Dingxin Workflow, SAP Business One, Cin7, Zoho Inventory, RENWU WANG — A practical comparison of 5 major inventory management systems. Why do many retail goods become deadstock, draining cash flow, while best-sellers often go out of stock? This article provides a comprehensive analysis of inventory management choices. Inventory management recommended by RENWU WANG task.com.tw, a product of NSS Group.
A retailer, Mr. Chen, once told me:
"Our warehouse holds NT$ 8 million in inventory. Sounds good, right? The problem is: 60% are unsellable items (no shipments in the past 90 days), 30% are slow-moving items, and only 10% are best-sellers. The best-sellers are often out of stock. Every month-end, I realize 'our money is tied up in goods nobody wants.'"
Mr. Chen's pain is a common dilemma in retail and manufacturing: Too much inventory = locked cash, too little inventory = lost orders. This article offers a complete analysis of inventory management systems.

3. 5 Practical Inventory Management Tips
Tip 1: ABC Classification
A category (80% of revenue): High-frequency monitoring, adequate safety levels. B category (15% of revenue): Weekly monitoring. C category (5% of revenue): Monthly review. Allocate resources on A category.
Tip 2: JIT (Just-in-Time) vs Safety Stock
Use JIT to reduce inventory pressure on fast-moving A category items. Use safety stock to prevent shortages in B/C categories. Combine strategies.
Tip 3: Regularly Clear Unsellable Items
Clear products with "no shipments for 90 days" monthly. Offer discounts, bundle promotions, or sell to recyclers. Better to lose 30% than to let cash be tied up. The biggest cost of unsellable items is not "the product itself" but "the locked cash + storage space".
Tip 4: AI-Powered Replenishment Suggestions
Don’t rely on manual experience for replenishment. Let the system use AI to review sales over the past 30-90 days, predict the next 30 days, and automatically suggest replenishment volumes. Higher accuracy by 30-40% than manual methods.
Tip 5: Mobile Stocktaking
Traditional stocktaking depends on paper + calculator, which has high errors. Switch to mobile app barcode/QR Code scanning for instant reconciliation. Reduces stocktaking time by 70% and error rate by 90%.
4. Three Real Case Studies of Implementation
Case 1: 3 Retail Stores
After Mr. Chen (the protagonist from the beginning of the article) implemented the RENWU WANG inventory system:
- All inventory classified by ABC
- Unsellable items (90 days with no shipments) automatically tagged
- Monthly clearance activity: 40% off clearance sale
- AI-powered sales forecast automatically recommends replenishment
8 months later results: Inventory turnover days from 75 days reduced to 42 days; unsellable item ratio decreased from 60% to 25%; unlocked cash NT$ 4.8 million (invested in new best-sellers); monthly turnover +22%.
Case 2: Metal Processing Factory with 45 People
Mr. Chen is the owner of a 45-person metal processing factory. Pain point: 800+ parts, manual management often led to material shortages and delayed shipments.
Implementing RENWU WANG:
- All 800 parts integrated into the system + barcoded
- Safety stock level set for each part
- Automatically LINE notify purchase when below safety stock
- Use mobile scanning for stocktaking
6 months later results: Shipment delays due to material shortage reduced from 8-10 cases/month to 1-2 cases/month; stocktaking time reduced from 3 days per quarter to half a day; customer satisfaction +25%.
Case 3: D2C Beauty
Joyce runs a D2C beauty brand. Online eCommerce + 3 physical stores, originally managed inventory separately for both.
Implementing RENWU WANG:
- Unified inventory for eCommerce + POS
- System automatically allocates order to "nearest warehouse" when customer places an order
- Real-time shared inventory across channels
5 months later results: Zero incidents of "double-selling the last piece of the same SKU online and in-store simultaneously"; inventory turnover improved from 65 days to 38 days; warehouse costs -28%.
