The verdict in three sentences
An order-taking bot on the WhatsApp Business API costs 4,000,000 to 10,000,000 FCFA depending on scope: catalogue, cart, per-customer pricing and ERP synchronisation. Meta fees stay low, around USD 0.01 to 0.05 per template message depending on country and category, and replies within the 24-hour service window opened by the retailer are free. For a distributor receiving 900 orders a week, the bot removes manual entry for about 70 % of orders and pays for itself in 5 to 7 months.
What the bot does and what it costs
The retailer messages the distributor's official number. The bot identifies them by phone number, shows their catalogue and negotiated prices as lists and buttons, builds the cart, checks the credit limit, then pushes the validated order into the ERP. Unusual orders are handed to a sales rep in the same conversation.
| Scope | Included features | 2026 budget | Timeline |
|---|---|---|---|
| Essential | Catalogue, cart, summary, order export to Excel or dashboard | 4,000,000 to 5,000,000 FCFA (EUR 6,100 to 7,600) | 6 to 8 weeks |
| Standard | Essential + per-customer pricing, credit limit, history, ERP sync (Sage, Odoo) | 6,000,000 to 7,500,000 FCFA (EUR 9,150 to 11,450) | 8 to 12 weeks |
| Advanced | Standard + targeted promotions, delivery tracking, Wave and Orange Money payment, voice note transcription | 8,500,000 to 10,000,000 FCFA (EUR 12,950 to 15,250) | 12 to 16 weeks |
| Option: sales back office | Conversation takeover, stats per rep and per area | 800,000 to 1,500,000 FCFA | 2 to 3 weeks |
| Option: driver app | Signed delivery notes, cash collection | 1,500,000 to 2,500,000 FCFA | 3 to 4 weeks |
The most underestimated item is ERP synchronisation: item codes, pack sizes (crate, pack, pallet), customer discounts and available stock must be reliable, otherwise the bot offers out-of-stock products. Plan 2 to 3 weeks of data cleaning before launch.
Monthly running costs
Assumption: 1,800 active retailers, 3,900 orders a month, USD 1 ≈ 600 FCFA (2026 order of magnitude).
| Monthly item | Volume | Estimated cost |
|---|---|---|
| Replies within the 24-hour service window | 3,900 orders and their confirmations | Free on Meta's side |
| Utility messages outside the window (reminders, delivery notices) | 2,000 messages × USD 0.02 | About 24,000 FCFA |
| Marketing messages (weekly promotions) | 1,800 × 4 sends × USD 0.04 | About 173,000 FCFA |
| Hosting, database, monitoring | Cloud server and backups | 50,000 to 150,000 FCFA |
| Maintenance and minor changes | 1 to 2 days a month | 150,000 to 300,000 FCFA |
| Monthly total | n/a | 400,000 to 650,000 FCFA |
Meta rates vary by recipient country and message category; check the current rate card at launch. Using Meta's Cloud API directly avoids the fees of an intermediary provider, often USD 30 to 80 a month.
Before and after the bot
| Indicator | Voice orders keyed in manually | WhatsApp bot |
|---|---|---|
| Entry time per order | 4 to 6 minutes | 0 for 70 % of orders |
| Entry hours per week (900 orders) | 60 to 90 hours | 18 to 27 hours |
| Error rate (item, quantity, customer) | 5 to 8 % | 1 to 2 % |
| Confirmation time to the retailer | 2 to 6 hours | Immediate |
| Orders received after office hours | Processed the next day | Processed around the clock |
| Sales visibility | Notebooks and spreadsheets | Dashboard by area and product |
Retailers do not drop voice notes overnight. Successful rollouts start with the 300 most active retailers, a 5-minute walkthrough by the field sales rep and a 1 to 2 % launch discount on orders placed through the bot for one month.

- Standard bot: 6,500,000 FCFA, running at 450,000 FCFA a month.
- 70 % of entry removed: two operators reassigned to collections, i.e. 600,000 FCFA a month of freed time.
- Errors cut from 6 % to 1.5 %: 3,900 × 4.5 % × 5,000 FCFA cost per error (redelivery, credit note) = 877,500 FCFA a month.
- Net gain: 600,000 + 877,500 − 450,000 = 1,027,500 FCFA a month.
Payback: 6,500,000 ÷ 1,027,500 ≈ 6.3 months, not counting the night-time orders now captured.
FAQ
Do we need a new WhatsApp number?
The number must be registered on the WhatsApp Business API and can no longer be used in the regular app. Meta Business account verification usually takes 1 to 3 weeks.
Does the bot understand voice notes?
The bot mainly guides retailers with buttons and lists, which covers 70 % of orders. Automatic transcription of voice notes in Wolof and French is an option, at 1,000,000 to 1,500,000 FCFA, with accuracy to be validated on your products.
Which ERP can be connected?
Sage, Odoo, SAP Business One or a local system with an API or an accessible database. Without an API, a file sync every 15 minutes is still possible, for 500,000 to 1,000,000 FCFA extra.
How much do Meta messages cost for 4,000 orders a month?
Conversations opened by the retailer are free for 24 hours. Only template messages outside the window are billed, about 25,000 to 200,000 FCFA a month depending on your reminders and promotions.
Can retailers pay with Wave or Orange Money?
Yes, in the Advanced scope: the bot sends a payment link and the ERP marks the invoice paid on confirmation, usually in under a minute.
