Parametric Product Configuration
When the customer sends millimetres and kilograms, not a catalog code, quote from formulas. Sales engineers stop owning every dimension change in Excel.

The challenge
The quote lives in a sales engineer's spreadsheet, not in your CPQ
A dealer emails length 12.4 m, load 850 kg, belt type X. There is no SKU for that exact combination. Someone opens a personal workbook, pastes the numbers, and waits for formulas to spit out price and parts. That someone is usually the same sales engineer every busy week.
Inside sales cannot finish the loop. Channel partners escalate any non-step size. When the customer shortens the run by half a metre, the whole Excel path restarts, and approval waits on a new PDF that still has no shared audit trail.
Option-list CPQ and variant pickers do not solve this. You cannot pre-list every millimetre. Teams either invent fake size steps that production ignores, or they keep parametric quoting outside the system that owns price and approval.
Inquiry to configuration to price to approval to order breaks at the spreadsheet. The product knowledge exists. It is trapped in cells only one person trusts.
How it works
Four steps from parameters to a priced path
1) Product publishes numeric inputs with units and allowed ranges. 2) A rep or dealer enters length, load, flow, or capacity in the configurator. 3) Mercura validates bounds, derives components and BOM lines from the same formulas engineering signed off, and recalculates line price. 4) The configuration moves into approval and order transfer with the parametric values attached. Discrete catalog browsing is the variant page. IF/THEN option logic is rules-based configuration. This page is continuous inputs that calculate a sellable result without a private workbook.
Derivation
Inputs → formulas → derived components
Three ways products are configured
Variant · Parametric · Modular
Variant-based
Select among predefined attribute values.
Frame / voltage / IP / mount
Parametric
Enter dimensional or engineering parameters.
Width / load / flow
Modular
Assemble reusable physical or functional modules.
Base / head / controller
Bundling is commercial packaging around products — not a fourth product-definition model.
What's included
What you put in the parametric model
Input
- Numeric fields for dimensions, capacities, flow, load, and similar inputs
- Min/max and unit checks with clear guidance when a value is out of range
Calculate
- Formula-based price from the live parameter set
Validate
- Derived components and BOM lines from engineering formulas
Derive
- Mixed checks that combine parameters with discrete options
- One parametric model for inside sales, dealers, and self-service
- Parametric values written into quote documents and ERP-ready fields
- Hybrid CTO / ETO lines alongside rules and constraints
The difference
What changes when formulas leave Excel
Personal workbooks
- 01 Sales engineers recalculate every custom dimension inquiry
- 02 Price logic lives in files named after people
- 03 Dealers cannot quote non-standard sizes alone
- 04 One changed length restarts the entire quote cycle
- 05 ERP gets specs retyped from email threads
With Mercura
- 01 Parameters entered in a shared configurator
- 02 Product-owned formulas calculate price and BOM
- 03 Out-of-range inputs blocked before the PDF goes out
- 04 Dimension changes update price on the same configuration
- 05 Parametric values travel with approval and order
Business impact
Where parametric CPQ fits (and where it stops)
Parametric configuration is for products defined by continuous engineering inputs, not for picking a finished catalog code. It sits between discrete variant selection and full engineer-to-order design. Mercura does not replace CAD, FEA, or one-off structural calculation. Formulas and ranges need an owner when products change. If your team already knows how price and BOM should follow length or load, putting that logic in CPQ keeps inquiry, configuration, price, approval, and order on one path instead of a private spreadsheet.
Business impact
Quote custom dimensions faster
Parameters drive price and BOM without a side spreadsheet.
Less spreadsheet engineering
Ranges and formulas evaluated in the configurator.
Automatic component derivation
Supports, panels, and kits follow the inputs entered.
