How it works

Follow one milestone on a rear extension, from the contract to the payment to the record that outlives the build. Each step plays as you reach it.

Step 1 of 6: AgreeStep 1 of 5: Agree

The contract sets milestone 3. Everyone sees the same one.

Step 2 of 6: Capture

Before the plasterboard goes up, the builder captures it live.

Step 3 of 6: CheckStep 2 of 5: Capture and check

Cemento checks the evidence: live, on site, on time, unaltered.

The builder captures it live, and Cemento checks it: on site, on time, unaltered.

Step 4 of 6: SignStep 3 of 5: Sign

The architect certifies the milestone. Their name is on it.

Step 5 of 6: PayStep 4 of 5: Pay

Proof moves the money: released the moment the architect signs.

Step 6 of 6: KeepStep 5 of 5: Keep

Every party’s fingerprint, in one record nobody can rewrite. The passport stays with the building.

2031: A kitchen refit. Where are the pipes? The first-fix photos show them. 2034: A sale. The buyer’s surveyor reads the passport. 2041: A defect claim. Who built, checked and paid is still on record.
