The verdict in three sentences
Custom B2B wholesale and distribution software in Toronto costs between EUR 55,000 and 140,000 over 4 to 8 months. Its central challenge is customer-specific pricing: rate grids, volume discounts, negotiated terms, often unmanageable in a standard tool. Add a B2B order portal and you kill double entry while cutting the order cycle by 30 to 40%.
Wholesale software modules
Wholesale lives on customer relationships and margin. Here are the bricks we price for a Toronto quote.
| Module | What it does | Build range 2026 |
|---|---|---|
| Catalog & items | Families, variants, units | EUR 9,000-18,000 |
| Customer pricing | Grids, discounts, terms | EUR 12,000-28,000 |
| Orders & quotes | Entry, approval, backorders | EUR 12,000-26,000 |
| Stock & replenishment | Multi-warehouse, reservations, thresholds | EUR 10,000-22,000 |
| B2B order portal | Customer account, history, cart | EUR 12,000-28,000 |
| Margin & KPI reporting | Margin per customer/item | EUR 8,000-18,000 |
The B2B order portal: the real lever
When your customers order online themselves, your reps focus on high-value selling. Here is the quantified impact.
| Indicator | Without portal | With portal (estimate) |
|---|---|---|
| Order cycle | 2-3 days | < 1 day |
| Entry errors | 3-6% | < 1% |
| Processing cost/order | EUR 8-15 | EUR 2-4 |
| Orders outside hours | 0% | 25-40% |
| Reorder rate | base 100 | 110-125 |
Integrations and recurring cost
Wholesale software must talk to accounting and sometimes an existing ERP. These integrations are part of the budget.
| Item | Detail 2026 | Ballpark |
|---|---|---|
| Accounting integration | Invoices, payments, entries | EUR 8,000-18,000 |
| ERP integration | Items, stock, orders | EUR 10,000-24,000 |
| Carrier gateway | Labels, tracking | EUR 5,000-12,000 |
| Supplier catalog import | Files, rates | EUR 4,000-10,000 |
| Annual maintenance | 12-18% of build | recurring |
Mini case study
Laurent runs a B2B supplies wholesaler in Toronto: 1,800 orders/month handled manually, processing cost EUR 11 each = EUR 19,800/month. Software at EUR 90,000 with a B2B portal shifts 35% of orders to self-service at EUR 3 each. On 630 automated orders, he saves 630 x EUR 8 = EUR 5,040/month, i.e. EUR 60,480/yr, before counting fewer errors and 24/7 availability. Payback in about 18 to 20 months.

FAQ
Why not buy an off-the-shelf ERP?
A generalist ERP handles complex wholesale rate grids poorly without costly development. Custom fits your exact customer terms and margin logic.
Does the B2B portal replace my reps?
No, it frees them. Reorder orders go self-service; your reps focus on winning accounts, upselling and negotiation.
How do you handle customer-negotiated pricing?
With a rule-based pricing engine: base price, volume discounts, contract terms and promotions combine automatically at the right priority level.
Can we connect our accounting software?
Yes. Invoices, credit notes and payments sync; budget EUR 8,000 to 18,000 for a reliable integration that eliminates double accounting entry.
How long to production?
From 4 to 8 months. We often ship catalog, pricing and orders first, then the B2B portal and margin reporting in batches.
