Side by side

Who is each one built for?

OptiMantra is built for cash-based integrative, hormone, IV and functional practices. Charm is a general EHR for independent practices that also serves integrative medicine.

OptiMantra's pricing page lists custom compounding, IVs and tinctures, memberships and packages on its base plan. OptiMantra merged with Cerbo in December 2025, and both products are still offered.

Charm's EHR page describes a certified EHR with quality reporting, which matters if you bill Medicare or other insurance. It also has an integrative medicine page that lists drug and herb interaction checks and an inventory module.

How does pricing differ?

OptiMantra charges a flat monthly fee per practitioner. Charm lets you start free and pay by the encounter, which is cheaper at low volume and less predictable as you grow.

• OptiMantra: one base plan for the first practitioner, a lower fee for each extra practitioner, and add-ons for eRx, two-way texting, fax and an AI scribe (pricing). There is a 15-day free trial with no card, and the subscription is month to month with 30 days' notice. Details are in our guide to OptiMantra pricing and plans.
• Charm: the Free plan covers one provider and up to 50 encounters a month. Above that, Charm moves the practice to the Encounter Plan, which bills per recorded visit with a monthly minimum. The Provider Plan is a flat fee per provider (pricing, pricing FAQ).

Charm has more add-ons. Telehealth, eRx, EPCS, texting, fax, the AI scribe and selling products through the portal are each priced separately below the Provider Plan. Add up the ones you need before you compare the two.

Which is better for intake forms and online booking?

OptiMantra is a little stronger here for a cash-pay practice. Both send forms through the patient portal.

OptiMantra includes online booking and custom questionnaires on the base plan, and its onboarding page says it will import your existing intake forms for you. Charm's patient engagement page lists appointment scheduling, pre-appointment questionnaires and secure messaging through the portal. With Charm, patients request a time and the practice confirms it.

Whichever you choose, the form itself matters more than the tool. See what a good hormone or functional medicine intake form asks.

Which is better for payments, memberships and packages?

OptiMantra. Its FAQ says you can set up recurring memberships, prepaid packages and special pricing, and payments run through Fiserv or Stripe.

Charm's pricing page lists card processing through Bluefin, billing packages and an eCommerce add-on for selling products through the portal. We did not find recurring patient memberships on Charm's public pages, as of November 2026. If you sell a monthly hormone or weight-loss program, ask Charm how it would bill it.

If you collect a lab fee before the first visit, check that the payment ties to the patient record. Our guide to collecting lab fees before the consult covers the timing.

Which is better for labs and supplements?

It is close. Both list direct Labcorp and Quest interfaces and a Fullscript integration.

OptiMantra's integrations page names more specialty and regional labs, including Access Medical Lab, Rupa Health, Boston Heart and Evexia, and adds Wholescripts for supplements. Charm's EHR page lists ready-to-use interfaces for Labcorp, Quest and other labs, with further labs connected through a standard HL7 interface. Charm's Fullscript page says supplements ordered through it ship directly to the patient.

If you rely on a specialty lab, ask each vendor whether that lab is already connected.

What about e-prescribing and telehealth?

Both charge extra for e-prescribing. OptiMantra includes telehealth; Charm charges for it below the Provider Plan.

OptiMantra sells one eRx license that includes EPCS. Charm sells eRx as a monthly add-on per provider and EPCS as a separate payment for a one-, two- or three-year term, with a one-time fee for PDMP access, per its pricing page. Charm's pricing FAQ says telehealth is covered for providers on the Provider Plan.

If you prescribe controlled substances, confirm EPCS and PDMP setup with either vendor before you move patients over.

How do reminders and integrations compare?

OptiMantra includes automated text and email reminders on the base plan. Charm meters texts and voice calls as an add-on, with a monthly allowance on the Provider Plan.

For connecting other tools, OptiMantra offers outbound webhooks and lists HighLevel and Zoho. Charm lists API access as chargeable on its pricing page. Neither lists Zapier. Either route usually needs someone technical to set up, and any tool you connect needs its own BAA. Check yours in our BAA checker.

Do both sign a BAA?

Yes, but OptiMantra is clearer about it in public.

• OptiMantra: it publishes its BAA, last revised August 5, 2026. Its FAQ says you sign it when your trial converts to a paid account.
• Charm: the pricing page lists a BAA and asks you to contact support for details. Get it signed before you add patient data, including on the Free plan.

How hard is it to leave?

Both are month to month by default. OptiMantra asks for 30 days' notice. Charm's pricing FAQ asks for a cancellation email at least seven days before the monthly invoice date, and says account data is kept for two months after cancellation. Charm also offers annual contracts at a discount.

OptiMantra's FAQ says standard migration from another EMR is free. The hidden cost in any switch is rebuilding forms, packages and reminders.

Choose OptiMantra if

• you sell memberships, packages or a monthly program and want them billed inside the EHR
• you want booking, telehealth and text reminders included without counting add-ons
• you order from specialty labs as well as Labcorp and Quest
• you want a published BAA and a flat, predictable monthly fee

Choose Charm if

• you are just starting, record fewer than 50 visits a month and want to begin on a free plan
• your volume is low or uneven, so paying per encounter costs less than a flat fee
• you also bill insurance and need a certified EHR with quality reporting
• you want API access and have someone who can use it

If neither fits, OptiMantra vs Practice Better vs Healthie and OptiMantra vs SimplePractice vs Tebra cover the other common shortlists. For what owners say about OptiMantra after signing up, see our summary of OptiMantra reviews.

What neither one does

Both EHRs work on patients who have already booked. Neither will reply to a new inquiry within minutes, chase an intake form that was started and left, follow up on an unpaid lab fee, or notice when a program patient goes quiet and bring them back. Those steps sit around the EHR, and they are where cash-pay practices lose the most patients.
