The verdict in three sentences
In Singapore in 2026, a SaaS commercial management system at 55 to 150 USD per user per month suffices for a single-warehouse wholesaler, but a custom multi-warehouse build (55 000 to 140 000 EUR) pays off once you handle customer-specific pricing, EDI and multiple depots. The key in distribution is seeing real margin per customer and anticipating stockouts. The software pays back on tied-up stock and saved sales, not on the license price.
What distribution software costs in 2026
Three approaches structure the Singapore market. 2026 orders of magnitude (net).
| Option | Entry cost | Recurring cost | Timeline |
|---|---|---|---|
| SaaS commercial management | 0 to 7 000 USD | 55 to 100 USD/user/month | 4 to 8 weeks |
| Verticalized distribution SaaS | 7 000 to 22 000 USD | 100 to 150 USD/user/month | 2 to 4 months |
| Custom Kolonell | 55 000 to 140 000 EUR | 12 %/year maintenance | 5 to 9 months |
| EDI module only | 12 000 to 30 000 EUR | 12 %/year maintenance | 2 to 3 months |
For 14 users (sales, order desk, purchasing), a SaaS at 110 USD costs 18 480 USD/year in licenses. Over five years, 92 400 USD excluding EDI and integrations: custom compares quickly.
Inside a custom multi-warehouse build
Development on day rate between 500 and 800 EUR in Singapore. Breakdown of a 90 000 EUR budget.
| Item | Budget share | Indicative amount |
|---|---|---|
| Scoping and pricing model | 12 % | 10 800 EUR |
| Multi-warehouse and stock | 24 % | 21 600 EUR |
| Customer pricing and discounts | 20 % | 18 000 EUR |
| EDI and supplier connections | 20 % | 18 000 EUR |
| Margin dashboard | 14 % | 12 600 EUR |
| Testing and training | 10 % | 9 000 EUR |
The per-customer margin dashboard is the differentiator: it reveals accounts where you lose money despite high revenue. The 12 %/year maintenance is roughly 10 800 EUR.
Mini case study
Daniel, owner of an industrial-supplies wholesaler in Singapore (3 warehouses, 12 M EUR revenue), suffers 25 % stockouts on A-class SKUs costing about 180 000 EUR/year in lost sales. He invests 88 000 EUR in a custom build with driven replenishment and supplier EDI. Over twelve months: -25 % stockouts (about 45 000 EUR of saved sales, net margin ~15 000 EUR) and, crucially, the discovery that 3 high-volume customers were margin-negative after discounts, fixed the next quarter for +32 000 EUR annual margin. ROI in around 22 months.

FAQ
Does a SaaS handle customer-specific pricing?
Verticalized solutions offer it, but often on a simple grid. Custom handles negotiated terms, tiers, year-end rebates and per-warehouse pricing, all common in distribution.
Is EDI essential?
Not at launch, but as soon as big customers or suppliers require it, budget 12 000-30 000 EUR. It removes double order entry and firms up lead times.
Can we see margin in real time?
Yes, that is the point of custom: margin per line, per customer and per warehouse, discounts and logistics costs included. It is often invisible in a generic SaaS.
What timeline for a multi-warehouse project?
Between 5 and 9 months in Singapore in 2026, with a pilot warehouse delivered by month 4 to validate flows before rollout.
Does it handle purchasing and stock?
Yes: replenishment suggestions based on sales and supplier lead times, stockout alerts, and stock cover per SKU and per warehouse.
