PLM (product lifecycle management) manages a product while it's being designed and made. PIM (product information management) manages the information needed to sell it once it's ready. Most brands that design their own products use both, with data passing from PLM to PIM before launch.
Take a skincare brand launching an SPF 30 sunscreen. The formula, ingredient percentages, test results and packaging artwork are worked out in PLM. The product title, description, images and the ingredient list shoppers see are managed in PIM, then sent to the brand's own site and to each retailer.
What is PLM?
PLM software manages a product from first idea to end of life. It holds the data teams need to design and make the product: CAD files or formulas, specifications, bills of materials, supplier and material data, test results and the history of every change.
Its users are the teams building the product, such as R&D, engineering, quality, compliance and sourcing. The goal is to get a product designed and approved for manufacturing, with everyone working from the latest version.
What is PIM?
A PIM holds the information a shopper or a sales channel needs about a product, such as titles, descriptions, attributes, images and channel-specific fields. It collects data from the ERP, the PLM, suppliers and spreadsheets, turns it into one complete record per product, and publishes the right version to each website and marketplace.
Its users are the teams selling the product: ecommerce, merchandising, marketing and channel managers. Our guide to product information management covers how a PIM works in more detail.
What's the difference between PIM and PLM?
PLM covers the product before launch, and PIM covers how it's presented once it's for sale.
| PLM | PIM | |
|---|---|---|
| Purpose | Design and develop products | Describe and sell products |
| Stage | Idea through manufacturing, plus later design changes | Pre-launch through every channel update |
| Main users | R&D, engineering, quality, compliance, sourcing | Ecommerce, merchandising, marketing, channel managers |
| Data it holds | Specs, formulas or CAD files, bills of materials, test results, change history | Titles, descriptions, attributes, images, translations, channel fields |
| Output | An approved product, ready to make | A complete listing for each channel |
| Connects to | CAD and design tools, ERP | ERP, PLM, DAM, ecommerce platforms, marketplaces |
What data moves from PLM to PIM?
Only part of the PLM record is useful to shoppers. The handoff takes the approved technical details and turns them into attributes and copy a customer can read. For the sunscreen, it might look like this:
| In PLM | What reaches the PIM |
|---|---|
| Formula version 4.2, with ingredient percentages | The ingredient list, in the order printed on the label |
| SPF and water resistance test reports | "SPF 30" and "Water resistant (80 minutes)" as attributes and claims |
| Packaging dieline and artwork files | Final pack shots for the product images |
| Fill size and component specs | Size attribute: 50 ml (1.7 fl oz) |
| Change history and earlier formula versions | Nothing. These stay in PLM |
Two things can go wrong at this step. When values are retyped by hand, a listing can end up showing an older formula's details. And claims can drift from the test data, for example copy that says "water resistant" for a product that was never tested for it. Syncing approved fields, and checking claims against the product record before publishing, helps prevent both.
Do you need PIM, PLM or both?
It depends on whether you design the products you sell.
- Brands and manufacturers that design their own products usually need both. PLM runs development, and PIM takes over as launch approaches.
- Retailers and distributors that sell other companies' products usually need a PIM without a PLM. Their product data comes out of each supplier's own development work, as spec sheets, spreadsheets, PDFs and feeds. The job is getting that data into one consistent format.
- Small brands with a handful of products can often run development in documents and shared drives, and add a PLM once formulas, suppliers or regulations get harder to track.
A PIM can hold some lifecycle details, such as a product's launch stage, but it isn't built for formulas, bills of materials, test results or engineering change control. A PLM can store some marketing text, but it isn't built to format and publish content for each sales channel.
How do PIM and PLM work together?
- Decide which system owns each field. Technical values, such as dimensions or SPF, are owned in PLM. Marketing copy, images and channel fields are owned in PIM. Each field is edited in one place only.
- Map PLM fields to PIM attributes. PLM field names are written for engineers. Map them to the attribute names and units your channels use, for example a formula field called "SPF_label" to a shopper-facing "SPF" attribute.
- Sync only approved changes. Send data to the PIM when a change is approved in PLM, so work-in-progress values stay out of live listings.
- Check claims before publishing. Compare marketing claims with the approved test data and certifications before a listing goes live.
Our guide to PIM data governance covers field ownership and validation rules.
What's the difference between PIM and PDM?
PDM (product data management) manages engineering files, such as CAD drawings and technical documents, with version control. It's often part of a PLM, or a lighter tool for smaller design teams. PDM holds the files used to build a product, and PIM holds the information used to sell it. See our guide to product data management.
How does Hypotenuse AI work with your PLM?
Hypotenuse AI is an AI-native PIM. It sits after your PLM, bringing in approved product data and turning it into listings for each channel.
| Handoff step | What Hypotenuse AI does |
|---|---|
| Bring in PLM data | Brings together data from your ERP, PLM, supplier feeds and internal tools in one AI PIM |
| Map fields | Maps incoming fields to your attributes, such as "Material" to "Composition", and normalizes the values |
| Turn specs into copy | Writes titles and descriptions from the product's attributes, in your brand voice, for SEO and AI search |
| Check claims | Checks that claims in your copy are backed by the attributes and certifications on the same product record, and flags banned or missing required terms |
| Products you don't make | Onboards supplier data through one portal, mapping each supplier's format to your attributes |
PIM vs PLM FAQs
Can a PIM replace a PLM?
For product development, no. A PIM can track simple lifecycle details, such as whether a product is ready to launch, but formulas, bills of materials, test results and engineering changes need a PLM.
Is PLM the same as ERP?
No. ERP runs the business side, such as orders, inventory, purchasing and finance. PLM manages product development. Finished product data usually moves from PLM into the ERP and the PIM. See PIM vs ERP.
Do retailers need a PLM?
Retailers that develop their own private-label products often use a PLM for those lines. For products bought from suppliers, the supplier's PLM has done that work, and the retailer needs a PIM to manage the data that arrives.
