Contribution Administration Gets Harder When the Agreement Behind the Obligation Is Disconnected.

Pension administrators need to know not only what an employer reported, but what the employer was required to report under the applicable agreement and effective period.

Rates Maintained in Spreadsheets

When contribution rates live outside the system that processes remittances, rate changes introduce errors across every affected employer and period.

Historical Terms Are Difficult to Reconstruct

Without effective-dated records, determining what rate applied to a specific employer in a specific period requires piecing together old documents and emails.

Employer Reporting Reviewed Without Contract Context

Staff validating remittances often can't see the agreement and rate that should have governed the submission — making discrepancy review slower and less reliable.

Retroactive Changes Create Manual Calculation Work

When negotiated rates apply retroactively, recalculating obligations across every affected employer, period, and participant is done manually — if it's done at all.

Maintain the Agreements That Govern Employer Participation.

Every employer has a governing agreement. Pension OS keeps the full agreement history — predecessor, current, and successor — as a structured operational record.

Each agreement preserves its own rates, funds, and classifications — prior terms remain intact when a new agreement takes effect.

Connect Contribution Requirements to the Agreement That Defines Them.

Each employer's contribution terms — rate, classification, fund allocation, and reporting requirement — are maintained inside the applicable agreement record.

Apply the Correct Terms to the Correct Reporting Period.

Changing today's rate should not change yesterday's obligation.

Each rate record is effective-dated and tied to the agreement that produced it. When a new agreement takes effect, prior periods remain governed by the prior terms — queryable for audits, corrections, and retroactive adjustments.

  • Each rate tied to the agreement that defined it
  • Prior periods remain accessible after agreement changes
  • Employer-specific and classification-specific terms preserved
  • Retroactive lookups use the rate that actually applied

Connect Employer Reporting to the Appropriate Contribution Structure.

When agreement rates are structured inside Pension OS, each employer remittance is automatically validated against the applicable terms.

Handle Retroactive Contribution Changes Without Rebuilding Prior Periods by Hand.

When a negotiated contribution rate becomes effective in an earlier period, Pension OS can support recalculation of affected obligations while preserving the history of the original reporting and subsequent adjustment.

Trace the Obligation Back to the Rule That Created It.

Every contribution obligation has a clear lineage. Pension OS makes that lineage visible — from the employer through the agreement, rate, period, hours, and expected amount down to the reconciliation outcome.

Agreement-sourced obligations
Every expected contribution traces to the agreement and effective rate that produced it — not to a spreadsheet.
Period-level precision
The correct agreement and rate are applied to each specific reporting period.
Audit-ready lineage
Any obligation can be reconstructed — from employer identity through contribution amount — without searching external records.

Stay Ahead of Agreement and Rate Changes.

Agreement expirations, rate step-ups, and retroactive adjustment reviews are operational deadlines — not calendar reminders. Pension OS surfaces them while there is still time to act.

  • Agreement expiration alerts with configurable lead time
  • Rate change effective-date notices
  • Employer participation agreement end alerts
  • Successor agreement deadline reminders
  • Retroactive adjustment pending review notifications

Make Employer Contribution Agreements Part of the Actual Administration.

More Accurate Contribution Processing

Expected obligations are derived from structured agreement data — not from spreadsheet lookups.

Fewer Rate & Period Errors

Effective-dated rates ensure the correct amount is applied to each reporting period.

Stronger Reconciliation

Reported amounts are compared against agreement-derived expectations — surfacing discrepancies before they become problems.

Historical Accuracy

Prior agreement terms are preserved when new agreements take effect — so past obligations remain traceable.

Better Traceability

Any obligation can be traced from employer through agreement, rate, period, and expected amount.

Less Key-Person Dependency

Agreement terms and rate history are in the system — not in one administrator's memory.
