S6 · Delivery window quoted from the agreed build plan
Feature-Complete Product Build
A complete production product, built from the agreed plan and delivered with verification, runbooks and operational handover.

Constructed handover specimen · not a client finding
The handover includes an interrupted transaction
- Trigger
- The external service accepts the request, but the connection fails before confirmation arrives.
- What you receive
- The release record links the submitted identifier, reconciliation result, recovery procedure and repeatable retry test.
- Decision supported
- The operator can establish whether the action occurred and continue safely. A successful screen alone does not satisfy this handover.
Who it is for
Organisations that need the complete product, not an indefinite development team.
- The work
- We build the running system and its verification together, including operating paths, recovery, documentation and the evidence needed to hand ownership over cleanly.
- The boundary
- Scope and price come from the compiled plan. We absorb the execution risk inside that boundary. Only a new or changed requirement is separately quoted and approved; we do not hide either kind of change by delivering less.
What you receive
Running production system, tests, verification harnesses, runbooks and handover; optional hosting.
- Duration
- Delivery window quoted from the agreed build plan
- Price (GBP)
- from £60,000
- Commercial shape
- fixed from the agreed plan or revenue share
