T&M BILLING FOR SUBCONTRACTORS.

QUICK ANSWER

Time and material (T&M) billing charges for actual labor hours, materials, and equipment used on a job, at agreed rates, instead of a fixed contract price. A defensible T&M rate sheet builds in labor burden, equipment cost, and markup up front, so every T&M ticket is profitable instead of just busy.

Most subcontractors underprice T&M work because the labor rate is built off gross wage rather than fully burdened cost. Payroll taxes, workers' comp, benefits, and small tools all belong in the rate before markup goes on top, or every T&M hour bills at a loss dressed up as a win. The same thing happens with equipment. A machine that bills fuel and an operator but not ownership cost turns a busy T&M month into a break even one, and nobody catches it, because every invoice got paid on time.

THE DEFINITION

WHAT IT MEANS.

Time and material billing is billing for the actual labor hours, materials, and equipment used on a job at agreed rates, instead of one fixed contract price.

Materials and equipment get their own markup lines, separate from labor. Equipment should bill at a cost per hour rate that reflects ownership cost, not just fuel and an operator, or every T&M job ends up subsidizing the fleet. That one line is the difference between T&M work that funds your equipment and T&M work that wears it out for free.

WHAT WE SEE IN THIS BUSINESS

WHERE T&M LOSES MONEY.

01

Rate built on base wage

Quoting the T&M labor rate off gross wage instead of fully burdened cost bakes in a loss before markup is even applied. The number looks right to everybody who sees it, because it matches the wage on the check. What it doesn't match is what the hour costs the company once taxes, insurance, and benefits are in it.

02

No same day ticket and sign-off cadence

T&M tickets signed days later from memory miss hours, materials, and equipment usage, and waiting until the end of the job to collect signatures invites disputes over hours nobody can verify. Nobody reconstructs a Tuesday accurately on Friday. Same day sign-off is the cheapest protection you have, and it costs one conversation per day.

03

Undocumented equipment time

Equipment sitting on a T&M job without a logged cost per hour rate bills at zero. The machine still burns fuel, still depreciates, and still needs service. If it's not on the ticket, the job absorbed that cost and the customer paid nothing toward it.

04

Stale rate sheets

A rate sheet built two years ago doesn't reflect current wage or material cost, and every job billed under it underbills. Wages moved, insurance renewed, and material went up. The sheet stayed where it was, so the shortfall grows a little every quarter until somebody sits down and rebuilds it.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

What belongs in the T&M labor rate

Base wage is the hourly wage paid to the field employee. Payroll burden covers payroll taxes, workers' comp, and unemployment insurance. Benefits load covers health insurance, retirement match, and PTO accrual where it applies. Small tools and consumables cover wear items and small tools not billed as separate line items. Markup goes on top of the fully burdened rate to recover overhead and profit.

COMMON QUESTIONS

FREQUENTLY ASKED.

T&M billing charges for actual labor hours, materials, and equipment used, at agreed rates, instead of one fixed contract price. It's typically used for change order work, emergency work, or scope that can't be estimated accurately up front.
Base wage, payroll burden, benefits load, small tools and consumables, and markup for overhead recovery and profit. A rate built on base wage alone underbills what the labor costs you.
At a cost per hour rate that reflects true ownership cost, depreciation, maintenance, and financing, not just fuel and operator time. Equipment sitting on site without a logged rate bills at zero.
Usually because tickets aren't signed same day. Waiting to submit hours days or weeks later invites the GC to question quantities nobody can verify. Same day sign-off is the single biggest protection against a T&M dispute.
