Upload Products

Upload products lets vendors add product data from a file instead of creating every product manually. This is useful when you already have a price list, product catalog, or inventory export.

What is product upload?

Product upload is the process of importing product data into Mathership from a file. Vendors can use it to create or update products in their vendor catalog. Typical uploaded product data includes:
  • Product name
  • Product number
  • Packaging
  • Stock
  • Price
  • Product description

Who can upload products?

Product uploads are available to vendor users. A vendor can only upload products for their own vendor company.
Vendors cannot upload products into another vendor company.

Supported upload format

Product upload is based on a CSV file. The file should contain product data in columns. Mathership reads the file and uses a field mapping to understand which column belongs to which product field.
The exact CSV delimiter can vary. Mathership can detect common delimiters such as semicolon, comma, tab, or space.

Required fields

The upload requires certain fields so products can be created correctly.
FieldRequiredMeaning
Product nameYesName of the product
PackagingYesPackaging or order unit shown to customers
Product numberUsually yes for vendorsVendor article number or product identifier

Optional fields

Optional fields can improve the product catalog.
FieldMeaning
StockCurrent stock value
PriceProduct price
Product descriptionAdditional product information
If stock or price is missing, Mathership can save the value as 0.

Field mapping

Before importing the file, Mathership needs to know which CSV column matches which product field. Example:
Product fieldCSV column
Product nameArtikelname
Product numberArtikelnummer
PackagingGebinde
StockLagerbestand
PricePreis
Product descriptionBeschreibung
This mapping helps Mathership import files with different column names.

Product numbers

Product numbers help identify products during upload. If a product number already exists for the vendor company, the existing product can be updated. If no matching product number exists, a new product can be created.
Product numbers are especially important when using uploads to update an existing catalog.

Products without product numbers

If no product number is available, Mathership can still create a product using a fallback product number. This is useful for simple catalogs, but it can make future updates less precise.
For reliable future uploads, use stable product numbers whenever possible.

Updating existing products

Product upload can update existing products when the product number matches an existing product in the same vendor company. This can update fields such as:
  • Product name
  • Packaging
  • Stock
  • Price
  • Product description

Creating new products

If the uploaded product does not match an existing product number, Mathership can create a new product. The new product is assigned to the vendor company used for the upload.

Upload result

After the upload, Mathership can return an import result. The result can include:
Result fieldMeaning
Success countNumber of rows successfully imported
ErrorsRows that could not be imported
Row numberThe row where an error happened
Error messageWhat went wrong

Partial success

Product upload can partially succeed. This means some rows are imported, while other rows contain errors.
A few invalid rows do not necessarily prevent all other rows from being imported.

Example: Simple product upload

A vendor uploads a CSV file with these columns:
ArtikelnummerArtikelnameGebindePreis
1001Tomato juiceCrate 12 x 1 L18.50
1002Orange juiceCrate 12 x 1 L19.20
The vendor maps:
Product fieldCSV column
Product numberArtikelnummer
Product nameArtikelname
PackagingGebinde
PricePreis
Mathership can then create or update the products.

Example: Upload with stock

ArtikelnummerArtikelnameGebindeLagerbestand
2001Mineral waterCrate 12 x 0.75 L50
2002Apple spritzerCrate 12 x 1 L35
The stock value can be saved with the product and used in the vendor catalog.

Example: Missing price

If a product row has no price, Mathership can still import the product.
ArtikelnummerArtikelnameGebindePreis
3001Seasonal productBox
The product can be created with a price value of 0.

Common problems

Upload file is missing

Check that a file was selected before starting the upload.

Mapping is missing

Check that all required product fields are mapped to CSV columns.

Required value is empty

Check that required columns contain values in every row. Required fields usually include product name and packaging.

Product number is missing

Use stable product numbers whenever possible. Without product numbers, future updates can be harder to match.

Price or stock is not imported correctly

Check that price and stock values use a clear number format. Avoid text such as currency symbols, units, or extra comments in numeric columns.

Wrong products were updated

Check whether product numbers are reused incorrectly in the CSV file. Product numbers should identify one product clearly within the vendor company.

Best practices

Clean the file before uploading

Remove empty rows, old test rows, duplicate products, and unnecessary columns.

Use stable product numbers

Stable product numbers make future catalog updates safer.

Map fields carefully

Review the mapping before starting the upload.

Start with a small test file

Upload a small sample first if the catalog is large or the file structure is new.

Review errors after upload

Check failed rows and correct them before uploading again.

Review the catalog after upload

Open the product list and confirm that names, packaging, prices, and stock values look correct.

Adding Products

Add products manually to the vendor catalog.

Bulk Product Upload

Import or update many products from a CSV file.

Edit Products

Update product data after upload.

Product Images

Add or manage product images.

Availability

Mark uploaded products as available or not available.

Packaging Levels

Define product packaging structures.
