Forced to upgrade with 0 mb used, and not even my own content

[Fingerprn]

My client gave me access to their Dropbox files through my account. Other than my client's files, I don't even use my account. The problem is that my client's employees keep adding files to their account. They're over 9 GB now, so Dropbox is forcing me to upgrade to a Plus account.

It doesn't make sense that I have to pay for their storage. At this point, I discourage my other clients from using Dropbox for this reason. If everyone used Dropbox, I'd be paying for a Professional account that contains none of my files.

Is there another option I'm not familiar with?

Do you need read/write access to the files? If so that is the only way to do it - upgrade the account. Ultimately if they are your client then you are probably going to charge them for the access anyway, or, have the resources to access what the client wants.

If you need to do just read write then use www.dropbox.com/links. 

If you just need to send them things use Requests: www.dropbox.com/requests.
