🔧 Workflow

Clients submit old photos and restoration requests (such as HD upscaling, coloring, scratch removal, etc.) through multiple channels including WeChat Mini Programs, Pinduoduo shops, and Douyin direct messages. The system automatically identifies the photo type and calls the corresponding AI model for batch processing. Once processing is complete, HD finished products are automatically generated and pushed to the client. Upon client confirmation, payment settlement is automatically triggered. The entire process requires no manual intervention, with a processing time of no more than 2 minutes per photo.

🛠 Setup Requirements

Basic proficiency in Python or Node.js development is required, along with familiarity with the deployment and fine-tuning of open-source restoration models such as Stable Diffusion, Real-ESRGAN, and DDColor. Procure a GPU cloud server from Alibaba Cloud or Tencent Cloud (recommended configuration: 8 cores, 16GB RAM or above). Complete the registration of a WeChat Mini Program/Pinduoduo shop, AI interface integration, and payment gateway setup. The overall setup period is about 2-3 weeks, with a total initial investment cost not exceeding 2000 RMB.

💰 Revenue

① Mini Program/e-commerce shop per-photo coloring and restoration (main revenue): settled per photo, basic restoration at 30 RMB per photo, averaging 200-500 orders per month resulting in 6,000-15,000 RMB (the range extracted is 6,000-12,000 RMB/month), accounting for 100% of monthly revenue (case study retold, not independently verified, based on 2026 observation standards); ② Value-added services (elderly photo album customization, digital photo albums): raises the per-customer transaction value to 80-150 RMB, revenue fluctuates with order volume, exact proportion not specified in the card; ③ Batch and damaged photo orders: batch restoration packages ¥200-500/group, damaged single photos ¥80-200 (listed platform prices directly verifiable), actual order volume figures and exact revenue share are unknown; ④ Opportunity item - fully automated order system setup agency: providing system setup services or subscriptions for peers, with quotation and closing figures yet to be determined.

💸 Cost

Fixed costs: GPU cloud server approx. 150 RMB/month, no such cost if using a local graphics card; Variable costs: Third-party model API call fee approx. 0.5-2 RMB/photo, WeChat Pay/Pinduoduo transaction fee approx. 3%, total monthly cost approx. 300-500 RMB.

⏱ Time Investment

2-3 hours per day, mainly used for handling customer inquiries, reviewing the quality of AI-generated finished products, and managing abnormal chargebacks. The batch processing phase is fully automated with no manual intervention required.

🚀 Getting Started

Step 1: Search and download open-source old photo restoration projects on GitHub (such as official DDColor and Real-ESRGAN projects), run and test basic functions locally like HD upscaling, coloring, and scratch removal; Step 2: Register a WeChat Mini Program or personal Pinduoduo shop, complete AI interface integration and payment gateway activation; Step 3: Publish before-and-after restoration case studies on Xiaohongshu, Douyin, and elderly community groups, launching a first-order 9.9 RMB trial promotion to attract the initial batch of seed users.

⚠️ Changes in e-commerce platform rules resulting in shop bans
⚠️ Decline in per-customer transaction value below 10 RMB due to intense competition in similar services
⚠️ Copyright disputes arising from old photos provided by clients leading to complaints
