What can our suppliers send?

Any CSV file, in whatever layout, order, size and language the supplier uses, with their own column names. Image links in the file come in as product images, and HTML in a cell stays HTML.

Do our suppliers need to change anything?

No. Your team uploads the file the supplier already sends, in the layout they already use.

How do files about the same product come together?

On an identifier. Cernel uses the column that holds the SKU, GTIN, EAN, MPN or your own identifier, and each row lands on the product it belongs to, whenever the file arrives.

What happens when the same supplier sends the next file?

It goes in the same way. Use the earlier upload as the template: columns are matched by name, so a column the supplier has moved keeps its place.

Does anything change in our catalogue before we approve it?

No. Before an upload runs, you see how many products will be created and updated, and nothing is written until you start it. After that, you choose which enriched values go live automatically and which get a review step.

Supplier data onboarding

Your supplier sends a code and a colour. You need a complete product.

Upload the supplier's file as it is. Cernel joins it to your products and fills in the rest, so your team checks products instead of typing them in.

- One import template per supplier
With Cernel
The supplier's file, as it is, turned into your products
Cernel works out what each column holds, and the supplier's next file goes in the same way.
In pieces

- Your inbox
- A tracking sheet
With Cernel
Every file joins onto the product it belongs to
Rows land on your products by SKU, GTIN, EAN or your own identifier, whenever the file arrives.
Gaps
Instead of
Sending missing fields back to product managers and waiting weeks
- Emails
- Brand sites in twenty tabs
With Cernel
Empty fields filled from your data and the maker's own pages
An agent looks the value up on the maker's page by EAN or name, on the sites you allow.
Drift
Instead of
Marine, Navy blue, Dark navy: every supplier names the same colour its own way
- A value list in a spreadsheet
- Clean-up rounds
With Cernel
What suppliers send, converted into the values your team chose
Cernel picks from your own option lists, so every product reads the same and filters stay clean.

How it works

From the supplier's file to a finished product, in five steps.

What happens to one supplier file in Cernel. Pick a step, or let it play.

Drop in the file the supplier sent, in their layout and their language. Your suppliers change nothing.
Cernel works out what each column holds, whatever the supplier calls it: the product code, the name, the colour, the EAN, the image links. The supplier's next file goes in the same way.
Each row lands on the product it belongs to, by EAN, GTIN or SKU. Products you have are updated and new ones are created, and you see both counts before anything changes.
Agents turn the supplier's words into your own values, find missing details on the maker's page and write titles and descriptions in your voice.
You choose which values go live automatically and which get a review step; review steps check every value and only ask a person when something fails or needs a decision. Approved values go to your PIM or your shop.

The price list in week one, the data sheet in week three, the image links in week five. One product.

Supplier data rarely arrives in one go. Upload each file as it comes, in whatever layout the supplier uses: Cernel joins it to the same product by its EAN, and the product fills up as the data arrives.

After the import

Products in your structure, filled, checked and sent back.

Sorted on arrival
Every new product lands in its category as it comes in, and each value keeps where it came from: the supplier's file, an agent or a person on your team.
Product categorization
Filled and checked
New products are enriched the moment they arrive: attributes, titles and descriptions, and the values an agent finds on the maker's page. You choose which values go live automatically and which get a review step; review steps check every value and only ask a person when something fails or needs a decision.
Product data enrichment
Back to your systems
Approved values go back to your PIM or your shop, typically within a minute. Any other system takes them as a file in its own columns or through the API.
