One way to make it easier is to use a social media management tool, such as Sprout Social.  Sprout Social can help your organization manage all your social media accounts from Twitter to LinkedIn.

Use Sprout’s social inbox to manage all your social media accounts from one dashboard.

With Sprout you can create a publishing calendar. If your social media campaigns are run by different teams, you can have the teams collaborate via the platform, but you also have the ability to grant permission based access.

Sprout lets you create campaigns, edit photos, track tags and respond to messages you’ve received on your social media accounts.

It also has a variety of analytical reports that gives you insight into the effectiveness of  your campaigns.

Buffer can be used on desktop or on mobile devices. And, you can have multiple people creating the content, you can limit the permission of various users. Buffer also includes analytics so you can see how your posts are performing.

Sprout Social offers several tiers of pricing. You can inquire about special discounts for nonprofit organizations. The standard plan is $99/per month per user. This includes up to 5 social media accounts.
