Speed to contact: the money you lose between the form and the first call

What it costs to be slow calling a lead, what a first-contact SLA is, and how to keep track of the missed calls coming in from your ads.

A lead that arrives on a Friday at 17:30 and gets its first call on Monday at 11:00 has waited 65 hours. In that time they have filled in three more forms, spoken to two competitors, and stopped remembering why your company interested them.

The ad worked. The landing page worked. The form worked. The money was lost afterwards, in a gap that almost no company measures: the time between the form and the first call.

Where the gap is

Campaigns are optimised up to the form. The CRM starts at the first call. In between there is a space that belongs neither to marketing nor to sales, which is precisely why nobody watches it.

Specific things happen in that space:

  • The lead lands in an inbox and waits for someone to open it.
  • It gets assigned to a salesperson who is out on a visit.
  • Someone calls once, nobody answers, and it is left for “later”.
  • It arrives out of hours and there is nobody there.
  • Someone calls the number in the ad, nobody picks up, and there is no record that they called.

Each of those has a cost. What was paid for the click, plus what was paid for the form, plus the sale that did not happen.

Why speed matters so much in B2B

In B2B the buyer is supposed to be rational and patient. To compare, evaluate and decide calmly. In practice, someone filling in a form has a problem right now. They have decided to spend fifteen minutes looking for solutions and have contacted several suppliers. The first one to respond with substance sets the terms of the conversation. Everyone else has to compete against that benchmark.

This is not about being pushy. It is about being available. The lead is paying attention at the moment they submit the form. Every hour that passes, they are paying less.

The first-contact SLA

A first-contact SLA is an internal commitment: every new lead gets a first contact attempt within X time. It is defined, it is measured, and it is reviewed.

It is made up of three decisions:

DecisionExampleWhy it matters
Maximum time15 minutes during working hours, first thing the next day outside themWithout a number there is no commitment
What counts as contactA call made (not an automated email)An automated email is not contact
What happens if it is missedAlert to the manager, reassignmentWith no consequence, the SLA is forgotten within two weeks

The specific time depends on the business. What does not depend on the business is that it exists and gets measured.

Measuring it: the stopwatch

To measure an SLA you need to know two moments precisely: when the lead came in, and when the first contact attempt was made. The first comes from the form. The second has to be recorded by the CRM when the salesperson calls.

With those two, every lead has a stopwatch. The dashboard shows how many leads are inside the window, how many are outside it, and how long they have been waiting. Nothing more is needed.

What is needed is for the call to be logged at the time. If the salesperson calls and writes it up at the end of the day, the stopwatch lies. That is why the CRM has to make logging easy: one button, not a ten-field form.

Alerts: who finds out, and when

A stopwatch nobody looks at is useless. The next step is alerts:

  • New unassigned lead: alert to the sales manager.
  • Assigned lead with no contact within the window: alert to the salesperson.
  • Lead at double the allowed time: alert to the manager, with the option to reassign.

Alerts go through whichever channel the team already uses. Email, message, CRM notification. What matters is that they reach a person with a name, not a distribution list.

The calls nobody sees

There is a part of the problem the form does not cover. Many ads, especially on mobile, include a phone number. The user calls directly. If nobody answers, there is no form, no lead in the CRM, no record. As far as the company is concerned, that call never happened. As far as Google is concerned, the click was paid for all the same.

Call tracking from ads solves this. A tracking number in the ads lets you know which calls came from which campaign, which were answered, and which were missed. A missed call from an ad becomes a lead in the CRM with the status “unanswered” and its own stopwatch. Nexus includes this tracking and joins it to the rest of the measurement, so a call counts the same as a form when working out cost per qualified lead.

What you see once you start measuring

When a company switches the stopwatch on for the first time, it usually discovers three things:

  1. Average time to first contact is far higher than anyone believed. Salespeople remember the leads they called quickly, not the ones that sat in the inbox.
  2. There are leads that never received a call at all. They were assigned, forgotten, and went stale.
  3. Leads that arrive outside working hours have a much lower contact rate. Not because they are worse, but because they go cold.

None of the three is fixed by spending more on ads.

What changes when it is fixed

Cutting time to first contact raises the contact rate, and the contact rate raises the qualification rate. Same leads, more conversations. Same conversations, more sales.

And it has an effect on measurement. A lead that was never contacted gets logged as “not qualified” or left with no status at all. If that signal goes back to Google or Meta, the platform learns that the lead was bad. It was not. It was a lead nobody called. An SLA that is actually met cleans up the signal the campaign receives.

Where to start

Before buying tools or changing processes, it is worth measuring for a week. Pull the leads from the last thirty days, with the date they came in and the date of the first call logged in the CRM. Work out the difference. The result tells you how big the gap is.

If the CRM does not hold that date, the first job is to make it hold it. If it does and the gap is large, the job is the SLA, the stopwatch and the alerts. The diagnostic reviews the flow from the ad to the first call and identifies where the lead is lost in your company.
