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.
A Consortium/Third Party Administrator (C/TPA) is an entity that provides drug and alcohol testing program management services to employers on their behalf. Under DOT regulations, employers are responsible for having a compliant testing program — but they can outsource the day-to-day management of that program to a C/TPA.
This is where your business comes in. As a trained collector who understands DOT regulations, you are well-positioned to offer C/TPA services to employers in your area — managing their random pools, coordinating collections, handling paperwork, and keeping them compliant year-round.
A pool of multiple employers combined for the purpose of meeting random testing rate requirements. Every safety-sensitive employee across all member employers goes into a shared pool.
Critical use case: Owner-operators (solo truck drivers) cannot satisfy the random testing requirement on their own — they must join a consortium. This is a massive market of potential clients for your business.
An entity that manages the administrative elements of a DOT testing program on behalf of an employer — scheduling tests, managing CCFs, coordinating with labs and MROs, and handling compliance records.
Key legal point: The employer always remains legally responsible for their program. A TPA acts on their behalf — this distinction matters when you explain your services to clients.
These are the services employers need managed — each one is a potential revenue stream for your business.
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.
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.
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 organizations and staffing firms often need ongoing pre-employment and random testing programs for large numbers of workers across multiple locations.
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.
