Free calculator for trades and service businesses
What are missed enquiries really costing your business?
Estimate the revenue and gross profit lost through unanswered calls, slow replies and enquiries that never receive proper follow-up.
Calculate the hidden costYour enquiry leakage
Turn missed calls and slow replies into commercial numbers.
Use a representative month and include phone calls, website forms, WhatsApp messages and social enquiries. Count an enquiry as missed when nobody replies promptly enough to give the business a fair chance of winning it.
Your estimated monthly leakage
At the figures entered, reducing missed enquiries from 20% to 5% could recover about 4.1 initial jobs a month.
Annualised initial revenue at different missed rates
This is an estimate, not a financial forecast. It assumes missed enquiries have broadly similar qualification and conversion potential to answered enquiries. It excludes VAT, tax, refunds, bad debt, capacity constraints and changes in lead quality.
The hidden leak
Businesses often pay for enquiries they never properly handle.
A roofer can invest in SEO, a cleaner can pay for Google Ads and a service company can work hard for referrals, yet part of that demand disappears when calls ring out, messages sit unanswered or quotes receive no follow-up.
The marketing report may still look healthy because the call or form submission was recorded as a conversion. Commercially, however, an enquiry has value only when it reaches a real person, receives a useful response and is managed through to a decision.
This calculator connects response failure to the business numbers that matter: qualified opportunities, expected jobs, revenue and gross profit.
Where enquiries disappear
Missed does not only mean an unanswered phone call.
No answer
The phone rings while the owner is driving, working at height, with a customer or operating machinery.
Slow response
A form, email or WhatsApp message receives a reply after the customer has already booked another company.
Weak handover
Details are incomplete, nobody owns the next step or the enquiry is lost between the office and the person quoting.
No follow-up
A quote is sent once and silently abandoned, despite the customer still considering the work.
The calculation
How the missed enquiry calculator works
The tool applies your own qualification and conversion rates. It deliberately avoids the inflated assumption that every missed contact would have become a customer.
1. Missed opportunities
Total incoming enquiries are multiplied by the percentage currently missed or poorly handled.
monthly enquiries x missed rate2. Expected jobs lost
Missed contacts are discounted by both the qualification rate and the normal conversion rate.
missed enquiries x qualified rate x conversion rate3. Commercial value
Expected jobs are multiplied by initial job value, repeat value and gross margin where relevant.
expected jobs x customer value x gross marginWorked example
An 80-enquiry service business missing one in five
The default example shows how a fairly ordinary response problem can become a meaningful commercial leak.
- Incoming enquiries80 per month
- Missed or poorly handled20%
- Qualified enquiries75%
- Conversion rate45%
- Initial job value£500
- Additional 12-month value£150
Sixteen monthly enquiries are missed. If 75% would have been qualified and 45% of those would normally convert, their expected value is 5.4 jobs.
At £500 per initial job, that is £2,700 in expected monthly revenue. Including £150 of evidenced additional 12-month customer value, the missed cohort represents £3,510 in revenue and approximately £1,931 in gross profit.
Reducing the miss rate from 20% to 5% would not recover everything. At the same qualification and conversion rates, it could recover about 4.1 initial jobs and £2,633 of 12-month customer value per month.
Use honest inputs
A useful estimate depends on measured behaviour.
Define a missed enquiry consistently
Agree what counts: unanswered calls without a timely callback, forms not answered within the expected window, social messages overlooked or quotes never followed up. Consistency matters more than pretending every business needs the same response time.
Separate genuine enquiries from noise
Wrong numbers, suppliers, recruitment calls, spam and jobs outside your service area should not inflate the total. The qualification input then accounts for genuine prospects who are still unsuitable.
Use answered-enquiry conversion
Measure the proportion of qualified enquiries that become paying jobs when handled normally. If you combine qualified and unsuitable contacts, the conversion rate will understate the value of a genuine opportunity.
Be conservative with repeat value
Include additional customer value only when records show that repeat work, servicing or follow-on jobs actually occur. Enter zero if the service is normally a one-off purchase.
What to fix first
Match the response system to the reason enquiries are being lost.
| Problem | What to measure | Practical response |
|---|---|---|
| Calls missed during jobs | Calls by hour, callback time and whether the caller answers the callback | Use call routing, a named office responder, a carefully briefed answering service or an immediate text acknowledgement. |
| Forms and messages answered late | Time from submission to first useful human response | Centralise notifications, set ownership and use an acknowledgement that gives a realistic response window. |
| Poor-quality enquiries | Qualification rate by channel, service and location | Improve page targeting, service-area clarity, offer wording and campaign exclusions before buying more traffic. |
| Quotes go quiet | Quote-to-job conversion and follow-up attempts | Create a simple follow-up sequence and record the real reason work is won or lost. |
| Fast response but weak conversion | Conversion by staff member, lead source and job type | Review qualification, trust, pricing, explanation of value and the quoting experience. |
Before buying more leads
Recovering existing demand may be the highest-return marketing move.
Generating a new enquiry usually has a visible cost. Recovering one that the business has already paid for may require a clearer process, faster ownership and better tracking rather than additional advertising.
That does not mean every business needs a call centre or instant replies at all hours. The right system should reflect lead value, enquiry volume, customer expectations and the reality of delivering the work.
Do not automate the customer out of the experience.
Automated acknowledgements and CRM reminders can stop enquiries disappearing, but they should support a useful human response. A fast generic message is not the same as properly handling the enquiry.
Frequently asked questions
Missed call and enquiry questions
What counts as a missed enquiry?
A missed enquiry is a genuine contact attempt that does not receive a sufficiently timely and useful response for the business to have a fair chance of winning the work. This can include unanswered calls, overlooked forms, delayed messages, failed handovers and quotes that should have been followed up.
Does every missed call mean a lost customer?
No. Some callers are unsuitable, some contact several businesses and some would not have bought even after a good response. The calculator therefore applies both a qualification rate and a conversion rate instead of valuing every missed contact as a completed job.
How do I measure my missed-enquiry rate?
Record genuine enquiries across phone, forms, email, WhatsApp and social channels. Mark those that were not answered or progressed within your defined service standard, divide that number by total genuine enquiries and multiply by 100.
How quickly should a trade business respond to an enquiry?
There is no single responsible promise for every trade. Urgent repairs, planned projects and specialist services have different customer expectations. Measure your own conversion by response time, then set a standard the business can actually maintain.
Should repeat customer value be included?
Include it only when you have evidence that newly acquired customers commonly buy again within the period. Use an average across all new customers rather than only those who return. Enter zero for primarily one-off services or when reliable data is unavailable.
Can an answering service solve the problem?
It can help when unanswered calls are the main leak, but only if the service understands what information to collect, what the business offers and how the handover works. Answering a call without progressing it merely moves the bottleneck.
Is slow follow-up a marketing problem or an operational problem?
It is both. Marketing creates demand, while operations determine whether that demand becomes revenue. Measuring only traffic, calls or forms can make a campaign appear successful even when the commercial process is leaking opportunities.
Use the full picture
Fix the leak, then decide whether you need more demand.
If the potential recovery is material, investigate response speed, enquiry ownership, qualification, quoting and follow-up before increasing marketing spend. If leakage is already low and capacity exists, stronger visibility may genuinely be the next constraint.
Local Edge Digital helps owner-led trade and service businesses connect marketing with the commercial reality behind it: pricing, margins, conversion, capacity and customer handling.
