Hello,
And thank you for participating in your community.
Both actions you are looking for are available at the account admin level. So to be able to bulk import members or to add companies, you will need to be an account admin, as explained in the articles you mentioned.
To bulk import Members.
You can bulk-import multiple members to an account by using a spreadsheet.
1. In account administration, click Members.
2. Click Add > Import Members By Spreadsheet.
3. Do one of the following:
4. For a first-time import, click Download A Member List Template and open it with Excel. In the template, replace the example entries with your actual member details, one member per row, and save the file. Then click Choose File to select the spreadsheet.
5. If you have a properly formatted member list spreadsheet, click Choose File and select the spreadsheet.
6. Click Start Import.
To add companies.
You can add companies to the company directory or import companies from a Microsoft Excel file. When you add companies to the directory, any project administrator can use the search feature to invite them to their project without creating duplicate entries.
1. In account administration, click Companies.
2. Click Add.
3. In the Create Company dialog, specify the company name.
4. Enter or select a trade from the list.
5. For Company Logo, click Browse to upload an image.
6. Click Save to add the company to the directory.
I hope this was helpful.
