RetireCore: One Platform, Every Retirement Plan Type
Administer 401(k), 403(b), 457(b), Defined Benefit, and Pooled Employer Plans from a single, audit-ready system built for TPAs, sponsors, and recordkeepers.
The current state: retirement administration lives in too many places
If you administer employer-sponsored retirement plans for a living, you already know the shape of the work. A single plan touches recordkeeping, contribution processing, compliance testing, participant management, government filings, and year-end reconciliation. Multiply that by dozens or hundreds of plans, each with its own document, eligibility rules, vesting schedule, and payroll feed, and the operational surface area becomes enormous.
Today, most third-party administrators (TPAs), plan sponsors, and recordkeepers stitch this together from a patchwork of tools. A recordkeeping ledger sits in one system. Compliance tests run in spreadsheets or a separate testing engine. Contribution files arrive by email, SFTP, or a payroll portal and are keyed in by hand. Participant notices, distributions, and loans are tracked in yet another place. The census that drives nondiscrimination testing is rebuilt every plan year from scratch.
This model has worked for a long time because the people doing it are experienced and careful. Skilled administrators hold an astonishing amount of institutional knowledge in their heads: which client sends a malformed file every quarter, which plan has a short plan year, which sponsor always misses the deadline for their Form 5500. The industry runs on that expertise. But it runs on it precisely because the underlying systems rarely talk to each other.
As plan counts grow and plan types diversify, the seams start to show. A firm that once administered a handful of 401(k) plans now also handles 403(b) plans for nonprofits, 457(b) plans for governmental and tax-exempt employers, traditional Defined Benefit pensions, and the newer Pooled Employer Plans (PEPs) that let unrelated employers join a single plan. Each plan type carries its own rulebook, and a general-purpose spreadsheet does not know the difference.
The pain point: complexity, manual work, and compliance risk
The real cost of the fragmented model is not just time, though the time is significant. It is compliance risk and the anxiety that comes with it. Retirement plans are governed by ERISA, the Internal Revenue Code, and Department of Labor rules, and the penalties for getting things wrong are real. A late deferral deposit, a missed nondiscrimination test, an eligibility calculation that lets someone in a month early, or a distribution processed without the right paperwork can each trigger corrections, filings, and in some cases financial liability for the fiduciary.
Here is where the friction shows up most often:
- Rekeying and reconciliation. Contribution data is entered by hand or transformed from mismatched payroll formats, then reconciled against the recordkeeping ledger. Every manual touch is a chance for a transposition error that surfaces months later at testing time.
- Compliance testing under deadline pressure. ADP/ACP tests, top-heavy tests, coverage tests, and 402(g) and 415 limit checks all depend on a clean census. When the census is assembled late, testing is rushed, and a failed test discovered in the final week is far more expensive to correct.
- Participant events handled in isolation. Loans, hardship withdrawals, distributions, rollovers, and required minimum distributions each have their own rules and documentation. Tracking them across spreadsheets makes it easy to miss a deadline or a required notice.
- Version and document drift. The plan document is the source of truth, but when eligibility and vesting live in a separate spreadsheet, the two drift apart. Administrators end up asking, "which version is right?"
- No single audit trail. When a DOL or IRS inquiry arrives, or an annual audit begins, evidence has to be gathered from many systems. Reconstructing who changed what, and when, is slow and stressful.
Underneath all of this is a scaling problem. The fragmented approach ties throughput to headcount. To administer more plans, you hire more people, and each new person has to absorb the same tribal knowledge. That is a hard way to grow a book of business, and it leaves quality dependent on individuals rather than on a system.
RetireCore: administration built around the plan, not the spreadsheet
RetireCore from HolyByte Innovations is an enterprise retirement plan administration platform designed to eliminate exactly that fragmentation. Instead of forcing administrators to move data between disconnected tools, RetireCore treats the plan as the center of gravity and brings recordkeeping, contributions, compliance, and participant management into one compliant workflow.
The core idea is simple: the rules that govern a plan should live in the same system that does the work. When eligibility, vesting, contribution limits, and testing all read from a single source of truth, the manual reconciliation that eats up plan-year evenings largely disappears, and the audit trail builds itself as a natural byproduct of doing the work.
RetireCore is built for the people who carry the operational load: TPAs who administer many plans across many sponsors, plan sponsors and HR/benefits leaders who need visibility and clean filings, recordkeepers who need reliable ledgers and reconciliations, and enterprises running large or complex plan lineups. Crucially, it is designed to handle every major plan type in one place rather than assuming every client runs a plain-vanilla 401(k).
Key features: one platform across every major plan type
The heart of RetireCore is broad, native support for the plan types administrators actually manage. Each type has its own rules, and RetireCore is built to respect those differences instead of flattening them.
