You have 2-3 stores/warehouses in different locations. Each warehouse has its own staff, its own inventory. And you are managing it all with Excel + Zalo - warehouse staff report inventory via messages, you update them into an Excel file. When a customer asks "Do you have this in stock?" - you have to text the warehouse staff → wait for a reply → then reply to the customer.
Challenges of Multi-Branch Warehouse Management
| Problem | Consequence |
|---|---|
| Each warehouse has its own Excel file | Cannot know total inventory |
| Updates are not real-time | Item is out of stock, but the file still shows "in stock" |
| Data entry errors | Discrepancies during month-end inventory count |
| Unknown cost price | Purchasing items in multiple batches at different prices → cannot know true profit |
| Warehouse transfers on paper | Lost inventory during transfers between warehouses |
| Cannot issue e-invoices promptly | Violation of Decree 123 |
GTG CRM — Unified System for Warehouse Management + Invoices
Unlike simple warehouse software, GTG CRM connects inventory with e-invoices and orders — especially suitable for sole proprietorships needing to comply with Decree 123.
1. Manage Multiple Warehouses from 1 Dashboard
Create and manage multiple warehouses:
| Warehouse | Location | Person in charge |
|---|---|---|
| Main Warehouse | 123 Nguyen Trai, Dist. 1 | Mr. Minh |
| Branch Warehouse 1 | 456 Le Loi, Dist. 3 | Ms. Hoa |
| Branch Warehouse 2 | 789 CMT8, Binh Duong | Mr. Tuan |
All displayed on 1 dashboard:
- Inventory per warehouse
- Total inventory
- Slow-moving stock
- Low stock items
2. Tracked Warehouse Transfers
When you need to transfer goods from warehouse A to warehouse B:
```
Create a transfer order
→ Warehouse A: Dispense 100 units of Product X
→ Shipping
→ Warehouse B: Receive 100 units of Product X
→ Confirm receipt
```
- Full tracking: who created, when, how much
- If shortage upon receipt → system records discrepancy
- Never "lose inventory in transit" unknowingly
3. Connect Warehouse → E-Invoice
This is the key differentiator from typical warehouse software:
```
Customer buys at the store
↓
Create order → Select dispense from Branch Warehouse 1
↓
Inventory at Branch Warehouse 1 automatically decreases
↓ (simultaneously)
E-invoice is automatically generated
↓
Sign → Send to Tax Department → Email to customer
```
1 action = inventory dispatch + e-invoice creation + revenue recording.
4. Inventory Inward + Cost Price Calculation
When receiving goods from a supplier:
```
Create an inward goods receipt:
- Supplier: ABC Corp
- Product: 200 units × 50,000đ
- Receiving warehouse: Main Warehouse
↓
Inventory increases + FIFO cost price updated
↓ (optional)
Create purchase invoice (incoming e-invoice)
```
5. Reports for Sole Proprietorships
Simple, easy-to-understand reports - no accountant needed:
| Report | Content |
|---|---|
| Current Inventory | Quantity + value of inventory per warehouse |
| Inward - Outward | Summary of inward/outward movements by day/month |
| Product Profit/Loss | Selling price - Cost price = Profit, per product |
| Slow-Moving Stock | Items not sold for > 30/60/90 days |
| Revenue | Total revenue by warehouse, by branch |
Comparison: Excel vs GTG CRM
| Criteria | Excel | GTG CRM |
|---|---|---|
| Multi-Warehouse | Multiple files, hard to consolidate | 1 dashboard for all |
| Real-time | Manual updates | Automatic upon transaction |
| Warehouse Transfers | Paper/Zalo records | Electronic transfer orders |
| FIFO Cost Price | Manual calculation (prone to errors) | Automatic and accurate |
| E-Invoices | Requires separate software | Built-in integration |
| Low Stock Alerts | No | Automatic |
| Errors | 10-20% | < 1% |
| Cost | 0đ (but time-consuming) | From 199K/month (saves time) |
Who is it suitable for?
| Business Type | Example |
|---|---|
| Retail Sole Proprietorships with Multiple Stores | Convenience store chains, fashion shops with 2-3 branches |
| Distribution Agents | Central warehouse + agent warehouses |
| Small-Scale Manufacturing | Raw material warehouse + finished goods warehouse |
| E-commerce Sellers | FBM warehouse + dropship warehouse |
| F&B Chains | Raw material inventory for each branch |

Conclusion
When a business has multiple warehouses or branches, managing with Excel can easily lead to inventory discrepancies, time-consuming checks, and difficulty in controlling actual profits. A centralized warehouse management system helps update inventory in real-time, clearly track inward-outward-transfer movements, and connect directly with orders and invoices. With GTG CRM, sole proprietorships can manage all their inventory, revenue, and invoices within a single platform, leading to more accurate and professional operations.
