Inventory Management for Small Ecommerce Sellers: Simple Systems That Work

## Why Inventory Management Breaks Most Small Sellers

Overselling (taking orders you can't fulfill) is a seller account killer. It leads to:

Automatic order cancellations

Seller rating drops

Account suspension on repeat

Most small sellers oversell because they have no inventory system.

Level 1: The Google Sheets Tracker (Free, Works for 0–100 Orders/Day)

Create a simple sheet with:

Column A: SKU

Column B: Product Name

Column C: Current Stock

Column D: Reserved (order placed but not shipped)

Column E: Available = C - D

Update daily. Manually deduct shipped quantities. Free template available: Search "Ecommerce Inventory Google Sheets Template"

Level 2: Mobile Apps (₹0–₹500/month, 100–300 Orders/Day)

Apps like Vyapar or OkCredit have simple stock management features. Add stock when you receive inventory, subtract when you ship.

Level 3: Multichannel Software (₹2,000–₹10,000/month, 300+ Orders/Day)

Unicommerce or EasyEcom sync inventory across all platforms in real time. When a Meesho order comes in, it deducts from Flipkart and Amazon stock simultaneously.

Reorder Point Formula

Reorder Point = (Average Daily Sales × Lead Time in Days) + Safety Stock

Example: You sell 20 units/day, supplier takes 5 days to deliver, keep 3 days safety stock: Reorder Point = (20 × 5) + (20 × 3) = 160 units

Connecting Inventory to Picklist

MyInstantTool's picklist shows exactly how many units of each SKU you need to pack. Cross-reference this with your stock levels daily to spot potential stockouts before they happen.
