Best Invoicing Software for Contractors

Contractor invoicing isn't sending a simple bill for services rendered. You're dealing with progress billing across project milestones, retainage holdbacks (that 5–10% your client withholds until final completion), change orders that modify the original contract, and sometimes AIA billing forms that general contractors and commercial clients require. A tool built for freelancers or consultants won't cut it. You need invoicing software that understands how construction and contracting projects actually bill. Here's what works in 2026 — from solo tradespeople to mid-size construction firms.

Detailed Reviews

QuickBooks Online Plus — $115/mo

QuickBooks Plus handles contractor invoicing through its project feature. Create a project for each job, set a budget, and issue progress invoices as milestones are completed. Each invoice can pull from your estimate, billing a percentage or dollar amount per line item. The workaround for retainage: create a "Retainage Payable" liability account and manually deduct the holdback percentage from each progress invoice, releasing it on the final bill. It works but requires discipline. Subcontractor tracking and 1099 generation at year-end round out the contractor features. The integration with estimating tools like Buildertrend and JobNimbus adds functionality. Downside: no native AIA billing — you'll need an add-on or manual G702/G703 generation.

Verdict: Best for general contractors who want one tool for invoicing, job costing, and accounting.

Buildertrend — $199–$799/mo

Buildertrend is the all-in-one project management platform for residential builders, and its invoicing module reflects that specialization. AIA billing (G702/G703 forms) generates natively. Change orders link to the original contract and update the billing schedule automatically. The client portal lets homeowners view project progress, approve selections, and pay invoices online. Progress billing tracks percentage-complete per line item. The Essential plan ($199/mo) covers project management and basic financials; Advanced ($499/mo) adds bidding, purchasing, and warranty tracking; Complete ($799/mo) includes everything. The investment is significant, but for builders managing multiple concurrent projects, the centralization saves hours per week.

Verdict: Best for residential builders and remodelers who need AIA billing and full project management.

Invoice Fly — $5–$12/mo

Invoice Fly is built for tradespeople who work in the field and need to invoice from their phone. Create a professional invoice in under 60 seconds, attach photos of completed work, add your logo, and send via text or email. The app supports multiple tax rates, discounts, and payment terms. The Basic plan ($5/mo) covers invoicing and estimates; Pro ($12/mo) adds recurring invoices, time tracking, and expense tracking. It's not a project management tool — there's no job costing, no progress billing, no retainage tracking. But for a solo plumber or electrician who completes 3–5 jobs per week and needs to invoice on-site before heading to the next call, the speed and simplicity are the point.

Verdict: Best for solo tradespeople who invoice from the job site and value speed over features.

FreshBooks — $33–$60/mo

FreshBooks serves independent contractors who bill for time and expertise rather than materials and construction. Start a timer for a client consultation, site visit, or design work; tracked hours populate your invoice automatically. Project-based billing organizes work by client and engagement. Automated reminders nudge clients who haven't paid. The proposals feature lets you send estimates that convert to invoices. Downsides for construction contractors: no progress billing, no retainage, no change order tracking, no AIA forms. This is the tool for IT contractors, consultants, and professional service providers — not builders.

Verdict: Best for independent 1099 contractors billing hourly for professional services.

Jobber — $49–$249/mo

Jobber is purpose-built for home service contractors: landscaping, HVAC, plumbing, cleaning, pest control, roofing. The workflow is create a quote → schedule the job → dispatch the crew → complete → invoice → collect payment. GPS tracking shows where your team is. The client hub lets homeowners approve quotes, pay invoices, and request service. The Core plan ($49/mo) covers quoting, scheduling, and invoicing for 1 user. Connect ($129/mo) adds automation, online booking, and GPS tracking. Grow ($249/mo) adds advanced reporting, two-way texting, and quote follow-ups. For home service businesses, Jobber replaces 3–4 separate tools. The limitation: it's not built for large construction projects with progress billing or AIA requirements.

Verdict: Best for home service contractors who need scheduling + quoting + invoicing in one platform.

CoConstruct — Custom ($99+/mo)

CoConstruct targets custom home builders and remodelers with a depth that general tools can't match. Selection sheets let clients choose finishes, fixtures, and materials with pricing that flows into the budget. Change orders update the contract and billing schedule simultaneously. Progress billing ties to project milestones. The client portal is polished — homeowners track their build daily. The budgeting module shows estimated vs. actual costs per line item in real time. Pricing is custom (typically starting around $99/month for the base tier), and the tool assumes you're managing complex residential construction, not quick-turn service jobs. If you build custom homes, CoConstruct is worth the investment. For everyone else, it's overpowered.

Verdict: Best for custom home builders who need selection management, change orders, and progress billing.

Square Invoices — Free

Square offers free invoicing that handles basic contractor needs: create professional invoices, add milestone-based payment schedules (bill 30% upfront, 40% at framing, 30% at completion), accept online payments (2.9% + $0.30), and send automatic reminders. No monthly fee — you pay only transaction fees when clients pay. The mobile app lets you invoice and collect payment from the job site. For a new contractor building their business, Square is the free starting point. The limitations: no job costing, no retainage, no change orders, no AIA billing. As your business grows, you'll outgrow Square's invoicing.

Verdict: Best for new contractors who need free, professional invoicing with milestone-based billing.
