DEALERSHIP REALITY CHECK
Slow Lead Response Could Be Costing Your Dealership Thousands
A lead that waits too long is not just a missed call. It is lost opportunity, wasted marketing spend and potential gross profit leakage.
Speak to TatnallHow This Calculator Works
The calculator uses a simple opportunity-cost model. Leads responded to after 60 minutes are treated as heavily reduced in value. The model applies an 85.7% lost-value factor, based on the principle that delayed response makes a dealer significantly less likely to create a meaningful conversation.
Formula:
Delayed Leads × 85.7% × Conversion Rate × Average Profit Per Sale = Estimated Cost of Inaction
Figures are illustrative and should be adapted to each dealership’s own CRM data, lead source performance, cost per lead, conversion rate and retained profit per sale.
GETTING TO THE ROOT CAUSE
Tatnall Helps Fix More Than the Symptom
Slow lead response is rarely just a “sales executive issue”. It is usually a deeper operational problem linked to ownership, process, accountability, CRM usage, management rhythm, out-of-hours handling or team behaviour.
That is why the Tatnall logo carries roots beneath the T. The aim is not to apply a surface-level fix. It is to get underneath the problem, identify the real cause and help the dealership build a process that actually holds.
Process Diagnosis
Review how enquiries arrive, who owns them, how quickly they are handled and where the process breaks.
CRM & Accountability
Identify whether the issue sits in CRM discipline, follow-up quality, reporting, management control or ownership.
Practical Retail Fixes
Build simple, usable actions that work in a real dealership environment, not just on a process document.
