The verdict in three sentences
In Abidjan, a services SME that lets invoices drag on for more than 90 days is financing its clients with its own bank overdraft. An automated reminder sequence by email, SMS and WhatsApp, plugged into invoicing and paired with a mobile payment link, costs FCFA 2,500,000 to 6,000,000 in 2026 (about EUR 3,800 to 9,150). The realistic outcome is DSO cut from 92 to 61 days in 6 months, freeing hundreds of millions of FCFA in cash for a mid-sized SME.
Why manual reminders fail
In most Ivorian SMEs, collections rely on one person who calls clients when time allows. Reminders go out late, with no history, and payment promises obtained by phone are tracked nowhere.
| Observed problem | Consequence | Automation response |
|---|---|---|
| First reminder at day 30 or later | The client has already prioritised other suppliers | Automatic reminder at day -3 and day +1 |
| Phone-only reminders | 40 to 60% of calls unanswered | Email, SMS then WhatsApp sequence |
| No way to pay immediately | The client postpones payment | Wave, Orange Money, MTN MoMo or card link |
| Payment promises not tracked | No follow-up on the promised day | Promise tracker with alerts |
| No view by client or salesperson | Bad payers keep being served | Scoring and blocking of new orders |
| Late formal notice | Costly legal collection | Automatic escalation at day 45 |
The standard reminder sequence and its sending cost
A good sequence combines channels according to the delay and the client profile. Unit costs below are 2026 orders of magnitude in Côte d'Ivoire.
| Step | Channel | Content | Indicative unit cost |
|---|---|---|---|
| Day -3 | Polite reminder, invoice attached, payment link | Close to zero | |
| Day +1 | SMS | Due date passed, mobile payment link | FCFA 15 to 25 |
| Day +7 | WhatsApp Business | Personalised message, payment button | FCFA 20 to 50 |
| Day +15 | Call from the collections officer | Script, payment promise logged | 10 minutes of internal time |
| Day +30 | Email + WhatsApp from the CFO | Firm tone, instalment plan offered | FCFA 20 to 50 |
| Day +45 | Formal notice letter | Generated automatically, approved by the CFO | FCFA 2,000 to 5,000 (delivery) |
For 480 clients and about 900 invoices a month, SMS and WhatsApp sending costs stay below FCFA 60,000 a month.

Maintenance and hosting run at FCFA 75,000 to 200,000 a month. Go-live takes 6 to 10 weeks, with a pilot on 50 clients before full rollout.

- Investment: FCFA 4,500,000, plus FCFA 150,000 a month for maintenance and FCFA 60,000 a month for messaging.
- DSO cut to 61 days in 6 months: 31 days x 10,000,000 = FCFA 310,000,000 of cash freed.
- Overdraft cost avoided at 10% a year: about FCFA 31,000,000 a year.
- Annual running cost: (150,000 + 60,000) x 12 = FCFA 2,520,000.
Net annual gain: 31,000,000 - 2,520,000 = FCFA 28,480,000. The project pays back in under 2 months once DSO has stabilised, before counting fewer bad debt write-offs.
FAQ
How much does reminder automation cost for an SME in Abidjan?
In 2026, budget FCFA 2,500,000 to 6,000,000 depending on the invoicing software and number of channels. Add FCFA 75,000 to 200,000 a month for maintenance plus SMS and WhatsApp sending costs.
Can clients pay directly from the reminder?
Yes, each message contains a Wave, Orange Money, MTN MoMo, Moov Money or card payment link. The payment is matched to the invoice automatically, which stops the reminder sequence in under a minute.
Won't WhatsApp reminders annoy our clients?
Tone and frequency are set by segment: a strategic client gets a polite reminder and a call, a high-risk client a tighter sequence. In practice, fewer than 2% of clients ask to stop receiving messages.
What results can we expect, and how fast?
The first effects appear in the first month, with DSO down 10 to 15 days. A 25 to 35% DSO reduction, for example from 92 to 61 days, is typically achieved within 6 months.
Do we need to change our invoicing software?
No, the reminder engine connects to Sage, Odoo, local software or a simple daily Excel export. The connector accounts for FCFA 500,000 to 1,200,000 of the budget.
