Pricing: What You Actually Pay

The sticker price tells half the story. The real cost includes the tools each platform replaces (or requires you to keep).

Warmly — Total Cost

Platform: ~$700-$1,500/mo (based on traffic volume)

Replaces: Standalone chat tool (~$200/mo), intent data provider (~$300/mo), routing middleware (~$100/mo)

Net cost after tool consolidation: ~$100-$900/mo

RB2B — Total Cost

Platform: $0-$200/mo

Still need: Outreach tool (~$100-$300/mo), CRM routing (~$100/mo), chat tool (~$200/mo), Zapier (~$50/mo)

True total stack cost: $450-$850/mo

When you factor in the tools RB2B doesn't replace, the actual cost gap between the two approaches narrows significantly. Warmly's higher sticker price buys consolidation.
