Here's the honest answer: most social media management platforms will bleed you dry as you scale, and agency pricing models are deliberately confusing to make that happen.
The standard model across Hootsuite, Sprout Social, and similar all-in-one suites is per-user licensing on a tiered plan, so you pay for a "Pro" or "Business" tier, then pay per additional user you add to your account. What they don't advertise clearly is that each client account you want to connect often counts as a separate user or requires you to move up a pricing tier.
So managing 20 client pages means either 20 separate plan subscriptions (expensive) or one bloated tier (also expensive, plus you're paying for features you don't use).
Some platforms like Hootsuite do offer "client management" add-ons, but these stack on top of your base plan cost. You end up in a spiral where the per-account fees compound as your agency grows, and the pricing page never tells you the real number until you're deep in a demo with sales.
Most platforms use three to four tiered levels, and optional add-ons for additional users or platforms significantly impact total cost. [src-1], TrustRadius
That's software-speak for "we'll nickel-and-dime you as you scale."
Boosterberg is flat $25 per connected social channel per month, one Facebook page or one Instagram page costs $25, whether you're managing it for yourself or a client. 20 client accounts? $500/month. No per-user fees. No "upgrade the whole plan" surprise. Unlimited team members, unlimited campaigns. You know the cost before you sign anything.
If you're evaluating platforms for agency use, pull a real quote based on your actual client count. Don't estimate. That's where most agencies realize their current platform is costing 3–5x what it should. [2]
