What Is PIM? Product Information Management Explained

In short: a PIM (product information management system) is the single place where you write, complete and translate product data before sending it automatically to your website, marketplaces and catalogs. It pays off when the number of values to keep up to date (products × attributes × channels) outgrows what a spreadsheet can handle, often a few tens of thousands of cells.

The topic sounds like something for big retailers. In reality, it concerns any business that sells the same product in several places: a manufacturer supplying dealers, an online store that also sells on Amazon and Walmart Marketplace, a wholesaler that prints an annual catalog.

What is PIM, in practice?

A PIM does three things:

1. Centralize: each product has one record, with its attributes (dimensions, material, compatibility), its copy, its images and its documents (manuals, safety data sheets).
2. Enrich: different people complete the record. Engineering fills in specifications, marketing writes the copy, a translator produces the Spanish or French version. The PIM shows how complete each record is, channel by channel.
3. Distribute: the PIM sends each channel the fields it expects, in the format it expects. Your website gets a long description, a marketplace gets a 150-character title, a dealer gets a spreadsheet in its own layout.

The difference from a shared spreadsheet comes down to one word: rules. A PIM rejects a malformed GTIN, flags a missing translation, and blocks a record from going out incomplete.

PIM vs ERP, DAM and CMS: who does what?

Tool	Role	Example data
ERP	Operations: purchasing, inventory, orders, invoicing	Purchase cost, stock level, internal SKU
PIM	Sales information, enriched and translated	Description, attributes, selling points, GTIN
DAM	Media library	High-resolution photos, videos, logos
CMS or ecommerce platform	Display on the website	Layout, cart, checkout

Many PIMs include enough media management for a small business. A separate DAM (digital asset management) is only worth it with large volumes of visuals or a dedicated creative team.

When does a PIM start to pay off?

The number of products alone does not settle it. The useful calculation multiplies three factors:

number of products × number of attributes × number of channels (or languages)

Take a business selling 800 hardware SKUs, described by 30 attributes, on its own site, Amazon, Walmart Marketplace and a dealer catalog. That is 800 × 30 × 4 = 96,000 values to keep consistent. Add a Spanish version for US Hispanic customers or a French one for Canada, and the volume of text to manage doubles.

At that level, every change (a new standard, a supplier that swaps a component) has to be copied by hand into four files, with a risk of error each time. The warning signs are easy to spot:

• a dealer tells you a specification on their site is wrong;
• a marketplace rejects listings for a missing attribute;
• launching a product line takes longer in data entry than in design;
• nobody knows which version of the product file is the right one.

By contrast, a store with 150 products sold on a single site does not need a PIM: its ecommerce platform is enough.

What should a well-structured product record contain?

Your sales channels set the requirements, and those requirements shape your data model. Google Merchant Center’s product data specification, which feeds Shopping ads and free listings, is a good example:

• always required: ID, title, description, link, image link, availability and price, plus brand for new products (except movies, books and music recordings);
• title limited to 150 characters, description to 5,000 characters;
• GTIN (the UPC or EAN barcode number) strongly recommended when the product has one; Google says an incorrect GTIN gets the product disapproved, and “when in doubt don’t provide this attribute”;
• MPN (manufacturer part number) required when the product has no manufacturer-assigned GTIN.

A well-configured PIM checks those rules before sending. It also helps with search: complete, unique and consistent product pages avoid the duplicate content that shows up among the most common SEO mistakes on ecommerce sites.

Why does the EU digital product passport matter outside Europe?

If you sell into the European Union, even from the US or the UK, a new obligation is taking shape. The EU’s Ecodesign for Sustainable Products Regulation (Regulation (EU) 2024/1781) has been in force since July 18, 2024. It creates the digital product passport, which the European Commission describes as “a digital identity card for products, components, and materials.”

Its content will be set category by category through delegated acts. It can cover technical performance, materials and their origin, repairability, recycling and environmental impact. The Commission says customs authorities will be able to run automatic checks on the existence and authenticity of the passports of imported products.

For a business affected, that information will have to exist somewhere, up to date and tied to each SKU. A structured PIM is the natural place to keep it. If your products fall into the first categories targeted, planning your data structure now costs far less than rebuilding it in a hurry. There is no equivalent federal requirement in the US today, so a business selling only domestically can treat this as a watch item rather than a deadline.

How do you choose and roll out a PIM?

1. List your channels and what each one requires (fields, formats, languages). That list is your requirements document.
2. Define a data model: product families, attributes per family, required attributes per channel. This is the longest and most useful step.
3. Choose between open source and SaaS. Akeneo presents its Community Edition as a free, open-source PIM for small and medium-sized businesses. The software costs nothing, but hosting, updates and connectors require a partner or in-house skills. Paid SaaS products take that technical layer off your hands.
4. Check the connectors to your ecommerce platform, your ERP and your marketplaces. A missing connector gets paid for in development time.
5. Clean before importing. Duplicates, inconsistent units (inches and millimeters mixed), copy pasted from the supplier: fix them at the source.
6. Start with one product family, measure the time saved, then expand.

On the organizational side, name one person responsible for product data. Without that owner, a PIM turns back into an expensive spreadsheet within a year. If your customer records live in a separate tool, make sure everyone knows which system owns which data; our guide to what a CRM is explains where customer data belongs.

What mistakes should you avoid with a PIM?

• Choosing the tool before the data model. The software will not decide for you which attributes matter.
• Copying supplier descriptions. They are identical at every retailer and add nothing for search.
• Forgetting languages. If international sales are on the roadmap, structure translatable fields from day one.
• Neglecting media. Badly named, oversized images hurt site speed and your Core Web Vitals as much as they hurt product page quality.
• Underestimating launches. A PIM mostly speeds up a product launch: that is where its return on investment shows.

A PIM does not sell anything by itself. It makes sure that what is written about your products is accurate, complete and identical everywhere, which becomes a requirement as channels and regulations multiply.
