Why General Contractors Should Be Charging Referral Fees to Subs
If you are a general contractor, you are probably the single biggest source of referrals for every subcontractor you work with. You send work to electricians, plumbers, HVAC techs, painters, roofers, and flooring installers on a regular basis. Your recommendation carries enormous weight with homeowners because you are managing their entire project. And yet, most GCs send all of this work for free.
That needs to change.
The Value You Are Giving Away
Think about what happens when a homeowner asks you to recommend an electrician for their remodel. You are not just passing along a name. You are transferring your reputation, your trust, and your relationship with that customer to another business. The electrician who gets that referral did not have to spend a dollar on marketing to acquire that customer. They did not have to compete with five other bids. They walked into a job where the homeowner already trusted them because you vouched for them.
That has real, measurable value. A warm referral from a trusted GC converts at 70 to 80 percent. A cold lead from Google converts at 10 to 20 percent. You are giving your subs a 4x advantage in close rate, and most GCs never see a dime for it.
Why Subs Will Agree to This
The most common objection GCs have is "my subs will not go for it." In reality, most subcontractors are happy to pay a 5 to 10 percent referral fee for consistent, high-quality leads. They are already spending 15 to 25 percent of revenue on marketing through Google Ads, Angi, and Thumbtack. A referral fee that is half that cost and delivers a better customer is a no-brainer for them.
The key is how you position it. You are not demanding a kickback. You are formalizing a business arrangement that benefits both sides. The sub gets consistent, pre-qualified leads without marketing spend. You get compensated for the value you are already providing. It is a professional referral fee, not a favor.
How to Structure It
Keep it simple. A 5 to 10 percent referral fee on the final job value is standard in the industry. For a $3,000 electrical job, that is $150 to $300 paid to you for the referral. Set up a written agreement with each sub specifying the percentage, when payment is due (typically within 30 days of job completion), and how job values will be reported.
Start with your most trusted subs — the ones you already refer work to consistently. Have a direct conversation: "I have been sending you a lot of work, and I would like to formalize our referral arrangement. I am proposing a 10 percent referral fee on jobs I send your way. In exchange, you get exclusive referrals for your trade on my projects." Most will say yes immediately.
The Revenue Potential
A GC managing 10 projects per year, each requiring 4 to 6 subcontractors, is sending 40 to 60 referrals annually. At an average job value of $3,000 and a 10 percent fee, that is $12,000 to $18,000 per year in referral income. For larger GCs managing 30 or more projects, the numbers scale to $50,000 or more. This is pure profit from relationships you already have.
Making It Professional
The difference between a GC who earns referral fees and one who does not is professionalism. Track every referral. Use a platform that gives both sides visibility into the pipeline. Pay and get paid through a neutral system. When everything is tracked and transparent, nobody feels taken advantage of — and the referral fees become just another line item in the project budget.
Referly was built for exactly this relationship. Set up your referral agreements, track every sub referral, and let the platform handle fee calculations and payouts. Start earning what your referrals are worth.
