Manual quoting + manual RFQ replies
Goal
Faster response, more orders

Pain Points

1

High RFQ volume

Dozens of RFQs a day; slow replies lose to competitors.

2

Complex quoting

Many specs and complex price tables make manual quotes error-prone.

3

Late follow-ups

Inquiries lack systematic follow-up, leaking potential orders.

How We Built It

01

RFQ parsing

Auto-parse RFQ requirements into specs and quantities.

02

Auto quoting

Calculate and generate quotes from price tables and rules.

03

Follow-up reminders

Auto routing, follow-up reminders and script suggestions.

Not betting on one AI — combining the right few

For a real business scenario, we don't lock in a single technical path up front. We evaluate candidate paths on the same benchmark, then design a hybrid so each path does what it's best at.

General LLM API

Public-cloud models such as GPT-4o / Qwen / DeepSeek

  • ✓Out-of-the-box, minimal integration cost, cheap to start
  • ✕Limited generalization to vertical domains, unstable field-level accuracy, separate compliance design
Best for cold start and quick validation

Industry fine-tuned model

Domain fine-tuning of open-source models on industry data

  • ✓Grasps industry semantics, much higher accuracy, private deployment
  • ✕Needs labeled data plus ongoing training and upkeep
Best as the primary path for high-frequency traffic

RAG + rule engine

Retrieval-augmented knowledge plus business rule checks

  • ✓Highly targeted, explainable, best latency and cost
  • ✕Requires continuous data-loop investment
Best for fallback and high-certainty scenarios

Fusion, not selection

What we deliver is not a single model but a fused pipeline of primary path + semantic correction + graceful fallback: routine cases are handled by the industry model in seconds; low-confidence fields are re-understood by an LLM; on service anomalies the system degrades to a general API and flags manual review — achieving accuracy, cost, latency and controllability at once.

An explainable, degradable, evolvable AI pipeline

We treat AI engineering as a pipeline, not a black box: every step has clear responsibilities, inputs/outputs and fallbacks. The five-step pipeline plus four-layer architecture below is the technical skeleton.
