The verdict in three sentences
A semi-wholesale trader at Ocass market does not lose money on sales, he loses it on the tabs: the paper credit book is the real black hole of the business. A POS app that tracks every customer receivable, sends SMS reminders and shows outstanding balances in real time recovers 20 to 30 % of bad debt normally written off. The choice is between a custom build (1,500,000 to 2,800,000 FCFA) paid back within a year and a monthly SaaS (12,000 to 25,000 FCFA/month) that is lighter to start.
Paper book versus a POS with credit
The problem is simple: a wholesaler sells to retailers who rarely pay cash. The tab piles up, nobody knows who owes what, and part of the balance becomes a dead loss. Here is what a POS built for semi-wholesale changes.
| Criterion | Paper book (tab) | POS + credit app |
|---|---|---|
| Outstanding credit visible | No, manual math | Yes, real time per customer |
| Average balance tracked | 3,000,000–8,000,000 FCFA opaque | 3,000,000–8,000,000 FCFA tracked |
| Bad-debt reminders | None / by feel | Auto SMS at D+7, D+15 |
| Bad-debt reduction | Baseline | −20 to −30 % |
| Typical B2B ticket | 25,000–400,000 FCFA | 25,000–400,000 FCFA |
| Customer history | Lost if book lost | Saved, exportable |
| End-of-day close | 30–45 min | 2–3 min |
Cost and timeline
Two models compete. The custom build belongs to the trader with no monthly rent; the SaaS starts fast but is paid every month.
| Item | Custom build | Monthly SaaS |
|---|---|---|
| Upfront cost | 1,500,000–2,800,000 FCFA | 0–50,000 FCFA setup |
| Recurring cost | Hosting 15,000–30,000 FCFA/mo | 12,000–25,000 FCFA/mo |
| Time to launch | 5–8 weeks | 3–7 days |
| Credit module | Custom, fits the tab | Standard, sometimes limited |
| SMS reminders | Included (SMS cost extra) | Depends on plan |
| Code ownership | Yes, to the client | No |
| 3-year cost (ballpark) | ~2,500,000–3,500,000 FCFA | ~700,000–1,100,000 FCFA |
Short term the SaaS is cheaper; beyond 3–4 years, or when you need a truly specific credit flow, the custom build becomes rational.
Mini case study
Serigne, a goods wholesaler at Ocass market, carries a credit balance of about 5,000,000 FCFA spread over 60 retailers. Each year he estimates losing 8 % to bad debt, i.e. 400,000 FCFA. After installing a POS with automatic SMS reminders at D+7 and D+15, his bad debt drops to 5.5 %, i.e. 275,000 FCFA: 125,000 FCFA recovered per year. With a SaaS plan at 20,000 FCFA/month (240,000 FCFA/year), the tool does not yet pay for itself on bad debt alone — but add the tenfold faster close and the end of customer disputes, and the equation turns clearly positive in year one.

FAQ
Does the app work without an Internet connection?
Yes, a well-built POS runs offline-first and syncs as soon as 4G returns. That is essential in a market where the network drops. Target sync latency is under 5 seconds after reconnection.
How much do reminder SMS cost?
Roughly 15 to 25 FCFA per SMS depending on carrier and volume. For 60 customers reminded twice a month, that stays under 3,000 FCFA/month, easily covered by recovered debt.
Can several sellers share the same POS?
Yes. Each seller has a login, with sales and credit balances tracked separately, plus a consolidated dashboard for the owner. Useful from 2–3 employees onward.
Custom build or SaaS to start?
If you are testing the concept, start on SaaS (12,000–25,000 FCFA/month). If your credit flow is very specific and you want to own the tool, the custom build (1,500,000–2,800,000 FCFA, delivered in 5–8 weeks) is the right call.
