Running a reselling business isn’t just about sourcing and listing—it’s about systems. Without organized inventory and accurate numbers, it’s easy to feel overwhelmed or lose track of what’s profitable.
From 2024 to now, I’ve experimented with three spreadsheet setups and multiple storage solutions. Each iteration taught me something, and today I finally have a system that works—and keeps my numbers accurate. That alone has been a game-changer.
The Evolution of My Systems
1. Brand-Based Storage
Initially, I stored items strictly by brand. While logical at first, it became chaotic as my inventory grew. Searching for specific items took longer than necessary, and my spreadsheets often didn’t match reality.
2. SKU System
Next, I tried a SKU-based system, assigning a unique code to every item. While this helped with tracking, it became too time-consuming to maintain, especially with hundreds of listings.
3. Category + Subcategory Organization
Finally, I moved to category-based storage, which has been my most functional system so far. I now separate inventory into male, female, kids (girl/boy), and shoes, with further subdivisions:
-
Men’s bins:
-
Tops
-
Bottoms (I don’t sell a lot of men’s items, so two bins work for now)
-
-
Women’s bins:
-
Jeans
-
Shorts & skirts
-
Tops
-
Dresses
-
Dress clothes
-
Athletic wear
-
This structure, combined with my spreadsheets, makes it easy to pull items, track sales, and maintain accurate inventory counts.
What I’m Changing for 2026
Even with a system that works, there’s always room to improve—especially for small or miscellaneous items like ties, toys, or perfumes.
Here’s what I’ve started implementing:
-
Small stacking storage for items like ties, toys, and perfumes
-
Continuing to add and organize small items as I source them
-
Keeping the main category-based system for clothing and shoes, while fine-tuning where small items live
These adjustments will make shipping prep faster, reduce mistakes, and help me maintain efficiency as my business grows.
Why Systems Matter
Good systems save time, reduce errors, and keep you focused. By maintaining accurate numbers and organized storage, I can focus on:
-
Sourcing smarter
-
Listing consistently
-
Making data-driven decisions
The goal for 2026 is less chaos, more efficiency, and staying proactive instead of reactive.
The right system evolves with your business. What worked in 2024 might not work in 2026, and that’s okay. Taking the time to experiment, adjust, and maintain accurate numbers has been critical to keeping my reselling business running smoothly.
Small changes—like stacking bins for small items—have a big impact on organization and efficiency. My detailed bin system for men, women, kids, and shoes ensures I can find items quickly, pull for orders without stress, and stay on top of my inventory counts.
