CASE STUDY · MINI-APP

Northwind Logistics, the freight calculator that closes the sale.

European multimodal carrier (road, rail, maritime) operating 80+ corridors. B2B freight calculator with instant computation, PDF quote generation, integration with their internal TMS. Wired to real-time fuel rates and country-by-country taxes.

Our commercials spent 2 hours on a quote. Now the client generates it themselves in 90 seconds and we handle the acceptance.

Commercial direction · Northwind
Brief

Industrialise the complex multimodal quote.

Northwind computed quotes on Excel with complex business rules (volumetric weight, country taxes, fuel surcharges, insurance options). Each quote took 2h and created discrepancies between commercials. Goal: a public self-service calculator, with automatic PDF quote generation and TMS sync.

Constraints

Real-time fuel rates · 80 corridors · multi-currency.

Fuel surcharges change daily per corridor. Taxes vary by departure and arrival country. The calculator had to support EUR, USD, GBP, CHF. Generated quotes had to be timestamped, digitally signed and archived 7 years for customs compliance.

Approach

Business-rule engine · external rate sync · PDF generation.

Calculation engine with declarative business rules (custom DSL), versionable. Hourly sync with external fuel rates (Argus). Server-side PDF generation with digital signature. Automatic push to internal TMS (REST) on client acceptance. Multi-currency with daily ECB rates.
