What Is a Paper Contractor?

A paper contractor is someone who holds the prime contract with the client - whose name is on the paperwork - but subcontracts all the physical construction work to trade specialists. They win the job, manage the delivery commercially, and keep the profit on the spread between what the client pays and what the subs cost. The physical work is done by others. The contractor is on paper.

This is construction arbitrage by an older industry name. The concept is not new, the model is not complicated, and the mechanics are the same whether you call it paper contracting, construction arbitrage, or construction management contracting. You win the work. You sub it out. You keep the spread.

What "paper contractor" actually means#

The phrase comes from a straightforward observation: the contractor exists on paper. Their name is on the contract with the client. Their company holds the prime obligation. But when the work starts, it is tradespeople - plumbers, electricians, roofers, tilers - who are on site doing the physical build.

The paper contractor's job is commercial and managerial: price the job correctly, find and vet the right tradespeople, schedule the work, handle the client, and make sure the job closes out properly. No tools required.

Gary W. Moselle and William D. Mitchell wrote a book called Paper Contracting: The How-To of Construction Management Contracting published by Craftsman Book Company. It describes the model precisely: "The paper contractor manages the day-to-day construction, but never has any field employees, nor does he have any equipment beyond a phone, a laptop computer, and a calculator." That description was written decades ago. The model has not changed.

What has changed is the language. What the industry used to call paper contracting, it now often calls construction management contracting, particularly on larger commercial and public sector projects. The structure is identical. On most large federal, state, and municipal jobs in the US today, the prime contractor is a paper contractor - they hold the contract, manage the trades, and the physical work is done by a stack of specialist subcontractors.

The spread: where the paper contractor makes money#

The profit in paper contracting is the spread between the client price and the sub cost.

Say a client pays $45,000 for a bathroom remodel and a kitchen update. You price the trades at $28,000. Your overhead - insurance, business registration, admin time, site visits - runs $3,000. You net $14,000 on the job, having done no physical work yourself.

That spread is your fee for winning the work, managing the delivery, carrying the contractual risk, and making the project go right from start to finish. It is not a free lunch. The paper contractor is the person the client calls when something goes wrong. That liability is real, and the spread has to account for it.

The size of the spread varies by trade, job complexity, and market. I have seen margins run from 15% to 40% on residential work depending on how competitive the client acquisition was and how well I had the sub-stack priced. The numbers will be different in your market - but the structure is the same.

How I came to understand this model#

I started doing the work myself. First jobs, I was on site. Changed washers, fixed leaks, handled whatever I could while I found trades for the rest. Then I brought in a plumber because the plumber was faster - not because I could not do it, but because an hour sourcing the next client was worth more to the business than an hour under a sink.

From one plumber I went to two, then started taking handymen. Then I tried to find ways not to be on site myself, so I used trades who had their own transport and did not need me there to supervise every job. Then I worked on building systems so I was not managing each job manually.

Then came the hinge point: a trip to Scotland that forced me to try subcontracting most of my jobs. It worked. I came back and subcontracted everything, kept a small in-house team for things that genuinely needed it, and contracted the rest out. I was a paper contractor without knowing the term for it. I was running construction arbitrage before I had a name for it.

By the time I had 1,400+ subcontractors in the database, I was operating exactly the model the book describes: a phone, a laptop, and a well-built sub-stack.

Paper contractor vs. the negative use of the term#

Not everyone uses the term neutrally. In some circles - particularly among tradespeople who do physical work - "paper contractor" is a pejorative. It describes someone seen as collecting a cheque without having the skills or experience to back up the role they are playing.

That criticism has some legitimacy when aimed at operators who are genuinely incompetent - who cannot spot bad work, cannot manage a trade sub, and hide behind a contract when things go wrong. A paper contractor who cannot do their actual job (commercial management, quality oversight, client communication) is a problem. The model requires real skill. It just is not trade skill.

There is also a completely different and illegal use of the phrase. In some cases, "paper contractor" refers to someone who uses another person's contractor licence number on bids or contracts - borrowing the licence to win work they are not qualified or licensed to do themselves. This is licence fraud. In California, it is covered by Business and Professions Code 7027.3 and can be charged as a felony carrying up to three years in prison. This is not the model being described here and it is not something to approach.

The legitimate paper contractor holds their own licence (where required), their own insurance, and takes genuine contractual responsibility for the outcome of the job. The fraudulent use of the term describes something entirely different.

The compliance layer you cannot skip#

Acting as the prime contractor - having your name on the contract - triggers licensing requirements in most jurisdictions regardless of whether you pick up a tool. The licence is about contractual responsibility, not about trade skill.

In most US states, general contracting above a certain dollar threshold (often $500 to $1,000 in materials and labour) requires a state contractor licence. State licensing boards vary: California uses the Contractors State License Board (CSLB), which requires a licence for any work above $500. Texas requires registration with the Texas Department of Licensing and Regulation for certain work categories. Check your state licensing board for the exact requirements.

In the UK, the Construction Industry Scheme (HMRC) governs how a main contractor pays subcontractors. You register as a contractor with HMRC, verify your subs, make the required deductions from payments, and file monthly returns. This applies from your first sub payment.

In Canada and Australia, requirements vary by province and state. The model is legal everywhere; the compliance layer differs. The full breakdown by country is in is construction arbitrage legal.

The question of whether you need a contractor licence specifically for the paper contracting model - where you sub everything out - is answered in detail in do you need a contractor licence for construction arbitrage.

Paper contracting is what most GCs already do#

Most general contractors who have been operating for more than a few years are already paper contractors in the legitimate sense. They win the prime contract. They build a sub-stack. They keep the spread. They do not do the physical work themselves.

According to NAHB research, the typical US residential builder subcontracts around 84% of construction costs and uses 24 different subcontractors to build a single home. Over 90% of builders always subcontract core trades - plumbing, electrical, HVAC, foundations, drywall. The paper contractor model is not an edge case. It is the industry default.

The full breakdown of what general contractors actually do on a job - and how little of it is physical - is in do general contractors actually do any of the work themselves.

Construction arbitrage is the name for building this model deliberately from the start - setting up the sub database, the quoting process, the client pipeline, and the delivery management before you take your first job, not after your tenth. The construction arbitrage profit margins post covers what realistic spreads look like and how to protect them as you scale.

The paper contractor exists on the contract, not on the tools. That is not a shortcut. It is a business model - one the industry has been running for decades under various names.
