Inventory Basics for MVP Stores: Simple Stock Management That Works
Over-engineering inventory is a common MVP trap. You don't need warehouse management software — you need to know if a product is in stock and prevent overselling. Here's the simple approach.
MVP Inventory Schema
Product:
id
title
price
stockQuantity (integer, default: 0)
trackInventory (boolean, default: true)
lowStockThreshold (integer, default: 5)
That's it. No warehouse locations, no batch numbers, no lot tracking. Just a count.
Core Operations
Decrement on Purchase
When an order is placed, decrement stockQuantity for each item. Use a database transaction to prevent race conditions (two buyers purchasing the last item simultaneously).
Display Stock Status
| Stock Level | Display | UX |
|---|---|---|
| > lowStockThreshold | "In Stock" (green) | Normal add-to-cart |
| 1-5 (at/below threshold) | "Only X left" (orange) | Creates urgency |
| 0 | "Out of Stock" (red) | Disable add-to-cart, show "Notify Me" |
Prevent Overselling
Check stock before creating a checkout session. If stock changed between cart and checkout, show a clear error: "Sorry, [Product] is now out of stock. It's been removed from your cart."
