The verdict in three sentences
For a building materials distributor serving 1,500 contractors and tradespeople in Riyadh, a B2B ordering platform first exists to absorb the repetitive quotes that overload the sales desk, not to replace the trade counter. The features that create value are specific: customer and volume pricing, one-click quote to order, site delivery slots, payment by mada card, SADAD or bank transfer, and visible credit limits. As a 2026 order of magnitude, the project costs 250,000 to 700,000 SAR with a Saudi integrator and takes 4 to 5 months.
The features that matter in building materials trade
Building materials trade has constraints consumer e-commerce ignores: thousands of SKUs sold by weight, pallet or cubic metre, prices negotiated per project, deliveries by crane truck with restricted access, and customers paying at 60 or 90 days. A standard online shop handles none of this.
| Feature | Why it matters | Complexity | Share of budget |
|---|---|---|---|
| Multi-unit catalogue (bag, pallet, tonne, m³) | Cement, rebar, blocks sold differently | Medium | 10 % |
| Customer and volume price lists | Discounts negotiated per project | High | 15 % |
| Online quote converting to order | 60 % of requests start as a quote | Medium | 15 % |
| Site delivery slots | Crane truck, hours, access | High | 15 % |
| mada, SADAD, transfer, credit limit | Cash or 60 to 90 day credit | Medium | 10 % |
| ERP integration (SAP B1, Odoo, Oracle) | Real-time stock and invoicing | High | 20 % |
| Customer area: invoices, delivery notes | Fewer support calls | Low | 5 % |
| Mobile app for site managers | Ordering from the site | Medium | 10 % |
ERP integration is the riskiest item. If online stock is not synced at least every 15 minutes, sales reps go back to the phone and the platform is abandoned within three months.
What a B2B platform costs in Riyadh in 2026
| Option | Upfront cost (2026 order of magnitude) | Annual cost | Timeline | Fits when |
|---|---|---|---|---|
| B2B module of a standard e-commerce CMS | 70,000 to 160,000 SAR | Licences 15,000 to 40,000 SAR | 2 to 3 months | Under 500 SKUs, simple pricing |
| Saudi integrator, custom platform | 250,000 to 700,000 SAR | Maintenance 15 to 20 % of project | 4 to 5 months | 1,000+ customers, ERP to connect |
| International B2B suite (SaaS) | 300,000 to 900,000 SAR over 3 years | High subscription | 4 to 6 months | Multi-country group |
| Kolonell, complex application | 7,000,000 to 15,000,000 FCFA (10,670 to 22,870 EUR, about 44,000 to 94,000 SAR) | Maintenance 75,000 to 120,000 FCFA/month | 16 to 20 weeks | Defined scope, documented ERP |
The Kolonell price matches our "complex application" band. The low end covers catalogue, customer pricing, quotes, ordering and payment; the high end adds two-way ERP integration, delivery planning and the site mobile app.
Mini case study
Faisal, CEO of a building materials distributor in Riyadh (illustrative scenario), serves 1,500 customers with 8 inside sales reps who each handle 35 quotes a day. If the platform absorbs 40 % of simple quotes, each rep gains about 2.5 hours a day, 20 hours daily for the team, redirected to large projects. On revenue, he targets 3 % more orders thanks to after-hours ordering: on 120,000,000 SAR in annual sales and 12 % gross margin, that is 432,000 SAR of margin. A 450,000 SAR project pays back in about 12 months, before counting fewer delivery errors.

Is card payment suited to large B2B orders?
mada and card payment suit tradespeople and small firms, with a fee of roughly 1 to 2.5 % depending on the acquirer. For large amounts, the platform offers bank transfer, SADAD and payment on approved credit terms.
Can prices differ by customer?
Yes, that is the core of B2B: each logged-in customer sees their price list, volume discounts and terms. Allow 3 to 4 weeks to import and test existing price lists.
How are site delivery slots managed?
The customer picks a slot among those available based on fleet capacity and truck type. Access constraints (crane truck, municipal hours) are entered once per site.
Do invoices need a specific format in Saudi Arabia?
Yes, ZATCA e-invoicing (Fatoora) applies, with QR code and integration with the authority in phase 2. The platform pulls compliant invoices from the ERP rather than generating duplicates.
Should everything launch at once?
No, a two-step launch works better: quotes and orders for 100 pilot customers in 3 months, then rollout to all and the mobile app in month five.
