Data format and requirements for the inventory import

The inventory import upload supports CSV or TXT file formats. The easiest way to get a CSV file in the correct format is to export your existing inventory. You can then apply necessary changes to the file using Excel or any other spreadsheet tool, and upload the updated CSV using the inventory import back to Rentle.

Your inventory's CSV file must comply with a few important formatting rules so it can be used for the import CSV file:

  • The first row of the exported CSV is a header row that helps Twice identify the columns. Do not modify this row.
  • The seconds row is a localization row, and contains the headers you will see in your uploaded Twice Inventory. Here you find the headers of some predefined inventory columns that cannot be changed without loosing the file's functionality. Additionally to the predefined headers you can add and edit in this row your own specifications.
  • The first column is called "id" and includes the internal ID of an article. Do not modify this column to ensure the file's functionality. When adding a new article, the respective cell in this column should be left blank. All other columns can be added in a free order.
  • When saving your CSV file, please ensure to use the semicolon character ";" as a delimiter

Supported columns for the inventory import CSV file

An example of an inventory import file of a Tools & DYI rental business might look like this:

    Import example

    For the following example shows how a Tools & DYI rental business might upload their inventory at once to Rentle.

    The store wants to add:

    • 3 new Power drills which they want to rent out
    • 50 new hammers of which they want to rent 30 and sell the remaining 20
    • 1 new Lawn Mower, which they don't want to be available for bookings immediately
    • The store also wants to start tracking the purchase prices of all their inventory articles and some specifications depending on the article

    Firstly, the store creates a blank Spreadsheet (here in Microsoft Excel)and adds the minimum required predefined column headers per above. Additionally, the columns "make", "color", and "purchase price" are added.

    (This step can be skipped by exporting an existing inventory from Rentle)

    Then the store will add all their articles and their connected data to the respective columns:

    • For the 3 power drills new Article IDs, SKU Codes and SKU names are created. All three drills shall be available immediately - two for rent and one for sales. Additionally, the store captures the make of the drills and their purchases prices
    • The 50 hammers are added as a bulk article row with a new SKU Code and SKU Name. No Article IDs are necessary here. 30 hammers are allocated for rent and the remaining 20 for rent.
    • The lawn mower is added lastly with a new Article ID, SKU Code and SKU name. It is green, marked for rent, but with the status OUT_OF_USE won't be available immediately for rent.

    Now, the file is saved as a CSV file and the file is ready to be uploaded to Rentle! In the Inventory, via Import the above CSV file is chosen to upload. The following import confirmation view shows:

    The import confirmation view will outline, which articles and fields will be updated as well as all the new articles that will be added. Below it will also list all the new specifications and SKUs. This view helps you to confirm that the import is correct. In case some fields are incorrect, it will also show those and guide you to fix them.

    With a click on confirm import the inventory will be updated with the newly added articles:
