What is Selly?
Selly is built for resellers who want a complete picture of their business in one place. Whether you’re flipping sneakers, streetwear, electronics, or collectibles, Selly gives you the tools to stay organized, track every dollar, and grow profitably. Instead of juggling spreadsheets, notes apps, and mental math, Selly centralizes everything — your inventory, your sales, your expenses, and your storefront — in one clean dashboard.Core Features

How Selly Works
Selly is organized around the natural flow of a resale business:Add inventory
When you acquire items, log them in Inventory with the cost you paid, the sizes you have, and the quantity per size. Every unit starts as Unlisted.
List items
When an item goes up for sale on a marketplace, update its status to Listed and enter your asking price. It now appears on your Storefront automatically.
Record sales
When an item sells, log it from the Dashboard with the sale price, platform, and date. The unit is automatically marked as Sold.
Track expenses
Log overhead costs on the Expenses page — shipping supplies, marketplace fees, storage, tools, and anything else that cuts into profit.
Review your numbers
Use the Performance page to analyze revenue, profit, and margins. Use the Dashboard for a real-time snapshot.
Understanding Profit in Selly

- Gross profit = Revenue minus cost of goods sold
- Net profit = Gross profit minus expenses
