The verdict in three sentences
A B2B construction supplies marketplace in Dubai, with multi-supplier quotes, secured net-30 payment and site delivery, costs USD 65,000 to 150,000 excl. VAT and takes 6 to 8 months to build. The business model relies on a 3 to 8% commission set by product family, applied to an average basket of about USD 2,700 (AED 10,000). The hard part is not technical: it is onboarding the first 150 suppliers and controlling credit risk on deferred payment.
The 2026 development budget
UAE contractors still buy largely by phone and WhatsApp, comparing quotes by hand. The platform must reproduce that reflex: a site engineer posts a need (500 bags of OPC cement, 12 tonnes of rebar), several suppliers respond, the buyer approves and tracks delivery.
| Module | 2026 range (USD excl. VAT) | Scope |
|---|---|---|
| Multi-supplier catalogue and spec sheets | 10,000 to 19,000 | Families, units (tonne, m³, pallet), standards |
| Multi-supplier request for quote | 13,000 to 28,000 | Express tender, comparison, negotiation |
| Supplier portal and KYC | 9,000 to 18,000 | Trade licence, TRN, stock, delivery zones |
| Payments, escrow and net 30 | 14,000 to 34,000 | Cards, bank transfer, guaranteed deferred payment |
| Logistics and site delivery | 9,000 to 25,000 | Slots, geolocation, signed delivery note |
| Site engineer mobile app | 10,000 to 26,000 | Order and receive from the site |
| Total | 65,000 to 150,000 | 6 to 8 months |
Running costs sit between USD 3,000 and 6,000 per month: hosting, corrective maintenance, supplier support, SMS and WhatsApp Business API fees, excluding the sales team.
Setting commissions by product family
A flat 5% commission does not work in construction: margins on cement and steel are thin, while hardware and tools can bear more. The grid below is a realistic 2026 starting point.
| Family | Typical supplier margin | Recommended commission | Commission on USD 2,700 |
|---|---|---|---|
| Cement, aggregates | 6 to 10% | 3% | USD 81 |
| Steel, rebar | 5 to 9% | 3% | USD 81 |
| Blocks, bricks | 10 to 15% | 4% | USD 108 |
| Plumbing, electrical | 18 to 25% | 6% | USD 162 |
| Tiles, sanitary ware | 20 to 30% | 7% | USD 189 |
| Hardware, tools | 25 to 35% | 8% | USD 216 |
A weighted average commission of 4.5 to 5% is a reasonable year-one target. Add a premium supplier subscription of USD 400 to 800 per month for featured placement and analytics, which stabilises revenue.
Secured net-30 payment
Contractors rarely pay cash: they wait for progress payments from their own clients. The platform must pay the supplier within 48 to 72 hours and collect from the buyer at 30 days. Three setups exist: a factoring partner taking the risk for 1.2 to 2.5% of the amount, an in-house credit line backed by trade credit insurance, or simple escrow where the supplier waits for payment. The first option is the safest at launch, with per-buyer limits of USD 15,000 to 80,000 depending on track record and revenue.

Omar, an entrepreneur in Dubai, launches the platform with a USD 110,000 budget. By month six, 150 contractors order once a month with an average basket of USD 2,700, giving USD 405,000 of volume. At a 4.5% average commission, revenue reaches USD 18,225 per month. He deducts USD 6,075 in factoring costs (1.5% of volume) and USD 5,000 in running costs: USD 7,150 of monthly margin remains. At that pace the investment is recovered in about 15 months, and every additional 50 active buyers adds roughly USD 4,000 of margin.
FAQ
How many suppliers are needed at launch?
Aim for 40 to 60 active suppliers covering Dubai, Sharjah and Ajman before opening to buyers, then 150 within 12 months. Below 3 responses per quote request, buyers go back to the phone.
Which payment method should come first in the UAE?
Bank transfer and deferred payment dominate B2B, while cards serve small baskets under USD 1,500. Card fees run around 2 to 2.9% per transaction.
Should the platform handle delivery itself?
Not at first: suppliers deliver with their own trucks, the platform manages slots and proof of delivery. Own logistics only makes sense above 500 orders per month.
How much does maintenance cost?
Count USD 3,000 to 6,000 per month for technical operations and support, roughly 15 to 20% of the build cost per year.
Can we start with a cheaper MVP?
Yes, an MVP limited to catalogue, quotes and bank transfer payment costs USD 38,000 to 55,000 excl. VAT in 3 to 4 months. Net-30 payment and the mobile app come in a second phase.
