## 1. What Crownix® Sentinel is — one paragraph

**Crownix® Sentinel is the compliance operations layer for UK businesses.** It is a continuous, human-run service — augmented by document intelligence systems — that sits operationally between a company's accountant and its solicitor. Sentinel tracks every statutory, regulatory, and contractual deadline; ingests and version-controls every relevant document (contracts, policies, certificates, filings, insurances, licences); reads and triages new regulation; coordinates and chases filings so they reach the accountant or solicitor in time; and produces a monthly position review and quarterly risk report for the directors. The accountant still files. The solicitor still advises. Sentinel makes sure neither of them ever discovers something too late.

## 2. What Crownix® Sentinel is **not**

- **Not an accountant.** Sentinel does not prepare or file tax returns, statutory accounts, or VAT returns. The client's accountant does. Sentinel makes sure the accountant has the documents, deadlines, and signed authorisations they need, on time.
- **Not a law firm.** Sentinel does not give legal advice, draft contracts, or represent clients. The client's solicitor does. Sentinel makes sure contracts the solicitor produces are stored, versioned, and surfaced when they near expiry, breach, or renewal.
- **Not software.** There is no application the client has to log into, learn, or maintain. People do the work. The dashboard is a window into that work, not a tool the client operates.
- **Not a one-off audit or consultancy project.** Sentinel is a continuous engagement. It does not run sprints, ship deliverables, or close out. It runs permanently while the client is engaged.

## 4. The problem Sentinel solves

Most UK businesses run their compliance through two well-defined professional relationships — an accountant and a solicitor — plus a quietly accumulating pile of obligations that fall between them: Companies House confirmation statements, ICO data protection fees, Employer's Liability certificate renewals, VAT MTD penalty points, sector regulator notices, contract expiries, insurance renewals, certificate currency, new regulation that lands in a government PDF and is never read.

Each of these has a small probability of going wrong in a given month. Across a year, on a normal business, the cumulative probability of at least one going wrong is high. The cost is asymmetric: small annual fee to monitor, large unpredictable penalty if missed.

Specific examples Sentinel's clients have cited:

| Gap | Typical consequence |
|---|---|
| Confirmation Statement missed at Companies House | £150 penalty + strike-off risk |
| ICO data protection fee lapses unnoticed | Up to £4,350 fine |
| Employer's Liability certificate expires mid-year | Up to £2,500 / day HSE fine |
| VAT MTD penalty points accumulate quietly | £200 per breach over threshold |
| New regulation lands and goes unread for months | Discovered at audit, not at publication |

The accountant doesn't catch these because they are not accounting items. The solicitor doesn't catch them because no one has instructed them to. Sentinel exists to catch them — continuously, by default, as the standing operational layer.

## 5. What Sentinel does — the four pillars

### 5.1 Compliance Monitoring
Continuous tracking of deadlines, regulatory changes, and document expiry across HMRC, Companies House, ICO, HSE, and the relevant sector regulators (CQC, FCA, GLAA, SIA, FSA, etc. depending on the client's profile). New guidance is read on the day it publishes, the client's exposure is assessed, and the result is surfaced as either a no-impact note or a prioritised action.

### 5.2 Document Intelligence
Every contract, policy, filing, certificate, insurance document, and licence the business holds is ingested, categorised, dated, version-controlled, and placed in a structured Document Vault. Expiries and renewal windows are tracked automatically. When a document approaches expiry the system raises it; when a document is superseded the prior version is preserved with provenance.

### 5.3 Deadline & Filings Operations
Sentinel prepares, coordinates, and chases. The accountant still signs. The solicitor still advises. But the work of getting the right pack to the right professional in time — with all supporting documents, board approvals, and signatures lined up — is run by Sentinel. Nothing slips between the two professional relationships.

### 5.4 Monthly Position Review
A standing 45-minute call each month between the client (typically a director or finance lead) and the assigned operator. The client receives a written summary of the month's filings, exposures, and pending decisions; a prioritised action list; and a direct line to the operator for anything that comes up between calls. A formal **quarterly risk report** is produced for the board, the insurer, the lender, or anyone else who needs the compliance position formatted for review.

## 6. How an engagement works — the five stages

### Stage 01 — Onboarding & Audit (Week 1)
Discovery call, document collection, baseline audit across the client's statutory, regulatory, and operational obligations. The existing accountant and solicitor are noted as part of the working perimeter. **Deliverable: Baseline Compliance Audit.**

### Stage 02 — Ingestion & Indexing (Ongoing)
Contracts, policies, filings, certificates, insurance, licences. Each document is ingested, tagged, dated, and made available in the client's Document Vault. Expiries and renewal windows are tracked automatically. **Deliverable: structured Document Vault.**

### Stage 03 — Continuous Monitoring (Daily)
HMRC, Companies House, ICO, HSE, sector regulators. New guidance is read, exposure is assessed, and the result is surfaced as either a no-impact note or a prioritised action. **Deliverable: prioritised alerts.**

### Stage 04 — Monthly Position Review (Monthly)
A 45-minute call walking the client through the month's filings, exposures, and pending decisions. **Deliverable: written summary + prioritised action list.**

### Stage 05 — Quarterly Risk Report (Quarterly)
A formal, structured quarterly document the client can present to a board, an insurer, a lender, or a counterparty without translation. Compliance position, risk movement, outstanding exposures, action history. **Deliverable: Quarterly Risk Report.**

