Top Reasons to Choose GreenMargins for Managing Subcontractors
⏱️ In 30 Seconds
- ✓Who it's for: Landscape contractors who use subcontractors for electrical, concrete, irrigation, tree work, and other trades

- ✓What GreenMargins does: Tracks sub costs by trade, stores bid history, calculates markup consistently
- ✓Key benefit: Know your real cost including subs, and mark up appropriately every time
Subcontractors can make or break your project profitability. A reliable sub at fair pricing is gold. A flaky sub with change orders is a margin killer. Here's why landscape contractors use GreenMargins to manage sub relationships.
Consistent Markup by Trade
Different trades warrant different markups based on your coordination effort and risk. Set and apply markup consistently across all projects.
Bid Comparison by Job
Store multiple sub bids for each job. Compare apples to apples and see which sub offers the best value—not just lowest price.
Historical Pricing Reference
What did the electrician charge per fixture last year? Historical data helps you spot when quotes are out of line—high or suspiciously low.
Subcontractor Performance Tracking
Did they finish on time? Were there callbacks? Track sub performance over time to build your reliable vendor list.
Change Order Management
When subs have change orders, you need to pass them through (with markup) or absorb them. Track all changes to see true final cost.
Self-Perform vs. Sub Analysis
Should you sub out concrete or do it yourself? Compare your crew cost vs. sub bids to make the right call for each job.
Payment Schedule Tracking
Subs often want progress payments on larger jobs. Track when payments are due and ensure you've collected from the client first.
Insurance and Documentation
Store COIs, W-9s, and contracts by subcontractor. Know at a glance who's compliant before you put them on a job.
Sub Cost as % of Project
Are you becoming too dependent on subs? Track sub cost as a percentage of total project cost to understand your business model.
Negotiation Leverage
With data on past projects and competitive bids, you can negotiate better rates with subs who want your consistent business.
📋 Worked Example: Outdoor Kitchen with Multiple Subs
Here's how a landscape contractor would price a project with significant subcontractor involvement:
Project Details:
- • Built-in outdoor kitchen with BBQ island
- • Gas line extension, electrical for outlets/lights
- • Concrete pad, masonry veneer, granite countertops
- • Landscape contractor is GC, coordinating all trades
| Trade/Item | Sub Cost | Markup | Client Price |
|---|---|---|---|
| Subcontracted Work | |||
| Concrete (pad + footings) | $3,200 | 15% | $3,680 |
| Electrical (2 outlets + lights) | $1,850 | 20% | $2,220 |
| Gas line extension | $1,200 | 20% | $1,440 |
| Masonry (block + veneer) | $4,500 | 15% | $5,175 |
| Granite countertops | $2,800 | 10% | $3,080 |
| Subtotal - Subs | $13,550 | — | $15,595 |
| Self-Performed Work | |||
| BBQ appliances (supplied) | $4,200 | 25% | $5,250 |
| Site prep & cleanup | $650 | 50% | $975 |
| Project management (8 hrs) | $480 | 75% | $840 |
| Overhead (12%) | — | — | $2,720 |
| Project Total | $18,880 | — | $25,380 |
Net Profit: $6,500 (25.6% margin) on a project where 53% of base cost was subcontracted
The 15-20% sub markup covers coordination, scheduling, warranty support, and client communications you handle. Without it, you're working for free.
💰 Subcontractor Markup Guidelines by Trade
Use these ranges as starting points, adjusted for your coordination effort and risk:
| Trade | Typical Markup | Factors to Increase |
|---|---|---|
| Electrical | 15-25% | Complex coordination, warranty liability, permit pulling |
| Plumbing/Gas | 15-25% | Safety liability, inspection coordination |
| Concrete/Masonry | 10-20% | Scheduling dependencies, quality callbacks |
| Tree Removal | 10-15% | Liability exposure, property damage risk |
| Irrigation Install | 15-20% | Warranty coverage, system tuning visits |
| Pool/Spa | 5-15% | Often passed through; high dollar = lower % |
| Grading/Excavation | 10-15% | Site access issues, unknown conditions |
| Appliances/Fixtures | 20-35% | Sourcing, delivery coordination, installation |
When to Mark Up Higher
- • You're carrying warranty liability
- • Sub requires heavy schedule coordination
- • You're handling permits/inspections
- • Payment terms mismatch (you pay sub before client pays you)
- • Sub has history of issues/callbacks
When Lower Markup Works
- • Sub handles own warranty directly with client
- • Simple pass-through with minimal coordination
- • Long-term relationship with volume pricing
- • Client selected the sub (you're just facilitating)
- • Very high ticket items (% on $50K pool)
Pro tip: Many contractors under-markup subs because "they did all the work." You're providing sales, project management, client handling, billing, and warranty backstop. That has real value—charge for it.
