Most decisions to launch on-site care are followed by an awkward 6-week silence. The contract is signed, the vendor is “building out the clinic,” and HR has no idea what’s actually happening, what to communicate to employees, or how to know if things are on track.
We wrote this because every HR Director we’ve worked with told us they wished they’d had it on day one. It’s not a sales document. It’s the operational walkthrough — what should be happening behind the scenes, what employees should be hearing, and the milestones that tell you the program is healthy.
Month 0 — Contract signed, decision day
What the vendor does: Confirms site (often: existing space in your HQ, or a leased near-site unit). Begins build-out specs. Assigns the lead nurse practitioner. Sets up the member-facing onboarding flow (eligibility upload, verification page, sign-in).
What you should do as HR:
- Lock in the announcement timing — typically 30 days before clinic opens. Too early creates anxiety; too late and the launch lands flat.
- Get a head start on your eligibility file — your TPA or HRIS should be able to export the data the vendor needs (name, DOB, work email, HSA flag, dependents). Cleaner the data, faster the launch.
- Identify your internal champions — a few employees per worksite who will be the first to verify, post about it on Slack/Teams, and organically pull peers in.
Common Month 0 mistakes: Trying to keep the launch secret. The grapevine always knows, and the rumor mill is worse than the announcement. Negotiating the contract in isolation from finance. Finance owns the ROI conversation in months 4-12 — bring them in now.
Month 1 — Build-out + communications prep
What the vendor does: Construction. Hires + onboards the on-site clinical team. Pre-loads your eligibility roster into the member portal. Drafts the launch announcement email.
What you should do as HR:
- Approve the announcement copy. Most vendors will draft it; treat it as a starting point and rewrite in your company’s voice. The launch email is the single most-read message employees will get all year — make it sound like you, not a benefits vendor.
- Schedule the all-hands kickoff — 15-minute presentation at one of your standing meetings 1-2 weeks before clinic open. The NP attends.
- Pre-register your executives. Nothing kills employee skepticism faster than seeing the CEO and CFO already verified in the system before the launch goes wide.
The pre-launch announcement template (≈3 weeks before open):
Subject: A new health benefit you’ll actually use
Team — Starting [date], we’re opening a primary care clinic [on-site / right next door at [address]]. Sick visits, annual physicals, lab work, and chronic-condition management — all free for you and your covered family members. Same provider every visit. No copays. No surprise bills.
Here’s the 90-second video explaining how it works: [link]. Verify your account now to be ready when the clinic opens: [welcome link]. Questions? Reply to this email or message [HR contact].
Common Month 1 mistakes: Drafting the announcement without involving the NP or clinic manager. Employees will ask “who is this person and why should I trust them with my health?” — a paragraph + photo from the NP in the launch email handles 80% of this skepticism.
Month 2 — Clinic opens
Day 1: Clinic opens. Employees can walk in or book a visit through the member portal. Typical opening-day verification rate: 12-18% of the roster, depending on pre-launch communication discipline. First-week visit volume: 8-15 visits/day for a 350-EE clinic.
Week 2-4: Verification climbs to 35-45% by end of month 2 (the steepest growth period — most employees verify within 30 days of launch). Visit volume stabilizes at ~10-20/day depending on industry mix. The on-site pharmacy (if applicable) starts filling — most fills are generic chronic-condition meds.
What you should be watching: Verification rate per worksite. If one site is lagging the others by >15 points, something specific is wrong there. Fix locally. The first complaint is coming — usually “I tried to book but the slot I wanted was full” or “the NP recommended a specialist — isn’t this supposed to keep me OUT of specialists?” Both are normal. The first means demand exceeds supply (good problem). The second means the NP made a clinically appropriate call.
What good looks like at end of Month 2: Verification rate 35-45%. Engagement rate (≥1 visit) 8-12%. Member satisfaction 4.5+/5. At least one organic Slack/Teams post from an employee saying “I went, it was great.”
Month 3 — Word of mouth kicks in
The biggest jump in engagement isn’t from your announcements; it’s from peer-to-peer. By month 3, ~30-40% of new visits are members who tell us “my colleague mentioned the clinic.” Verification rate plateaus around 50-60%. The last 40% are typically late adopters or members who don’t engage with the health plan at all.
What you should do: Promote a Month 3 visit milestone internally. “We’ve had 150 visits in our first 90 days” creates social proof for the laggards. Send a short Month 3 survey — three questions: Have you used the clinic? If yes, would you use it again? If no, what would make you try it? Open-ended answers to #3 are gold. Common answers: “didn’t know I could bring my kids,” “didn’t realize same-day was an option,” “thought it was only for emergencies.” Each unlocks a targeted comms response.
