# Define Your Product Catalog Before Building an Online Store

By Nestack Technologies Pvt Ltd

Adapted and expanded from our article on [e-commerce development with Ruby on Rails](https://nestack.com/ecommerce-with-ruby-on-rails-why-are-online-stores-using-ruby-on-rails-for-quick-development/).

A store's catalog determines what customers can find, what they can order and what the warehouse must send. Decisions about sizes, colors, bundles and stock can affect the software long before anyone chooses a page layout.

Our original article discusses the tradeoff between straightforward product attributes and flexible, more complex catalogs. This guide turns that question into a practical specification for an online store, whether the implementation uses Rails or another platform.

## Start with a representative product sample

Gather real examples before approving the data model. Include a simple item, an item with several options, an unavailable item and any multipack or bundle you intend to sell.

For each example, collect its identifier, description, images, selling unit, price and stock source. Add the information a customer needs to distinguish it from similar products.

A stationery shop might sell individual notebooks, packs of three and notebooks in different sizes. Write down whether a pack has its own stock or is assembled from individual units. Those choices determine how an order changes inventory.

## Separate product families from purchasable variants

Agree what receives its own stock-keeping unit, or SKU. A product family might describe a notebook range, while a particular size and cover color identifies the item a customer receives.

[Shopify's variant documentation](https://help.shopify.com/en/manual/products/variants) illustrates how combinations of options can form variants and how inventory can be managed for each variant. Use this distinction to discuss your own catalog without assuming every possible combination exists.

If blue notebooks come only in A5, the store should not silently create a blue A4 option. Ask the team to demonstrate unavailable combinations and confirm that the selected variant remains clear in the basket and order record.

## Define attributes that support finding products

Separate descriptive copy from fields used for filtering, sorting or comparisons. A sentence saying “large blue notebook” is useful prose, but size and color may also need consistent values in separate fields.

Create a short data dictionary. Specify each field's meaning, format, unit and whether it is required. Record allowed values where consistency matters. Decide how missing information appears, including whether an incomplete product can be published.

Test the proposed filters against the sample catalog. A buyer selecting A5 should see the expected products even if their marketing descriptions use different wording. Check how products with several variants appear in these results.

## Agree the inventory behavior

Identify the system that determines available stock and how changes reach the store. Define when quantities are reserved, reduced or released during the order process.

Use concrete scenarios: two customers request the last notebook, a customer abandons an order, or a warehouse adjustment arrives after an item has entered a basket. Ask what the customer sees at each step and how staff resolve an exception.

For bundles, check whether component availability limits the number of bundles offered. Document any approved backorder behavior, including the message shown before the customer submits an order.

## Make bulk changes predictable

Specify how imports identify existing products and variants. Decide whether an empty spreadsheet cell means “keep the current value” or “clear this field.” Confirm how a renamed product remains connected to its existing records.

Require an import preview with readable errors for invalid rows. For a Rails implementation, the [Active Record validation guide](https://guides.rubyonrails.org/active_record_validations.html) explains data checks before saving and identifies methods that bypass those checks. Ask developers to show that the chosen import path applies the agreed rules.

Test duplicate identifiers, missing required fields and an interrupted import. Agree whether valid rows proceed when other rows fail, and how staff can see exactly what changed.

## Review the catalog through everyday work

Ask a staff member to add a product, correct a description, change availability and retire an item using the proposed administration tools. Include a check that retiring a product preserves the information needed to understand earlier orders.

Then walk through the customer's path from search to order confirmation using the same sample. Compare the selected item, quantity and description with the warehouse's view.

Keep the sample records, field definitions and expected results with the project brief. They give the development team concrete acceptance examples and provide a reference when the range expands.
