The verdict in three sentences
A procurement team running 220 tenders a year by email and spreadsheet can neither compare bids cleanly nor prove, if audited, that supplier choices were justified. An e-sourcing platform with online bid submission, weighted scoring grids and a full audit trail structures the process and targets 3 to 5% savings on the tendered scope. Against e-sourcing SaaS at 25,000 to 70,000 EUR a year, a Kolonell custom build sits between 2,500,000 and 15,000,000+ FCFA (3,810 to 22,870+ EUR) depending on complexity, in 4 to 6 months, with the rest priced in the quote.
What email tendering costs a mid-size company
The company designs and builds industrial equipment and spends 120 million EUR a year: materials, machining subcontracting, electronics, freight, professional services. Eight buyers run around 220 tenders, each sent to 4 to 8 suppliers. Specifications go out as attachments, questions arrive in no particular order, bids come back in incomparable formats, and the summary is rebuilt in a spreadsheet every time.
Three problems follow. Fairness: one supplier gets an answer to a question, the others do not. Comparison: without a common price schedule, a buyer spends 1 to 2 days per tender normalising bids. Traceability: anti-bribery rules expect documented third-party due diligence and controls. In the UK, the Bribery Act 2010 rewards adequate procedures; in France, Sapin II applies to companies above 500 employees and 100 million EUR of revenue. An award decision without a documented history is hard to defend.
| Step | By email | With the platform | Estimated gain (2026 order of magnitude) |
|---|---|---|---|
| Publishing specifications | Attachments, multiple versions | Single versioned pack, access per invited supplier | No version confusion |
| Clarification questions | Individual emails | Central Q&A, answers published to all | Demonstrable equal treatment |
| Bid receipt | Free formats | Mandatory price schedule, locked deadline | 1 to 2 days of normalisation avoided |
| Evaluation | Rebuilt spreadsheet | Weighted grid for price, quality, lead time, ESG | Comparison in minutes |
| Negotiation | Scattered exchanges | Logged negotiation rounds | Complete history |
| Award | Verbal or email decision | Signed, archived award report | Audit trail |
| Supplier due diligence | Separate file | Supplier record with documents and risk score | Easier controls |
E-sourcing SaaS or custom platform
Market e-sourcing suites are mature: reverse auctions, questionnaire libraries, supplier management. For a mid-size company the question is what it actually uses versus what it pays. An 8-person procurement team often uses 20 to 30% of the modules of a suite designed for large groups, and the licence comes back every year.
| Criterion | E-sourcing SaaS | Kolonell custom platform |
|---|---|---|
| Annual or upfront cost | 25,000 to 70,000 EUR a year (2026 order of magnitude) | 2,500,000 to 15,000,000+ FCFA (3,810 to 22,870+ EUR) depending on complexity, one-off |
| Recurring cost | Licence, often indexed | Maintenance 35,000, 75,000 or 120,000 FCFA a month (53, 114 or 183 EUR), hosting in the quote |
| Scoring grids | Vendor templates | Your criteria and weightings per spend category |
| ERP integration | Standard connectors, sometimes extra | Link to your ERP and supplier master data |
| Reverse auctions | Included | Possible as an add-on release, quoted |
| Rollout time | 2 to 4 months | 4 to 6 months |
| Data ownership | Export per contract | Your own database |
On the Kolonell grid, a simple platform (publication, Q&A, bid submission) sits between 2,500,000 and 4,000,000 FCFA (3,810 to 6,100 EUR). A medium one, with price schedules, weighted grids and award reports, between 4,000,000 and 7,000,000 FCFA (6,100 to 10,670 EUR). The full scope, with supplier records and risk scoring, ERP link and single sign-on for staff, is complex: 7,000,000 to 15,000,000+ FCFA (10,670 to 22,870+ EUR).
A typical plan: 4 weeks of scoping with buyers and compliance, 10 to 14 weeks of development, a pilot on 15 live tenders, then rollout by spend category.
Mini case study
David, procurement director, estimates that 35 million of the 120 million EUR of spend goes through a formal tender each year. A 3% saving on that scope is 1,050,000 EUR, and even a cautious 1% gives 350,000 EUR.

On tooling over three years: SaaS at 45,000 EUR a year costs 135,000 EUR. The custom platform at the top of the complex range costs 22,870 EUR plus 183 EUR a month of maintenance, 29,458 EUR over three years, hosting extra per the quote. The 8 buyers also recover 1.5 days per tender, about 330 days a year redirected to negotiation and supplier development.
FAQ
Does the platform cover anti-bribery compliance on its own?
It provides the audit trail and documented supplier due diligence, two expected pillars. Risk mapping and the code of conduct remain with the compliance team.
Do suppliers pay or install anything?
No, they receive an invitation and submit through a browser. It takes about 10 minutes for a regular supplier.
Can the platform connect to our ERP?
Yes, the link to supplier master data and purchase orders is part of the complex level. The exact connector is defined during scoping and quoted.
How long until the first online tender?
About 4 months for the 15-tender pilot, then 1 to 2 months of rollout. A first simple release can be live in 10 to 12 weeks.
Are the 3 to 5% savings guaranteed?
No, it is a target observed when bids become comparable and competition systematic. Actual savings depend on spend categories and the number of suppliers invited.
