Fractional CFO for Med Spas: Provider Pay, Membership Revenue, and Second-Location Cash

A med spa with $400,000 in the bank and $250,000 of unredeemed packages has $150,000 of its own money. Most owners look at the first number. A fractional CFO for med spas starts with the second, because prepaid treatments, membership credits, and provider commissions all sit between the deposit and the profit.

The job is to separate earned revenue from owed service, set provider pay against the margin that's actually left, and decide whether the first location can fund a second one without borrowing against patients' prepaid visits.

Your deposits are three different kinds of money

Every dollar that comes in falls into one of three buckets, and each one follows its own cash rule.

Retail skincare is a fourth, smaller stream with a product margin, not a service margin. Keep it on its own line so it doesn't flatter service gross margin.

If the P&L blends all of this into "Revenue," you can't tell whether a strong month came from treatments delivered or from a package promotion that pulled next quarter's sales forward. That's the first thing a CFO untangles.

Provider pay: decide what the commission is on

Provider compensation is the largest cost in most med spas, and the plan design matters more than the rate. The question isn't "what percentage?" It's "a percentage of what?"

Here's a hypothetical neurotoxin visit priced at $520 for 40 units, with product cost of $5.00 per unit:

The first row is a full-price patient. Rows two to four are the same visit for a member who used a 20% discount, so the spa collects $416. Contribution ranges from $60 to $164 depending on how the plan reads. The discount case is the one that hurts: when commission is calculated on list price, every membership discount comes entirely out of the spa's share.

The Bennett rule is simple. Pay providers on collected revenue, net of product, for any service where product is a meaningful share of price. Then check the blend against the 60-15-15 standard: across the whole service mix, delivery cost (provider pay plus product plus direct supplies) should leave about 60% gross margin.

Notice what the table says about that. Even the best row keeps only 31% of the $520 list price after provider pay and product, because product alone is 38% of the price. A product-heavy line like toxin won't reach 60% on its own. It has to be carried by lines where product is a small share of price, such as laser, skin treatments, and membership dues. If the blended margin can't get to 60% at a fair provider rate, the pricing or the service mix is wrong, not the provider.

Arron covered this ground, including a salary cap approach to labor cost, on the Med Spa Success Strategies episode. The episode is the conversation. This article is the worksheet.

The med spa numbers a CFO tracks monthly

These are the operating numbers worth a monthly review. None of them is an industry benchmark; they're the measures Bennett uses to locate a margin problem.

• Revenue per treatment-room hour. Collected service revenue divided by open room hours. This tells you whether the constraint is demand, scheduling, or space.
• Provider pay as a percentage of collected service revenue, by provider and by service line.
• Product cost per service, reconciled to purchases. Units injected should roughly match units bought less inventory change; a gap points to waste, comps, or undocumented touch-ups.
• Membership churn and average member tenure. Member lifetime value is monthly contribution per member times expected months.
• CAC payback. Acquisition cost per new patient (new-patient marketing spend divided by new patients) divided by the monthly contribution that patient produces. Bennett's target is six months or less, and LTV:CAC of at least 4:1.
• Rebooking rate within 120 days for toxin patients, since repeat visits drive most of the lifetime value.

If you can't say which service line is carrying the spa, hold off on the comp rewrite and the second lease. A Leak Check focused on your service-line margin sorts out whether the gap is commission design, product use, or price before you change anything providers will notice.

Package and membership cash belongs on the balance sheet first

Prepaid packages are a liability until the sessions are delivered. Membership credits that roll forward are the same. The cash is real, but you still owe the service, and the patient may ask for a refund. The existing guide on refund reserves for prepaid service packages walks through how to size that reserve.

Tax treatment can differ from the book treatment. For accrual-method taxpayers, 26 U.S.C. § 451(c) allows an election to defer part of an advance payment to the following tax year, but not beyond it. That's a one-year deferral at most, and it only covers the portion not already recognized in your financial statements. Cash-method practices follow different rules. Have your tax preparer confirm which applies before a big December package promotion, because a promotion can create taxable income in a year when the spa hasn't delivered the work yet.

Card processing adds one more gap. Processors can hold reserves against chargebacks, which is why card sales are not the same as available cash.

Second location: what location one has to fund

The second-location question is usually framed as "can we afford the build-out?" The better question is "how many months of losses can location one carry while location two ramps, without touching package liabilities?"

A hypothetical example. Location one does $2.4M of collected revenue and produces $36,000 a month of operating cash after owner pay. It holds $180,000 of unredeemed packages and memberships.

At $36,000 a month, location one generates about $360,000 over those ten months. Add $180,000 of cash already in the bank and the plan looks fundable. Except that $180,000 is owed to patients. Take it out and the spa is $120,000 short, before any delay in the ramp.

The fix might be a later opening date, a smaller first phase, or equipment financing with a longer term. It might also be that location one needs a pricing or comp change first. The point is to see the gap before the lease is signed.

What a fractional CFO does in the first three months

Bennett's onboarding uses the first 120 days to rebuild the financial base before the strategy work. For a med spa, the first three months of that look like this.

Month one: separate the money. Rebuild the chart of accounts so services, packages, memberships, and retail each have their own revenue and cost lines. Set up a deferred revenue schedule that ties unredeemed sessions to your booking software. Reconcile product purchases to units used. Run the first clean close.

Month two: price the providers. Build contribution by provider and service line on collected revenue. Model the current comp plan against two alternatives. Size the refund reserve. Start the tax plan, including entity structure, owner pay, and how the next package promotion lands in the tax year.

Month three: model the decision. Build a 13-week cash forecast with package liabilities shown separately from operating cash. Run the second-location model above on your real numbers. Agree on a monthly KPI review against 60-15-15.

That work is part of Bennett's fractional CFO services: one engagement at $5,000 a month, with bookkeeping, tax returns, and tax planning included. If your bookkeeping is current and the immediate problem is just a late, messy close, fractional controller services may be the smaller first step. Practices that do more surgery than aesthetics may find the plastic surgery CFO page a closer fit.

Do one calculation this week: unredeemed packages and membership credits divided by your operating cash. If the answer is above 50%, the bank balance is overstating what you can spend, and a Leak Check on package cash and provider margin is the place to start before any expansion talk.
