Vendr's pricing intelligence reveals that Sendoso's tier pricing isn't as straightforward as their marketing suggests. Here's the real breakdown based on our data: Starter Plan: Fixed at $5,000 annually (no negotiation flexibility), Essential Plan: $19,947 for 8 users, with 37-51% discount potential, Plus Plan: $37,880 for 15 users, with 40-57% discount potential, Pro Plan: $50,956 for 10 users, with 41-61% discount potential. The per-user cost actually decreases as you move up tiers when factoring in negotiated rates.
