From knowledge base
First sale within 7 days: sellers who achieve this retain at 80% at 90 days. Sellers who don't sell in 30 days churn at 60% by day 60. First sale speed is the single most important activation metric.
Italian seller pain points: (1) VAT/tax complexity for P.IVA threshold (€5K/year), (2) shipping cost visibility — sellers don't know what to charge, (3) English-only documentation creates friction. Fixing these three removes 60% of onboarding complaints.
WhatsApp outperforms email 3x for Italian seller engagement. Response rate to WhatsApp: 67% within 4 hours. Response rate to email: 23% within 48 hours. All high-touch seller success work should be WhatsApp-first.
