Winning With General Contractors Without Losing Your Shirt

The Premise

Working with GCs can feel like a choice between steady work and steady resentment. You carry all the risk and they squeeze every change order.

But here’s the truth: You do not have to swear off GCs to stay sane and profitable. You just have to stop playing the game on their terms.

Jump To:
01

Understand the game you’re actually in

Most subs walk into GC relationships thinking: “They get us steady work, we do great work, the money will sort itself out.” That’s not the game.

From a lot of GC perspectives, you are a risk sponge, a cash buffer, and a scapegoat. You do not have to accept that dynamic.

A simple mindset shift:

“I am not lucky to be on their job. They are lucky to have a trade who can execute cleanly and keep their client off their back.”

02

Not all GCs deserve your sweat

You cannot treat every GC like a long-term partner. Some are just chaos with a logo.

Tier 1 – Keep and protect

They pay on time, send clear bid packages, and look for solutions. Give them first right of refusal and invest in the relationship.

Tier 2 – Use, but on your terms

Payments are fine but slow. Scope is rushed. You stay, but you reduce exposure and price in the friction.

Tier 3 – Fire politely

Always chasing payment. Every job is a "favor". Crew hates the site. Fix it with a clean break.

03

Price like a business, not a desperate sub

If you are losing money, it’s usually because you under-priced the risk or let scope creep eat your margin.

  • Stop hiding overhead: Your price must cover labor, materials, supervision, insurance, and PROFIT.
  • Build in disruption: Add a disruption factor (10-15%) for tight sites or chaotic owners.
  • Get paid for mobilization: Moving crew and trucks is not free. Include mobilization and remobilization fees.
04

Scope: write it like a lawyer

Scope is where most of your profit leaks out. "Can you just take care of that?" is a trap.

Make inclusions and exclusions brutally clear. Spell out exactly what is included (areas, fixtures, tasks) and what is excluded (after-hours, other trades' mistakes).

The Change Order Rule

“No free work. No retroactive begging.” If it's outside scope, flag it in writing, send a price, and do not proceed without approval.

05

Payment terms: stop being the bank

In too many GC relationships, subs are effectively providing interest-free financing.

Tie start to paperwork. Do not mobilize without a signed subcontract or PO. Define pay app cadence and late payment triggers. And limit exposure on risky clients-don't let one client take you down.

Stop financing other people's projects

Book a working session and we will help you restructure your proposals, pricing, and GC strategy so you can protect your margin and your sanity.
