ChairFill
SMS reminders with a refundable deposit that cut no-shows for dental clinics in Poland
Real pain, real buyers, one fragile workflow.
You do not yet have a software business. You have two credible buyers and a workflow hypothesis that can still collapse between the booking, the PLN 50 payment, the fiscal receipt and the receptionist’s calendar. That is enough to build a pilot, not enough to build broadly. Your strongest evidence is unusually useful: 6 of 8 owners named the problem, and 2 signed full-price pilot letters. The panel is right about platform dependence and patient friction, but premature in prescribing card pre-authorisation before your current deposit flow has been tested. Launch only on Medfile, handle onboarding manually and make the waitlist recovery engine the product. Paid pilots with clean fiscal handling and no material booking loss change this from promising to proven.
Medium confidence. The interviews and two full-price letters of intent are meaningful, but no live patient deposit, fiscal workflow, API integration or paid renewal has yet been completed.

Biggest risk
The end-to-end deposit and calendar workflow may create more patient and receptionist friction than the recovered slots justify.
ChairFill touches patients, payments, refunds, fiscal records, the main appointment calendar and the waitlist. If any handoff requires repeated manual reconciliation or causes meaningful booking abandonment, clinics will disable the deposit or cancel the subscription.
Must be true
- At least one Medfile clinic can run two-way appointment and waitlist updates without maintaining a second calendar.
- The clinic and its accountant can process payment, deduction, cancellation, refund and forfeiture cases with acceptable front-desk effort.
- Targeted PLN 50 deposits materially reduce no-shows without causing enough booking abandonment to erase the recovered revenue.
What you got right
✓ You found real buyers
Two of eight clinic owners signed letters of intent at the full PLN 399 price, which is materially stronger than polite interview interest.
✓ Your background fits the desk
Three years as a dental receptionist gives you direct knowledge of confirmation calls, calendar gaps and the behaviour of clinic gatekeepers.
✓ You separated the money cleanly
Sending deposits directly to the clinic’s Przelewy24 account avoids making ChairFill the holder of patient funds.
Next steps
- 1
Turn both letters of intent into controlled paid pilots.
Success looks like: Both clinics start the paid pilot, at least 70% of targeted patients complete the requested action, and recovered appointment value exceeds PLN 399 per clinic without an increase in abandoned bookings large enough to erase that value.
- 2
Validate every fiscal and reception scenario.
Success looks like: Both accountants approve the documented flow, and at least 9 of 10 simulated cases are completed correctly in under one minute of extra staff time each.
- 3
Prove the Medfile integration before production development.
Success looks like: Complete the full sequence automatically with no manual duplicate entry, under one minute of sync delay, and a tested error alert for failed writes.
