The verdict in three sentences
A B2B matchmaking platform succeeds first on liquidity: without 200 verified suppliers at launch, buyers do not come back, whatever the quality of the code. Sharetribe (CAD 400 to 700 a month) lets you test the market in 4 to 6 weeks if your flow looks like a standard marketplace. A custom build (CAD 70,000 to 130,000, 4 months) becomes necessary as soon as you handle RFQs, multi-line quotes, business registration and insurance checks, and a 5 to 8% commission on orders worth several thousand dollars.
What an industrial buyer really expects
A buyer at an aerospace supplier in Mississauga is not looking for a catalogue: they post a need (machining 500 aluminium parts, surface treatment, tight tolerances) and want 3 to 5 comparable quotes from qualified subcontractors. The B2B journey therefore differs from a consumer marketplace on specific points.
| Capability | Sharetribe (configured) | Custom |
|---|---|---|
| Need posting and RFQ | Possible workaround, limited | Native, with spec sheet attached |
| Multi-line quotes and negotiation | No | Yes, versioned |
| Business registration, WSIB, insurance certificate checks | Manual | Automated (registry API, reminders) |
| Certifications (ISO 9001, AS9100) | Text field | Filters and expiry dates |
| Messaging with attachments and drawings | Basic | Full, per-project permissions |
| Payment and commission | Stripe Connect built in | Stripe Connect or direct invoicing |
| Upfront cost | CAD 400 to 700 a month | CAD 70,000 to 130,000 |
2026 development and operating budget
A credible custom V1 for the industrial subcontracting market in the Greater Toronto Area breaks down as follows, as a 2026 order of magnitude.
| Item | Range (CAD) |
|---|---|
| Scoping, user journeys, wireframes | 8,000 to 14,000 |
| Buyer and supplier accounts, profiles, certifications | 12,000 to 21,000 |
| RFQs, quotes, messaging | 19,000 to 37,000 |
| Registration and insurance checks, moderation back office | 9,000 to 18,000 |
| Stripe Connect payment and commission | 9,000 to 18,000 |
| SEO, supplier pages, QA | 13,000 to 22,000 |
| V1 total | 70,000 to 130,000 |
| Operations (hosting, maintenance, Stripe excluding commissions) | 1,300 to 2,600 a month |
The commercial launch budget is often underestimated: onboarding 200 suppliers takes 3 to 4 months of a business developer (about CAD 5,500 a month in Toronto), so CAD 22,000 to 30,000 loaded to plan alongside the code.
Which business model to choose
| Model | Typical 2026 revenue | Fits when |
|---|---|---|
| Commission per order | 5 to 8% of order value | Payment flows through the platform |
| Supplier subscription | CAD 69 to 279 a month | Orders paid outside the platform |
| Fee per quote request | CAD 20 to 60 per qualified lead | Low volume, high tickets |
| Hybrid (subscription + 3% commission) | Both | After 12 months of history |
In industrial subcontracting, large accounts often pay on net 45 or net 60 terms by bank transfer, outside the platform. Many platforms therefore start with a supplier subscription, then add a commission once secure payment becomes a selling point.

Daniel, founder of a subcontracting platform in Toronto, invests CAD 100,000 in the V1 and CAD 26,000 in onboarding 200 suppliers. By month 6, the platform handles 15 orders a month averaging CAD 18,000, with a 6% commission, or CAD 16,200 in monthly revenue. After CAD 2,000 of operating costs, the margin is CAD 14,200 a month. The total investment of CAD 126,000 is recovered in about 9 months at that pace, provided volume holds.
FAQ
Should we start with Sharetribe?
Yes if demand is not yet validated: 3 months at CAD 550 a month cost CAD 1,650 and prove interest. If buyers require RFQs and compared quotes from day one, go straight to custom.
How can a supplier be verified automatically?
Ontario and federal business registries can be queried via API or data providers for a few cents per lookup. Insurance and WSIB certificates are uploaded, then chased automatically 30 days before expiry.
Are there specific legal obligations?
Yes. Canada's anti-spam law (CASL) governs your email outreach, and digital platforms must report seller income to the CRA above certain thresholds. Plan 2 to 3 days of development for these exports.
How many suppliers before opening to buyers?
Aim for 200 verified suppliers covering at least 10 trades. Below 3 responses per request, buyer return rates drop under 30%.
How long for the V1?
Allow 4 months of development, including 3 weeks of scoping, running in parallel with onboarding the first suppliers.
