Set a realistic reply commitment, give each inquiry an owner, and record the first helpful response. An automated acknowledgment does not complete the conversation.

Illustrative sensitivity model, not observed results or a validated response-time benchmark. The exponential curve and 12% floor are assumptions. A five-minute comparison uses exactly 5/60 of an hour. An automated acknowledgment is not a completed helpful human response.

What this assumed

  • The exponential curve is an arbitrary sensitivity model, not a validated benchmark or causal evidence.
  • The 12% floor is an unvalidated assumption, not a measured conversion rate.
  • Your entered base close rate is multiplied by the hypothetical time factor; an automated acknowledgment is not a helpful completed response.

This is an estimate

This tool returns an estimate based on the numbers you entered. Your real result depends on your own costs, rates and conditions. Check it against your own records before you make a decision with it.

What this tool actually does for you

Who it is for

Anyone getting leads from a website form, Facebook, Google or a referral.

The problem it points at

You get the email at 9am, see it at 4pm, call at 5:30. By then they already booked somebody who called back in ten minutes.

What you walk away with

A visible comparison of assumptions and a reason to track your own response times.

How to use it

Takes about two minutes. Be honest with the numbers, the tool is not going to tell anybody.

  1. Enter how many leads you get and how long you actually take to reply.
  2. Compare it against a five-minute reply.
  3. Assign a person and an achievable next step to each inquiry.

Put this tool on your own website

Free forever. I host it. You keep it.

  2. Copy the one line you get.
  3. In your website editor, add an Embed, HTML or Custom Code block on whatever page you want it on.
  4. Paste it in, save, publish.
  5. Check it on your phone, then send people to that page.

Works on

WordPress, Wix, Squarespace, Shopify, GoDaddy, Webflow, Duda, HubSpot, ClickFunnels, or plain HTML. Anywhere that takes an embed code.

What it costs you

Nothing. No monthly fee, no expiring trial, no watermark you have to pay to remove. If you get stuck putting it in, text me at (903) 500-8898 and I will help you place it.

One useful tool is the proof

Now imagine the whole website doing real work.

A five-page site built to capture leads and follow up, in accounts you own. The result is a working site, not a promise of leads.
