The verdict in three sentences
When 120 subcontractors send order acknowledgements, new dates and quality certificates by email, buyers spend their days copying data into spreadsheets instead of negotiating. A custom supplier extranet centralises orders, confirmations, late-delivery alerts and documents, for a Kolonell quote of 6,100 to 10,670 EUR excl. tax (medium application, 4 to 7 M FCFA on our 11/10/2026 grid). The price depends on three decisions to make first: the ERP exchange method, the level of supplier permissions and the number of document flows.
Flows to digitise first
In a Greater Toronto Area manufacturer, in automotive parts or precision machining, the subcontractor base mixes machine shops, surface treaters, carriers and raw material suppliers. Every poorly tracked flow ends up as a production delay.
| Flow | Typical current situation | With the extranet |
|---|---|---|
| Purchase orders | PDF sent by email | Order published, supplier notified |
| Order acknowledgement | Email reply or call, often late | Confirm button with committed date |
| Lead time change | Isolated email, rarely tracked | New date entered, history kept |
| Late alert | Noticed at receipt | Alert at D-5 and D-1 if unconfirmed |
| Quality and material certificates | Scattered attachments | Upload per batch, validity check |
| Compliance documents | Insurance, WSIB clearance chased by hand | Expiry tracking, automatic reminders |
| Supplier rating | Yearly spreadsheet | Service level computed continuously |
Tracking WSIB clearance certificates and insurance expiry for every contractor often justifies the project on its own.

Supplier permissions: what moves the quote
A subcontractor must only see its own orders, sometimes only those of one plant. Permission granularity weighs on the budget.
| Permission level | Example | Quote impact |
|---|---|---|
| One account per supplier | Single shared login | Base |
| Multi-user per supplier | Sales, order desk, quality | +5 to 10 % |
| Rights per buying plant | Mississauga plant, Brampton plant | +10 to 15 % |
| Rights per purchasing category | Material, machining, transport | +5 to 10 % |
| 2-level internal approval | Buyer then purchasing manager | +10 to 20 % |
| Full audit log | ISO 9001 and IATF 16949 traceability | +5 to 10 % |
Mini case study
Julien, purchasing manager at a precision machining manufacturer in Toronto (Etobicoke), leads 3 buyers and 120 subcontractors. Each buyer estimates 9 hours a week chasing acknowledgements and updating the lead time spreadsheet.

Calculation: 3 x 9 hours x 45 weeks = 1,215 hours a year. At a loaded 45 EUR an hour, that is about 54,700 EUR a year. If the extranet, quoted at 9,500 EUR, halves that time, the gain is about 27,300 EUR a year: payback in 4 to 5 months, before counting avoided production delays. A hypothesis to test with a pilot on the 20 most active suppliers.
FAQ
What does a supplier extranet cost for a manufacturer?
At Kolonell, 6,100 to 10,670 EUR excl. tax for an ERP-connected application with alerts and document upload. A simple version without API sits between 3,810 and 6,100 EUR.
How long does deployment take?
Allow 10 to 14 weeks, including a 2 to 3 week pilot with 15 to 20 suppliers. Onboarding of the 120 subcontractors then happens in waves of 30.
Will small subcontractors adopt it?
Adoption relies on a very simple mobile interface and a contractual commitment in your purchasing terms. Field experience shows 70 to 90 % adoption at 6 months once buyers stop accepting email confirmations.
Can the extranet connect to our ERP?
Yes, through API, scheduled file exchange or EDI depending on your ERP. A 2 to 3 day audit fixes the scenario and its cost before the final quote.
Where is the data hosted?
In Canada or Europe, on infrastructure aligned with PIPEDA and GDPR, with daily backups. Drawings and quality certificates are only visible to authorised suppliers.
