🔧 Workflow

Every morning, receive contracts pending review uploaded by clients via office IM channels such WeChat Work and DingTalk. First, filter out confidential contracts using keywords. For non-confidential contracts, call the DeepSeek judicial large model, combine it with the exclusive compliance clause library of the client's industry for risk point scanning, and output a review report with red annotations. At the same time, automatically generate compliance supplementary clauses based on the client's business scenario, and finally synchronize the results to the client's work group or private knowledge base. Batch contracts exceeding 10 copies are automatically processed through the Dify batch processing stream, eliminating the need for manual review copy by copy.

🛠 Setup Requirements

Requires basic operational knowledge of low-code workflow building tools like Dify or FastGPT, an understanding of China's Civil Code, Company Law, and special compliance regulations for target industries. Rent a medium-compute server from Alibaba Cloud or Tencent Cloud (8-core 16G is sufficient for initial needs). Collect and organize contract templates, compliance clause libraries, and historical risk case libraries for target industries in advance. Building and testing the first set of systems takes about 10 to 15 days. No deep programming foundation is required, and beginners can get started quickly through official tutorials.

💰 Revenue

Charging 10,000 to 20,000 RMB for private deployment per enterprise, which includes system setup, clause library customization, and initial employee training. Subsequently, charge an annual system maintenance, regulatory update, and feature iteration service fee of 3,000 to 5,000 RMB. If simultaneously serving 5 to 8 enterprises in different industries, the stable monthly income can reach 30,000 to 50,000 RMB. If developing a standardized SaaS version charged by annual subscription, the annual fee per client is about 2,000 RMB; accumulating 100 paying clients can achieve annual revenue of over 200,000 RMB.

💸 Cost

Cloud server rental is about 9,000 RMB annually, averaging 750 RMB per month. Open-source large model API call expenses such as DeepSeek are 500 to 1,200 RMB per month, tiered based on contract processing volume. Domain names, SSL certificates, and advanced feature subscriptions for tools like Dify cost about 1,200 RMB annually, averaging 100 RMB per month. Early-stage clause library collection and organization can be crawled independently from public regulatory websites without additional fees. The overall fixed monthly cost is about 1,350 to 2,050 RMB.

⏱ Time Investment

Investing about 3 to 4 hours daily, including 1 hour for client requirement communication and system parameter adjustments, and 2 hours for processing batch contract review requests and updating regulatory libraries. If the client's system runs stably, only 1 hour of routine maintenance per week is needed. The remaining time can be used to develop new vertical industry versions to expand the client base.

🚀 Getting Started

The first step is to register an account on the official Dify platform, import open-source large models with legal scenario capabilities such as DeepSeek-V3, upload 3 to 5 typical contract samples to test review accuracy, and organize contract risk point cases for 2 to 3 target industries (such as e-commerce, cross-border trade, and technology services). Then, publish "SME AI Contract Review Private Deployment" service information in local SME owner communities, legal communication groups, or platforms like Taobao and Xianyu. The first order can be built at a low price or even for free as a trial version for local micro and small enterprises, and prices can be raised after accumulating cases.

🔑 Keys to Success

✅ Construct a private vector knowledge base from client historical contracts and local regulations to ensure review accuracy meets legal requirements.
✅ Standardize the format of review reports, outputting annotated documents that legal staff can directly modify to reduce client usage costs.
✅ Emphasize private deployment and data isolation to dispel SMEs' concerns about data leaks, highlighting the differentiation from cloud-based SaaS.
✅ Embed the review process into existing office IM tools like WeChat Work and DingTalk so clients can use it without switching systems, significantly lowering the usage barrier.

⚠️ 风险

⚠️ Legal AI output results still require final verification by human lawyers. If model hallucinations cause enterprises to bear losses, it may lead to disputes, so the boundary of responsibility must be clarified with the client.
⚠️ The later-stage maintenance cost of private deployment is relatively high, and client churn will cause server resources to idle and lead to losses. Annual service agreements must be signed in advance to lock in long-term revenue.
⚠️ If contracts involve state secrets or core commercial secrets, using cloud API processing may violate relevant provisions of the Data Security Law. Data storage locations must be clarified with clients in advance, and confidential contracts must use local offline deployment solutions.

📌 Real Cases

📌 Referring to the Yifacomm intelligent contract risk management system, an independent developer built a private AI review stream for two manufacturing enterprises in the Greater Bay Area, saving enterprises about 80 hours of legal review work per month, equivalent to over 20,000 RMB in outsourcing costs, while the developer's monthly service fee income is about 12,000 RMB.
📌 Maka AI contract tools under Andu Technology have provided contract review services for over 2,000 SMEs. Individual developers can serve 3 to 5 clients per month through agent customized deployment services, increasing monthly income by an average of 15,000 RMB.
📌 Runjian Co., Ltd.'s launched ASEAN AI legal agent Luoni Lawer integrates trade compliance clause libraries from China and 10 ASEAN countries, providing contract compliance review services for cross-border trade enterprises. The annual service fee per enterprise exceeds 20,000 RMB, and it has been implemented in over 50 cross-border trade enterprises.
