Hi there, @user19107 
If you’re managing your clients’ widgets yourself, one subscription should be enough.
The subscription plan you choose will depend on how many widgets you need. For example, if you need one Social Feed widget for each of your clients, the Social Feed Pro Plan would be the best option for you [1]:
With the Social Feed Pro plan, you can create up to 9 Social Feed widgets. It also gives you a total of 50,000 views per month across all your widgets (not 50,000 views per widget). For more information on how our view system works, feel free to check out this article 
If you’re planning to stick around for the long term, we recommend choosing an annual plan, as it’s 17% cheaper than the monthly plans. Plus, if you choose an annual plan, the 50% Black Friday discount will be applied automatically at checkout!
To sum it up, the Social Feed Pro annual plan is likely your best option right now. However, if you need more widgets or views in the future, you can easily upgrade to a higher plan.
By the way, if you upgrade your plan during our Black Friday Sale, you have a great chance to win 1 FREE YEAR by participating in our Giveaway - BF 2024 Giveaway: Win 1 YEAR of Free Usage (10 Winners) + guaranteed month!

1 widget can be installed to the unlimited number of websites. However, if a client wants to show different social feeds on different website, he’ll need several widgets. Thus, if the total number of widgets for all customers exceeds 9, you’ll need a higher plan ↩︎
