How Enrollment Fees Work
Membership plans can charge a one-time enrollment fee, based on either the number of patients on the membership or a percentage of the plan’s total.
Where to Find It
On a membership plan, go to the Enrollment Fees section and use the Based on selector to choose which model to use.
- Number of patients: A fee per tier, based on how many patients are on the membership.
- Plan amount: A percentage of the membership’s total charge for the cycle.
By Number of Patients
With Number of patients selected, define one or more tiers:
- Click Add fee.
- Enter the patient count the tier starts at, and the fee to charge at that tier.
- Repeat for each additional tier.
SigmaMD charges whichever tier matches the membership’s current patient count. For example, tiers of “1 patient: $10.00” and “2 patients or more: $20.00” charge $20.00 once a second patient is added.

By Plan Amount
With Plan amount selected, enter a percentage between 0.01% and 100%.
For example, a plan totaling $200 for the cycle with a 10% enrollment fee charges a $20.00 enrollment fee.

The plan total already accounts for seats, group discounts, and any price cap, so a plan-amount fee recalculates automatically whenever one of those changes the membership’s total, including after enrollment. A tiered fee only changes when a patient is added or removed; a percentage-based fee moves with the total itself.
Naming the Fee on Invoices
For either model, you can optionally set a 'Name on invoice'; this replaces the default "enrollment fee" label patients see on their invoice and during enrollment.
What Patients and Staff See
- During enrollment, staff see the calculated fee next to the enrollment fee toggle (for example, "Yes ($20.00)").
- On the patient’s enrollment summary and invoice, the fee shows with either the custom name set on the plan or the default "enrollment fee" label.
Good to Know
- An enrollment fee is always billed on the same invoice as the first cycle charge; it’s never split out as a separate, standalone charge, even when a tiered fee would otherwise apply (for example, a plan that bills in arrears).
- Switching an existing plan from Number of patients to Plan amount doesn’t require the tier setup used by the old model.
