An evidence file organised once starts decaying the day it is delivered: licences expire, suppliers change, a new questionnaire arrives with different questions. Continuous Evidence Management is the retainer that keeps a file at SEMM level 4 — continuously managed — instead of letting every buyer request restart the archaeology.

This is advisory work. It is not an audit, certification, legal opinion, emissions verification or a guarantee of buyer acceptance — and every deliverable states that boundary.

What is managed, month to month

Expiry & validity control

Every dated record tracked; renewals flagged before they become gaps a buyer finds first.

Update calendar

A register of what changed in the operation and which records must follow — with owners and dates.

Request support

When a questionnaire, clause or data request arrives, the answer is assembled from the maintained structure — reviewed, scoped, on the buyer's deadline.

Periodic re-grading

The file re-graded against SEMM at agreed intervals, so improvement (or decay) is visible and assignable.

The economics of level 4

  1. Level 1–2 file: every request is a project — days of reconstruction, discounts conceded under deadline pressure.
  2. Level 3 file: requests are answerable — but the file decays without maintenance and quietly slides back.
  3. Level 4 file: requests are exports. The cost is a predictable retainer instead of unpredictable emergencies — and the buyer notices the difference in response time.

Questions we hear first

Do we need a review first?

Usually yes — the retainer maintains a structured file. The Supplier Evidence Review builds the structure; this keeps it alive.

What shapes do retainers come in?

Annual, in three cadences — from an essential rhythm for stable files to close accompaniment for chains under active buyer pressure. Scoped case by case, with a written proposal.

Can it cover several suppliers?

Yes — buyer-side programmes maintain graded files across a supplier cohort; see for European buyers.
