methvin work. You can use them indefinitely without paying a cent — you just hit a ceiling at some point.

2. Free Trial That Expires

You get full access for 7 to 14 days, then the software locks you out unless you enter a credit card. Joist and Jobber fall into this category. These are perfectly good tools, but they are not free — they're paid tools with a test drive. None of these made our list.

3. Freemium with Heavy Restrictions

A free tier exists, but core features are locked behind a paywall. You can technically use the tool for free, but the experience is limited enough that most users upgrade quickly. Contractor+ leans toward this model — its free plan is generous on breadth but restricted on depth.

Every tool on this list falls into category 1 or 3. We excluded anything that is purely a free trial. If you want a broader directory of paid and free options, G2's construction estimating software category is a good starting point.

Quick Comparison Table

Here's how all 7 tools stack up across the features that matter most to contractors:

1. DocJoist — Best for Trade-Specific Estimates + Lien Waivers

DocJoist is a free estimate and lien waiver generator built specifically for contractors. Where most free tools give you a blank estimate template and wish you luck, DocJoist ships with pre-built line items for 10 trades — including roofing, painting, plumbing, electrical, HVAC, landscaping, drywall, concrete, kitchen remodel, and general remodeling. You pick your trade, and the estimate pre-populates with the line items you actually use.

The biggest differentiator is lien waivers. DocJoist is the only free estimate tool that also includes a full lien waiver generator — all 50 states, all 4 waiver types, with verbatim statutory language where required. If you're a contractor who regularly sends estimates and signs lien waivers, this is the only tool where you can do both without paying for two separate services.

What You Get Free

• 3 documents per month (estimates or lien waivers)
• Pre-built line items for 10 trades: roofing, painting, landscaping, plumbing, electrical, HVAC, drywall, concrete, kitchen remodel, general remodeling
• Lien waiver generator — all 50 states, all 4 types, verbatim statutory language
• Live PDF preview while editing
• Auto-fill from company profile
• Dashboard for saved documents

What's Behind the Paywall (Pro $19/mo)

• Unlimited documents
• No watermark
• Custom branding
• Full document history (see pricing)

Best for: Contractors who need both estimates AND lien waivers, or who want trade-specific templates instead of starting from scratch.

Limitations: No invoicing (yet). No payment processing. Web app only (no native mobile app). 3-document monthly limit on free tier.

2. Contractor+ — Best All-in-One Free Tool

Contractor+ tries to be the Swiss Army knife of contractor apps. Its free plan includes estimates, invoices, client management, and basic team management — plus a material price database with over 3 million items. If you want one app that handles scheduling, CRM, and estimates (even if each feature is a bit shallow on the free tier), Contractor+ gives you more breadth than any other free tool on this list.

The catch is the freemium model. The free tier unlocks a wide range of features, but many of them are limited in ways that push you toward upgrading. Custom branding, advanced reporting, and API access are all paid. Still, for a contractor who wants a basic all-in-one tool without paying anything, it's hard to beat.

What You Get Free

• Estimates and invoices
• Material price database (3M+ items)
• Client management
• Team management (limited)
• iOS and Android apps

What's Behind the Paywall

• Full scheduling and dispatch
• Custom branding
• Advanced reporting
• API access

Best for: Contractors who want a broader toolset (scheduling, client management) beyond just estimates.

Limitations: Free plan has feature restrictions (not document limits). No lien waiver generation. No trade-specific pre-built templates. Material database pricing may not reflect local costs.

3. Bookipi — Best Unlimited Free Estimates

If your main concern is hitting a document cap, Bookipi solves it. The free plan has no monthly limit on estimates or invoices — you can create as many as you need, forever. With over 750K users, it's one of the most popular free estimate apps on the market.

The interface is clean and simple. You create an estimate, add line items, and send it as a PDF. It works well on both iOS and Android. The trade-off is that Bookipi is a generic invoicing app — it wasn't built for construction. There are no trade-specific templates, no material databases, and no lien waivers. If you just need a clean estimate PDF with no strings attached, Bookipi delivers.

What You Get Free

• Unlimited estimates and invoices — no monthly cap
• 750K+ users
• Clean, simple interface
• iOS and Android apps

What's Behind the Paywall

• Custom branding
• Recurring invoices
• Payment processing

Best for: High-volume contractors who need unlimited free documents and don't need construction-specific features.

Limitations: Not construction-specific — no trade templates, no lien waivers, no material databases. Generic estimate format.

4. SimplySend — Best for Estimates + E-Signatures

SimplySend stands out for one reason: it's 100% free with no paid tier at all. There is no premium plan, no upgrade nag, no feature gating. You get unlimited estimates, unlimited invoices, built-in e-signatures, and online payment acceptance — all without paying anything.

The e-signature feature is the real draw. Most free tools make you export a PDF and get it signed through a separate service. SimplySend bakes client approval directly into the workflow: you send an estimate, the client signs it digitally, and you have a record. For contractors who want a signed estimate before starting work, this eliminates an extra step.

What You Get Free

• Unlimited estimates and invoices
• E-signatures built in
• Online payments
• 100% free (no paid tier exists)

Best for: Contractors who want free estimates with built-in e-signatures for client approval.

