The Challenge
The Problem with Configuring Modular Products
Many manufacturers produce products built from interchangeable modules — machine bases, functional heads, control units, interface panels, and expansion modules that can be combined in multiple configurations. This modularity is a manufacturing strength, but it creates a sales challenge: how do you enable reps and customers to assemble valid, priced configurations from a module library without deep product knowledge?
Without a modular configurator, the assembly process defaults to manual specification — a back-and-forth between the customer, the sales rep, and an applications engineer that takes days and still produces errors. Module compatibility is rarely documented clearly enough for non-specialists to navigate confidently.
Standard CPQ tools model products as hierarchical option trees — a structure that doesn't map well to modular assembly logic. The result is either an oversimplified configurator that can't represent your actual product architecture, or a custom development project that becomes impossible to maintain.
As your modular product range expands — new modules, new compatibility matrices, new pricing structures — the burden of maintaining an accurate, usable configurator grows. Without the right tooling, product catalog changes become engineering projects rather than business operations.
How It Works
How Modular Configuration Works in Mercura
Mercura models modular products as assemblies of reusable component objects — each module defined once with its own attributes, pricing, and compatibility rules. When a user builds a configuration, they select modules from a library that is dynamically filtered to show only compatible options at each assembly step. Module interfaces define what can connect to what, enforcing compatibility structurally rather than through warnings. Pricing accumulates as modules are added, with support for module-level list prices, bundle discounts, and formula-based calculations. The same module library can serve multiple product lines — changes to a module propagate automatically across every product that uses it.
What's Included
Key Capabilities
- Reusable module library shared across product lines
- Interface-based compatibility — modules connect only where valid
- Guided modular assembly with step-by-step selection flow
- Accumulated pricing as modules are added to the assembly
- Module substitution suggestions when preferred option is unavailable
- Multi-level modular BOM generation from assembly output
- Module-level technical documentation surfaced during selection
- Centrally managed module library — updates propagate instantly
The Difference
Before and After Modular Configuration
- Modular assembly requires applications engineering involvement
- Compatibility errors discovered after quote submission
- Module pricing calculated manually per quote
- New module introductions require sales training cycles
- No self-service possible for modular product assembly
- Sales and dealers assemble modules independently with confidence
- Incompatible module combinations structurally prevented
- Prices accumulate automatically as modules are selected
- New modules available immediately upon catalog update
- Full self-service modular assembly via sales or dealer portal
Real-World Application
Example Use Case: Machine Tool Manufacturer
A machine tool manufacturer produces CNC machining centres from a modular architecture — base units, spindle heads, tool changers, coolant systems, and control panels available in multiple variants with defined compatibility rules. Their product range supports over 800 valid modular configurations. Previously, building a configuration required a specialist application engineer and took 2–3 days. After implementing Mercura's modular configurator, the company's sales team and 8 dealer partners self-serve all standard modular configurations. Quote time dropped from days to under 30 minutes.
Quote turnaround dropped from 3 days to under 4 hours.
Business Impact
Why Modular Product Configuration Matters
Modular manufacturing is a competitive advantage that many manufacturers fail to fully commercialise because their sales process cannot keep pace with their product architecture. Mercura bridges that gap by turning modular product logic into a guided, self-service configuration experience. The result is faster quoting, a wider range of configurations accessible to sales and partners, and a product catalog that can grow without requiring proportional growth in applications engineering support.
