For Every Client, Every EIN, Every Plan

ACA & Benefits Admin for PEOs

You’re managing benefits for dozens or hundreds of employers — each with different workforce structures, plan designs, and compliance exposures. Selerix gives Professional Employer Organizations the expertise to handle it all without building separate processes for every client.

One Platform. Every Client. No Blind Spots.

A PEO’s value to its clients is that the complexity is handled. The problem is that the complexity doesn’t disappear — it consolidates at the PEO level, across a portfolio that’s growing, changing, and carrying real ACA exposure at every client simultaneously.

Most benefits platforms were built for single employers. They don’t surface risk across a portfolio, they struggle with non-standard data from multiple client systems, and they leave the burden of multi-client oversight on your team rather than the technology. Selerix was built for a different model — one where the platform does the monitoring and your team does the advising.

Where PEOs Need More Than a Standard Benefits Platform

ACA Compliance Across Every Client — Not Just the Ones You’re Watching

A penalty notice at one client isn’t just their problem — it’s a question about whether your operation caught it. ALE status shifts, part-time populations grow, coverage gaps go unflagged. You’re managing a lot of EINs, and by the time a notice arrives, the window to correct it has closed.

Selerix provides year-round visibility across your entire portfolio so risk surfaces before it becomes a notice, not after.

Flexible Plan Administration Across Clients With Different Rules

No two clients have the same benefit structure, and a platform that handles one client’s configuration cleanly often forces the next one into a workaround. Workarounds across a growing portfolio accumulate into liability.

BenSelect configures each client’s plan design, eligibility rules, and enrollment workflows independently, with ACA tracking and benefits administration running together so data stays aligned without manual reconciliation.

The Subject Matter Expertise Your Clients Expect You to Have

Most PEO clients don’t have deep ACA expertise internally — that’s part of why they work with a PEO. When a hard question surfaces, they expect an answer from you, not a referral elsewhere.

Selerix functions as an extension of your compliance team, handling the edge cases generic platforms can’t, so when a client brings you a difficult question, you have the expertise and documentation to answer it.

WE UNDERSTAND WHAT YOU NEED

Where PEO Compliance Gets Complicated

When ACA risk is accumulating across your client portfolio

A single employer can monitor their own exposure. A PEO has to monitor everyone’s — simultaneously, year-round, without dropping one to focus on another. Selerix provides portfolio-level visibility into ACA eligibility, ALE status, multiple EINs, and penalty exposure across all clients, so nothing goes undetected until it’s too late.

When a client’s workforce data doesn’t fit a standard import

Clean, standardized data is the exception in PEO administration — not the rule. Selerix handles non-standard imports, data from multiple systems, and workforce structures that generic platforms reject, so onboarding a complex client doesn’t require rebuilding their data from scratch.

When different clients need different plan designs

One client’s contribution structure doesn’t look like another’s. Selerix supports distinct plan designs, eligibility rules, and enrollment experiences per client — all within one platform — so you’re not maintaining parallel systems or making exceptions that create risk downstream.

When hard compliance questions need real answers

PEO clients expect expertise, not a referral elsewhere. When a controlled group determination, an ICHRA arrangement, or a mid-year acquisition changes the compliance picture, Selerix provides the subject matter depth and documentation to back up the advice you’re already giving.
