The verdict in three sentences
In auto spare parts, the problem isn't price but compatibility: buying the wrong part wastes time and money and drives 15% of returns. A vertical marketplace with make / model / year search and a reliable compatibility filter cuts those returns by about 60%. With an average basket of 25,000-80,000 FCFA and an 8-12% commission, the model is highly profitable once the compatibility catalog is solid.
Why compatibility changes everything
The customer's nightmare is ordering a part that doesn't fit. A filter by vehicle (make, model, year, engine) transforms the experience: the customer enters their vehicle once and only sees guaranteed-compatible parts. This cuts returns, builds trust, and lifts the average basket because customers dare to order technical parts.
The marketplace aggregates several sellers (scrapyards, importers, specialist shops) on one reference, creating competition on price and lead time. Here are the 2026 order-of-magnitude figures:
| Metric | 2026 target | Comment |
|---|---|---|
| Average basket | 25,000 – 80,000 FCFA | Technical parts, often 1-3 refs |
| Platform commission | 8 – 12% | Thinner seller margin than fashion |
| Revenue per transaction | 2,500 – 8,000 FCFA | Basket × commission |
| Return rate without filter | ~15% | Incompatible part |
| Return rate with filter | ~6% | ~60% drop |
| Sellers per popular reference | 3 – 8 | Price / lead-time competition |
Warranty, returns and trust
The second trust lever is the warranty. A new part should be covered 3-12 months depending on type; a used scrapyard part, 15-30 days. The platform centralizes the return policy so each seller doesn't impose its own rules.
| Part type | 2026 warranty | Return policy |
|---|---|---|
| New OEM part | 6 – 12 months | Return in 14 days if unfitted |
| New aftermarket part | 3 – 6 months | Return in 7 days if sealed |
| Used part (scrapyard) | 15 – 30 days | Exchange if defect confirmed |
| Consumables (filters, oil) | None | No return once opened |
| Incompatible part (filter error) | — | Free return at platform cost |
The compatibility filter isn't just convenience: it decides who pays for the return. If the error comes from the filter, the platform refunds — hence the importance of a clean vehicle database.
Mini case study
Moussa builds an auto-parts marketplace in Nairobi with 40 sellers. He targets 1,500 transactions per month at a 45,000 FCFA average basket, i.e. a GMV of 67,500,000 FCFA. At 10% commission, gross revenue reaches 6,750,000 FCFA per month. Before the compatibility filter, 15% of sales came back as returns, half at the platform's expense — a cost of about 750,000 FCFA/month. After deploying the filter, returns fall to 6%, saving nearly 450,000 FCFA monthly and sharply improving satisfaction.

FAQ
How do you build the vehicle compatibility database?
Start with the most common models on the local market (Toyota, Hyundai, Peugeot, Mercedes) and enrich the database reference by reference. A good base covers 80% of searches with the 200 most common models.
What commission is realistic on auto parts?
Between 8 and 12%. Seller margins are thinner than in fashion, so above 12% sellers push back. High volume and basket size offset the lower rate.
How do you handle multiple sellers on the same part?
One product page per reference, with seller offers ranked by price, lead time and rating. The customer picks an offer, the order is routed to the right seller, and the payment split is automatic.
Who covers returns for incompatibility?
If the error comes from the platform's compatibility filter, the platform pays the return. If the customer picked the wrong vehicle, they cover it. Hence the value of a reliable filter.
How much does this kind of marketplace cost?
A Growth tier (unlimited sellers, KYC, weekly payouts, compatibility filter) runs between 5,000,000 and 7,000,000 FCFA. The vehicle filter is what sets a genuinely useful tool apart from a plain marketplace.
