Platform Distribution by Business Size

Mistake #1: Separate Stock Management Per Platform

Problem Details

73% of businesses reserve separate stock for each platform. This approach:

❌ EXAMPLE SCENARIO:
Total Stock: 100 units
├── Trendyol: 35 units
├── Hepsiburada: 30 units
├── Amazon: 20 units
└── Own website: 15 units

END OF DAY:
├── Trendyol: 32 sales → 3 units left (out of stock mode)
├── Hepsiburada: 8 sales → 22 units unused
├── Amazon: 5 sales → 15 units unused
└── Own website: 2 sales → 13 units unused

RESULT:
├── Total sales: 47 units
├── Remaining stock: 53 units
└── Idle inventory: 50 units (94% idle!)

Cost Analysis

Result: Potential for +378,000₺ additional revenue per month!

Mistake #2: Manual Order Transfers

Problem Details

68% of businesses still manually check and transfer orders from each platform.

Manual Process Analysis

⏱️ DAILY ROUTINE (3 Platforms):
├── 09:00 - Trendyol check: 45 min
│   ├── 120 orders x 20 sec = 40 min
│   └── Platform navigation: 5 min
├── 10:00 - Hepsiburada check: 30 min
│   ├── 80 orders x 20 sec = 27 min
│   └── Platform navigation: 3 min
├── 10:45 - Amazon check: 20 min
│   ├── 50 orders x 20 sec = 17 min
│   └── Platform navigation: 3 min
└── 11:15 - Own website: 15 min
    ├── 30 orders x 25 sec = 12.5 min
    └── Verification: 2.5 min

TOTAL: 110 min/day = 1.83 hours/day
MONTHLY: 55 hours = ~1.5 staff cost
