Accounting software is the backbone of a profitable sub business. You can't track profitability, manage cash flow, or make smart business decisions without accurate numbers. But choosing the right platform is overwhelming—dozens of options exist, and they range from basic bookkeeping to enterprise-level systems.
This guide compares the best accounting software for subcontractors based on construction-specific features, ease of use, cost, and overall value.
What to Look for in Construction Accounting Software
Not all accounting software is built for construction. Before evaluating specific platforms, understand what features matter:
- Job costing: Track costs and profit by project (essential for subs)
- Multi-level estimates: Submit estimates, manage change orders, track variances
- Certified payroll: Generate prevailing wage payroll reports (if you do federal work)
- Lien waiver management: Track and collect lien waivers
- Progress invoicing: Bill multiple times per project as work progresses
- Retainage tracking: Track held amounts and release dates
- Integration with bank/credit card: Auto-sync transactions (reduces manual entry)
- Mobile access: View estimates and jobs from the field
- Tax planning: Quarterly estimated tax reminders and tax reports
Generic accounting software (Wave, FreshBooks generic edition) does basic invoicing and expense tracking. But it won't track job profitability or generate construction-specific reports. You need construction accounting software.
The Top Platforms Compared
QuickBooks Online Plus (Construction Edition)
$165-$385/monthBest for: Mid-size subs ($500K-$5M revenue) who want traditional accounting software with construction features
Key Features:
- Job costing (track revenue and costs by project)
- Estimate management and change orders
- Progress invoicing (bill multiple times per project)
- Retainage tracking
- Bank integration and auto-categorization
- Multi-user access
- Tax reporting and estimated tax reminders
Pros:
- Industry-standard (accountants know it)
- Powerful reporting
- Many integrations (payroll, lending, CRM)
- Good support (not great, but responsive)
Cons:
- Steep learning curve (not intuitive for first-time users)
- Additional cost for accountant or bookkeeper to set up
- Construction features feel tacked on (not native)
- Mobile app is limited
- No certified payroll (requires add-on or separate tool)
Bottom line: QB Online is the default choice for many construction businesses. If your accountant uses it, it's a safe bet. But it's not specifically built for subs and has a learning curve.
Foundation Software
$200-$500/monthBest for: Subs who want construction-first accounting (electrical, plumbing, concrete, etc.)
Key Features:
- Job costing built from the ground up for construction
- Estimate to invoice workflow (native to the system)
- Equipment tracking and depreciation
- Certified payroll (built-in)
- Prevailing wage compliance tools
- Mobile apps for field crews
- Subcontractor management (pay subs within the system)
Pros:
- Built specifically for construction (not an afterthought)
- Certified payroll reduces compliance risk
- Excellent job costing and project tracking
- Strong mobile functionality
- Good support (construction-focused help team)
Cons:
- Higher learning curve than QuickBooks
- Pricey for small subs
- Less integration with other tools (limited ecosystem)
- Overkill for very small subs (<$200K revenue)
Bottom line: Foundation is the gold standard for construction accounting. If you're serious about tracking construction profitability, this is the best choice. But it's an investment.
Sage Intacct (formerly Intacct)
$250-$500+/monthBest for: Growing subs ($2M-$20M+ revenue) who need enterprise-level accounting
Key Features:
- Powerful job costing and project accounting
- Multiple entity support (if you own multiple subs)
- Advanced reporting and dashboards
- API integrations (connects to almost any tool)
- Multi-user with granular permissions
- Scalable (grows with your business)
Pros:
- Most powerful accounting system available
- Excellent integrations
- Advanced reporting capabilities
- Scales to any size
- Strong security and compliance
Cons:
- Expensive (especially for small subs)
- Steep learning curve (requires training or experienced staff)
- Overkill for subs under $2M revenue
- Setup costs can be $5K-$15K
Bottom line: Sage Intacct is the choice for larger, more sophisticated subs. If you're scaling rapidly or have complex business needs, it's worth the investment. For most mid-market subs, it's overkill.