401(k) plans
The most common employer-sponsored defined contribution plan. RetireCore streamlines 401(k) recordkeeping, contribution processing, and the compliance tests that trip firms up most: ADP/ACP nondiscrimination testing, top-heavy determinations, and 402(g) and 415 limit monitoring. Eligibility and vesting are driven directly from the plan document, so a participant who crosses an eligibility threshold or a vesting anniversary is handled by the same rules every time. Safe harbor designs, matching and profit-sharing sources, and Roth deferrals are all part of the same clean ledger.
403(b) plans
Used by public schools, universities, hospitals, and other tax-exempt organizations, 403(b) plans carry their own nuances, including the universal availability rule and the way multiple vendors and contracts can coexist. RetireCore is built to handle 403(b) administration with those quirks in mind, tracking contributions, aggregating information across arrangements, and supporting the notices and testing that keep the plan compliant, without pretending a 403(b) is just a 401(k) with a different label.
457(b) plans
Offered by governmental employers and certain tax-exempt organizations, 457(b) plans have distinct contribution limits, special catch-up provisions, and rules that differ meaningfully between governmental and non-governmental sponsors. RetireCore keeps those distinctions straight, so administrators managing a mix of 457(b) plans alongside 401(k) and 403(b) plans are not forced to remember which rule set applies to which client.
Defined Benefit plans
Traditional pension plans promise a specific benefit at retirement, which shifts the administrative burden toward accrued benefit tracking, actuarial coordination, funding, and benefit calculations rather than account balances. RetireCore supports Defined Benefit administration by keeping participant service, compensation history, and benefit accrual data organized and consistent, giving actuaries and administrators a shared, reliable foundation for valuations and payouts.
Pooled Employer Plans (PEPs)
PEPs are one of the most important recent developments in the retirement industry, allowing unrelated employers to join a single plan administered by a Pooled Plan Provider. The appeal is scale and reduced individual employer burden, but the administration is genuinely complex: many adopting employers, each with their own payroll, eligibility, and contribution data, all rolling up under one plan. RetireCore is built for PEP administration, handling the multi-employer structure so a Pooled Plan Provider can onboard and manage many participating employers without rebuilding processes for each one.
Recordkeeping and contribution processing
Across every plan type, RetireCore centralizes the recordkeeping ledger and streamlines contribution intake. Payroll and contribution files flow into a consistent structure, get validated against plan rules, and reconcile against the ledger, replacing the manual keying and format wrangling that consume so much administrator time. The goal is fewer touchpoints, fewer transcription errors, and a contribution history that is trustworthy at testing time.
Compliance and testing in the same system
Because the census and contribution data already live in RetireCore, compliance testing runs against a clean, current dataset rather than a spreadsheet assembled at the last minute. Nondiscrimination testing, coverage, top-heavy, and limit checks read from the same source that drives day-to-day administration, which means problems surface earlier, when they are cheaper and simpler to correct.
Participant management
Enrollment, eligibility, vesting, loans, distributions, rollovers, and required notices are managed within the platform rather than scattered across tools. Participant events follow the plan's own rules, and the record of each event is captured as it happens, which keeps both participants and auditors well served.
Audit-ready records and visibility
Every action in RetireCore contributes to a coherent audit trail. When an annual audit begins or a regulator asks a question, the evidence is already organized in one place instead of being reconstructed from many. Sponsors and HR leaders get visibility into their plans, and administrators get the documentation they need to demonstrate compliance with confidence.

Who RetireCore is for
- Third-party administrators (TPAs): firms managing many plans across many sponsors who need to scale throughput without scaling risk or headcount at the same rate.
- Plan sponsors and HR/benefits leaders: employers who want clean filings, reliable testing, and clear visibility into the plans they are responsible for as fiduciaries.
- Recordkeepers: teams that need dependable ledgers, contribution reconciliation, and participant records that hold up under audit.
- Enterprises and Pooled Plan Providers: organizations running large, complex, or multi-employer lineups, including PEPs with many adopting employers.
How RetireCore changes the day-to-day
Consider a TPA that administers a mix of 401(k), 403(b), and a growing number of PEP arrangements. In the fragmented model, contribution season means chasing files, reformatting them for the recordkeeping system, keying corrections, and hoping the census is clean when testing season arrives. A single misaligned column can cascade into a failed test discovered too late to fix cheaply.
With RetireCore, those same contribution files land in a consistent intake, get validated against each plan's rules, and reconcile against the ledger as part of the normal workflow. Because eligibility and vesting come straight from the plan document, participants are handled the same way every cycle. When testing season comes, the census is already current, so nondiscrimination and limit testing runs against real, reconciled data rather than a last-minute rebuild. If something needs attention, it shows up early.
The compounding benefit is that quality stops depending on any one person's memory. The rules live in the system, the audit trail builds itself, and the firm can take on more plans, and more plan types, without multiplying operational risk. That is the difference between growing a book of business and being limited by how many spreadsheets one team can safely maintain.
