06 / Chain stage
What is customer acceptance?
The point at which the customer has tested delivered capacity against the contract and formally signed it off.
(In simple terms: the customer has checked it works and agreed to take it.)
Why AI needs it
Acceptance is the moment a construction project becomes a delivered product. Until it happens, capacity that is built, energised and full of equipment is still the operator's problem. It is the single most under-reported milestone in this sector, and the one that most reliably separates a project that is working from one that merely looks finished.
How it works
- The operator declares a tranche of capacity ready for handover.
- The customer runs acceptance testing against the criteria written into the contract.
- Defects are remedied and re-tested until the criteria are met.
- The customer issues formal acceptance for that tranche.
Inputs and outputs
- Made of
- Contractual acceptance criteria, test results and a signature.
- Takes in
- Commissioned capacity and a contract that defines "working".
- Produces
- Formally accepted capacity, and usually the start of the revenue clock.
Where it gets stuck
Acceptance criteria are commercially sensitive and rarely published, so the gap between "energised" and "accepted" is often invisible from outside. T2C records acceptance only where a company has disclosed it.
A general statement about the technology. It is not a claim about any named project — where T2C can evidence a specific delay, it appears in the intelligence ledger with its source.
Where it sits in the chain
Who sells to whom. The customer signs off; the operator has delivered.
T2C tracks the delivery end of this chain. An upstream stage is shown as having happened — capacity cannot be billing unless the parts were made — and simultaneously as untracked, because no supplier, order or shipment record sits behind it.

T2C holds no sourced supplier record for this component yet.
