Self-serve booking
Patients book, reschedule, and cancel from a link — the calendar updates itself and waitlisted patients backfill cancellations instantly.
Scheduling software for clinics
Every appointment booked, without the phone tag.
Flowstack replaces the reminder spreadsheet, the no-show calls, and the double-booked Tuesday afternoons with one scheduling flow your front desk actually enjoys.

Features
Everything the front desk does, minus the busywork.
Flowstack is built around the three jobs a clinic schedule has: fill the calendar, keep the appointments, and get paid on time.
Reminder sequences
SMS and email reminders fire on the cadence you set. Clinics typically cut no-shows by a third in the first month.
Waitlist automation
A cancellation is an offer: the next patient on the waitlist gets a text with the open slot — first to tap wins it.
Payments & deposits
Take deposits at booking and balances at check-in. No-show fees enforce themselves politely.
How it works
Live in one afternoon, not one quarter.
Import your calendar
Connect your existing calendar or spreadsheet. We map your providers, rooms, and appointment types in minutes.
Turn on booking + reminders
Drop your booking link on your site and Google profile. Choose the reminder cadence — the default works for most clinics.
Watch the no-shows drop
The dashboard shows fill rate, no-show trend, and revenue per slot — the three numbers that run a clinic schedule.
Proof
Clinics that filled the empty slots.
“No-shows went from 18% to 6% in six weeks. The waitlist texts alone pay for the subscription.”
“We stopped hiring a third front-desk temp. Booking is self-serve and the reminders do the chasing.”

FAQ
The buying questions, answered plainly.
How much does Flowstack cost?
Plans start at $79/month per location with unlimited providers and appointments, billed monthly or annually (two months free). Every plan starts with a free 14-day trial — no card required until the trial ends.
Does Flowstack replace my practice management system?
No — it sits on top of it. Flowstack handles scheduling, reminders, waitlists, and deposits, and syncs appointments back to your PMS through our integrations so nothing is double-entered.
Is patient data secure and compliant?
Yes. All data is encrypted in transit and at rest, access is role-based and audit-logged, and we sign a business associate agreement with every clinic on a paid plan.
What happens if we cancel?
You export everything — calendar, patient contact preferences, and booking history — at any time, and your booking link simply stops accepting new appointments. No lock-in, no exit fees.
