Internal Business Case Template: New Benefits Platform
Last updated
This template helps HRIS administrators and benefits leaders build the internal business case for replacing a legacy benefits administration platform. It covers status-quo cost quantification, the three options a CFO will evaluate, decision criteria a CFO will weigh, risk-adjusted comparison framing, slide-ready recommendation language, and the approval checklist a CFO needs to sign off. Pair this template with the numerical model in the Benefits Platform TCO Calculator.
Quantify the Hidden Cost of the Status Quo
The first step in any internal business case is making the status-quo cost legible to the CFO. Most CFOs see the existing benefits administration setup as "$0/year" because the spend lives in operating headcount and absorbed errors rather than a contract line. The business case fails when this hidden cost is not surfaced.
Quantify manual reconciliation labor
Document the hours per pay period the benefits team spends reconciling carrier billing, payroll deductions, enrollment files, and eligibility events. Multiply by fully loaded labor rate and annualize. For a 200-employee group, this typically runs $14K to $20K per year. This is the single most concrete hidden-cost number to lead with.
Quantify absorbed errors
Document deduction error write-offs, carrier billing disputes resolved out of operating budget, COBRA notice failures, ACA filing corrections, and missed eligibility events from the past 12 months. For a 200-employee group, this typically runs $5K to $15K per year — half of which is recoverable, half written off.
Quantify compliance exposure
Document at-risk events: late COBRA notices ($110/day excise tax exposure), ACA filing errors ($290 per incorrect 1095-C up to $3.6M annual cap), unverified I-9s ($272 to $2,701 per violation). The expected-value framing — probability of audit times penalty exposure — makes compliance risk legible alongside operating cost.
The Three Options a CFO Will Evaluate
A CFO evaluating a benefits platform investment will consider three options. Naming all three explicitly — including the do-nothing option — strengthens the recommendation rather than weakening it.
Option 1: Status quo
Keep the existing benefits administration setup. Lowest visible cost, highest hidden cost. Appropriate when the hidden cost is genuinely small (very small employee count, single state, very simple plan design) or when the company is in a transitional state that does not justify a multi-year platform commitment.
Option 2: Best-of-breed benefits platform layered on existing payroll
Add a benefits administration platform connected to the existing payroll system via API. Preserves the payroll investment, closes 90% of the silo cost driving Option 1's hidden expenses, implements in 4 to 6 weeks. Software cost typically $4 to $10 PEPM.
Option 3: Full HCM consolidation
Replace the existing payroll system and benefits administration with a single HCM suite. Justified when the existing payroll system has hard limitations beyond benefits (multi-country, complex compensation, planned M&A integration). Software cost typically $20 to $40 PEPM. Implementation 6 to 12 months. Treat this as a payroll-replacement decision, not a benefits administration decision.
Five Decision Criteria a CFO Will Weigh
A CFO will weigh five dimensions when comparing the three options. Address each explicitly in the business case.
Total cost of ownership over three years
Include software, implementation, internal labor, and silo cost. The TCO calculator handles this directly. Lead with three-year TCO rather than annual cost — it makes the implementation cost in Year 1 less load-bearing.
Implementation risk and change management overhead
Option 2 implementation risk is contained because payroll is preserved. Option 3 implementation risk is a multi-system migration with significant change-management overhead. CFOs prioritize implementation risk highly because failed implementations are the dominant negative outcome in this category.
Vendor stability and consolidation roadmap
Document who owns the platform, whether it is independently held or part of a larger portfolio, and whether the platform has been acquired or is on a consolidation path. The Employee Navigator/Ease 2023 acquisition is a recent example where the consolidation path itself became a buying decision.
Data ownership and exit
Document who owns the employee benefits data, what migration rights exist at contract end, and what data export formats the platform supports. CFOs see lock-in risk as a long-tail liability and want explicit exit terms documented before signing.
Compliance and security posture
Document SOC 2 Type II status, HIPAA compliance posture, data residency, and breach notification terms. These are the boundary conditions a CFO needs to clear before TCO becomes a relevant comparison.
Risk-Adjusted Comparison Across the Three Options
| Risk Dimension | Option 1: Status Quo | Option 2: Best-of-Breed + Existing Payroll | Option 3: Full HCM Consolidation |
|---|---|---|---|
| Implementation failure | None (no implementation) | Low — 4-6 week scope, contained to benefits administration | High — 6-12 month scope, payroll migration is the primary failure mode |
| Compliance exposure | Compounds annually | Materially reduced (automated workflows) | Materially reduced after migration completes |
| Vendor lock-in | None for benefits; existing for payroll | Moderate (3-year contract typical, exit terms negotiable) | High (HCM suite migration is structurally hard to reverse) |
| Operating cost growth | Scales with employee count | Sub-linear (silo cost stops scaling) | Linear with employee count |
| Strategic optionality | Low — every future change requires manual rework | High — payroll changes don't require benefits platform changes | Low — committed to HCM suite roadmap |
Slide-Ready Recommendation Language
Use this language directly in board memos, CFO briefs, or platform-evaluation slide decks. The wording is calibrated for executive consumption — concrete numbers, no marketing language, explicit naming of the alternative.
