MIT and Harvard-backed research shows inbound lead qualification rates collapse exponentially as response time increases. Qbox keeps you in the first-response window, automatically.
Inbound lead qualification rate by response time*
% of web-generated inbound leads successfully qualified by a sales rep
Qbox allows you to reply under 5 minutes, every time. Just like you.
78% of sales go to the first company to respond. Firms responding within 1 hour are 7× more likely to qualify a lead — and at 24+ hours, that drops to 60× less likely. — Oldroyd et al., HBR (2011) & MIT/InsideSales (2007)
* Illustrative estimates based on inbound qualification data from Oldroyd, McElheran & Elkington — Harvard Business Review (2011) and the Lead Response Management Study — MIT & InsideSales.com (2007). Actual rates vary by industry, lead source, and sales process. These figures represent the proportion of web-generated inbound leads that are successfully qualified — not closed deals.
