🔬How We Score Every Tool

Joist was built from the ground up for contractors — not accountants, not freelancers, contractors. You can build a professional estimate, send it for e-signature approval, and convert it to an invoice with a single tap. No spreadsheet juggling, no copy-pasting.

The free plan is genuinely usable. Solo operators doing up to 5 estimates a month will never need to upgrade. And at $29/month for the Pro plan, it’s the most affordable paid tier in this roundup. According to Capterra, Joist holds a 4.5/5 rating from thousands of contractor reviews.

Jobber is the closest thing to a complete operating system for a contractor business. Beyond estimating and invoicing, you get scheduling, dispatching, GPS tracking, client management, automated follow-ups, and a client portal where homeowners can approve quotes and pay invoices without picking up the phone.

Where Joist stops at billing, Jobber keeps going. Automated reminders nudge clients who haven’t responded, and one-click conversions keep your office from drowning in admin work. See our full Jobber review for a deep-dive on every feature.

Buildertrend is what you use when your projects are too complex for a billing app. Designed specifically for residential builders, remodelers, and general contractors, it connects digital takeoffs, bid management, progress billing, change orders, and AIA invoicing into one platform.

At $299/month minimum, it’s not for solo operators. But for mid-size GCs managing multiple projects at once, it pays for itself fast. The Bureau of Labor Statistics projects construction manager employment to grow 8% through 2033 — making robust project management tools increasingly essential.

QuickBooks Online isn’t built specifically for contractors — but its progress invoicing, milestone billing, and customizable templates make it a solid choice for contractors who want to keep their accounting and billing under one roof.

Knowify fills a gap that Jobber and Buildertrend leave open:detailed job costing for trade contractors. It tracks labor, materials, and overhead per job, then generates invoices based on actual project progress — not guesswork. If you’re in HVAC, plumbing, or electrical, also check our guide on plumbing pricing software for trade-specific tools.

Contractor+ packs more into its free plan than any other tool in this roundup — estimates, invoices, job scheduling, client management, and even a basic team feature. It’s not as polished as Joist and lacks the depth of Jobber, but for a solo operator who refuses to pay a monthly fee, it’s the most complete free option available.
