Approving suppliers against your own criteria

Making "approved" mean the same thing whoever decides it.

Updated on 13/08/2026

Approving a supplier is not having the paperwork: it is deciding they can work with you. The difference shows on the day two people on the same team reach different conclusions with the same documents in front of them.

What makes "approved" mean something

The three levels that usually suffice

LevelWhat it requiresWho approves
ApprovedEverything mandatory, current and meeting the minimumAutomatic on completion
Approved with conditionsSomething non-blocking is missing, or a minimum is tightA manager, leaving the note
Not approvedSomething blocking is missing, or a minimum is breachedAutomatic, and communicated

Important

The middle level is what stops approval becoming an empty stamp. Without it, people approve what does not quite comply so as not to block the work, and from then on "approved" means nothing.

The commonest design mistake

Making everything desirable mandatory. It ends with half your suppliers marked not approved over things nobody cares about, and someone bypassing the process to get work done. Mandatory means what genuinely prevents contracting.

Watch out

If approval expires — and it usually does, because insurance and certificates expire — the status has to recalculate itself. An approval reading "approved" with insurance that lapsed three months ago is worse than no approval at all.

Worth knowing

Write the criteria down even if it is four lines. The value is not in the document: it is in two different people deciding the same thing.

Can criteria differ by supplier type?

Yes, and they should: you do not ask the same of someone entering site as of someone shipping material.

What about a supplier who fails a criterion but is essential?

That is what "approved with conditions" is for: it is decided expressly and who decided is recorded.

Do we tell the supplier why they are not approved?

It helps: most fix it once they know what is missing.

A real case

The situation

Two buyers at the same company approve suppliers by different standards.

What you do

  1. Write four criteria with their minimums
  2. Add an "approved with conditions" level for exceptions

What you get

"Approved" comes to mean the same thing whoever decides, and exceptions carry a name and a reason.

The situation

Each department approves suppliers on different criteria and the same supplier passes in one and fails in another.

What you do

  1. Sets a common list and writes it down
  2. Marks what is mandatory and what is desirable
  3. Applies the same criteria to suppliers already working with you

What you get

Approval means the same across the company and stops depending on who does it.

The situation

A document nobody ever looks at is requested.

What you do

  1. Reviews what is actually used and drops the rest

What you get

The supplier delivers sooner because less is asked.

The situation

A critical supplier passes on the bare minimum.

What you do

  1. Matches the level of scrutiny to the risk

What you get

What is critical is examined more closely than what is incidental.

The situation

Approval happens once and nobody reviews three years later.

What you do

  1. Schedules the periodic review

What you get

The approval stays true.

The situation

The criteria live in one person's head.

What you do

  1. Writes them into the template

What you get

Approval outlives whoever set it up.
