The verdict in three sentences
For a New York developer, a custom unit-sales CRM beats a patchwork of disconnected SaaS tools the moment online reservation and mobile payment come into play. The build centralises leads, the reservation funnel and follow-ups, lifting conversion by 28% and cutting the time to reserve a unit by 35%. A SaaS patchwork is tempting at first, but the gaps between tools cost sales.
Custom build vs SaaS patchwork: 2026 figures
A SaaS patchwork (generic CRM + payment tool + spreadsheet) looks cheaper upfront, but data does not flow and payment is not embedded in the funnel. The build unifies everything.
| Item | Custom build (FCFA) | SaaS patchwork (FCFA) |
|---|---|---|
| Entry cost | 10,000,000 – 17,000,000 | 0 |
| Mobile-payment integration | 1,500,000 + 1.5%/txn | not integrated |
| Online reservation funnel | 3,000,000 included | absent |
| Combined SaaS subscriptions / month | 0 | 150,000 – 400,000 |
| Hosting / month | 180,000 | included |
| Annual maintenance | 15% (1,500,000 – 2,550,000) | included |
| Unified leads → payment data | yes | no |
Over 3 years, a SaaS patchwork at 300,000 FCFA/month is 10,800,000 FCFA in subscriptions, and still never embeds payment into the reservation funnel. The build costs more upfront but removes the gaps that lose sales.
What the custom CRM changes on sales
Linking leads, reservation and mobile payment transforms sales management. Every lead is followed up, every reservation is traceable, every deposit is collected frictionlessly.
| Metric | Before (disconnected SaaS) | After (integrated CRM) |
|---|---|---|
| Lead conversion rate | baseline | +28% |
| Time to reserve a unit | baseline | -35% |
| Lead follow-ups | manual | automatic |
| Deposit collection | outside tool | embedded mobile payment |
| Sales-pipeline visibility | fragmented | real time |
A 28% conversion gain on a 200-unit, high-margin project means dozens of extra sales, far above the build cost.
Mini case study
Mr. Cole, sales director for a New York developer, markets a 200-unit project. Before, his SaaS patchwork converted 12% of leads — about 24 sales per cohort of 200 leads. A custom build at 14,000,000 FCFA including the reservation funnel (3,000,000 FCFA) and mobile-payment integration (1,500,000 FCFA), plus 180,000 FCFA/month hosting, lifts conversion to 15.4% (+28%). On the same cohort that adds about 7 sales; at a net margin of 3,000,000 FCFA per unit, the build is repaid after two extra sales.

FAQ
How much does a custom developer CRM cost in 2026?
Expect 10,000,000–17,000,000 FCFA for a unit-sales CRM, plus 3,000,000 FCFA for the reservation funnel and 1,500,000 FCFA for mobile-payment integration (plus 1.5% per transaction).
Why not just assemble existing SaaS tools?
A patchwork costs 150,000–400,000 FCFA/month but leaves gaps between leads, reservation and payment. Those gaps lose sales the build removes.
Is mobile payment really embedded in the funnel?
Yes, the buyer reserves and pays the deposit in the same journey, at a 1.5% fee per transaction. That cuts time to reserve a unit by 35%.
What is the delivery timeline?
Between 12 and 18 weeks depending on integrations. The CRM and follow-ups can ship first, the reservation funnel and payment next.
How is the +28% conversion measured?
By comparing lead-to-reservation conversion before and after, at equal lead volume. The CRM automates follow-ups and stabilises tracking, which explains the gain.
