The situation
DFI Synergy ran a busy general + hygiene practice on a paper diary, supplemented by WhatsApp confirmations and a separate billing spreadsheet. The setup worked when the clinic was smaller — but as appointment volume grew, three problems became routine.
- Reschedules made on WhatsApp didn't always reach the diary in real time, occasionally producing double bookings.
- Billing was reconciled at end-of-day. The same-day-bill rate sat at 60%; the rest were follow-ups that cost staff time and aged into receivables.
- Recall outreach was manual. Patients due for hygiene at six months were tracked in a spreadsheet that nobody updated consistently.
Why Oralstack
DFI Synergy evaluated three options to replace the paper-and-WhatsApp setup: continue with Plato (the dominant Singapore PMS), Open Dental, or Oralstack. The shortlist came down to two requirements neither legacy option met cleanly.
The first was a schedule the front desk could drive in seconds, not consult through forms — drag-to-reschedule with timezone-correct commits, inline new-patient registration, recall candidates surfaced before they aged. The second was billing tied to the chart so treatment lines populated themselves at discharge, with insurance and patient portion structurally separate.
Oralstack was chosen on a third factor as well: APAC region hosting, with a tenant-isolated data model designed against Singapore PDPA from day one. The clinic agreed to a three-week handover with no fallback diary kept in parallel — a deliberate forcing function.
