Addon to Multi-Vendor, Multi-Vendor PLUS, Multi-Vendor Ultimate allows to add "file" fields to vendor application form, to attach additional files to application. New vendor can send his logo, signed agreement or other documents inside the form.
We start from installing an extension:

When adding new vendor profile field, a new type of field "Add file" has appeared:

File field is displayed as "Upload file" link. Clicking it lets vendor load any file and send it with other fields data:

File can be downloaded by main administrator in administration panel, on vendor card. File can be also modified or deleted.

With this add-on, vendors can attach to application their logo, or signed cooperation agreement.
We invite you to shopping!
