Contractor accounting is built around job costing, sub 1099-NEC management, and progress billing. Here's which software handles those needs best for GCs and specialty trades in 2026.
QuickBooks Online Plus is the most common starting point for independent contractors and small specialty trades. QuickBooks Enterprise for Contractors is the step-up for GCs with 4+ active projects. Sage 100 Contractor and Foundation Software are the purpose-built alternatives for larger or more complex operations. The non-negotiables for contractor accounting: job-level cost tracking, subcontractor 1099-NEC management, and the ability to produce a WIP schedule for lenders.

Contractor accounting is a specialized discipline. Job costing (tracking actual vs. budgeted cost by project), subcontractor 1099-NEC compliance, and work-in-progress (WIP) schedule production for lenders and bonding companies are requirements generic accounting software handles poorly by default. Picking the right software — and configuring it correctly at setup — saves significant time and compliance risk downstream.
1. QuickBooks Online Plus — Best for specialty trade contractors and small GCs (1–3 projects)
QuickBooks Online Plus with the Projects feature handles basic job costing, 1099-NEC management, payroll, and bank reconciliation. The CPA ecosystem is the widest available — virtually every contractor-focused CPA knows QBO. For a specialty trade contractor (electrician, plumber, HVAC, framing) with a few active jobs, QBO Plus is the practical starting point.
2. QuickBooks Enterprise for Contractors — Best for GCs with 4+ active projects
Enterprise for Contractors adds job-costing reports, subcontractor management, job status reporting, and certified payroll. It's the standard mid-tier platform for small GCs. Still not a full construction ERP — WIP schedules are available but may require CPA assistance for complex multi-phase projects.
3. Sage 100 Contractor — Best for established GCs needing WIP-native accounting
Sage 100 Contractor is purpose-built for construction. Native WIP reporting, AIA billing, certified payroll, and subcontractor lien-waiver tracking. The trade-off: higher implementation cost and Sage-certified partner requirement for setup. For a GC that regularly provides WIP schedules to lenders or bonding companies, this is the right step-up from QuickBooks.
4. Foundation Software — Purpose-built alternative with strong construction accounting reputation
Foundation Software handles the full construction accounting stack natively: job costing, WIP, AIA billing, payroll, and equipment management. Well-regarded among construction-focused CPAs who work with mid-market contractors.
5. Xero + construction add-on — For contractors who prefer Xero
Xero handles the general accounting layer but lacks native construction features. Paired with a job-costing or project-management add-on, it can work for simple contractors. The construction-specific ecosystem is thinner than QuickBooks. Verify your preferred add-on's Xero compatibility before committing.
Add every sub as a vendor with W-9 information before the first payment. Route all sub payments through that vendor record. Year-end 1099 generation is automatic. The failure mode: paying subs from a personal account or bank transfer and trying to reconstruct the list in January. IRS penalties apply per missing return, and the reconstruction tax (in CPA fees and stress) is avoidable.
Construction lenders require WIP schedules, AR aging reports, and clean P&Ls for most loan types above $50K. Equipment financing lenders review bank statement reconciliation. The contractor with clean books who can produce a WIP on request gets better terms and faster processing than one who can't.

In QuickBooks Online, enable the 'Projects' feature (under Settings > Advanced). Create a Project for each job. Assign time entries, bills, expenses, and labor costs to the relevant project. QBO's Project Profitability report shows revenue, costs, and margin by project. For a contractor with 1–3 active projects, this is adequate. For a GC with complex multi-phase projects or AIA billing requirements, QuickBooks Enterprise for Contractors or Sage 100 Contractor provides more native construction-accounting depth. Your CPA should configure the chart of accounts at setup to ensure project costs roll up to the right Schedule C categories.
Add every subcontractor as a vendor in your accounting software before making any payment. Record their W-9 information (name, address, EIN or SSN, entity type). Route all sub payments through that vendor record. At year-end, your software generates a list of vendors paid $600+ for services — those are your 1099-NEC recipients. IRS penalties apply per missing or incorrect return. Setting up vendor records correctly before the first payment is the only reliable method. After-the-fact reconstruction from bank statements is error-prone and time-consuming.
Progress billing invoices a percentage of the contract amount based on work completed to date (percentage-of-completion method) rather than a fixed schedule or lump sum at completion. AIA G702/G703 is the industry-standard format for commercial construction progress billing. QuickBooks Online does not natively generate AIA G702/G703 invoices — a template or third-party tool is needed. QuickBooks Enterprise for Contractors and Sage 100 Contractor have more native progress-billing support. Your accounting software records the revenue as each progress invoice is issued; the WIP schedule tracks overbilling and underbilling across all active projects.
A Work-in-Progress (WIP) schedule summarizes each active project: contract amount, costs incurred to date, billings to date, and the resulting over/underbilling position. It's required by most construction lenders and bonding companies because it shows whether a contractor is managing project cash flow responsibly or systematically overbilling or underbilling. QuickBooks Enterprise and Sage 100 Contractor generate WIP schedules natively. Generating one from QuickBooks Online Plus requires a CPA to manually assemble it from project reports — possible but more labor-intensive.
Contractor lenders review P&Ls, WIP schedules, AR aging reports, and subcontractor vs. employee mix. Clean books that produce those reports quickly are a material underwriting advantage. Equipment-financing lenders also review bank statement reconciliation and P&L on equipment purchases.