What good looks like at end of Month 3: Verification rate 55-65%. Engagement rate 22-30%. The first “saved my life” story has happened (rare condition caught early, or a depression intake that led to immediate intervention). This story becomes your most-shared internal anecdote.
Month 4 — Financial break-even
Visit volume has stabilized at ~250-350 visits/month for a 350-EE clinic. Downstream referral reduction starts showing up in claims data — usually a 12-18% reduction in PCP-driven outpatient charges by end of month 4. The clinic is at run-rate cost. Your PMPM is steady. The avoided spend in claims data starts to cross the avoided cost in PMPM.
What you should do: Pull your TPA’s monthly claims summary and compare against the same month last year. You should see: lower count of PCP-coded encounters in claims (because they’re happening at the on-site clinic instead), lower count of specialist referrals, lower spend per encounter on the primary care line. Share the Month 4 number with finance. This is the first meeting where you have hard data. Don’t oversell it — claims data has a 60-90 day lag, so what you’re showing them is partial.
Common Month 4 mistake: Declaring victory. The full ROI signal doesn’t land until months 7-9 when the claims runout completes. Show the trend; don’t yet show the total.
Month 5-6 — The doldrums
Honeymoon’s over. New employee verifications slow to a trickle. Engagement plateaus. Some early adopters fall off (they got their annual physical, they’re not coming back for 12 months). One or two members will have a frustrating clinical experience. Word travels fast inside a 350-employee company.
What you should do: Run a “Have you tried the clinic yet?” nudge campaign. Targeted at the 35-45% of the roster who verified but haven’t booked. A short internal video from the NP usually moves 8-15% of this group. Plan the open-enrollment communication. If your OE is in fall, this is when you start building the OE materials around the on-site clinic as a centerpiece — not an afterthought.
What good looks like at end of Month 6: Verification rate 65-75%. Engagement rate 45-55%. Claims data shows ~18-22% reduction in visit-driven outpatient spend YoY for the rolling 90-day window.
Month 7-9 — Real ROI shows up
The Month 4-6 claims data has fully landed. Your finance team can now reconcile the on-site spend against the avoided spend cleanly. The 12-month ROI projection becomes credible — usually 1.4-1.8× on total program cost depending on population mix. Chronic disease management takes hold. Members with hypertension, diabetes, lipid issues who started visits in months 2-3 are now in their 3rd-4th visit. A1c trends, BP trends, and adherence rates start to look like real clinical wins.
What you should do: Run the “Year-One Outcomes” memo internally. Short — one page. Lead with member-facing wins (visit volume, satisfaction, anecdotes). Bury the financial numbers in the second half so it doesn’t read as a finance memo. Share with your broker and TPA. They will use the outcomes to pitch on-site care to their other employer clients. That’s fine — the network effect helps you renew at better terms.
Month 10-12 — Steady state + renewal prep
The clinic is part of the company. New hires are onboarded into it in their first week. Existing members reference it casually. Visit volume is steady at ~30-50 visits/employee/year of engaged members. Year-2 contract conversations start. Typically a small PMPM step-up reflecting wage inflation; clinical scope can expand (behavioral health hours, women’s health, etc.).
What good looks like at end of Year One: Verification rate 70-80%. Engagement rate (≥1 visit in 12 months) 65-75%. Member satisfaction 4.6+/5. Reduction in visit-driven outpatient spend YoY 18-25%. Total program ROI 1.4-1.8× program cost. HR sentiment internally: “this is the best benefit we’ve ever launched.” CFO sentiment: “the numbers reconcile to what we modeled in month 0.”
Three things that derail Year One
1. Underestimating the communication load in months 1-3. It takes more internal comms than HR teams plan for. Plan for ~7 internal touches: pre-launch announcement, NP intro, launch-day reminder, Week 2 nudge, Month 1 “we’re open and here’s what we’re seeing,” Month 3 survey, Month 6 nudge. Most HR teams plan for 2-3 and wonder why engagement stalls.
2. Treating the NP as a vendor. The single biggest engagement driver is the relationship between the NP and the workforce. Help them build it: introduce them in the launch announcement (name + photo + bio), have them present at the all-hands kickoff, invite them to your monthly safety / wellness meetings, let them attend the company holiday party if they want. The clinic isn’t a place. It’s a person.
3. Sharing financial numbers too early. The first 90 days of claims data are noisy. Sharing them with finance creates false signals (either over-optimistic or under-optimistic). Wait until month 4 for the first internal financial review, and month 7 for the first ROI memo to the CFO.
