What contractor accounting actually requires
Contractor accounting is more demanding than service-business accounting because the unit of analysis is the job, not the client or the period. A contractor with a dozen concurrent projects needs to know which jobs are profitable, which ones are running over budget, and which ones have unrecorded costs piling up. Generic accounting tools designed for transaction-by-transaction accounting do this badly without explicit project tracking enabled.
The four feature areas that distinguish contractor-suitable accounting tools are job costing (per-project P&L), progress billing (often AIA-style), retainage handling, and 1099 subcontractor tracking. A tool that does all four cleanly is suitable. A tool that does some and not others can usually be patched with integrations or workarounds, but the friction adds up.
When to use generic accounting versus construction-specific
The line is roughly at job complexity and client-facing workflow. For sub-contractors and trades doing discrete work on short timelines (a week of electrical work, a residential plumbing repair, a commercial HVAC install), generic accounting software with project tracking enabled handles the books cleanly. The 1099 workflow is the only contractor-specific feature you really need at this scale.
For prime builders running multi-phase construction with change orders, AIA progress billing, lien waivers, and retainage, construction-specific tools (Buildertrend, CoConstruct, Procore for larger commercial) earn their cost. The difference is not the accounting itself but the workflow around the accounting: client communication, scheduling, change orders, document control. Construction-specific tools handle the workflow and integrate with QuickBooks for the books. Generic tools do not handle the workflow at all.
Candidate tools, ordered by fit for typical contractor businesses
Candidate 1
QuickBooks Online (Plus or Advanced)
QBO Plus $50-150/mo bracket
$50-150/moLast verified April 2026
Best for: Most US contractors with 5-25 concurrent jobs
QuickBooks Online from the Plus tier upward includes project tracking and class accounting, which together give you per-job profit and loss reporting. Combined with QuickBooks Payroll for W2 employees and the standard 1099 workflow for subcontractors, this is the default candidate for most US-based contractors. The integration ecosystem is large; specialised contractor add-ons (Knowify, Hub Planner) extend it where needed.
Strengths
Strong project tracking and class accounting from Plus tier
Best US accountant compatibility for contractor businesses
Tight 1099 workflow
Large integration ecosystem with construction-specific add-ons
Trade-offs
Project tracking depth is decent but not best-in-class for complex multi-phase jobs
Best for: Service-based contractors and consulting businesses
Xero pairs with WorkflowMax (a Xero-owned project management tool) for stronger project profitability tracking than Xero alone. The combination is well-suited to service-based contractor businesses (architects, engineers, IT consultants) where the work is project-based but the deliverable is hours and expertise rather than physical construction. Less commonly used by traditional construction trades.
Strengths
Deeper project profitability than Xero alone
Strong multi-currency for international project work
Clean integration between the two products
Good for service-based contractor businesses
Trade-offs
Two products to manage
WorkflowMax is being sunset by Xero with a successor product, verify status
$150+/mo bracket, premium pricing for construction-specific depth
$150+/moLast verified April 2026
Best for: Custom home builders, remodelers, multi-phase construction projects
Construction-specific platform that handles project management, scheduling, change orders, client communication, and progress billing in one place. Integrates with QuickBooks for the actual accounting. The price reflects the depth and the construction-specific feature set (AIA-style billing, lien waivers, retainage handling) that generic accounting tools do not have. Probably overkill for sub-contractors, essential for prime builders.
Strengths
Industry-specific feature depth
Clean change order and AIA billing workflow
Strong client-facing portal
QuickBooks integration is solid
Trade-offs
Higher cost than generic accounting plus a project tracker
Best for residential construction; commercial-construction needs may need different tools
Two products to manage if integrated with QuickBooks
Best for: Cost-sensitive contractors, smaller operations
If you are already in the Zoho ecosystem, Zoho Books and Zoho Projects integrate cleanly to give you per-project profit tracking and basic job costing. The price point is the most aggressive in this candidate set. The trade-off is that Zoho is less common in the US contractor market than QuickBooks, so accountant familiarity is lower.
Strengths
Aggressive pricing across the stack
Decent project-to-books integration
Strong if already using other Zoho apps
Trade-offs
Smaller US contractor accountant network
Less depth than QuickBooks Plus on advanced project tracking
If you pay any individual subcontractor more than $600 in a year, you have to file a 1099-NEC with the IRS by January 31 and provide a copy to the contractor. The compliance steps are: collect a completed W-9 from each subcontractor before the first payment, track payments through the year, generate the 1099 in January, and either e-file with the IRS or mail paper copies.
