Most S2P transformations are measured by the wrong things — go-live dates, modules deployed, training sessions delivered. These are implementation metrics, not adoption metrics. And the gap between the two is where value quietly disappears.
A platform can be technically perfect and behaviourally ignored. Users do not reject systems because they are difficult to understand. They reject them because they are difficult to use at the moment of need. The decision to comply or circumvent happens in seconds — at the point of purchase, not in a training room.
Maverick spend is the most visible symptom. But the real damage is subtler: incomplete data, broken approval chains, unenforceable controls, and a growing shadow economy of purchase orders raised retrospectively to legitimise decisions already made. By the time leadership notices, the behaviour is entrenched. Retraining does not fix it. Enforcement does not fix it. The root cause is always the same — too much friction at the entry point.
Catalogues and purchasing cards are not peripheral features of an S2P platform. They are the front door.
A well-configured catalogue removes the need for a user to think. The item is there, the price is right, the supplier is approved, and the transaction completes in three clicks. That is not convenience — that is compliance by design.
A properly governed P-card programme captures the transactional tail that no catalogue will ever fully cover — the low-value, high-frequency purchases that bleed through every organisation. When P-card data flows back into the platform automatically, it closes the loop without adding friction. When these two channels work well together, adoption follows naturally.
Not when usage hits 100%. That is a compliance target, not an adoption outcome. Optimum adoption is when the right transactions flow through the right channels with the right controls — without manual intervention. Four signals tell you when you are there:
The next evolution in S2P adoption is not better training or stronger policy. It is removing the decision entirely.
Intake-to-procure tools powered by agentic AI can identify what a user needs, match it to the right buying channel — catalogue, P-card, sourcing event — and route it correctly before the user has to make a single choice. The system does not wait to be used correctly. It guides the transaction to the right outcome automatically.
This is not automation in the traditional sense. It is embedded intelligence at the moment of need — which is precisely where adoption has always been won or lost. The front door just got smarter.
