The verdict in three sentences
Agencies and referral partners who win in B2B combine targeted outbound and referrals, not passive waiting. A warm referral closes at around 30 % versus 3 to 5 % for a cold contact — that is lever number one. With a disciplined pipeline, 100 qualified leads produce 5 to 10 signatures, a predictable ratio luck never matches.
Channels and their real rates
Not all channels are equal. Here are 2026 orders of magnitude observed on the West African market.
| Channel | Reply rate | Close rate | Acquisition cost (CAC) |
|---|---|---|---|
| Cold email | 2 – 5 % | 3 – 5 % | 40,000 – 100,000 FCFA |
| LinkedIn outbound | 5 – 10 % | 5 – 8 % | 30,000 – 70,000 FCFA |
| Targeted WhatsApp Business | 8 – 12 % | 6 – 10 % | 20,000 – 50,000 FCFA |
| Warm referral | 40 – 60 % | ~30 % | < 15,000 FCFA |
| Field (markets, associations) | 15 – 25 % | 10 – 15 % | 25,000 – 60,000 FCFA |
The CAC for an SME web deal runs 30,000 to 100,000 FCFA. Referrals stay unbeatable: low volume but a massive close rate.
The pipeline in numbers
An acquisition engine is run like a funnel. Here is a realistic projection over one month of serious work.
| Stage | Volume | Pass-through |
|---|---|---|
| Outbound contacts | 100 | — |
| Replies | 8 – 12 | 8 – 12 % |
| Meetings / demos | 5 – 8 | ~60 % of replies |
| Proposals sent | 4 – 6 | ~75 % of demos |
| Signatures | 5 – 10 | depends on mix |
The vitrine cycle lasts 1 to 3 weeks; institutional 2 to 6 months. A follow-up sequence of 5 to 7 touches and a callback within 24 h double conversion. Proof from a local case study clearly lifts the close rate.

Mini case study
Fatou, a referral partner in Lagos, contacts 80 shopkeepers via WhatsApp Business in a month. She gets 9 replies (11 %), runs 6 demos and closes 3 vitrines at 400,000 FCFA each. At 15 % commission, that is 180,000 FCFA. In parallel, one referral from a happy client brings her a 4th signature with almost no effort. Her average CAC: about 35,000 FCFA per deal, for an average commission of 60,000 FCFA.
FAQ
Is inbound alone enough to live off referrals? Rarely at the start. Inbound takes months to produce; an outbound + referral engine generates signatures in the first week with a CAC of 30,000 to 100,000 FCFA.
Why do referrals close so well? Trust is already transferred. A warm referral closes at around 30 % versus 3 to 5 % cold — six to ten times better at near-zero cost.
How many follow-ups are needed? A sequence of 5 to 7 touches is standard. Most replies land after the 3rd message, and a callback within 24 h after a demo doubles conversion.
Which channel to prioritize in 2026? WhatsApp Business shows the best reply rates (8 to 12 %) and the lowest CAC. LinkedIn stays key for institutional deals and decision-makers.
How do I know my pipeline works? Track the final ratio: 100 qualified leads should produce 5 to 10 signatures. Below that, rework the targeting or the opening hook.
