The verdict in three sentences
As soon as you sell across several channels (physical store, site, Instagram, WhatsApp) without unified stock, you sell the same item twice: that is an oversell, between 4 and 9 % of orders. Real-time synced stock updates every storefront in under 2 minutes and cuts stockout cancellations by 70 %. The tool costs 15,000 to 45,000 FCFA/month, a fraction of the revenue lost to disappointed customers.
Siloed stock or synced stock
Siloed stock means one counter per channel, kept by hand. A sale on one channel does not inform the others, hence oversells and "phantom stockouts" (item shown out of stock while it sits in-store). Synced stock centralizes a single truth and pushes it everywhere.
| Criterion | Siloed stock | Synced stock |
|---|---|---|
| Oversell rate | 4-9 % | < 1 % |
| Phantom stockouts | 6-12 % | < 2 % |
| Update delay | manual, hours | < 2 min |
| Monthly stocktake time | baseline | -50 % |
| Stockout cancellations | baseline | -70 % |
| Monthly tool cost | 0 FCFA | 15,000-45,000 FCFA |
| Human error risk | high | low |
The tool cost is marginal against the hidden cost of a customer who gets a "sorry, out of stock" after paying.
Frequency and risk by channel
Not all channels move at the same pace or risk. The physical store empties stock without a digital trace; Instagram creates sudden spikes on a viral post.
| Channel | Sales frequency | Oversell risk | Sync priority |
|---|---|---|---|
| Physical store | continuous during day | very high | critical |
| E-commerce site | continuous | high | critical |
| Instagram Shopping | in spikes | high | high |
| WhatsApp Business | irregular | medium | high |
| Third-party marketplace | continuous | medium | medium |
Top priority goes to the two channels that empty stock continuously: the store till and the site. If those two do not share one counter, everything else drifts.
Mini case study
Kouassi runs a sneaker shop in Osu, Accra, plus a site and an Instagram account. Without sync, he suffers 7 % oversells on 220 orders/month, about 15 cancelled orders. Average basket 38,000 FCFA: that is ~570,000 FCFA of lost sales and annoyed customers. He installs a sync tool at 30,000 FCFA/month. Oversells drop to 1 % (~2 orders); he recovers ~13 sales, roughly 494,000 FCFA/month for a 30,000 FCFA cost. The return is immediate in month one, not counting stocktake time cut in half.

FAQ
What is a phantom stockout?
An item shown "out of stock" online while it remains in-store, or the reverse. Without sync they hit 6 to 12 % of the catalog and drive customers away for nothing.
How much does a sync tool cost?
Between 15,000 and 45,000 FCFA/month depending on channels and references. It is negligible against sales lost to oversells.
How fast does stock update?
With a good integration, in under 2 minutes after each sale on any channel. That delay is what eliminates oversells.
Do I have to stop everything to install sync?
No. Channels connect one by one, starting with the store till and the site, the two riskiest. The switch happens without closing the shop.
What if I also sell on WhatsApp?
WhatsApp Business links to the same central stock. Each confirmed order decrements the single counter, like every other channel.
