Most agency owners know that a missed enquiry is bad. Fewer have put a number on it. When you do, the number is usually bigger than expected, because the cost of a missed property lead does not stop at one sale. Buyers turn into sellers, sellers recommend friends, and valuations lead to instructions.
This post walks through a worked example so you can do the same arithmetic with your own figures. Everything here is hypothetical and clearly labelled. Swap in your own numbers as you go.
What "missed" really means
A missed enquiry is not only one that nobody answered. It includes the enquiry that got a reply two days later, after the buyer had already viewed with another agent. It includes the Sunday night enquiry that sat in the inbox until Monday. We covered that pattern in buyer enquiries that arrive on Sunday night.
So when you count missed enquiries, count the slow ones too. For most agencies, slow replies cost far more than ignored ones, because ignored enquiries are rare and slow ones are routine.
The worked example: one small agency
Here is a hypothetical sales agency. The numbers are chosen to be easy to follow, not to represent any particular market.
| Step | Assumption | Result |
|---|---|---|
| Website enquiries per month | 120 | 120 |
| Share that are serious buyers | 50% | 60 |
| Share lost to slow replies | 20% | 12 buyers |
| Share of those who would have viewed | 60% | about 7 viewings |
| Share of viewings leading to a purchase through you | 10% | about 0.7 sales |
| Average fee per sale | $5,000 | about $3,500 a month |
So in this example, slow replies cost roughly $3,500 a month in buyer-side sales, or about $42,000 a year. That alone is a meaningful number for a small agency.
The part most agencies leave out
The table above only counts the buyer's purchase. It leaves out what often matters more: many buyers have a property to sell.
Suppose a third of those lost buyers also needed to sell. Each one you never spoke to is a valuation you never did and an instruction you never won. If even one lost buyer a month would have instructed you to sell, add another $5,000 a month in this example.
That changes the picture. The missed enquiry was not worth one possible sale. It was worth a possible sale plus a possible instruction, and sometimes a referral after that. Our guide on what missed enquiries actually cost your business explains how to count these knock-on effects in any industry.

Where the losses actually happen
When agencies look at their enquiry timestamps, the gaps usually fall in three places.
Evenings and weekends are the obvious one, when buyers browse and offices are closed. Busy mornings are the second, when negotiators are out on viewings and the office is short-staffed. The third is the backlog after a holiday or a sick day, when enquiries pile up faster than anyone can clear them.
Each gap has the same effect. The buyer waits, and while they wait, another agent replies.
What it costs to fix
Once you have your own figure for lost revenue, compare it with what it costs to reply faster. The options usually look like this:
- A negotiator on an evening rota. Effective, but it costs goodwill and tends to fade over time.
- An additional hire. Worth it at high volume, expensive for a small office.
- A phone answering service. Covers calls, but does nothing for website enquiries.
- A website assistant. Answers on your site at any hour and captures details for your team.
SpideyChat for real estate is the last option. It answers buyer questions from your listings and property pages, asks your qualifying questions and captures viewing requests, so your team starts each morning with qualified leads. You can see the plans and prices and compare them with your own lost-revenue figure.
The comparison with a hire is worth making explicit. In the example above, the agency loses around $40,000 to $100,000 a year to slow replies. A website assistant costs a small fraction of that. It does not replace negotiators, who still do the viewings, valuations and negotiation. It covers the first reply, which is exactly the part that tends to go wrong.
Lettings enquiries follow the same maths
If your agency also handles lettings, run the numbers again for that side. The figures per enquiry are smaller, but the volume is usually higher and the timing is harsher. Rental enquiries often arrive in bursts within hours of a listing going live, and good tenants tend to take the first suitable place that answers them.
There is a landlord angle too. A tenant who has a good experience with your agency is a likely buyer in a few years, and landlords judge agencies partly on how quickly their properties are let. A slow reply to a tenant enquiry costs a let today and some goodwill with the landlord who is watching.
Running your own numbers
To work out your figure, you need five numbers:
- Website enquiries per month.
- The share you estimate are lost to slow or missing replies.
- Your enquiry to viewing rate.
- Your viewing to sale rate.
- Your average fee.
Multiply them through, then add an allowance for sellers among the lost buyers. If you prefer not to build a spreadsheet, the free chatbot ROI calculator does the arithmetic for you.
For a wider view on this kind of modelling, modelling the cost of slow replies with your own numbers walks through the method for any business.
What to do with the number
If your figure is small, you may be fine as you are. Some agencies with a low volume of enquiries and a strong evening routine already reply quickly.
If the figure is large, the fix is usually not more effort from the same people. It is covering the gaps where nobody is available. Start with the biggest one, which for most agencies is evenings and weekends, and measure the difference over a couple of months.
