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
- Level 1–2 file: every request is a project — days of reconstruction, discounts conceded under deadline pressure.
- Level 3 file: requests are answerable — but the file decays without maintenance and quietly slides back.
- 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.
