sharepoint online (Office365) 3rd party consultant access

We have an organization that has a subscription for Office365 that is hiring a 3rd party Sharepoint developer to assist with design, access and various things.
Does anyone know if its possible to grant this 3rd party developer admin access to the online portal? and if so, how is this done?

An Extranet and Intranet Sharepoint site will be developed and for the extranet site, we look to have consultants that are indirectly working for the organization be accessing and contributing to the site. Are licenses required and would each license be tied to that user that is accessing it? or possible to buy a pool of licenses that can be used for anyone to allow for concurrent access?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

There is such a thing as a Developer subscription for O365. This is a separate site from your production data where the developer can develop Apps.

Those Apps will be deployed to your working O365 subscription via the App Store. A such the developer will never require access to your live O365 site (and indeed your data!).

Thanks for the response.
Looks like the only option provided by MS support was to set as the global admin. Not particularly ideal but it has worked in the mean time...
