The verdict in three sentences
Running an SME on Excel files swapped over WhatsApp means losing data, duplicating it and having no real-time view. A web business app centralizes stock, customers and orders, with mobile access and offline mode for unstable-connection areas. Budget 2 to 8 million FCFA (about 3,000-12,000 EUR) and 8 to 14 weeks for a custom tool in 2026, paid back by 20 to 50 hours saved per month.
The hidden cost of a shared spreadsheet
A spreadsheet looks free, but every stock error, every duplicate entry and every "which is the right version?" costs time and money. For an SME of 10 to 30 people, this cost often exceeds 400,000 to 900,000 FCFA/month.
| Excel risk item | Typical SME frequency | Estimated monthly cost (FCFA, 2026) |
|---|---|---|
| Stock / entry errors | 10 to 25 / month | 150,000 to 350,000 |
| Version reconciliation | 15 to 30 h / month | 120,000 to 300,000 |
| Lost / unfindable data | 2 to 5 incidents | 60,000 to 150,000 |
| No real-time visibility | permanent | 100,000 to 250,000 |
| Total hidden cost | — | 430,000 to 1,050,000 |
These are 2026 orders of magnitude; they rise with the number of people editing the same files.
Budget for a web business app
Price depends on business complexity and data volume to migrate. Cloud hosting and mobile/offline access are line items to plan from the start.
| Item | 2026 range (FCFA) | Timeline |
|---|---|---|
| Scoping + specs | 300,000 to 700,000 | 1 to 2 weeks |
| Business app development | 1,500,000 to 5,500,000 | 6 to 10 weeks |
| Data migration | 500,000 to 1,500,000 | 1 to 3 weeks |
| Training + acceptance | 300,000 to 800,000 | 1 week |
| Cloud hosting | 40,000 to 120,000 / month | recurring |
| Full project | 2,000,000 to 8,000,000 | 8 to 14 weeks |
The app is yours: no per-user subscription that explodes as the team grows.
Shared spreadsheet or web app?
The real comparison is not entry price but reliability, visibility and mobile access for teams working in the field.
| Criterion | Shared spreadsheet (WhatsApp) | Web business app |
|---|---|---|
| Multi-user access | version conflicts | real-time |
| Mobile / offline access | no | yes |
| Stock / sales visibility | delayed | instant |
| Traceability | none | full log |
| Entry errors | frequent | -50 % (controls) |
| Backups | manual | automatic (cloud) |

Koffi, manager of a distribution SME in Nairobi (18 staff), tracks stock and orders across five Excel files shared over WhatsApp. He estimates 28 hours/month lost to reconciliation and 18 stock errors/month at about 12,000 FCFA impact each, a hidden cost near 700,000 FCFA/month. A web business app at 4,500,000 FCFA (migration included) plus 80,000 FCFA/month hosting removes 60 % of that cost, about ~420,000 FCFA/month saved and a payback in ~11 months, before the real-time visibility that prevents stockouts.
FAQ
Does the app work without a good connection?
Yes, offline mode lets you enter data on mobile then sync when the network returns. It is essential for field teams and unstable-3G areas.
How much is hosting each month?
Allow 40,000 to 120,000 FCFA/month depending on volume and user count, automatic backups included. It is predictable, unlike Excel-related losses.
Can we keep Excel alongside?
Yes. The app imports and exports Excel/CSV. Many clients keep Excel for ad hoc analysis and centralize reference data in the app.
How long for migration?
Between 1 and 3 weeks depending on file cleanliness. Prior cleaning and deduplication cost 500,000 to 1,500,000 FCFA but avoid importing years of errors.
Can we pay in installments?
Yes, the project splits into phases (scoping, development, migration) with a schedule. You can also prioritize a first module and spread the budget over 2 to 3 batches.
