🔧 Workflow

At 9:00 AM every day, synchronize the material demand lists, technical specifications, and drawings submitted by the purchaser. The AI automatically extracts core parameters (such as fiber optic strain accuracy, crack displacement range, etc.) and then batch-blasts inquiries to the vertical domain supplier database. At 6:00 PM, aggregate all supplier quotes, and automatically generate a multi-dimensional price comparison report including parameter matching degree and total cost of ownership. Humans focus on reviewing abnormal quotes and parameter errors or omissions before outputting the final cost reduction recommendation. Collect a 10%-30% commission on the cost reduction amount from the purchaser according to the agreement.

🛠 Setup Requirements

Requires mastering the parameter configuration methods of document parsing tools and being able to build an automated workflow from document input to quote aggregation. You need to deeply cultivate 1-2 vertical engineering material fields in advance (such as structural monitoring sensors, industrial seals), and accumulate at least 50 valid supplier contact numbers and historical quotation data. The overall setup cycle is about 2-3 weeks. No code writing is required in the initial stage; low-code workflow tools can complete it.

💰 Revenue

① Cost reduction commission from small and medium-sized engineering purchasers (main income): Purchasers pay commissions based on actual cost reduction amounts, with a commission ratio of 15%-30%. The average cost reduction for medium-sized projects is 50,000-80,000 RMB = single project commission of 7,500 RMB-24,000 RMB. Undertaking 2-4 projects per month = monthly income of 30,000-60,000 RMB, accounting for about 100% of monthly income (converted according to case descriptions, without independent verification); ② High cost reduction large project tier: Under the same commission mechanism, a single project cost reduction of 127,000 RMB and a commission of 19,000 RMB. How much such large orders account for in total income is not listed separately (case level figures, no third-party verification); ③ Annual full-entrustment annual framework: Purchasers fully entrust 3 types of engineering material price comparison businesses for the year, sign annually, and take commissions per project. How much the annual framework was signed for and how many orders were signed cannot be found (case statement, lack of independent review), and it is unclear how much it accounts for the overall; ④ Opportunity item - Vertical supplier dynamic price database opened to peers and suppliers by monthly subscription. The monthly fee pricing is not public, and how much income it can contribute is also left blank.

💸 Cost

Subscription expenses for document parsing platforms plus workflow tools fall between 300-500 RMB per month; call expenses on the large model side are about 200-300 RMB per month. Adding the two together, the fixed monthly cost is about 500-800 RMB, with no other expenses.

⏱ Time Investment

Invest 2-3 hours a day, mainly used for supplier quote anomaly troubleshooting, manual verification of parameter matching results, and docking with purchasers for requirement confirmation; spend 1 hour on weekends to update the vertical domain supplier price database.

🚀 Getting Started

The first step is to choose a niche engineering materials field you are familiar with (such as bridge monitoring sensors, industrial hydraulic components), and use free tools to practice parsing industry specifications into standardized parameter tables. The second step is to connect with 3-5 small and medium-sized procurement enterprises through engineering industry communities and bidding platforms, provide them with 1 free price comparison service to verify the effect, and then sign a long-term cost reduction commission agreement.

🔑 Keys to Success

✅ Ability to accurately extract technical parameters of complex engineering materials and screen for errors and omissions
✅ Ability to design and implement tiered cost reduction commission agreements
✅ Ability to continuously maintain the underlying supplier dynamic price database in vertical fields
✅ Ability to capture and match purchasers' hidden needs (delivery cycle, warranty requirements, adaptability)
✅ Ability to manually screen abnormal quotes and prevent supplier fraud risks

⚠️ 风险

⚠️ Errors in specification parameter parsing may lead to procurement selection errors, requiring strong human judgment as a safety net to avoid liability
⚠️ Procurement processes of some large enterprises are closed, rejecting external price comparison intervention, resulting in longer negotiation cycles
⚠️ Suppliers collude to drive up quotes and then falsely reduce prices, leading to insufficient actual cost savings and shrinking commission income
⚠️ Failure to timely synchronize after updating vertical field parameter standards results in invalid price comparison results leading to customer complaints

📌 Real Cases

📌 In a bridge monitoring project in Shenzhen in 2025, the agent automatically compared prices of 5 fiber optic sensor suppliers, and after identifying redundant parameters, achieved a cost reduction of 42,000 RMB, earning a commission of 12,600 RMB at a 30% commission rate
📌 In an industrial seal procurement project for a factory in Jiangsu in 2026, price comparison helped the purchaser save 127,000 RMB in costs, with a commission of 19,000 RMB. Subsequently, the enterprise became a long-term client, stably providing 1-2 price comparison projects per month
📌 In a municipal engineering structure monitoring project in Zhejiang, the agent compared quotes from 8 suppliers, eliminated 3 quotes with non-compliant parameters, and finally saved 78,000 RMB in selection, obtaining a commission of 11,700 RMB. The purchaser subsequently fully entrusted the annual price comparison business for 3 types of engineering materials
