High Deal-Risk · Constraint Mismatch

Estimated Floor (5 Seats · Enterprise / Custom)Custom Quote (Custom / enterprise pricing)Vendor does not publish a self-serve USD floor on its pricing page; requires sales qualification.Sales-gated pricing vs. $800/mo cap (High quote risk)

Opaque Enterprise Quoting vs. SMB/Mid-Market Budget: Diffly does not disclose a public self-serve floor (Custom / enterprise pricing). Buyers with a $800/mo cap face high sales-qualification friction.
Sales-Gated Contract Terms: Commercial pricing is available on request through tailored enterprise sales quotes based on organizational scale and seats. Contracts typically accommodate closed-opportunity intake volume, CRM integration boundaries, and dedicated workspace provisioning.
Primary Operational Bottleneck: Buyer Response Attrition: External response conversion hinges entirely on external buyer willingness to engage automated interview prompts, resulting in thin sample sizes for low-velocity commercial pipelines.

Walk-Away Rule: Walk away if you require transparent self-serve monthly billing or your budget ceiling is under $1,000/mo (Diffly requires sales-gated custom quoting).

Negotiation Lever: Demand a 30- to 60-day paid pilot opt-out clause in the Diffly order form before signing a 12-month enterprise commitment.
