The most common mistake new sellers make is creating random or inconsistent SKUs without using a template.
Many users manually type SKUs such as:
book1
goodbook
amazon123
testsku
While these may work for a few listings, they quickly become impossible to manage once inventory grows.
Why This Causes Problems
1. Inventory Becomes Hard to Identify
When SKUs are random, you cannot quickly determine:
The condition of the item
When it was purchased or listed
Which batch it belongs to
Where the item is stored
Example:
SKU | Meaning |
book1 | Unknown |
item123 | Unknown |
VG-2503-0045 | Very Good, March 2025, Item #45 |
A structured SKU tells you important information instantly.
2. Difficult to Find Items in Storage
When orders come in, sellers often need to quickly locate the item.
If the SKU contains useful information like location or batch, the item is easier to find.
Example:
VG-A2-0045
This could mean:
VG = Very Good condition
A2 = Shelf location
0045 = Item number
Without this structure, finding items becomes slower and more frustrating.
3. Hard to Track Sourcing and Profitability
Structured SKUs allow sellers to analyze:
Which supplier performs best
Which batch of inventory sells faster
Where problems are occurring
Without this structure, inventory analysis becomes very difficult.
The Best Way to Avoid This Problem
Use a consistent MSKU template from the start.
A simple and effective template is:
[Condition]-[YYMM]-[Sequence]
Example:
VG-2503-0045
This format:
Keeps SKUs organized
Makes listings easier to manage
Works well with AccelerList auto-SKU generation
Final Tip
The biggest mistake sellers make is waiting too long to implement a template.
Once you already have hundreds or thousands of listings, changing SKUs becomes much harder.
Starting with a structured MSKU template early will save a lot of time and confusion later.
