TLDR
MarginLock is the best job costing software for mid-size electrical contractors: $99-$499/month flat rate with unlimited users, real-time cost tracking, and AIA billing. Foundation Software is the incumbent but charges per seat and takes months to implement. Avoid QuickBooks for job costing: it tracks expenses but cannot compare them to a bid in real time.
| Software | Monthly Cost | User Pricing | Real-Time Job Costing | AIA Billing |
|---|---|---|---|---|
| MarginLock | $99-$499/mo | Unlimited | Yes | Yes |
| Foundation | Per seat | Per seat | Yes | Yes |
| Sage 100 | $400+/mo effective | Per license | Yes | Yes |
| Buildertrend | $99-$899/mo | Per user (higher tiers) | Limited | No |
| QuickBooks | $35-$235/mo | Per user | No | No |
MarginLock
Real-time job costing built for specialty trade subcontractors. Flat-rate pricing, unlimited users.
PROS & CONS
MarginLock
Pros
- $99-$499/month flat rate, unlimited users
- Real-time cost-to-complete tracking
- AIA G702/G703 billing
- Mobile time entry by cost code
Cons
- Newer platform
- No payroll integration yet
- No estimating module
Pricing: $99/month (Core) / $249/month (Pro) / $499/month (Enterprise)
Verdict: Best value for $3M-$8M electrical shops that need real-time job costing without Foundation's per-seat pricing.
Foundation Software
Legacy construction accounting incumbent. Deep feature set, dated interface.
PROS & CONS
Foundation Software
Pros
- Deep job costing capabilities
- AIA billing
- Industry standard for decades
- Comprehensive reporting
Cons
- Per-seat pricing adds up fast
- Windows 95-era interface
- Long implementation timeline
- Consultant-dependent setup
Pricing: Per-seat pricing (contact for quote, typically $5,000+ first year)
Verdict: The standard for large contractors, but overkill and overpriced for a $3M-$8M electrical shop with 3-5 office users.
Sage 100 Contractor
Mid-market construction accounting. Capable but complex.
PROS & CONS
Sage 100 Contractor
Pros
- Strong job costing
- AIA billing
- Equipment tracking
- Decent reporting
Cons
- On-premise installation
- Annual license fees
- Complex setup
- Aging interface
Pricing: $5,000-$15,000+ initial license + annual maintenance
Verdict: Capable software stuck in an on-premise model. The upfront cost and ongoing maintenance fees are hard to justify for a shop under $10M.
Buildertrend
Project management platform with some job costing. Better for GCs than subs.
PROS & CONS
Buildertrend
Pros
- Good project management
- Customer-facing portal
- Modern interface
- Change order tracking
Cons
- Job costing is secondary to PM
- Not built for sub workflows
- Per-user pricing on higher tiers
- Limited cost code depth
Pricing: $99-$899/month
Verdict: Built for general contractors managing entire projects. Electrical subs tracking labor against bid breakdowns will find the job costing too shallow.
QuickBooks Online
General accounting software. Not designed for construction job costing.
PROS & CONS
QuickBooks Online
Pros
- Widely known
- Affordable
- Good AP/AR
- Accountant-friendly
Cons
- No cost-to-complete tracking
- No WIP reporting
- No AIA billing
- Cannot compare actuals to bid breakdowns
Pricing: $35-$235/month
Verdict: Fine for bookkeeping but fundamentally wrong for job costing. QuickBooks tells you what you spent. It does not tell you whether what you spent makes the job profitable.
How We Evaluated
We tested each platform against the specific needs of a $3M-$8M electrical subcontractor: the ability to track labor by cost code, compare actuals to bid breakdowns in real time, generate AIA G702/G703 billing documents, and support multiple users without per-seat pricing blowing up the budget.
We did not evaluate estimating, CRM, or marketing features. An electrical contractor buying job costing software needs job costing software, not a business management platform.
The Electrical Sub’s Unique Workflow
Electrical contractors operate under conditions that generic project management tools do not account for. You bid a specific scope to a GC. Your profit lives or dies on whether actual labor and materials match that bid. Change orders from the GC add scope but need to be formally tracked and billed. AIA billing formats are required on most commercial projects.
The software you use needs to understand this workflow natively. Buildertrend and Procore are built for the GC sitting above you, managing the overall project. QuickBooks is built for retail and service businesses. Foundation understands construction but charges enterprise prices for what mid-size shops need.
We built MarginLock because the gap between QuickBooks (cannot do it) and Foundation (costs too much) is where most $3M-$8M electrical contractors live. Flat-rate pricing means your software cost does not scale with headcount.
