The verdict in three sentences
In 2026, in Canada, custom inventory software for multi-warehouse stock runs CAD 60,000-150,000 (EUR 40,000-101,000) over 12 to 20 weeks, with barcode scanning and ERP sync. A vertical WMS SaaS starts faster and cheaper but charges per user and per site, and bends poorly to atypical flows. Custom pays back through two measurable levers: -30 % stockouts and inventory-count time cut by two-thirds.
WMS SaaS or custom software: the 2026 numbers
A vertical SaaS is a subscription that never amortises; custom software is an asset that fits your warehouse flows.
| Criterion | Vertical WMS SaaS | Custom software |
|---|---|---|
| Entry cost | 0 to 10,000 CAD (setup) | 60,000 to 150,000 CAD |
| Recurring cost (25 users) | ~1,500 to 4,000 CAD/month | maintenance 15-20% of build/year |
| Time to go live | 4 to 10 weeks | 12 to 20 weeks |
| Barcode / mobile scanning | Standard | Bespoke (Zebra, Android) |
| ERP sync | Limited connectors | Dedicated API |
| Atypical flows (kitting, lots) | Often out of scope | Modelled |
| Code ownership | No | Yes |
What a 60,000-150,000 CAD build covers
Scope drives price. A 2026 order-of-magnitude breakdown for a multi-warehouse logistics SME.
| Module | Range CAD | Indicative time |
|---|---|---|
| Product catalogue + variants + locations | 10,000 - 22,000 | 3-4 weeks |
| Mobile barcode scanning (receiving/picking) | 14,000 - 32,000 | 3-5 weeks |
| Multi-warehouse + inter-site transfers | 12,000 - 28,000 | 3-4 weeks |
| ERP sync (accounting, purchasing) | 10,000 - 26,000 | 2-4 weeks |
| Dashboards + stock-threshold alerts | 8,000 - 20,000 | 2-3 weeks |
| Canada hosting, acceptance testing, training | 6,000 - 12,000 | ongoing |
Annual maintenance runs 15 to 20 % of the build: on 95,000 CAD, budget 14,250 to 19,000 CAD/year. Compare that to 18,000-48,000 CAD/year in WMS subscriptions for 25 users, often excluding connector costs.

Mini case study
Karim, operations director of a spare-parts distributor in Toronto (3 warehouses, 25,000 SKUs), runs a 6 % stockout rate that drives B2B customers away. He invests CAD 98,000 in custom software with barcode scanning and ERP sync, plus 16,000 CAD/year maintenance. Cutting stockouts from 6 % to 4.2 % (-30 %) on 8 M CAD in revenue recovers roughly 1.8 % of lost sales, i.e. 144,000 CAD/year. Meanwhile the annual inventory count drops from 240 to 80 hours: 160 hours × 35 CAD/h = 5,600 CAD saved. The build pays for itself in under 9 months.
FAQ
Isn't a WMS SaaS enough? For a standard single-warehouse flow, often yes. Custom makes sense the moment you have multi-site, kitting, lots/expiry dates or deep ERP integration that the SaaS charges heavily for or doesn't offer.
Is barcode scanning complicated? No. An Android app on Zebra terminals or ruggedised phones, connected in real time, takes 3 to 5 weeks to build. It removes double entry and pushes stock accuracy above 99 %.
Realistic timeline? Budget 12 to 20 weeks for a first scope in production, rolling out warehouse by warehouse. A pilot on one site limits risk.
How does ERP sync work? Via a dedicated API to your ERP (SAP Business One, Dynamics, NetSuite) for items, purchasing and stock entries. Flows are tested in acceptance before go-live.
Can we start small? Yes. Many begin with catalogue + scanning on one warehouse at 30,000-45,000 CAD, measure stock accuracy, then extend to multi-site. That's the approach we recommend.
