The verdict in three sentences
A mining services company that runs 250 tenders a year by email can neither prove its choices are fair nor compare bids properly. A custom supplier tendering platform, between 12,000,000 and 28,000,000 FCFA (about 18,300 to 42,700 EUR, or 20,000 to 46,000 USD), centralises supplier onboarding, receives sealed bids until the deadline, produces an automatic comparison and keeps a complete audit trail. Delivered in 4 to 6 months, it enables, as a 2026 order of magnitude, 5 to 8% savings on tendered amounts, far above its cost in year one. Our benchmark case is a Bamako contractor; a mining group managing procurement from Toronto will recognise the same scope, with EUR and USD equivalents.
What email really costs mining procurement
A mining subcontractor buys equipment parts, tyres, drilling consumables, fuel, transport and maintenance services for remote sites. Tenders go out by email to a supplier list kept in a spreadsheet. Bids come back in different formats, some before others, some after the deadline, and the comparison is rebuilt by hand.
| Problem | By email | With the platform | Estimated effect |
|---|---|---|---|
| Average tender duration | 18 to 25 days | 8 to 12 days | -10 days |
| Suppliers consulted per file | 2 to 3 usual ones | 4 to 6 onboarded | More competition |
| Bid confidentiality | Bids readable on arrival | Sealed until opening | Provable fairness |
| Comparison | Spreadsheet rebuilt by hand | Automatic grid: price, lead time, compliance | 2 to 4 h saved per file |
| Supplier documents (tax ID, registration, certificates) | Scattered across mailboxes | Single file with expiry dates | Tracked compliance |
| Audit trail | Rebuilt during audits | Time-stamped log of each step | Audit in a few hours |
The main gain does not come from time saved but from real competition: moving from 2 to 5 suppliers per file mechanically lowers the price obtained.
2026 modules and budget
| Scope | Modules | 2026 budget | Timeline |
|---|---|---|---|
| Core | Supplier onboarding, tender creation, online bid submission | 12,000,000 to 15,000,000 FCFA (18,300 to 22,900 EUR) | 4 months |
| Standard | Core + sealed bids, formal opening, automatic comparison | 15,000,000 to 19,000,000 FCFA (22,900 to 29,000 EUR) | 4 to 5 months |
| Compliance | Standard + supplier document management, expiry alerts, audit trail | 19,000,000 to 23,000,000 FCFA (29,000 to 35,100 EUR) | 5 months |
| Integrated | Compliance + ERP link (purchase requests, purchase orders), supplier rating | 23,000,000 to 28,000,000 FCFA (35,100 to 42,700 EUR) | 5 to 6 months |
| Hosting | Cloud server with backups, based on volume | On quote | Monthly |
These amounts are 2026 estimates for 250 to 500 tenders a year and a few hundred onboarded suppliers. The supplier portal runs in a plain browser, including on a mobile connection, which matters for small regional suppliers.
How a tender runs on the platform
| Step | Actor | Typical duration |
|---|---|---|
| Need raised from the mine site | Requester | 1 day |
| Approval and choice of onboarded suppliers | Buyer | 1 day |
| Publication and Q&A | Suppliers | 4 to 7 days |
| Sealed bid submission | Suppliers | Until the deadline |
| Opening and automatic comparison | Procurement committee | 1 day |
| Award and notification | Buyer | 1 day |
Each step leaves a time-stamped trace: who opened the bid, when, which questions were asked and to whom the answers were sent. That is exactly what mining clients and auditors ask for during compliance reviews.

Amadou, procurement director of a mining services company in Bamako, runs 250 tenders a year for a tendered volume of 4 billion FCFA (about 6.1 million EUR). He chooses the Compliance scope at 21,000,000 FCFA (about 32,000 EUR). By moving from 2.5 to 5 suppliers per file, he targets 5% savings, or 200 million FCFA (about 305,000 EUR) a year. His team of 4 buyers also saves about 3 hours per file, i.e. 750 hours a year. Even with a cautious 2% savings assumption, the gain reaches 80 million FCFA (about 122,000 EUR), and the platform pays for itself in just over 3 months.
FAQ
Do suppliers pay to respond?
No, the portal is free for suppliers, who create an account and upload their documents once. Charging them would reduce competition and therefore the targeted 5 to 8% savings.
How do you guarantee a bid is not viewed before the deadline?
Bids are encrypted on submission and only open at the set time, with at least two committee members present. The platform records the exact time of each submission and rejects late ones.
Does the platform handle urgent purchases?
Yes, a fast-track procedure allows a 24 to 48 hour tender with a mandatory justification. It stays traced, which keeps urgency from becoming the rule.
Can suppliers be rated after delivery?
Yes, in the Integrated scope, between 23,000,000 and 28,000,000 FCFA (35,100 to 42,700 EUR), each order receives a lead time, quality and compliance score. These scores then weight the comparison in later tenders.
How long does it take to onboard existing suppliers?
Allow 3 to 4 weeks to import the existing base and invite suppliers to complete their file. A call campaign to the top 50 suppliers speeds up adoption considerably.
Let's scope your project. Share your number of tenders per year, your spend categories and your ERP: we will price a scope between 12 and 28 million FCFA (18,300 to 42,700 EUR) with a 4 to 6 month plan. Detailed quote within 48 h. WhatsApp +221 77 596 93 33.
