Top 10 Inventory KPIs Every Recommerce Brand Should Track

In recommerce, data is everything. Whether you're running a second-hand store, a digital consignment platform, or a buy-back program, your success depends on how well you manage and measure your inventory.

Here are the top 10 inventory KPIs that every resale business should track in 2025:

1 Sell-through rate

What percentage of your listed items actually sell?

2 Average days on shelf

How long do items sit before selling?

3 Return-to-owner ratio

What percent of items are returned unsold?

4 Donation ratio

How many items are never claimed or sold?

5 Initial price vs. sale price variance

Are your pricing strategies working?

6 Category velocity

What categories move the fastest (e.g. sneakers vs. jackets)?

7 Gross margin per item

Are you hitting profit targets by category?

8 High-performer index

Which brands consistently sell fast and high?

9 Shelf time alerts

How many items are trending toward expiration?

10 AI pricing confidence score

How confident is your AI in the suggested price?

Tracking these KPIs in a spreadsheet is possible, but time-consuming. The best way is to use inventory management software built for resale, with built-in analytics dashboards and real-time insights.

The result? Faster decision-making, better sourcing, and higher revenue. Inventory KPIs don’t just help you manage stock. They help you grow.