Limitations: No construction-specific features. No trade templates. No lien waivers. Limited customization options.

5. STACK — Best for Digital Takeoffs

STACK is the only tool on this list built specifically for digital takeoffs — measuring quantities directly from blueprints and plan sets. If you work from architectural drawings and need to calculate materials from a PDF plan, STACK's free tier gives you cloud-based takeoff tools, a materials database, and training resources to get started.

This is a fundamentally different kind of estimating tool. Where DocJoist or Bookipi help you build and send an estimate document, STACK helps you figure out the quantities that go into that estimate. Many contractors use a takeoff tool like STACK alongside a simpler estimate generator — they're complementary, not competitors.

What You Get Free

• Digital takeoff tools (measure from blueprints)
• Cloud-based estimating
• Materials database
• Training included

What's Behind the Paywall

• Advanced assemblies
• Team collaboration
• Premium integrations

Best for: Contractors who work from blueprints and need digital takeoff capabilities alongside estimating.

Limitations: Overkill for simple residential estimates. Steeper learning curve. Not ideal for the contractor who just needs to send a quick estimate from the job site.

6. Methvin — Best for Job Costing + Estimating

Methvin combines estimating with job costing — tracking your actual costs against what you estimated. Its free tier gives you 5 projects with estimating, budget tracking, reporting, and even multiple user accounts. If you've ever finished a job and wondered whether you actually made money on it, Methvin helps you answer that question.

The estimating-to-job-costing workflow is Methvin's strongest feature. You build an estimate, win the job, then track expenses against each line item as the project progresses. For contractors who want to improve their estimating accuracy over time, this feedback loop is valuable.

What You Get Free

• 5 projects (estimating + job costing + project management)
• Budget tracking and reporting
• Multiple users

What's Behind the Paywall

• Unlimited projects
• Advanced reporting
• Priority support

Best for: Contractors who want estimating AND job costing in one tool (tracking actual costs vs estimates).

Limitations: Based in New Zealand — some features are region-specific. Free tier is project-limited (5 projects, not document-limited). No lien waivers or US-specific construction features.

7. Homewyse — Best for Quick Cost Calculations

Homewyse is not estimating software in the traditional sense — it's a cost calculator. You enter your zip code and project type, and it returns localized material and labor cost breakdowns for over 100 project categories. No account required. Completely free.

Contractors use Homewyse in two ways. First, as a sanity check: before you build a detailed estimate, run the numbers through Homewyse to see if you're in the right ballpark. Second, as a client-facing reference: showing a homeowner third-party cost data can help justify your pricing. It's not a replacement for a real estimating tool, but it's a useful companion.

What You Get Free

• Zip-code-specific cost calculators for 100+ project types
• Material and labor cost breakdowns
• Completely free (no account needed)

Best for: Getting a quick cost sanity check before building a detailed estimate. Also useful for showing clients third-party cost data to justify pricing.

Limitations: NOT full estimating software — it's a cost calculator, not a document generator. You can't create, customize, or send estimates. No lien waivers, no invoicing, no document management.

What About Joist, Jobber, and HousecallPro?

These are the three tools people expect to see on a "free estimate software" list. They're good products — but none of them are free.

Joist no longer has a free plan. It starts at $10/month, and even the cheapest tier limits you to 5 documents per month. The app itself is well-designed, but it doesn't qualify for this list. (See our DocJoist vs Joist comparison for a detailed breakdown.)

Jobber has no free plan. It starts at $49/month. Jobber is a full field service management platform — scheduling, dispatch, CRM, invoicing, and estimates. It's an excellent tool if you run a crew of 5 or more, but it's overkill (and overpriced) if you just need to send estimates.

HousecallPro has no free plan. It starts at $65/month. Similar to Jobber in scope — great for larger operations with multiple technicians, but expensive for solo contractors who just need a way to send professional estimates.

Invoice Simple has a limited free tier but is heavily restricted and more invoice-focused than estimate-focused. ServiceTitan is enterprise pricing ($250+/month) — not relevant for contractors shopping for free tools.

If budget isn't a constraint and you need a full business management platform, Jobber or HousecallPro are solid choices. The SBA's small business guide has good advice on evaluating technology investments. But if you need estimates and waivers and want to stay free, the 7 tools above are your best options.

How to Choose the Right Free Estimate Tool

With 7 genuinely free options, the right choice depends on what you actually need day-to-day. Here's a quick decision framework:

• Need lien waivers + estimates? → DocJoist (only tool that does both)
• Need unlimited free documents? → Bookipi or SimplySend
• Need a full business tool (scheduling, CRM)? → Contractor+
• Need digital takeoff from blueprints? → STACK
• Need job costing alongside estimates? → Methvin
• Just need a quick cost check? → Homewyse

Most solo contractors and small crews will be best served by either DocJoist (if you need trade-specific templates and lien waivers) or Bookipi (if you need high volume with no cap). If you outgrow the free tier, paid plans in this space typically run $10 to $19/month — a fraction of what the big field service platforms charge.

One more thing: you don't have to pick just one tool. Many contractors use Homewyse for cost research, DocJoist or Bookipi for generating the actual estimate document, and a separate invoicing app once the job is done. The best stack is the one that fits your workflow without adding overhead you don't need.