The penalties for missing 1099 filings range from $60 per form for being slightly late to $310 per form for intentional disregard. For an active contractor paying twenty subcontractors a year, the maximum penalty exposure is real. Accounting software that handles 1099 tracking cleanly and includes e-filing in the price is worth a small premium over a tool that gates e-filing behind a higher tier.
Job costing in practice
Job costing means tagging every transaction with a job code so you can run per-job profit and loss reports. The minimum information per transaction is: which job, what category (labour, materials, subcontractor, equipment), and the amount. A well-set-up system shows you, at any time, the budget against actual against forecast for each open job.
The two common implementation paths are: native job tracking inside the accounting software (QuickBooks Plus has this from the Plus tier; Xero has projects from the entry tier), or a separate project management tool (WorkflowMax, Knowify) that pushes job-coded entries into the accounting software. The native path is cheaper and simpler. The separate-tool path adds depth (better scheduling, time tracking, client communication) at higher cost.
Progress billing and retainage
Progress billing means invoicing for completed portions of a contract rather than the full amount upfront or at completion. AIA-style progress billing, common in commercial construction, formalises this with the G702 and G703 forms. The G702 is the application for payment showing the total contract value, completed value, and amount being requested this period. The G703 is the schedule of values that breaks the contract down by line.
Retainage is the percentage of each progress billing the client holds back, typically 5 to 10 percent, until project completion. The accounting consequence is that retainage receivable sits in a separate account from regular accounts receivable. Some tools (QuickBooks Plus) handle this with a dedicated retainage workflow. Others require manual journal entries to move amounts between regular AR and retainage receivable. For active general contractors, native retainage handling is a meaningful feature.
When to consider construction-specific software
Three signals usually justify the move to Buildertrend, CoConstruct, or similar:
Multi-phase residential construction with change orders that need client sign-off
Active retainage tracking across more than five concurrent jobs
AIA-style commercial work where the client expects standardised billing forms
For typical sub-contractors and tradespeople below those thresholds, QuickBooks Plus with project tracking enabled is the most common right answer.
Three things mostly. Job costing, which means tracking revenue and expenses against a specific project so you can see whether each job actually made money. Progress billing, often AIA-style for construction, where you bill against completed percentages of the contract rather than full invoices. Retainage, where the client holds back a percentage of each invoice (typically 5 to 10 percent) until the project is complete. Generic accounting software handles the first two acceptably and the third badly.
Do I need construction-specific software like Buildertrend?+
It depends on the complexity of your jobs. For sub-contractors handling discrete trades (electrical, plumbing, HVAC) on shorter timelines, generic accounting plus simple project tracking is enough. For prime builders running multi-phase residential construction with change orders, lien waivers, and AIA billing, construction-specific tools like Buildertrend or CoConstruct handle the workflow much more cleanly and the time saved typically justifies the price.
How do I track 1099 subcontractors as a contractor business?+
Two parts. First, get a W-9 from each subcontractor before their first payment. The W-9 captures their taxpayer ID and tells you whether they are 1099-eligible (most individuals and partnerships) or not (most corporations except attorneys and certain medical providers). Second, your accounting software needs to track payments to each 1099 subcontractor through the year and generate a 1099-NEC in January for any subcontractor paid more than $600. QuickBooks, Xero, and the larger platforms handle this; smaller tools sometimes gate 1099 e-filing behind higher tiers.
What is AIA-style progress billing?+
AIA stands for the American Institute of Architects, which publishes the standard contract forms (G702 and G703) used in commercial construction. The forms structure progress billing by listing the schedule of values (the breakdown of the contract by trade or work category) and tracking percentage complete and amount billed against each line. AIA-formatted invoices are expected by most general contractors and architects on commercial projects. Buildertrend, Procore, and a handful of dedicated construction tools generate them; QuickBooks does not natively but third-party templates exist.
How do I handle retainage in accounting software?+
Retainage is the portion of an invoice the client withholds (typically 5 to 10 percent) until project completion. Properly accounted, it sits in a separate retainage receivable account, distinct from regular accounts receivable, until the client releases it at project completion. QuickBooks Plus handles this with a dedicated retainage workflow. Xero requires a manual journal entry approach that works but is more setup. Wave does not really handle retainage. For active general contractors with multiple jobs in retainage at any time, this single feature can decide the choice of accounting tool.
Should I use job costing for every job or just big ones?+
Use it for every job above a small threshold (say, $5,000 contract value). The friction of starting per-job tracking is small once your accounting tool is set up for it, and the data you get back about which kinds of jobs make money is valuable for pricing decisions. Below the threshold, the overhead of job-level coding outweighs the insight.
