The verdict in three sentences
The number-one cause of returns on auto parts is the compatibility error: the right reference for the wrong model. A catalog that filters by make, model, year and OEM reference across 50,000+ parts, with real-time stock, brings the return rate down from 15-20 % to under 5 %. Against the Colobane market, the differentiator is not price but the certainty of having the right part, delivered in 24-48h.
The compatibility search funnel
The heart of the site is the vehicle selection engine. Each step eliminates incompatible references and prevents error.
| Step | Filter applied | Remaining references (example) | Error risk |
|---|---|---|---|
| Make | Toyota | 12,000 | high |
| Model | Hilux | 2,400 | medium |
| Year / generation | 2015-2020 | 850 | low |
| Category | Braking | 60 | very low |
| Verified OEM reference | front pads | 1 | none |
At the end of the funnel, the customer sees a single part guaranteed compatible: zero ambiguity, zero returns.
Stock, delivery and price positioning
Service beats raw price. Here are the 2026 orders of magnitude against a physical-market purchase.
| Criterion | Online catalog | Colobane market |
|---|---|---|
| Compatibility check | automatic (OEM) | verbal, risky |
| Availability shown | real-time stock | check on site |
| Lead time | 24-48h delivered | immediate if in stock |
| Warranty | 3-12 months tracked | rare or verbal |
| Return rate | < 5 % | unmanaged |
| Estimated average basket | 35,000-80,000 FCFA | variable |
| Payment | Wave / Orange Money / on delivery | cash |
The site does not replace the urgency of immediate breakdown repair, but captures planned purchases and B2B fleets that want traceability.

Ibrahima runs an auto parts business in Dakar and goes online with 6,000 active references. Before, out of 200 monthly sales, 18 % came back for incompatibility, meaning 36 returns to handle and around 540,000 FCFA of tied-up stock. With the OEM filter, the rate drops to 4 %, meaning 8 returns. He saves 28 returns a month in logistics and disputes, and his average basket rises from 32,000 to 41,000 FCFA thanks to suggested complementary parts. On 200 sales at 41,000 FCFA, that is 8,200,000 FCFA of monthly revenue, versus 6,400,000 FCFA before.
FAQ
How do you get compatibility data on 50,000 references?
We import OEM databases in batches (supplier CSV/Excel) and link them to the vehicle selection engine. Initial entry is the main effort; afterward updates happen through incremental imports.
Is real-time stock complicated?
Not if inventory is kept up to date. The catalog syncs with your stock file or POS software to automatically show "in stock", "on order" or "out of stock".
Can you sell to garages and fleets in B2B?
Yes. We add pro accounts with negotiated pricing, bulk orders and invoicing, which secures recurring volume far more stable than individual buyers.
How much does such a catalog cost?
As a 2026 order of magnitude, a vertical e-commerce platform with a compatibility engine and real-time stock ranges between 2,000,000 and 4,000,000 FCFA depending on the number of references and integrations.
