Ask HN: Make sense for me to upload data for companies or should company?

I'm providing a service for companies to access my website and upload their website data. Its not a lot of info, and the data doesn't change once its been finalized.

I asked a friend what he thinks about me offering the companies 'parent-child access' so they can distribute the 'permissions' among themselves in the same company. For example, with 'parent-child access', then the graphics guy can upload the images, the secretary can upload the data and the boss can be in control of ALL the data. He said I should do all the work!

Does it make sense for them to upload the data? Is it putting me in a bad position?

If I need them to join my website (maybe or maybe not more than they need me) should I be offering to upload this data for them? There will be some data that I will not have access to until some uploads it.

How do you look at a company that asks you to do all the work? Is it wrong? How far do companies have to go for their clients even if they both need each other?
