Should I replace QuickBooks or add a construction tool on top of it?

Smaller subs ($1M–$5M) often do well adding a job costing layer on top of QuickBooks — MarginLock or Knowify work this way. Larger subs ($5M+) with a controller usually benefit from replacing QuickBooks entirely with Foundation or Sage 100.

Is QuickBooks good for construction accounting?

QuickBooks handles general bookkeeping, accounts payable, and basic accounting well — and most contractors already use it. Where it falls short is construction-specific work: it has no WIP schedule, no cost-to-complete projection, no job-level margin report, and retainage tracking requires manual journal entries. For a shop with 3-4 active jobs, those gaps are manageable. Once you're running 10+ jobs simultaneously, manually assembling WIP and job cost reports from QuickBooks data adds 4-8 hours per month and introduces errors that show up at the worst times — bonding renewals, bank draws, and job closeout.

PROS & CONS

MarginLock

Pros

Tracks job costs at the phase and cost-code level
WIP schedule generation without Excel
Retainage and change order tracking

Best fit for specialty trade subs, not GCs or residential

Pricing: $20/month (Core), $49/month (Pro), $99/month (Enterprise)

Verdict: Best option if your core problem with QuickBooks is job costing accuracy and WIP visibility — not replacing QuickBooks accounting entirely.

What QuickBooks Can’t Do for Contractors

QuickBooks is built for general small business accounting. It handles invoicing, expenses, bank reconciliation, and tax reporting well. Most small contractors start with it, and many keep it even after outgrowing it — because switching accounting software is painful.

The problems show up when you have 5+ active jobs running at the same time and you need to know: which jobs are on track, which are running over, what you’ll earn versus what you’ve billed, and how much money you’re holding in retainage.

QuickBooks can’t answer those questions without significant manual work. That’s the gap these tools fill.

What to Look For in a QuickBooks Alternative

Three decisions shape which tool fits:

Replace QuickBooks or layer on top of it? Full replacements (Foundation, Sage 100) handle GL, payroll, AP/AR, and job costing in one system. Layered tools (MarginLock, Knowify) keep QuickBooks for general accounting and add construction-specific features on top. Full replacement is more powerful but costlier and harder to implement.

Sub or GC? Specialty trade subcontractors need cost-code level job costing, WIP schedules, and retainage. General contractors need those plus owner billing, draw schedules, and subcontractor payment management. The tools that serve GCs well often don’t serve subs as well, and vice versa.

Team size and budget? Per-seat pricing (Foundation, Sage 100) becomes expensive fast as your team grows. Flat-rate tools (MarginLock, Buildertrend) have a predictable monthly cost regardless of how many users need access.

Why can't QuickBooks do job costing for contractors?

QuickBooks can track costs by project using class or job tracking. What it can't do: cost-code level tracking (phase by phase), WIP schedule generation, retainage accounting, or cost-to-complete projections. Contractors using QuickBooks for job costing typically supplement with spreadsheets — which means double data entry and numbers that are always a few days out of date.

What does a contractor need that QuickBooks doesn't have?

Four things: (1) retainage — holding back 5-10% until project completion, (2) WIP schedules — tracking overbilled/underbilled status on all active jobs, (3) cost-to-complete — projecting final job margins before the job ends, (4) change order management — tracking cost and revenue changes through a job's life.

Should I replace QuickBooks or add a tool on top of it?

Depends on your revenue and complexity. Smaller subs ($1M-$5M) often do well adding a job costing layer on top of QuickBooks — tools like MarginLock or Knowify take this approach. Larger subs ($5M+) with a controller usually benefit from replacing QuickBooks entirely with a full construction accounting system like Foundation or Sage 100.

How much does switching from QuickBooks to a contractor-specific tool cost?

The software cost depends on the tool. The switching cost includes data migration (your existing job history, chart of accounts, vendor lists), staff training, and the productivity dip during the transition. Most purpose-built tools take 2-8 weeks to get fully operational. Foundation and Sage 100 implementations take 3-6 months.
