VAS Printing

Running a print-broker model manually hits four bottlenecks: pricing is uncontrollable because each print shop's costs shift constantly by quantity tier, material and production time — pricing via spreadsheets leads to selling at a loss or losing orders; orders 'drift' when price and shipping change after the customer has ordered, causing disputes and revenue mismatches; production fragments when a multi-item order must be split across several print shops and shipments, impossible to track by hand as volume grows; and there is no operational data — no way to measure real profit margin, each shop's on-time delivery rate, or reseller commissions.

• The business architecture is organized into six linear layers, each with clear data boundaries and no permission to skip ahead.
• Product Normalization: standardize the internal print catalog and map it to the partner print shops' products.
• Pricing Decision: compute price from real cost plus margin, then publish it as an immutable price snapshot.
• Order Lock: lock the entire price, shipping fee and chosen print shop in an atomic transaction right at checkout.
• Fulfillment & Supplier Execution: push orders automatically via the print shop's API, or fall back to a controlled manual processing queue.
• Shipping & Tracking: ship by production group, consolidating tracking across multiple carriers.
• Finance / Marketing / Reports: cash flow, commissions, campaigns and reports — read only from locked data.
• An inviolable design principle: the frontend only reads the price snapshot and never computes price itself; marketing cannot edit prices outside the Pricing Engine — eliminating the entire class of 'displayed price differs from charged price' bugs.
