The verdict in three sentences
A B2B e-commerce platform in Toronto is priced between EUR 18,000 and EUR 120,000 in 2026, depending on whether you start from a configured SaaS base or a fully custom build. The real cost sits not in the catalogue but in customer accounts, negotiated price grids, approval workflows and online quoting. Plan for 3 to 7 months of delivery and budget 15 to 20 % of the initial cost per year for maintenance and evolutions.
What sets B2B e-commerce apart from B2C
B2B is not B2C with a different tax rate. Each customer has its own price grid, payment terms, authorized credit limit and sometimes a restricted catalogue. A professional buyer wants to find their references, reorder in one click, download invoices and request a quote on large orders. These functions radically change the estimate.
| Functional block | Complexity | 2026 cost (EUR) |
|---|---|---|
| Catalogue + B2B product pages | Standard | 3,000 - 8,000 |
| Customer accounts & multi-user | Medium | 4,000 - 12,000 |
| Negotiated price grids | High | 5,000 - 15,000 |
| Online quoting & approval | High | 6,000 - 18,000 |
| Credit limits & deferred payment | Medium | 3,000 - 9,000 |
| ERP connector / real-time stock | High | 8,000 - 25,000 |
| Support portal & order tracking | Medium | 3,000 - 7,000 |
Comparing the technical solutions
Three solution families dominate the Toronto market in 2026. The choice depends on your number of references, the level of pricing customization and your existing information system.
| Solution | Entry ticket (EUR) | Annual cost | Best for |
|---|---|---|---|
| Shopify Plus B2B | 22,000 - 45,000 | 24,000 - 30,000 | Catalogues < 5,000 refs, fast launch |
| Medusa / open-source headless | 35,000 - 90,000 | license 0, hosting 6,000 | Complex pricing logic, custom |
| Custom Next.js + Supabase | 45,000 - 120,000 | hosting 4,000 - 9,000 | Deep ERP integration, differentiation |
| BigCommerce B2B Edition | 18,000 - 40,000 | 15,000 - 28,000 | Multi-channel SME, controlled budget |
SaaS shortens time-to-market but charges an annual fee that grows with revenue. Custom costs more upfront but removes the fee and makes you the owner of your code, a key point if your pricing rules fall outside standard patterns.
Mini case study
Mark, sales director at an industrial supplies distributor in Toronto, handles 140 B2B orders a month, each going through a 25-minute manual quote (email, spreadsheet, follow-up). That is roughly 58 hours a month of sales time, or at a loaded cost of EUR 35 an hour EUR 2,030 a month. By digitizing price grids and online quoting for EUR 52,000, he automates 70 % of those quotes. Monthly saving: EUR 1,420, plus a 9 % higher average order value thanks to fast reordering. The project pays back in about 24 months, not counting new customers captured outside opening hours.

Need a professional website?

What is the minimum budget for a credible B2B store?
Plan at least EUR 18,000 for a SaaS base with customer accounts and a simple price grid. Below that, you get a disguised B2C that will frustrate professional buyers on their first order.
How long to go live?
Between 3 and 7 months depending on scope. A Shopify Plus B2B base ships in 10 to 14 weeks; a custom build with an ERP connector takes 5 to 7 months including testing and data migration.
Do we need to connect the ERP at launch?
Not necessarily. Many SMEs launch with stock synced by a daily CSV export (saving EUR 8,000 to 15,000) then move to real-time once traffic is proven.
What annual maintenance should we expect?
Between 15 and 20 % of the initial budget, i.e. EUR 3,000 to 20,000 a year, covering security, evolutions, hosting and support. Underfunding this creates technical debt within 18 months.
Can deferred payment be managed online?
Yes. You combine a capped credit limit, automatic approval under a threshold and integrated dunning; the module costs EUR 3,000 to 9,000 and sharply cuts unpaid invoices versus manual tracking.
