Real-Time Quoting Platform for a Highly Regulated Logistics Provider
Developed by R. Paulo Delgado.
Prompt and professional delivery. We are very satisfied with the excellent personal contact and service delivered to us.
Manual, CEO-dependent quoting replaced by real-time, systemized pricing.
Client Context
The client was a small but strategically positioned logistics company operating in a highly regulated niche: the transportation of animals into and out of Germany. Only a limited number of operators were active in this space due to regulatory barriers, airline constraints, and operational complexity.
The company handled complex, high-stakes logistics requiring precise coordination across airlines, destinations, animal-specific requirements, and transport conditions. Pricing accuracy and response time were critical to winning and executing business.
The Problem
The company's quoting process was entirely manual and exceptionally complex. Quotes depended on many variables such as distance, airline, kennel size, animal type, and numerous conditional factors accumulated over years of operational experience. The logic was undocumented, implicit, and concentrated in the CEO's personal expertise.
Key challenges included:
Manual, non-scalable workflows
Preparing a single quote routinely took an hour or more, required significant manual effort, and could not be parallelized.
Executive bottleneck
Only the CEO was capable of producing accurate quotes, consuming senior management time and limiting business throughput.
Operational risk
The process was highly error-prone and dependent on institutional knowledge rather than a reliable system.
Failed prior system attempt
A previous custom development effort was abandoned without source code, leaving no viable foundation to build upon.
This was not a matter of optimizing an existing workflow, but of replacing a fragile, person-dependent process with a reliable system.
The Solution
I designed and delivered a custom quoting platform that externalized complex domain knowledge into deterministic, system-driven logic.
The solution addressed several architectural focus areas:
- 1
Domain extraction and modeling
Pricing logic and operational rules were extracted from the CEO and experienced staff and formalized into explicit system logic.
- 2
Core quoting engine
A deterministic, parameter-driven quoting engine was implemented to handle complex combinations of variables consistently.
- 3
Operational application
A user-facing application was built to allow staff to generate quotes in real time during customer calls.
- 4
Document generation
The system generated professional quotes in email or Microsoft Word format for immediate delivery to customers.
- 5
Persistence and reuse
Customer records, quote history, and orders were stored to support reuse, templating, and operational continuity.
Architecture & Technology
Core Platform
- C# application with structured business logic layer
- Deterministic pricing and rules evaluation
- Microsoft SQL Server for persistence of customers, quotes, and orders
Infrastructure
- On-premises deployment
- Security practices aligned with existing infrastructure
Application Layer
- Desktop-based operational interface
- Real-time quote generation during customer interactions
- Document export for Word and email delivery
Reliability & Operations
- Stable architecture designed for long-term daily use
- Conservative design prioritizing clarity and maintainability
- Minimal ongoing changes required over many years
Execution & Delivery
The engagement covered full system responsibility, from requirements discovery through delivery and long-term support.
Key characteristics of delivery:
- Worked under high domain complexity with undocumented rules
- Translated tacit operational knowledge into explicit, testable logic
- Validated outputs against real historical scenarios
- Focused on durability and operational reliability
- Provided long-term support and selective enhancements
The system was designed to be depended on daily, not optimized for short-term delivery metrics.
Outcomes & Impact
- Quote preparation time reduced from approximately one hour to real time
- Quoting responsibility expanded beyond the CEO
- Improved customer response times
- Reduced management involvement in routine tasks
- System became a core dependency of the business for many years
The platform became a foundational system supporting the company's operations over the long term.
Why This Project Matters
This project demonstrates the ability to:
- Formalize complex, undocumented domain logic into reliable systems
- Remove structural bottlenecks in small but critical organizations
- Deliver durable, reliable software that becomes a company mainstay
- Operate as a long-term technical partner rather than a short-term vendor
