Adding C/TPA Services to Your Drug Testing Business

Once you're established as a collector, offering Consortium/Third Party Administrator services is one of the most powerful ways to grow recurring revenue and build long-term employer relationships.

New to this? A Consortium/Third Party Administrator manages employers’ DOT testing programs on their behalf. Not sure what the role involves — or how a consortium differs from a TPA? Start with the primer, then come back here for the service menu.

Services You Can Offer as a C/TPA

These are the services employers need managed — each one is a potential revenue stream for your business.

Random Pool ManagementRun the random selection process for your employer clients. Use a scientifically valid method, notify employers when employees are selected, and maintain selection records. This is the core service for consortium members.
Employer Policy DevelopmentHelp employers create DOT-compliant drug and alcohol policies. Many small businesses and new trucking companies have no policy in place — and they're required to have one. This is a high-value service you can charge for separately.
MRO CoordinationServe as the communication link between employers and their Medical Review Officer. You don't need to be an MRO — you coordinate the relationship, track result timelines, and ensure employers receive reports promptly.
FMCSA Clearinghouse ManagementHelp employer clients set up Clearinghouse accounts, conduct required annual queries on all CDL drivers, and ensure violations are properly reported. Many small trucking companies don't know how to navigate the Clearinghouse — this is a service gap you can fill.
Record Keeping & Compliance MonitoringMaintain testing records on behalf of employers, prepare annual MIS reports, send compliance reminders, and provide audit support. Ongoing compliance management keeps clients locked in long-term.
Collection Site CoordinationWhen an employee is selected or a test is required, you handle the scheduling — connecting the employee with a qualified collection site and managing the paperwork flow from collection through MRO report.
Operational Readiness

What You Need to Deliver These Services

1
Deep knowledge of Part 40 and agency regulationsYou must understand the rules before you can manage compliance for others. Your DOT collector training is the foundation — build on it with study of the specific agency regulations (FMCSA, FAA, FRA, etc.) your clients are subject to.
2
Relationships with labs, MROs, and collection sitesYou need a network in place before you sign clients. Establish accounts with a certified lab, identify MRO partners you can refer clients to, and know which collection sites are in your service area.
3
A software or tracking systemYou'll need a way to manage multiple employer accounts, track random selections, log results, and send notifications. That's exactly what our Random Pool Manager does — audit-defensible random selections, per-employer records, results tracking through return-to-duty, and DER/donor notifications — pay-as-you-go with no monthly fee.
4
Client contracts and service agreementsAlways have a written agreement with every employer client. The contract should outline exactly what you manage, what they remain responsible for, fees, and how either party can terminate. Have an attorney review your template.
5
Errors & Omissions (E&O) insuranceWhen you're managing compliance for other businesses, professional liability coverage is essential. A missed random selection or a documentation error on your part could expose your client to DOT penalties — and expose you to liability.
Target Market

Who Needs C/TPA Services

Owner-Operators

Solo CDL drivers are legally required to be in a random consortium — they cannot satisfy this requirement on their own. This is a large, underserved market with a clear compliance need and low friction to sign up.

Small Trucking Companies

Companies with 1—10 CDL drivers often have no formal compliance program. They need random pools, policies, Clearinghouse management, and record keeping — and usually no internal staff to handle it.

Construction & Trade Employers

Many contractors and trade businesses run non-DOT drug-free workplace programs and need help managing them — policy development, collection coordination, and record keeping.

Healthcare & Staffing Agencies

Healthcare organizations and staffing firms often need ongoing pre-employment and random testing programs for large numbers of workers across multiple locations.

Building Recurring Revenue

Most C/TPAs charge employers a monthly or annual fee per enrolled employee or per program — separate from per-test collection fees. Common pricing models include a flat monthly consortium membership fee for owner-operators ($50—$150/month is typical in the market) plus per-collection fees when a test is ordered.

As your client base grows, this recurring revenue compounds — and because compliance doesn't stop, neither does the relationship. C/TPA services are one of the most effective ways to shift from transactional revenue to predictable monthly income in a drug testing business.
