Payroll & Benefits Reconciliation
Reconcile benefits enrollment against payroll deductions and audit 401k, HSA, and employer costs.
Quick answer
- Why do carrier invoices and payroll deductions drift apart?
- Timing. Elections, terminations, and life events take effect on different dates in each system, and retroactive adjustments land in one system before the other. Small monthly differences compound into large annual variances if they are never matched.
- What is a three-way match in benefits?
- It is the comparison of the carrier invoice, the enrollment record, and the payroll deduction for the same person, plan, and period. Any line where all three do not agree is an exception that either costs money or creates a coverage problem.
Why this reporting is hard
Benefits reconciliation fails in the gaps between three systems that rarely agree: what the carrier billed, what the benefits system says the employee elected, and what payroll actually deducted.
This page describes the reconciliation pack that closes those gaps every month, plus the audits that keep 401(k), HSA, and employer cost data defensible.
Reports in this pack
- Three-way matchCarrier invoice against enrollment against payroll deduction, line by line, with unmatched rows isolated for research.
- Enrollment vs. deduction varianceEmployees enrolled with no deduction, deducted with no enrollment, and deductions that do not match the elected plan and tier.
- Terminations and COBRATerminated employees still billed by the carrier, missing COBRA notifications, and coverage end-date mismatches.
- New hire and eligibilityEmployees past their eligibility date with no election on file, and waiting-period calculations by class.
- Dependent eligibilityDependents past the age limit, missing documentation, and dependents carried on plans after a qualifying event.
- 401(k) and HSA auditsContribution and match calculations against plan rules, annual limit tracking, and census extracts for testing and Form 5500.
Metrics tracked

How Praisidio builds it
- Load carrier invoices, enrollment records, and payroll deduction detail into a single monthly dataset.
- Match on a stable identity key rather than name, since carriers and payroll rarely format names the same way.
- Classify every exception by type and owner so research is assigned, not rediscovered each month.
- Track recovered dollars so the process has a number attached to it at year end.
Every report reads from your existing systems - payroll, HRIS, time, benefits, and finance - so there is no data warehouse project and no spreadsheet export step. Reports are scheduled, delivered, and versioned, and every number can be traced back to the source record.

What is a three-way match in benefits?

How long should a monthly reconciliation take?
With the data assembled automatically, most teams close within a few days of receiving carrier invoices. The time goes into researching genuine exceptions rather than building the comparison.
