exocad DentalCAD Perpetual vs Flex Licensing: What Makes Sense for Your Lab
exocad's licensing model gives labs two paths: a traditional perpetual license (buy it, own it) and Flex (pay per use). The marketing framing makes Flex sound universally appealing — lower upfront cost, flexibility — but the math tells a different story depending on your volume. Here's the honest breakdown.
Perpetual License: The Traditional Model
A perpetual exocad DentalCAD license is a one-time purchase that gives you the software indefinitely. Annual maintenance and support fees apply (typically a fraction of the initial cost) and provide access to updates. After the initial investment, your per-unit software cost approaches zero.
Who Benefits from Perpetual
- Labs with consistent, predictable volume — the software cost gets fully amortized quickly
- Labs planning to use exocad long-term — no dependence on continued per-use pricing
- Larger labs where the break-even against Flex is reached quickly
- Labs that want module flexibility — perpetual users can add specific modules (implant planning, orthodontics, etc.) as needs grow
The Break-Even Calculation
If a perpetual license costs $X upfront and Flex costs $Y per design, the break-even is X/Y designs. At that point, perpetual becomes cheaper. For most active labs doing crown and bridge daily, this break-even is typically reached within the first year or two of operation.
exocad Flex: The Pay-Per-Use Model
Flex uses prepaid design credits (tokens) that are consumed with each design job. No large upfront cost. You pay as you work.
Who Benefits from Flex
- New labs that don't yet have consistent volume — capital-efficient way to start
- Labs with highly variable or seasonal volume — credits don't expire immediately, so you're not paying for downtime
- Overflow capacity — a lab that primarily uses another CAD platform but occasionally needs exocad for specific case types
- Offices setting up limited in-house lab capability — may not design enough cases to justify perpetual
Where Flex Gets Expensive
At high volume, per-design costs compound quickly. A lab designing 25–30 cases per day will exceed the perpetual break-even in months. At that point, continuing on Flex is paying a perpetual software tax on every unit forever.
Cost Comparison Framework
| Scenario | Perpetual Advantage | Flex Advantage |
|---|---|---|
| Startup lab, first year | Lower total cost if volume materializes | Lower initial risk |
| Established lab, 20+ designs/day | Significantly lower per-unit cost | No advantage |
| Seasonal/irregular volume | Pays even on slow weeks | Only pay when designing |
| Multi-seat lab | Per-seat cost amortizes across team | Credits shared across users |
| Software unsure — testing exocad | High commitment risk | Ideal for evaluation |
Module Considerations
exocad DentalCAD has a modular structure — implant planning (exoplan), orthodontics, dentures, and others are add-ons. Perpetual licensing allows you to add modules as your services expand. Flex pricing for modules varies. If you're planning to expand into implant planning with exoplan, factor the module costs into both license scenarios.
The Honest Recommendation
If you're an established lab with consistent volume, buy perpetual. The long-term economics are unambiguous. If you're launching a new lab or evaluating exocad for the first time, Flex is a rational entry point — just recognize that it's a temporary structure, not a permanent strategy, and plan the transition to perpetual once volume justifies it.
