How to Prepare a Product Catalogue Before Building an E-commerce Website

A catalogue is more than a list of products

Before an e-commerce website is designed, the catalogue gives the project a practical structure. It helps define what will be presented, how products will be grouped and which information a customer needs before placing an order.

The task is not to write every product page in its final form from the start. It is to gather and validate the information that will shape the journey, pages and day-to-day organisation of the store.

Choose the products for the initial online catalogue

A business can start with the products it genuinely plans to offer online. This initial scope should represent useful cases: straightforward products, products with variants or specific selling rules, and categories that help visitors find their way.

Prepare a representative first catalogue

A representative initial catalogue is often more useful than waiting for a supposedly perfect version. It reveals missing information and decisions to make before the website structure is defined.

The aim is not to set a fixed product count. It is to gather examples that expose the real cases in the business and the rules the future journey needs to account for.

Organise categories and subcategories

Categories should help people find a product type without knowing every reference. They can reflect a family, use, collection or another way of grouping that customers and the team already understand.

A subcategory is useful when it creates a clear distinction. When two groups describe almost the same thing, it is better to clarify the structure before reproducing it in navigation.

Prepare the information for every product

For every product, the business should prepare or validate the elements needed to present it clearly: name, internal reference where it is used, description, price, selling unit, availability and characteristics that matter for that product.

Images used in the catalogue should be approved and supplied by the business. They should match the product shown and remain consistent with the information customers see on the page.

• Name and reference where the business uses one
• Useful description and characteristics
• Approved product images supplied by the business
• Validated price and selling unit
• Availability and information useful for a decision

Identify variants and selling rules

A variant may be a size, colour, format, bundle or another difference genuinely offered for purchase. The business should clarify what changes the price, availability or information shown so the product does not create uncertainty when an order is placed.

It is also useful to identify the person who validates source information. That responsibility prevents provisional data from appearing as final information in the future catalogue.

Connect catalogue information to the future order journey

The catalogue affects the questions product pages need to answer. The business can document delivery areas that need defining, how orders will be confirmed, who updates stock and the questions customers regularly ask.

These elements are not a guide to payment or delivery providers. They clarify operational choices that need to remain consistent with the chosen ordering journey.

Checklist before handing over the catalogue

• Initial product scope defined
• Main categories identified
• Names and references available
• Approved product descriptions and images available
• Prices and selling units validated
• Variants and rules affecting price or availability identified
• Stock and availability responsibility clarified
• Questions about delivery areas and order confirmation documented
• Person responsible for catalogue validation identified

When a catalogue needs a complete e-commerce journey

A catalogue can simply present an offer, or become the starting point for a journey where visitors select products and place orders. The difference depends on how the business wants to sell and organise its operations.

When a project needs a catalogue, product pages and a coherent ordering journey, the discussion can focus on an e-commerce scope that fits the information already prepared.

Move from a catalogue to a scoped e-commerce project

A prepared catalogue makes it possible to discuss a project on a practical basis: products, information to display, rules to clarify and the journey to build. It does not replace scoping, but it makes design decisions easier to understand.
