The verdict in three sentences
A B2B spare parts marketplace in Dubai is a complex application: local agencies typically quote AED 250,000 to 700,000 in 2026 (market estimate), and Kolonell's complex application tier sits at 7,000,000 to 15,000,000 FCFA (10,670 to 22,870 EUR), for 16 to 24 weeks of work. The core value is not the storefront but OEM part number search (part numbers, VIN, cross-references), because a workshop that cannot find the right part in 30 seconds calls its usual supplier. A 5 to 12 % commission on realistic volume pays back the platform in 18 to 30 months if importer onboarding is treated as a full sales project.
What the platform must do, and what each module costs
Dubai is a regional re-export hub for auto parts, with dense trading clusters around Deira and Al Quoz serving the Gulf, East Africa and South Asia. The technical difficulty lies in the catalogue: the same brake pad exists under 6 to 15 part numbers depending on the manufacturer. Without a cross-reference table, the marketplace shows duplicates and loses workshop trust.
| Module | Scope | Share of budget (estimate) | Indicative timeline |
|---|---|---|---|
| Catalogue and cross-references | OEM and aftermarket numbers, fitment by model and year | 20 to 25 % | 4 to 6 weeks |
| Search | By part number, VIN, model, typo tolerance, Arabic and English | 12 to 15 % | 2 to 3 weeks |
| Importer portal | Excel stock import, prices, photos, delivery times | 15 to 18 % | 3 to 4 weeks |
| Workshop portal | Quotes, recurring orders, history, trade credit | 12 to 15 % | 2 to 3 weeks |
| Payments and commissions | Cards, bank transfer, vendor and platform split, statements, VAT invoices | 15 to 18 % | 3 to 4 weeks |
| Logistics | Pickup, courier delivery, tracking, proof of delivery | 8 to 10 % | 2 weeks |
| Back office | Moderation, disputes, KPIs, accounting export | 8 to 10 % | 2 weeks |
Workstreams overlap, hence a total of 16 to 24 weeks rather than the raw sum. An MVP limited to the catalogue, part number search and ordering with online payment can go live around week 12 with 10 to 15 pilot importers.
Business model: commission, subscription or both
The revenue model drives part of the build (vendor invoicing, statements, payouts). Here are the options seen on B2B marketplaces in 2026, as market estimates.
| Model | Rate or price (2026 estimate) | Advantage | Limitation |
|---|---|---|---|
| Commission only | 5 to 12 % per order | No barrier to sign-up | Low revenue at launch |
| Vendor subscription | AED 150 to 600 per month | Predictable revenue | Deters small importers |
| Hybrid | 3 to 6 % plus AED 100 to 300 per month | Balances volume and recurrence | More rules to code |
| Paid listings | AED 30 to 200 per product per month | High margin | Useful only after 1,000 orders a month |
| Delivery fees | AED 15 to 40 per drop in Dubai | Covers logistics | Requires reliable couriers |
| Workshop credit (with a partner) | 1 to 3 % fee | Raises basket size | Default risk to manage |
On low-margin parts (filters, pads), a commission above 8 % pushes importers to sell off-platform. Many projects therefore use a sliding commission: 10 % below AED 50,000 of monthly sales per vendor, 6 % above.
The risks that derail the budget
Three topics blow up quotes when discovered mid-project. First, data quality: importers often run stock in Excel or legacy ERPs, so you need a tolerant import tool and a few days of assisted data entry. Second, split payments: automatically paying out the vendor share requires clear rules on returns, disputes and 5 % UAE VAT on commissions. Third, multilingual UX: Arabic, English and often Urdu or Hindi labels, with right-to-left layout for Arabic.
Post-launch maintenance follows Kolonell's grid: 35,000, 75,000 or 120,000 FCFA per month (Basic, Standard, Premium). For an active marketplace, Premium is the sensible level.
Mini case study
Illustrative example: Omar, a founder in Dubai, brings together 50 importers and targets 2,000 workshops. He sets a budget of AED 450,000, mid-range for the local market. At 12 months, he projects 600 active workshops placing 2 orders a month averaging AED 1,200, i.e. AED 1,440,000 in monthly volume.

- Average commission of 7 %: AED 100,800 per month.
- Monthly costs (maintenance, hosting, 2 field sales reps, support): about AED 55,000.
- Monthly margin: about AED 45,800.
The build pays back in roughly 10 months once that volume is reached. In practice ramp-up takes 8 to 12 months, so payback lands closer to 18 to 24 months after launch.
FAQ
Can we start below AED 250,000?
Yes, an MVP without logistics or workshop credit can fit Kolonell's medium application tier, 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR). The platform is then limited to 10 to 15 importers and part number search.
Do we need a native mobile app?
Not at first: an installable PWA covers 90 % of a workshop's needs and avoids 30 to 40 % of extra cost. A native app makes sense after 5,000 active users.
How do we handle used parts without a part number?
Add a free-form listing with mandatory photos and the make, model and year of the donor vehicle. These listings often account for 20 to 40 % of the catalogue in re-export markets.
Who carries the risk if a part does not fit?
Terms must set a return window, for example 72 hours, and hold the vendor payout in escrow during that period. The disputes module is about 5 % of the budget.
How long until profitability?
As an estimate, 18 to 30 months depending on onboarding speed. The main lever is sales: a visited workshop converts 3 to 5 times better than one contacted by email.
