🔧 Workflow

Customs brokers or foreign trade sales reps upload PDF or image versions of invoices and packing lists. The system automatically recognizes item names, quantities, amounts, gross and net weights, and combines them with HS code rules to generate customs-formatted drafts. Humans only handle final verification and declaration submission. Multiple batches of documents are processed daily, billed per document, and frequently used client templates are saved. The daily workflow: clients send documents via WeChat or email, which enter the workflow to output editable customs draft templates. After human review of key fields, the draft is sent back to the client.

🛠 Setup Requirements

Requires familiarity with customs declaration form completion standards and HS code classification logic. Technically, it involves using Python or low-code platforms to call OCR and Large Language Model (LLM) APIs, paired with Excel or lightweight databases to manage client templates. Going from zero to taking orders takes about 3-6 weeks, with a one-time upfront API testing cost of under 2,000 RMB. During the initial stage, you can use existing AI document tools such as LaiZhi Intelligent or DataEase solutions to verify results, avoiding the need to develop from scratch.

💰 Revenue

① Pay-Per-Document (Primary Revenue): Customs brokers, freight forwarders, and SMB foreign trade enterprises pay per document generated, at 20-50 RMB per document. Multiplying 300-700 documents processed monthly yields an estimated monthly income of around 15,000 RMB, accounting for roughly 100% of monthly revenue (pay-per-document is the sole revenue stream listed in this card, sourced from case studies without independent verification; time frame is 2026); ② Monthly Subscription Packages: Long-term cooperative clients settle on a monthly basis for stable cash flow (monthly unit prices and number of contracted clients are undisclosed, and their share of total revenue is unquantified); ③ Cost Reduction via Template Library Reuse: Reusing the same workflow to serve multiple clients brings per-document costs down to 0.8-1.5 RMB with a gross margin of over 80% (this item only provides costs and gross margin, without revenue-sharing ratios, self-reported by merchants without external verification); ④ Opportunity Item – Efficiency Premium Pricing: Industry cases show that agent-assisted document specialists increased their daily processing volume from 30-50 documents to 150-200 documents, boosting document generation efficiency by 4 to 5 times and achieving response speeds 5-10 times that of humans. Pricing per document can be adjusted upwards accordingly, though no estimation model is currently available for the additional revenue generated.

💸 Cost

Primarily consists of LLM API and OCR call fees, with a per-document cost of about 0.8-1.5 RMB, plus cloud servers and software subscriptions totaling around 1,000-1,500 RMB per month. If using ready-made SaaS tools, initial development costs can be avoided, and tool subscription fees can be factored into the per-document cost to maintain a gross margin of over 80%.

⏱ Time Investment

2-4 hours per day, concentrated on batch processing and exception correction after clients upload documents. The remaining time is spent on template tuning and acquiring new clients. Weekends can be used to review error cases from the week, continuously optimizing recognition accuracy and HS code recommendation logic, without requiring 24/7 on-call availability.

🚀 Getting Started

Start by finding 1-2 local customs brokers or foreign trade companies, offering to verify results on 10 documents for free while compiling invoice and packing list samples into training templates. Once the workflow is validated, switch to pay-per-document pricing. Use existing AI document tools for initial testing to avoid developing from scratch. The first step is collecting real invoice and packing list samples to confirm whether OCR recognition accuracy and customs draft formats meet client expectations.

🔑 Keys to Success

✅ Secure fixed customs broker or freight forwarder clients to build a stable source of document volume
✅ Prioritize customs declaration format accuracy over full automation; final human review is indispensable
✅ Accumulate a library of common HS codes and client templates to improve accuracy with usage
✅ Keep pay-per-document pricing simple and transparent to facilitate client acceptance and payment
✅ Reuse the same workflow to serve multiple clients, driving marginal costs down to almost zero
✅ Integrate with customs paperless declaration systems to minimize secondary data entry

⚠️ 风险

⚠️ Customs declaration errors may trigger tax assessments or fines, requiring a final human review safety net; completely delegating to AI carries legal risks
⚠️ Customs broker client document formats vary widely, and OCR recognition failure rates may exceed expectations, requiring continuous supplementation of training samples
⚠️ Low-price competition may compress per-document profits, and some clients may choose to use free tools themselves
⚠️ LLM API cost fluctuations or policy changes could impact gross margins, necessitating regular evaluation of alternative tool solutions
⚠️ Client documents involve commercially sensitive information; data security and non-disclosure agreements must be established in advance
