What it does

Four records. One defensible trail.

Built around how a practice actually reviews its own position: decisions, evidence, change and independent sign-off.

◎

People & rationale

Retain customer-owned relevance decisions, roles, review history and source versions.

▤

Owned evidence

Connect conditions to accountable owners, necessary documents and your internal review dates. Review dates are tracked and highlighted in the register and on your overview; email alerts are not available yet.

✓

Internal assurance

Prepare an independent review and archive the evidence relied on at sign-off.

↻

Change events

Role and service changes open review tasks assigned to an owner with a due date.

§

Source library

Keep HMRC and legislation references as versioned sources, with a content hash.

≡

Audit history

Every change is recorded with who made it and when, and you can download the history as CSV or export your whole register for your own files.

Internal assurance

An independent review, on the record

Readiness is your own governance workflow. Sign-off is bound to a frozen snapshot, so what was reviewed is what was signed.

1

Draft

Author assembles the cycle and period.

2

Snapshot

Records and evidence are frozen and hashed.

3

Independent review

A different member reviews the snapshot.

4

Sign-off

Requires two-factor and a recent password check.

5

Archive

Export the evidence pack for your files.
