The challenge
Shipping documents arrive in many layouts from many parties. Staff keyed each field into the operations system by hand, then cross-checked it against the original document to catch mistakes. That review alone took 3 to 4 hours per shipment.
The harder problem was consistency. Every supplier laid out their B/Ls and packing lists differently, so the check depended on whoever was doing it that day. Two people reading the same document could flag different things.
Approach
What we did
Collect real documents
Across senders and layouts, including the messy scans.
Build field extraction
Focused on the fields operations actually uses.
Add confidence checks
Uncertain fields are flagged for review instead of guessed.
Write into the existing system
The team keeps its current workflow.
Technical
Architecture
OCR and field extraction
Layout-aware reading across document formats.
Per-supplier correction rules
Each sender's format quirks are encoded once and applied automatically, so the fix doesn't depend on who catches it.
Confidence scoring
Each field scored; low-confidence fields go to a review queue.
System integration
Validated data written into the client's operations system.