FreshBooks Construction Accounting
$30-$70/monthBest for: Small subs (<$500K revenue) who want affordable, simple accounting
Key Features:
- Simple invoicing and expense tracking
- Basic job costing
- Estimate creation (not robust)
- Bank integration
- Mobile app
- Very affordable
Pros:
- Very affordable (best for small subs)
- User-friendly and intuitive
- Good support
- Quick setup (start using in hours, not days)
- Modern interface
Cons:
- Limited job costing (not ideal for tracking profitability)
- No estimate-to-invoice workflow
- No certified payroll or prevailing wage tools
- No multi-user (single user or very limited)
- Poor reporting capabilities
Bottom line: FreshBooks is great for invoicing and basic bookkeeping, but it won't give you the job-cost insights you need as a sub. Outgrow it quickly if you're trying to scale.
Wave Accounting
Free (or $15-$25/month for payroll)Best for: Tiny subs (solo operators, under $100K revenue) on a tight budget
Key Features:
- Invoicing
- Expense tracking
- Basic reporting
- Bank integration
- Optional payroll add-on
Pros:
- Free (can't beat the price)
- Very simple to use
- Good for beginners
Cons:
- No job costing (can't track project profitability)
- Minimal reporting
- No estimate-to-invoice workflow
- Limited support
- Not scalable (outgrow immediately)
Bottom line: Wave is fine for basic invoicing and tax prep, but it's not construction accounting. You'll lack profit insights and project management. Upgrade to something better as soon as you can afford it.
My Recommendation by Revenue Size
Under $250K Annual Revenue
Use FreshBooks or Wave to start. Keep it simple while you're getting established. Track your income and expenses, stay on top of invoicing, and don't overthink it. Once you hit $250K, upgrade to real construction accounting.
$250K - $2M Annual Revenue
Use QuickBooks Online Plus or Foundation. QB is the safer choice if you have an accountant. Foundation is better if you want construction-specific features and don't already have an accountant. Both will track job profitability, which is critical at this stage.
$2M - $10M Annual Revenue
Use Foundation or Sage Intacct. Foundation if you want construction-first simplicity. Sage if you need advanced reporting and integrations. Both scale well and provide the insights you need to manage a growing business.
Over $10M Annual Revenue
Use Sage Intacct or consider an ERP.** You need enterprise-level accounting. Sage Intacct is the sweet spot. If you have very complex needs (multiple entities, divisions, cost centers), consider a full ERP like NetSuite or Oracle.
Critical Point
Your accountant or CFO should have strong input on this decision. A mismatch between your accounting software and your accountant's tools creates headaches, delays tax prep, and costs money. Ask your accountant what they recommend before you decide.
Implementation Tips
1. Don't Try to Do It Alone
Setting up construction accounting software is complex. Hire a bookkeeper or accountant with construction experience to:
- Set up the chart of accounts (accounts that match your business structure)
- Create job codes and cost categories
- Configure payroll integration
- Set up bank syncing and categorization rules
Budget $500-$2K for setup. It's worth it to avoid months of messy data.
2. Start with Clean Historical Data
Don't import 5 years of messy historical data. Start fresh with your new system. Import only the current year's data, and only if it's already clean. Going forward, keep your data clean from day one.
3. Use Job Codes Consistently
Create job codes for every project. Force every expense and invoice to be assigned to a job. This is what gives you job profitability data.
Example job codes: "Project 001 - ABC Commercial", "Project 002 - XYZ Residential"
4. Reconcile Monthly
Reconcile your bank account to your software every month. This catches errors early and ensures your data is accurate. If you wait until tax time, you'll have a mess to untangle.
5. Run Monthly Profit Reports
Every month, run a job profitability report. See which projects are profitable and which are losing money. This drives business decisions and helps you avoid unprofitable work in the future.
Pro Tip
If you're using FreshBooks or Wave now but anticipate growth, don't waste time learning all the features. Start planning your migration to construction accounting software now. Set a target revenue level ($300K? $500K?) where you'll upgrade. When you hit it, you'll be ready to move without disrupting your business.
Bottom Line
The best accounting software is the one that matches your size, complexity, and budget. Don't overspend on enterprise software when you're small. Don't underspend and lack profitability insights when you're growing. As you scale, your accounting needs change. Plan for that and be ready to upgrade when the time comes.
The single most important feature is job costing. If your software can't tell you which projects are profitable, it's not suitable for a sub business. Everything else is secondary.
