Referrals convert better and cost less. Paid supply scales on demand. They solve different problems, and the useful question is how to balance them.
The comparison is usually framed as a choice. It is better understood as two instruments with different response times, because the reason to run both is that neither does the other's job.
| Referrals | Paid enquiries | |
|---|---|---|
| Conversion | Highest available | Materially lower |
| Cost per client | Lowest | Higher, and knowable in advance |
| Can you set the weekly volume? | No | Yes, immediately |
| Response time to effort | Months | Days |
| What it depends on | Past client experience and relationships | Money and calling capacity |
| What it tells you when it dries up | Something happened months ago | You changed the order |
The last row is the one worth sitting with. A referral drought is information about the past, and by the time you notice it the cause is out of reach.
Because most of the trust-building has already happened. A referred client arrives having been told by someone they trust that you are worth talking to, which removes the entire first stage of a purchased-enquiry conversation.
It also removes the response-time race. A referred client expects your call and will wait for it. A purchased enquiry is subject to the decay the MIT Sloan research measured, where contact odds fall by a factor of 100 between a five minute and a thirty minute response.
What that difference does not mean: It does not mean paid supply is a poor channel. It means the two have different jobs. Comparing them on conversion alone is comparing a channel you can control against one you cannot.
Treat referrals as the floor and paid supply as the fill. Work out how much capacity your referral and repeat flow typically consumes, then buy to the gap between that and your total calling capacity.
Substitution. A broker who starts buying enquiries and quietly stops asking for referrals has replaced a cheap channel with an expensive one, and the effect is invisible for a quarter because the referral flow already in the system keeps arriving.
By the time it shows up, the acquisition cost has moved permanently and the work needed to restore referral flow takes months to pay back.
The check that catches it: Track referral share of new clients quarterly. If it is falling while total volume holds, you have substituted rather than added, and the cost per client is drifting upward under a stable-looking revenue line.
Not in itself. What harms it is the capacity crowding that follows: an adviser working more enquiries has less time for the client care and follow-up that produces referrals. That is a capacity decision rather than a channel one, and it is avoidable by sizing supply to the hours you actually have.
They convert better and cost less, and they cannot be turned up when you need them because referral flow is a consequence of work done months earlier. Paid supply converts worse and can be set weekly. The two solve different problems, which is why most established brokers run both rather than choosing.
Measure your referral and repeat flow over several months, calculate your total calling capacity from hours at roughly 35 minutes per lead across six attempts, and buy the difference. Hold that weekly volume constant rather than topping up when the diary looks empty, which is what recreates a feast and famine cycle.
Not directly. The risk is capacity crowding: an adviser working more enquiries has less time for the client care and follow-up that generates referrals. Sizing supply to the hours you actually have, rather than to a revenue target, avoids it.
Track referral share of new clients quarterly rather than monthly. If that share is falling while total volume holds steady, you have replaced a cheap channel with an expensive one. Revenue can look stable for a quarter while cost per client drifts upward underneath it.
