Based on Vendr's pricing intelligence, Splunk On-Call shows significant volume discount opportunities as you scale. For 50 users, you're looking at a list price of $14,100 annually, but our data shows companies typically achieve 10-13% discounts at this tier, bringing costs down to $12,300-$12,700. However, when scaling to 100 users ($28,200 list), the discount potential increases dramatically to 16-23%, resulting in $21,700-$23,700 in actual spend. The key negotiation strategy here is to commit to your growth trajectory upfront. Instead of purchasing 50 seats now and expanding later, negotiate a 200-user deal ($56,400 list) where Vendr data shows 22-35% discounts are achievable, bringing your total to $36,600-$44,100. This approach saves you approximately $8,000-$12,000 annually compared to incremental purchases. Additionally, request a true-up mechanism that allows you to add users quarterly without penalty, and negotiate unused seat rollover credits to maximize your investment efficiency.
