B2B Rocket Margin Stack

B2B Rocket's pricing tiers (Starter at $59/mo, Growth at $99/mo) let agencies buy at wholesale and sell at retail. The Margin Stack framework maps which tier to purchase for internal operations versus which tier to resell to clients. For example, an agency buys the Growth plan ($99/mo) to manage 5 client accounts under one unified inbox, then charges each client $500/mo for a managed outreach service. The margin is $401/mo per client, minus mailbox costs. The framework also accounts for add-on seats and mailbox limits: the Growth plan supports 100 mailboxes, so an agency can scale to 20 clients at 5 mailboxes each before needing an upgrade. The key insight is that B2B Rocket's modular pricing allows agencies to stack margins by buying at a lower tier than what they sell, but only if they monitor active contact limits (200,000 on Growth) and export quotas (5,000 email exports per month).
