The verdict in three sentences
A wholesale B2B commerce platform in Singapore costs 35,000 to 110,000 USD in 2026, depending on catalogue depth, negotiated pricing per customer and ERP integration. The realistic timeline is 3 to 6 months, with annual maintenance around 10 % of build cost. The most measurable gain: average order value up +18 % thanks to quick order and multi-user accounts.
The wholesale requirements
Digitising B2B orders requires a precise foundation: catalogue with selling units, per-customer pricing grids, minimum order quantities, quick order by SKU and an ERP connection for stock and prices. Here are the 2026 line items in Singapore.
| Line item | 2026 range (USD) | Note |
|---|---|---|
| Scoping + B2B UX | 3,000 - 8,000 | Accounts, roles, pro journey |
| Catalogue + spec sheets | 4,000 - 12,000 | Units, cases, minimums |
| Negotiated pricing | 3,500 - 10,000 | Per-customer grids, contracts |
| Quick order | 2,500 - 7,000 | Order by SKU, lists |
| ERP integration | 6,000 - 20,000 | Stock, prices, orders real time |
| Payment + credit terms | 2,500 - 7,000 | Card, transfer, terms |
| UAT + training | 3,000 - 9,000 | Testing, go-live |
A distributor with 1,500 SKUs and a per-customer grid usually lands around 40,000 to 60,000 USD. A simple catalogue with no ERP stays under 30,000 USD.
ERP integration, the heart of the project
In wholesale, the ERP is the source of truth for prices and stock. Integration quality determines platform reliability. Here are the three levels and their impact.
| Integration level | 2026 cost (USD) | What it brings | Risk if absent |
|---|---|---|---|
| File export/import | 6,000 - 9,000 | Daily sync | Stock/price drift |
| Partial real-time API | 10,000 - 15,000 | Live stock and prices | Re-keyed orders |
| Full real-time API | 15,000 - 20,000 | Orders + invoices sync | Higher upfront cost |
Full real-time sync is pricier but avoids stockouts and price errors, which cost in customer disputes and admin time. For an active distributor, it pays back quickly.
Mini case study
Karim, manager of an electrical-equipment distributor in Singapore, serves 600 pro customers with a 4,200 USD average order. He invests 60,000 USD in a B2B platform with negotiated pricing and real-time ERP integration.
Over 12 months, average order rises to 4,956 USD (+18 %) and 40 % of orders shift to self-service. On 14,000 orders/year, the order-value gain represents roughly 10,584,000 USD in additional revenue, and the admin team saves 1.5 FTE on data entry. The annual maintenance of 6,000 USD (10 %) is marginal. The investment pays back in under 2 months on additional margin.
