The verdict in three sentences
Shopify Plus B2B wins when the catalogue is large but pricing policy stays simple: live in 3 to 4 months with CAD 30,000 to 75,000 in integration. A custom platform becomes cheaper over 5 years once negotiated pricing stacks up (family discounts, dated contract prices, terms per warehouse) and the ERP must drive prices and stock in real time. For a Toronto distributor with 8,000 SKUs, the 5-year total cost gap can swing by CAD 150,000 either way, so the decision rests on your commercial rules more than on the sticker price.
Upfront and annual cost of each option
Distributors often compare a monthly subscription with a build quote, which distorts the picture. Line items must be aligned over the same period. Figures below are 2026 market ranges in the Greater Toronto Area, before HST.
| Line item | Shopify Plus B2B | Custom platform |
|---|---|---|
| Licence or subscription | From USD 2,300 per month, about CAD 38,000 per year | No licence, hosting CAD 600 to 1,500 per month |
| Initial setup | CAD 30,000 to 75,000 integration | CAD 75,000 to 180,000 build |
| B2B apps and connectors | CAD 750 to 2,200 per month (pricing, quotes, ERP) | Included in the build |
| ERP connector (NetSuite, Dynamics 365, Acumatica) | Middleware CAD 450 to 1,200 per month | Built once, CAD 12,000 to 30,000 |
| Maintenance and changes | CAD 9,000 to 18,000 per year | CAD 18,000 to 30,000 per year |
| Time to launch | 3 to 4 months | 5 to 8 months |
Shopify Plus brings worry-free hosting, a proven checkout and a large app ecosystem. Custom brings code ownership, no volume-based fees and business logic that follows your terms of sale exactly.
Five-year total cost: the table that decides
Reference scenario: 8,000 SKUs, 1,500 trade customers, 6 discount tiers, NetSuite ERP. Amounts are cumulative estimates before tax.
| 5-year line item | Shopify Plus B2B | Custom |
|---|---|---|
| Setup | CAD 60,000 | CAD 140,000 |
| Subscription or hosting | CAD 190,000 | CAD 54,000 |
| Apps and middleware | CAD 135,000 | CAD 0 |
| Maintenance and changes | CAD 67,000 | CAD 120,000 |
| Custom pricing work | CAD 37,000 | Included |
| 5-year total | CAD 489,000 | CAD 314,000 |
The roughly CAD 175,000 gap in favour of custom only exists if your pricing logic requires apps and bespoke work. With a simple grid (one catalogue per customer segment, volume tiers), Shopify Plus falls towards CAD 340,000 and leads during the first two years thanks to the shorter launch.
Where Shopify Plus struggles with complex negotiated pricing
Shopify Plus native B2B features cover company accounts, catalogues per company or location, volume pricing and net 30 or net 60 terms. They get tight when a distributor stacks three layers: family discounts by customer band, dated contract prices, and different free-freight thresholds per warehouse. You then need a third-party app or pricing computed in the ERP, with a monthly cost and a risk of mismatch between displayed and invoiced price.
Custom, in turn, demands project discipline: written specs, user acceptance testing with sales reps and a partner able to maintain the platform for 5 years. Our custom web applications page describes this approach, and the B2B reseller ordering portal article details what trade customers expect.

Daniel, CEO of a foodservice supplies distributor in Mississauga, manages 8,000 SKUs and 1,500 customers. His reps apply 6 discount tiers and 2,400 contract prices. On Shopify Plus he would need a pricing app at CAD 1,350 per month and ERP middleware at CAD 900 per month: CAD 2,250 × 60 months = CAD 135,000 over 5 years, on top of the subscription. Custom costs CAD 140,000 upfront but launches 3 months later. His online sales target is CAD 90,000 per month at 22% gross margin, or CAD 19,800 per month: a 3-month delay means CAD 59,400 in lost margin. Bottom line: custom still wins by about CAD 115,600 over 5 years (175,000 minus 59,400), and Daniel owns his pricing logic.
FAQ
How much does Shopify Plus cost for a B2B distributor in 2026?
The subscription starts at USD 2,300 per month, about CAD 38,000 per year, plus CAD 30,000 to 75,000 in integration. B2B apps and connectors often add CAD 750 to 2,200 per month.
What budget for a custom B2B platform in Toronto?
The market range is CAD 75,000 to 180,000 depending on pricing rules and ERP integration depth. Budget CAD 18,000 to 30,000 per year for maintenance and changes.
Does Shopify Plus handle customer-specific pricing?
Yes, through catalogues per company or location, with volume tiers and payment terms. Cascading discounts and dated contract prices across thousands of SKUs usually need an app or ERP-side pricing.
When does custom become cheaper?
In our simulations, beyond 3 layers of pricing rules and 1,000 active customers, custom pulls ahead between year 3 and year 4. Below that, Shopify Plus stays cheaper over 5 years.
Can we move from Shopify Plus to custom later?
Yes, customer, order and product data can be exported, but migration often costs CAD 22,000 to 45,000. It is better to decide after a 1 to 2 week pricing-rules mapping workshop.
