FAQ
Common questions about D4W (Dental4Windows) integration.
Does D4W have an API for custom integrations?
D4W's integration options are more limited than cloud-native dental PMS platforms, but we build integrations within the available patterns including portal extensions and online booking.
Where does D4W data sit?
D4W typically runs on-premises in the practice. Custom integrations engineer for explicit data flow controls and Australian residency.
How does D4W compare to Praktika or EXACT?
D4W has long Australian heritage; Praktika is cloud-native; EXACT (Software of Excellence) leads in larger practices and groups. Choice usually comes down to existing investment.
