Between a supplier’s first phone call and their first purchase order from a mine sits a process that kills more sales than any competitor: vendor onboarding. It is slow, document-heavy and different at every mine, and suppliers who treat it as an afterthought discover it at the worst moment, when an order is ready and the system will not accept them. Here is the process from the inside, and how to move through it deliberately.
How does a supplier get approved by a mine?
Through vendor registration: submitting company, tax, safety, insurance and empowerment documentation to the mine’s vendor management system, passing verification, and being loaded as an approved vendor with a number. Only then can requests for quotation reach you and invoices get paid.
The document pack, and why each item exists
The standard requests look bureaucratic until you see them from the mine’s side. Company registration and directorships: they are screening for fronting and conflicts. Tax clearance: an invalid supplier creates tax liability for the buyer. Safety file and statistics: a contractor’s injury on site is legally the mine’s injury, so your safety record is their risk. Insurance and letters of good standing: same logic. Financial statements: they are about to depend on you, and suppliers that fail mid-contract cost more than they ever saved. Empowerment credentials: in South Africa, Mining Charter procurement targets make your scorecard part of their licence to operate, and elsewhere local-content rules do the same through different paperwork. References: cheap verification of everything above. None of it is optional, and most of it expires, which is the trap: onboarding is not a one-time event but a maintained state.
Verification, the invisible middle step
Most large mining groups no longer check documents themselves. Third-party verification services validate the pack, chase expiries and score suppliers, and the mine sees a dashboard. Practical consequences: your documents must match exactly across systems, name spellings, banking details and addresses inconsistent between forms cause silent rejections, and the verification firm is a relationship worth cultivating, because they can tell you precisely what is blocking your file. Budget weeks for this stage at best, months at worst, and never start it after the order is on the table. The wider process it gates is described in how mining procurement actually works.
From registered to actually buying
A vendor number produces nothing by itself. Registered suppliers still need demand to find them, and that happens three ways: requests for quotation routed by commodity codes, so choose your registration categories carefully and broadly. End-user pull, the engineer or foreman who wants your product and asks procurement to source it, which is why site relationships still open doors that systems cannot. And small first orders: mines test new vendors deliberately on low-risk purchases, so treat the R20,000 order as the audition it is, because payment terms, delivery discipline and paperwork accuracy on that order decide whether the R2 million one follows. Suppliers who deliver flawlessly and invoice cleanly climb vendor rankings that they are never shown.
The shortcuts that exist, and the ones that do not
Legitimate accelerators: supplier development programmes at the majors, which fast-track local and empowered businesses and sometimes fund their compliance costs. Piggybacking through established contractors as a sub-supplier while your own registration matures, as covered in the contractor landscape. And arriving pre-verified because another mine in the same group already onboarded you. What does not work: pressure through the buyer, who cannot override compliance, and anyone offering to sell you access, which is a phrase to end meetings on.
What this means for suppliers
Onboard before you need to. Pick the ten operations that matter most to your product, register and maintain your file at each, and then work demand with the paperwork already behind you. Knowing which projects and mines to pick is the intelligence half of the problem. AMIQ tracks 2,200+ African mining projects with verified owner and engineer contacts, so the registration effort lands where the spending will be.

Frequently asked questions
How long does vendor registration at a mine take?
From a few weeks to several months, depending on the mine’s verification process and the state of your documents. Expired certificates and inconsistent details are the usual causes of delay, which is why maintained files onboard fastest.
What is a vendor number?
The identifier a mine’s system assigns an approved supplier. Without it you cannot receive official requests for quotation or be paid. With it, you are visible to buyers searching your commodity categories.
Do small suppliers stand a chance with big mines?
Yes, particularly local and empowered businesses, which procurement targets actively favour in South Africa and increasingly across Africa. Supplier development programmes exist precisely to onboard them. The route in is compliance readiness plus a flawless first small order.
Can I supply a mine through another company?
Yes. Sub-supplying through an established contractor or agent is a legitimate and common entry path while your own registration matures. The trade-off is margin and the relationship belonging to someone else, so treat it as a bridge, not a destination.
