B2BPaper

Overview

B2BPaper is the central product: a marketplace platform where paper mills list surplus inventory (via their existing Excel/email workflow) and buyers receive AI-matched surplus notifications based on their registered specifications. The platform handles matching, newsletter generation, container assembly optimization, and geographic visibility controls.

The name reflects the market: business-to-business paper trading. The platform is sometimes referred to as "the Paper Surplus Marketplace" in internal documents.

Business Model

Build Status

68 out of 68 original stories complete. All original phases are done. One stalled task remains (inline reel calculator, agent died at commit 753ea6c). The project has 741 passing tests across pytest and Playwright.

Architecture

The platform follows the wiki/concepts/four-layer-architecture (Data Bootstrap, Entity, Action, Output) with wiki/concepts/six-core-entities and wiki/concepts/eight-core-actions. Business logic is organized via the wiki/concepts/service-layer-pattern.

Core Design Principles

1. wiki/concepts/zero-friction-mill-pattern -- mills keep using Excel and email; the platform adapts to them
2. wiki/concepts/three-pillars -- every feature respects Credit, Documentation, and Trust
3. Spec-based matching -- technical specifications drive all matching, not free text
4. Geographic visibility -- regional controls, not per-buyer
