Business Automation · E-commerce

EC Operations Automation — Shopify × Kintone × Shipping API

A Japan-based EC operator was spending 3–4 hours daily on manual data entry across order, inventory, and shipping systems — three tools with no sync between them.

↳ Manual order processing significantly reduced. 2-layer inventory automated in real time.

AI Invoice Processing — Auto-Extract from LINE or Google Drive

Back-office teams manually keyed invoice data into accounting systems. AMCOLAB built an AI extraction pipeline supporting two input paths: LINE chatbot photo upload or Google Drive file drop.

↳ Invoice data entry significantly reduced. High-accuracy extraction from photos and scans, including low-quality images.

Platform Development · Real Estate · Video

Real Estate Platform with Short Video and Livestream Open Houses

Property agencies were spending significant time on 1-on-1 in-person showings for buyers not yet ready to commit. The client needed to reach multiple buyers simultaneously before physical visits.

↳ Early-stage buyer evaluation shifted from individual in-person showings to video-first remote discovery.

AI Recruitment Platform with Compatibility Scoring

A recruitment platform needed to surface workplace compatibility — working style, communication preference, cultural fit — not just keyword matches. Standard job board search was missing the signals that matter most in Japan.

↳ Employers received AI-ranked candidate shortlists based on multi-dimensional compatibility, not resume keywords.

Business Systems · Manufacturing · AI

Auto-Generate Product Manuals at Scale — 30,000+ Templates

A manufacturer needed user manuals for tens of thousands of product models. Manual production was completely impractical at catalog scale — each product had unique specs but followed standardized documentation formats.

↳ Manual production per product: hours of writing → near-instant PDF generation. Full catalog coverage achieved.

Real-Time Food Quality Inspection via Computer Vision

A food company needed consistent quality control on a production line. Human visual inspection was subjective, inconsistent between shifts, and could not scale to production volume.

↳ Every dish evaluated against 10 objective criteria in real time. Zero variation between inspectors or shifts.

Business Systems · DX · Professional Services

Funeral Operations DX — Excel and Paper to Centralized System

A funeral services operator managed every stage — intake, scheduling, supplier coordination, billing — through Excel and paper. Information was siloed to individuals.

↳ Excel and paper removed from core workflow. All staff working from a single shared record per service event.

Platform Development · B2B Marketplace

B2B Equipment Maintenance Matching Platform with Escrow Payment

Equipment owners in agriculture and construction could not find reliable maintenance specialists. Service providers had no channel to reach B2B clients.

↳ Trust barrier resolved via escrow mechanism. Full transaction lifecycle — request, match, escrow, completion, payout — handled in-platform.
