When the client says you didn't deliver a feature

Chat platforms are designed for conversation, not record-keeping. A thumbs-up reaction has no attribution to a specific role. A "looks good" doesn't specify what was being approved. Channels get archived, people leave, threads get edited or deleted. When a client disputes delivery six months later, the chat history is either gone, ambiguous, or contested.

Worse, chat approvals carry no conditions. If the release shipped with a known limitation (the iOS guest checkout excluded, payment retry not yet wired up), and the client signed off without that being explicitly written down, the limitation becomes a "missing feature" the moment something goes wrong.

A defensible delivery record has four elements. Miss any one and the record is contestable.

1. Scope: what was delivered, what was excluded, what was degraded. Specific to the release, not the contract.
2. Conditions: known limitations and accepted risks, written down before sign-off.
3. Attribution: a named individual with role and timestamp. Not "the team", not a channel.
4. Immutability: once signed, the record cannot be edited. Changes create a new version with a new sign-off.

The pattern is the same whether you use a spreadsheet, a custom tool, or Dockbase: capture the four elements at the moment the release is approved, not when it's questioned.

• Define release scope in writing. List included and excluded items per platform.
• Document known limitations explicitly. "Payment retry deferred to v2.1" is a limitation.
• Name a single decision owner. They sign off, not the team.
• Capture sign-off with name, role, and UTC timestamp.
• Lock the record. No edits, only new versions.
• Send the client a copy on the day of release, not on the day of dispute.

Dockbase exists to do this in minutes per release, with structured fields and an immutable audit trail you can hand to a client, an auditor, or a lawyer.
