The verdict in three sentences
Linking ERP, CRM and invoicing into a single flow costs, in 2026, between 4,000,000 and 11,000,000 FCFA (about 6,100-16,800 EUR) over 5 to 9 weeks. The quote-order-invoice flow moves without re-keying via API and webhooks, instead of juxtaposed, disconnected SaaS. Result: quote-to-invoice time cut by about 70 % and near-zero billing errors.
The scope to define in the blueprint
A good blueprint sets the synchronised flows, the direction of each data field and the reversibility plan. Here is the typical scope and cost per module.
| Module / synced flow | FCFA cost (2026) | Content |
|---|---|---|
| CRM -> ERP (orders) | 900,000 - 2,400,000 | Approved quotes, customers, lines |
| ERP -> Invoicing | 900,000 - 2,400,000 | Invoices, credits, due dates |
| Stock & availability | 700,000 - 1,800,000 | Reservation, stockout alerts |
| Payments & follow-ups | 600,000 - 1,600,000 | Statuses, auto reminders |
| Monitoring & reversibility | 900,000 - 2,800,000 | Monitoring, exports, exit |
| Project total | 4,000,000 - 11,000,000 | 5 to 9 weeks |
Maintenance: 250,000 to 550,000 FCFA/month (flow monitoring, enhancements, support).
Integrated flow vs juxtaposed SaaS
Stacking three disconnected SaaS is cheaper to buy, but every manual transfer costs time and creates errors. Integration removes those breaks.
| Criterion | Custom integrated flow | Juxtaposed SaaS |
|---|---|---|
| Quote -> invoice time | -70 % | Slow, manual |
| Billing errors | Near zero | Frequent |
| Double entry | Removed | Permanent |
| Real-time view | Yes | Fragmented |
| Cost | 4 - 11 M FCFA + maint. | Stacked subscriptions |
| Reversibility | Plan + exports delivered | Scattered data |
Mini case study
Rashid, operations director of a 55-person industrial SME in Dubai, loses time between CRM, ERP and invoicing: a quote takes 5 days to become an invoice, with ~4 % of invoices to correct. He invests 8,000,000 FCFA plus 380,000 FCFA/month. After integration, the quote-to-invoice cycle drops to 1.5 days (-70 %) and errors fall below 0.5 %. On 300 invoices/month at 150,000 FCFA average, cutting errors from 4 % to 0.5 % secures ~1,575,000 FCFA/month of reliable billing and speeds collection. Year-one outlay: 8,000,000 + 4,560,000 = 12,560,000 FCFA, absorbed in under a year by recovered cash and avoided disputes.

Do we have to replace our current software?
No. Integration links your existing ERP, CRM and invoicing tool. We change the plumbing, not the applications.
What is the reversibility plan?
The guarantee to recover your data and disconnect cleanly: documented exports, flow schema, no opaque dependency. It is a blueprint item.
How are duplicate invoices avoided?
Uniqueness rules and shared statuses prevent one order generating two invoices. Monitoring alerts on any discrepancy.
How long to go-live?
5 to 9 weeks depending on the number of flows. We can deliver the CRM->ERP flow first, then invoicing, to secure the cutover.
Does the system scale?
Yes: the API/webhook architecture with a queue absorbs order peaks without loss, unlike manual transfers.
