Rough estimate. How much conversion drops when you answer late varies a lot by industry: if you don't know it, start with a cautious value and check it against your own data.

How it's calculated

  1. Leads answered late per year = leads per month × 12 × share answered late.
  2. Sales lost per year = leads answered late × close rate when answered on time × drop in conversion from answering late.
  3. Margin lost per year = sales lost × average margin per sale.

We use margin rather than sale price because that's what you actually stop earning. At a car dealer, for example, a deal's margin includes that of the vehicle, the financing and the associated services.

A worked example

A dealer receives 150 leads a month. 40% are answered late, outside opening hours or at the busiest times. When it answers on time it closes 8% of leads, and it estimates that answering late cuts that conversion by half (50%). Its average margin per deal is €900.

  • Leads answered late per year: 150 × 12 × 40% = 720.
  • Sales lost per year: 720 × 8% × 50% = 28.8.
  • Margin lost per year: 28.8 × €900 = €25,920.

Why speed matters so much

A study published in Harvard Business Review in 2011, based on more than 2,000 US companies, found that those that tried to contact a lead within the first hour were nearly seven times as likely to qualify it as those that waited an hour longer, and far more likely than those that took a day. The data comes from another country and another time, but the logic still holds, all the more with WhatsApp: prospects write to several listings at once and go with whoever answers first.

How to cut response time

The most reliable way is for the first reply not to depend on someone being free. A digital employee answers within minutes, at any time, with real product information, qualifies the prospect and hands them to sales when they're ready. We cover it in detail in how to automate lead handling on WhatsApp and email and, for the automotive case, in automation for car dealers and leasing.

Frequently asked questions

What counts as answering late?

It depends on the industry and the channel, but as a practical reference: on WhatsApp or chat, more than a few minutes; by email or form, more than an hour. What matters is comparing your real response time with your competitors', who are one click away.

How do I know how many leads I answer late?

Your CRM usually records when the lead came in and when it was first contacted; WhatsApp Business and listing portals also show response times. If you don't have the figure, check a sample of your last 50 leads by hand.

What value should I use for the drop in conversion?

Without your own data, start with a cautious value between 20% and 50% and compare it later with what you see when response times improve. Published studies point to much larger drops when the wait is measured in hours.
