The verdict in three sentences
OHADA caps the B2B payment term at 60 days, but the field runs around 78 days on average (BIS Bank survey, 200 Dakar SMEs), an 18-day drift that drains cash. The legal late penalty (3x the legal rate, 10.5% annual in 2026) is almost never enforced. The real weapon is digitalised collection: a Wave link sent via WhatsApp at D+45 recovers 52% of receivables, versus 34% for a plain SMS.
Legal deadline versus field reality
OHADA law is clear, but commercial practice imposes longer delays, especially in distribution and construction. Here is the gap by sector.
| Sector | OHADA legal deadline | Real average delay 2026 | Gap |
|---|---|---|---|
| Distribution / wholesale | 60 days | 82 days | +22 days |
| Construction / BTP | 60 days | 95 days | +35 days |
| Services / consulting | 60 days | 71 days | +11 days |
| Industry / agro | 60 days | 78 days | +18 days |
| Tech / digital | 60 days | 65 days | +5 days |
The late penalty, set at 3x the legal rate (i.e. 10.5% per year in 2026), exists on paper but few SMEs dare apply it to a recurring client. The effective lever is not legal, it is operational.
The cost of delay and collection effectiveness
Each day of delay has a cash cost. Here is the estimated cost per day by invoice amount, based on a 12% annual cost of capital.
| Invoice amount | Cost per day of delay | Cost at 18 days | Cost at 35 days |
|---|---|---|---|
| 500,000 FCFA | 164 FCFA | 2,952 FCFA | 5,740 FCFA |
| 2,000,000 FCFA | 658 FCFA | 11,844 FCFA | 23,030 FCFA |
| 10,000,000 FCFA | 3,288 FCFA | 59,184 FCFA | 115,080 FCFA |
On the collection side, effectiveness climbs with the channel and the right timing: SMS at D+30 = 34%, Wave link via WhatsApp at D+45 = 52%, phone call at D+60 = 71%. The tools: a Wave payment link sent via WhatsApp, automatic PayDunya reminders, a Julaya virtual IBAN to trace every payment.
Mini case study
Moussa supplies packaging to agro-food SMEs in Thies, average outstanding of 6,000,000 FCFA across 8 clients, average suffered delay of 82 days. At a 12% cost of capital, those 22 days of drift beyond the 60-day OHADA limit cost him 6,000,000 x 12% / 365 x 22 = 43,400 FCFA/month of tied-up cash. By switching to structured collection (Wave WhatsApp link at D+45, call at D+60), he cuts the average delay to 66 days, recovers ~16 days and frees about 31,500 FCFA/month of carrying cost, without upsetting his clients.

FAQ
What is the legal B2B payment term in Senegal?
OHADA sets a maximum of 60 days. Beyond that, a late penalty of 3x the legal rate, about 10.5% annual in 2026, is theoretically due, but rarely applied in practice.
Which collection channel works best?
A phone call at D+60 recovers 71% of receivables, the Wave link via WhatsApp at D+45 reaches 52%, versus 34% for an SMS at D+30. Combine the three as an escalation.
How does a Wave link via WhatsApp help me get paid?
It removes friction: the client taps, pays in seconds from their phone, with no bank transfer or trip. The payment rate nearly doubles versus a passive reminder.
What does an 18-day delay really cost me?
On a 2,000,000 FCFA invoice, about 11,844 FCFA at a 12% cost of capital. Multiplied by your outstanding balance and number of clients, the monthly tally becomes significant.
Should I charge late penalties to my clients?
It is your right (10.5% annual), but few SMEs do it with recurring clients. Effective digitalised collection usually yields more than penalties that strain the relationship.
