Step 01
Configuration model
Attributes, dependencies, BOM and pricing sources. Workshops with product and manufacturing.
CPQ
Commerce with CPQ & product configuration
When the product is a rule set, not a static SKU
CPQ in ecommerce is a rules and BOM engine that validates configurations live, reprices from commodities or ERP, and outputs quotes or manufacturing data—typically Next.js + NestJS + ERP.
Industrial machinery, made-to-order furniture or specialised vehicles need a rules engine: what can be combined, how weight and lead time evolve, and how price is built from BOM and live commodity costs. The UI (often Next.js) guides the user; NestJS holds rules, configuration versioning and ERP integration. After confirmation we generate quotes, specs or production outputs aligned with your toolchain.

CPQ
From user clicks to factory-ready specs
The UI collects choices; the truth lives in domain models and integrations — not only in the cart.
BOM as source of truth
Each combination maps to materials and operations — version controlled.
Validation in milliseconds
Users do not discover errors at payment — rules run continuously.
Costs & margin
Tie-in to live commodity tables or ERP — with an audit trail.
Manufacturing outputs
Automated data packages for MES / files — fewer manual re-entries.
Cooperation process
How does our cooperation look like?
A transparent process that leads from idea to finished product
Step 02
Validation engine
Rules implemented in code with tests — not hidden client-side scripts.
Step 03
Pricing & versions
Configuration snapshots, change history, re-pricing when costs move.
Step 04
Checkout & documents
Quotes, orders, exports to production or CAD/CAM as your process requires.
Step 05
Launch & maintenance
Monitoring configuration errors, extending rules without regressions.
Key benefits

BOM trees and dependencies between modules.
Live pricing
Recalculation when commodities or FX change.
Production outputs
Bundles for the shop floor or subcontractors.
Questions about this system type
- How is CPQ different from a simple web configurator?
- CPQ ties rule validation, BOM, pricing and configuration versioning to the backend—one source of truth for web, B2B and APIs, not only the browser.
- Can pricing follow live commodity or material costs?
- Yes—we design repricing services with change audit and ERP or cost-table integration so quotes reflect the current BOM.
- Do you generate CAD or manufacturing outputs?
- Yes where the process requires it—data bundles, specs or integrations into your MES/CAM toolchain with controlled versioning.