Recommendation paragraph
"After three years of operating cost on the current benefits administration setup, we have absorbed approximately $X in manual reconciliation labor, $Y in deduction error write-offs, and $Z in compliance exposure. We recommend Option 2: layer a best-of-breed benefits administration platform onto the existing ADP system. Three-year TCO is approximately $X (versus $X for status quo with hidden cost included, and $X for full HCM consolidation). Implementation is contained to 4-6 weeks. We do not recommend full HCM consolidation at this time because the existing payroll system meets requirements outside benefits administration; replacing it would represent committed spend without commensurate strategic benefit."
Risk paragraph
"The dominant implementation risk for Option 2 is integration depth between the new benefits platform and our existing payroll system. We will validate this risk in a 2-week UAT phase against a representative employee sample before production cutover. The dominant operational risk for Option 1 is compounding compliance exposure as our employee count grows; year-over-year, status quo cost increases linearly while Option 2 cost grows sub-linearly."
Vendor selection paragraph
"We recommend evaluating two to three benefits platforms in the best-of-breed category before final selection. Selection criteria are: ADP Workforce Now integration depth, multi-EIN handling, per-client configurability, vendor stability and consolidation roadmap, and three-year TCO. We will not evaluate full HCM suites in this round; that decision belongs to a separate payroll-strategy evaluation."

Project Timeline From Sign-Off to Steady State
A typical platform-replacement project follows this timeline from CFO sign-off to steady state.
Weeks 1-2: Discovery and field mapping
Vendor and customer teams align on field-level mappings between the new benefits platform and existing payroll system, deduction code alignment, benefits class structure, and carrier feed configuration.
Weeks 3-4: Validation and UAT
Integration runs against a test environment with a representative employee sample. Sync events, deduction pushes, hire and termination flows verified end-to-end before production cutover.
Weeks 5-6: Production cutover and reconciliation
Full employee population synchronized. Deductions reconciled against the most recent pay period. Benefits enrollment routing switched to the new platform. Steady state typically reached within 30 days of go-live.
Weeks 7-12: Operating-model embedding
Internal team transitions reconciliation labor to platform monitoring. Hidden cost begins to drop. By Week 12, the operating-model change is visible in the next reconciliation cycle.
Measurable Outcomes
Within 12 weeks of go-live, internal teams transition reconciliation labor to platform monitoring. The 90 percent reduction is consistent across mid-market employer groups in the 200 to 800 employee range.
Best-of-breed benefits platforms with productized API integration to existing payroll typically reach steady state in 4 to 6 weeks. The implementation scope is contained to benefits administration; payroll is preserved.
Status quo cost grows linearly with headcount because manual reconciliation labor scales per employee. Best-of-breed cost grows sub-linearly because silo cost stops scaling once the integration is in place.

Schedule a Working SessionFrequently Asked Questions
What is the typical CFO objection to a new benefits platform?
The typical CFO objection is that the existing setup costs nothing on a contract basis, so adding a vendor contract is a net new expense. The counter-objection is that the existing setup costs $20K to $30K per year for a 200-employee group in hidden operating cost (manual reconciliation labor, deduction error write-offs, compliance exposure). Surfacing this cost in the business case converts the comparison from "new spend versus zero" into "new spend versus documented operating cost."
How do I document hidden status-quo cost without sounding like a marketing pitch?
Use internal data only. Pull benefits-team payroll records to estimate reconciliation hours per pay period. Pull A/R aging to identify carrier billing disputes resolved out of operating budget. Pull compliance audit records to identify late COBRA notices and ACA corrections from the past 12 months. The credibility of the hidden-cost claim depends on the data being internal and verifiable, not on rhetorical framing.
Should I recommend a single vendor or evaluate multiple?
Recommend a vendor evaluation process with two to three platforms in the best-of-breed category. Single-vendor recommendations look like a procurement shortcut and weaken the business case. A short evaluation process — typically 4 to 6 weeks for vendor demos, reference calls, and proposal review — strengthens the recommendation without delaying implementation meaningfully.
What is the right contract length for a new benefits platform?
A 3-year contract is typical and appropriate. 1-year contracts give the vendor pricing flexibility to escalate aggressively at renewal. 5-year contracts lock the customer into pricing that may not reflect market changes. A 3-year contract with a capped annual escalator (3 to 5 percent) and a termination-for-convenience clause balances pricing predictability against operating-model flexibility.
How do I address the "we just changed payroll vendors" objection?
If the company changed payroll vendors recently (within 24 months), the CFO will resist any system change. Address this by emphasizing that Option 2 layers benefits administration onto the existing payroll system without replacing it. The integration preserves the recent payroll investment rather than disrupting it. Explicitly contrast this with Option 3 (full HCM consolidation), which the recent payroll change rules out.
