The verdict in three sentences
A B2B ordering portal wired to your ERP lets your professional customers order on their own, 24/7, with their negotiated prices and their history. In 2026 in Douala, budget 8M to 25M FCFA for the portal, plus 3M to 8M FCFA for the EDI/ERP connector. The ROI comes from a 70% cut in manual data entry and the end of orders lost over email or WhatsApp.
What a self-service ordering portal contains
The heart of the system is not the catalog: it is recognizing the logged-in customer, their prices, their quotas and their history. Here are the features that justify the investment.
| Feature | Purpose | Effort (days) | 2026 ballpark |
|---|---|---|---|
| Customer accounts with negotiated prices | Each pro sees THEIR prices | 10-16 | 2.5M-4.5M FCFA |
| One-click recurring order | Instant reorder | 6-10 | 1.5M-3M FCFA |
| Real-time stock (ERP) | No surprise stockouts | 8-14 | 2M-4M FCFA |
| Outstanding balance and credit limits | Risk control | 6-10 | 1.5M-3M FCFA |
| History + delivery notes | Self-service support | 5-8 | 1.2M-2.5M FCFA |
| EDI connector (large customers) | Automated exchange | 12-20 | 3M-8M FCFA |
Cost lines and local day rate
The budget depends on the number of integrations and your ERP's complexity. In Douala, a senior developer's day rate runs between 200,000 and 350,000 FCFA in 2026, which makes custom builds competitive against foreign SaaS licences billed in euros.
| Line item | 2026 range (FCFA) | Comment |
|---|---|---|
| Design & UX | 1.5M-3M | Workshops, mockups, journeys |
| Portal development | 5M-14M | Accounts, prices, orders, stock |
| EDI/ERP connector | 3M-8M | APIs, mapping, testing |
| QA & go-live | 1M-2.5M | Testing, team training |
| Annual maintenance | 15% of build | Fixes, evolutions, hosting |
Measurable productivity gains
The real argument is the sales time recovered. Every manually keyed order takes 8 to 12 minutes; multiplied by hundreds of monthly orders, the hidden bill is heavy.
| Metric | Before portal | After portal | Gain |
|---|---|---|---|
| Manual entry per order | 10 min | 3 min | -70% |
| Orders outside business hours | 0% | 25-35% | Extra sales |
| Entry errors | 6-8% | <1% | Fewer credit notes |
| Sales time/day | baseline | -2 h | Refocused on selling |
Mini case study
Mr. Fotso runs an electrical supplies distributor in Douala, with 220 reseller customers and 4 reps keying orders received by phone and WhatsApp. He invests 13M FCFA in a portal wired to his ERP, plus 4.5M FCFA for the EDI connector of his 3 biggest customers. Six months later, 55% of orders go through the portal, 30% of them outside office hours. The data-entry gain is about 1.5 FTE, nearly 6M FCFA per year, and the investment pays back in just over two years, not counting the recovered night and weekend sales.

FAQ
Is a custom portal more cost-effective than a foreign SaaS?
Often yes in Douala: a B2B SaaS billed in euros quickly costs 15,000 to 40,000 EUR/year, whereas a custom build amortized over 4-5 years is cheaper and remains your property.
Should all customers be connected via EDI?
No. EDI only concerns your largest accounts that require it. For everyone else, the web portal is enough and far cheaper.
How long until go-live?
Allow 3 to 5 months depending on ERP complexity and the number of integrations. A portal MVP without EDI can ship in 3 months.
What if my ERP is old?
We build an exchange layer (API or files). That adds 1M to 3M FCFA but stays largely profitable against double-entry errors.
Does the portal work on mobile over 3G?
Yes, provided it is built lightweight. That is essential in Cameroon: most of your customers will order from their phone.
