How to Build a Product Catalog for Your Online Store
A messy catalog is the number one reason new stores fail to sell.
Of all the problems I see in new stores, the most common one is the catalog. Products without descriptions, blurry photos, prices that do not add up, categories that make no sense. That scares customers away before they even reach the cart.
What Information Does Each Product Need?
At a minimum, every product in your store should have:
- A clear name. "White cotton basic tee" is better than "Tee 001" or "NEW COLLECTION!!!"
- A useful description. What it is, what it is made of, what it is for, sizing or measurements. Do not just copy-paste the supplier's spec sheet.
- A price. Make sure it includes any applicable taxes if that is the standard in your market (in many Latin American countries, the final consumer price must include VAT).
- Photos. At least 2-3 photos per product. White or neutral background. The product should be clearly visible.
- Stock. If you do not have unlimited inventory, show real availability.
- Variants. If it comes in different sizes or colors, each variant should be properly set up.
How Do I Organize Categories?
Category structure depends on your business, but there are rules that always apply:
| Good practice | Common mistake |
|---|---|
| 5-8 main categories max | 20 categories with 2 products each |
| Descriptive names ("T-Shirts," "Accessories") | Vague names ("Products," "Other") |
| Subcategories only when there is enough volume | Empty subcategories |
| A dedicated sale or featured section | Everything mixed up with no order |
Example for a clothing store:
- T-Shirts
- Pants
- Accessories
- Sale
That is enough to get started. Do not invent categories you do not need.
How Many Products Do I Need to Launch?
There is no magic number, but fewer than 10 looks empty and more than 100 is hard to manage at the beginning. Between 15 and 40 products is a good range for launch.
What matters is not the quantity but the quality of each listing. I would rather see a store with 20 well-presented products than one with 200 copy-pasted listings with no photos.
The Never-Ending Spreadsheet Trap
Many entrepreneurs spend weeks building a massive spreadsheet with all their products before uploading anything. The problem is that spreadsheet never gets finished. There is always a missing detail, a missing photo, a missing price.
Better approach: upload the first 10-15 products with all their information complete. Publish the store. Keep adding products afterward.
The store does not need to be "complete" to go live. It needs to be functional. Someone should be able to visit, see a product, understand what it is, and buy it. The rest gets built over time.
If your catalog has been sitting in a spreadsheet for weeks without progress, it is time to upload it to the store and stop polishing in private.
