The Monthly Benefits Reconciliation Close

Benefits reconciliation works when it is a routine with a fixed date, and fails when it is an activity people get to.

The single biggest determinant of whether it stays manageable isn't headcount or carrier count. It's frequency. A discrepancy caught in the month it occurs costs one month of premium and five minutes. The same discrepancy caught at renewal costs eleven months and a negotiation.

The sequence

Before the invoices arrive

1. Close the change log for the period. Terminations, new hires, life events, class changes. Everything effective in the coverage month should be recorded before you reconcile it.

2. Confirm what was transmitted to each carrier, and when. Reconciliation compares your records to theirs. If a change never left your building, you'll find it as a discrepancy and misdiagnose it as a carrier error.

3. Note each carrier's cut-off date. Changes after cut-off will appear as exceptions this month and resolve next month. Knowing the date is what lets you separate timing from error.

When the invoices arrive

4. Check the invoice totals against the prior month. A material swing with no known cause is a signal to investigate before doing anything line-by-line.

5. Run identity matching. Resolve to a person before comparing anything. Record match confidence.

6. Run the three-way match - invoice to enrollment, enrollment to payroll, invoice to payroll totals.

7. Categorise every exception. Timing, termination not reported, new hire not transmitted, tier or rate error, identity mismatch, carrier error.

8. Separate timing from error. Anything after the cut-off date is expected. Log it as expected-to-resolve and check it next month.

Acting on findings

9. Escalate immediately: payroll deductions for people who aren't enrolled, and enrolled employees never transmitted to a carrier. Both are urgent for reasons beyond the premium.

10. Request adjustments, with the employee identifier, the affected period, the amount, and the reason. Log every request as an open expected credit.

11. Age the open credits. Chase after two cycles. Escalate after three.

12. Approve payment, with disputed amounts documented separately rather than silently withheld.

Monthly checks that aren't invoice-driven

13. Dependents reaching the age limit in the next 90 days.

14. New hires at 30, 60 and 90 days - enrollment transmitted, deduction started, effective dates aligned.

15. Terminations in the period - reported to every carrier, and COBRA notice triggered where required.

16. COBRA participants - elections within their windows, payments within the grace period, the insignificant-shortfall test applied before anything is treated as non-payment.

Closing

17. Record the outcome. What was checked, what was found, what was resolved, what remains open.

18. Review the categories. One category dominating means a process fix upstream, not more reconciliation.

What to escalate immediately

Finding	Why
Deduction with no enrollment	Incorrect payroll withholding
Enrolled but never transmitted to the carrier	The employee has no coverage and doesn't know
Terminated employee still billed after multiple cycles	Compounding cost, and possibly a missed COBRA notice
Credit unreceived after three cycles	It is probably not coming
An invoice total that moved materially with no cause	Something structural changed

What to keep, and for how long

• The invoice as received, unmodified
• Your reconciliation working file for the period
• The exception list with categories and resolutions
• Every adjustment request and the response
• The credit aging report
• For self-billed carriers: the census you remitted, unchanged
• The confirmed identity cross-reference - this one is permanent and shouldn't live inside a monthly file

Retention periods depend on your plan documents, carrier contracts, and applicable recordkeeping rules. Set a policy with counsel rather than defaulting to whatever the shared drive holds.

Signals that the process has outgrown its tooling

• Reconciling last month takes more than a day
• The exception list is long enough that nobody reads all of it
• The same people appear as exceptions every month
• Nobody can reconstruct how a resolved discrepancy was resolved
• Credit tracking lives in someone's head or inbox
• A formula exists that nobody can explain
• Reconciliation happens at renewal because there's no time monthly

Any three of these together mean the tooling is now the constraint, not the process.

Frequently asked questions

How often should we reconcile?

Monthly, on a fixed date. Frequency matters more than depth - a shallow monthly pass beats a thorough annual one.

What if we've never done this and don't know where to start?

Start with one carrier and one month. Categorise what you find. The categories will tell you where the process is broken, and that's more valuable than the first month's recovery.

How long does it take?

Depends on carriers, headcount and data quality. If it takes more than a day for a mid-sized employer, the tooling is the constraint.

Should we withhold payment on disputed amounts?

Document the dispute and follow your contract. Silently short-paying creates a second reconciliation problem on top of the first.

What's the highest-value single check?

The 90-day dependent age-out report. Lowest effort, highest recovery, and it prevents costs you can't recover later.

When should we escalate a credit?

Chase at two cycles, escalate at three. After three it usually isn't coming without intervention.

How Praisidio fits

Praisidio connects payroll, HRIS and benefits data and runs the invoice-to-enrollment-to-deduction match on a schedule, so the exceptions arrive as a list rather than a discovery. See the reconciliation pillar or book a demo.
