Stock Update File Specifications

The stock file sent from the stores have certain requirements and they are listed in the following sections.



The only allowed encodings are UTF-8 / UTF-8-SIG and UTF-16.

What is encoding?


Comma Seperated Value (CSV)

The only allowed stock update file format is CSV and:

  • Must use semi-colons (;) as field separator.
  • Each row must contain both the price and the stock for a given article, even if only the stock or only the price has been changed. There is no wildcard that can be used to ignore either of the fields and it is not possible to skip or provide an empty value for individual rows.
  • CHAR-formatted fields need to be enclosed by double quotes in the CSV-file

File size

10 MB size limit

Please note that the size of a single stock file MUST NOT exceed 10485760 bytes (10 MB). If the stock file is bigger, it must be split in separate CSV files. The file names should be unique, e.g. 20201202T1130-store1.csv, 20201202T1230-store2.csv

Stock Update Requirements


  • For fastest possible stock updates, separate stock files for each store are recommended.
  • Client should provide hourly stock-price updates.
  • Client should send both price and stock information in the same update file and send all changes (including stock out) as Fashion Connector Importer does not keep track on orders and relies on partner provided stock information as only truth.
  • Fashion Connector Importer does not automatically create articles to Partner Provider - stock and price updates for them will be ignored.
  • Fashion Connector Importer will always use the latest update file provided, so in case of system failures a new file will reset stocks and prices to Partner Provider.
  • Fashion Connector Importer removes automatically stock which has not been received since more than 24 hours