## 7. Sectors served

Sentinel is **sector-agnostic** — the machinery is the same; the calendar, the regulators, and the documents change. Eight sectors are explicitly profiled:

| Ref | Sector | Profile | Pressure points |
|---|---|---|---|
| SEC-01 | Construction & Trades | Project-based revenue, subcontractor heavy, exposed across CIS, HSE, and insurance renewals. | CIS monthly returns; CDM 2015 documentation; Public & Employer's Liability |
| SEC-02 | Recruitment & Staffing | Worker-status risk, payroll velocity, licensing exposure across multiple end-clients. | IR35 status determinations; GLAA / SIA licensing; Right-to-work audit trail |
| SEC-03 | E-commerce & D2C | Cross-border VAT, consumer law obligations, platform-imposed compliance windows. | VAT OSS / IOSS; Consumer rights & returns policy; Product safety & labelling |
| SEC-04 | Hospitality & Licensed Premises | Premises licensing, food safety, rolling renewals you can't reschedule. | Premises licence renewals; Food Standards Agency; PPL / PRS music licensing |
| SEC-05 | Professional Services | Regulator-recognised practice with PII, AML, and continuing professional standing obligations. | AML / KYC procedures; PII renewal & coverage; Regulator practising certificates |
| SEC-06 | Light Manufacturing | Plant safety, waste handling, EORI-linked import/export documentation. | UKCA / CE conformity; Hazardous waste consignment; EORI & customs filings |
| SEC-07 | Healthcare & Care Providers | Sector regulator at the centre, with safeguarding and DBS evidencing across every staff change. | CQC registration & inspection; DBS rolling renewals; Safeguarding policy currency |
| SEC-08 | Property & Lettings | HMO licensing, deposit protection, tenant safety certificates on rolling expiry cycles. | HMO & selective licensing; Tenancy deposit protection; Gas / EICR / EPC currency |

If a client is outside these eight sectors, Sentinel still onboards them — the operating model adapts to the client's regulators and renewal calendar.

## 8. Operating model & commercial posture

- **UK-based team.** Operators are based in the United Kingdom, working in the client's jurisdiction and time zone.
- **Continuous engagement, not contracted projects.** There is no fixed-term contract. The engagement runs month to month and can be stood down at any month boundary.
- **Operator-led, system-augmented.** Real people own each client account. Document intelligence systems handle ingestion, indexing, and alerting; humans decide what matters and own the relationship.
- **Operates between accountant and solicitor.** Sentinel is additive, not replacing. Existing professional relationships continue.
- **Response within one UK business day** to any enquiry, written or scheduled.
- **Pricing.** Custom per engagement based on operating profile (sector, document volume, regulator footprint, headcount). Quoted after the discovery call. No public pricing list; no contract lock-in.

## 9. The dashboard

Each client gets a private operations dashboard. It is a window into the work Sentinel is doing — not a tool the client has to operate. A public, illustrative version is at https://crownixsentinel.com/sample-dashboard. It includes:

- **Compliance position overview** (overall status, deadline horizon, document vault status, regulatory watch).
- **Risk posture** with severity weighting.
- **Priority actions** assigned to operators.
- **Active alerts** with severity (critical, high, medium, low) and origin (regulator, internal, system).
- **Deadlines** with countdown and owner.
- **Audit status** — what has been reviewed, by whom, when.
- **Document Vault** — categorised, version-controlled, expiry-aware.
- **Regulatory updates and watch list** — incoming guidance, assessed for impact.
- **Operator notes** — internal commentary attached to the client's record.
- **Monthly review** — scheduled call, written summary, action list.

## 10. Frequently asked questions

**Q: Is Sentinel a SaaS product?**
No. It is a continuous human-run service, augmented by document intelligence systems. There is no software the client has to operate.

**Q: Do you replace our accountant?**
No. Your accountant continues to file accounts and tax returns. Sentinel makes sure they receive what they need, on time, with the supporting documentation and signatures already organised.

**Q: Do you replace our solicitor?**
No. Your solicitor continues to advise and draft. Sentinel manages the operational lifecycle around the documents they produce — storage, versioning, expiry, renewal triggers.

**Q: What sectors do you operate in?**
Sentinel is sector-agnostic. Eight sectors are explicitly profiled (construction, recruitment, e-commerce, hospitality, professional services, manufacturing, healthcare, property), but the operating model adapts to any UK business.

**Q: Where is the team based?**
United Kingdom. Operators work in the client's jurisdiction and time zone.

**Q: Is there a contract lock-in?**
No. Engagements run month to month and can be stood down at any month boundary.

**Q: How do clients get started?**
Book a 30-minute discovery call at https://crownixsentinel.com/contact, or email contact@crownixholdings.com. Response within one UK business day.

**Q: What does the first month look like?**
Week 1: discovery, document collection, baseline compliance audit. From day one onward: ingestion into the Document Vault and continuous monitoring across the relevant regulators. End of month 1: first Monthly Position Review call and written summary.

**Q: How is Sentinel different from a fractional CFO or fractional GC?**
Fractional CFOs focus on financial strategy and reporting. Fractional GCs focus on legal advice and contracts. Sentinel focuses on the **operational lifecycle of compliance** — the deadlines, documents, filings, and regulatory monitoring that surround both. The three roles are complementary.

**Q: Is data secure?**
Documents are held in a structured vault with access scoped to the assigned operator, the client, and authorised counterparties. Standard UK data protection obligations apply (Crownix Holdings Ltd is the data controller).

**Q: Who is Crownix Holdings Ltd?**
The parent company of Crownix Sentinel. UK-registered, company number 16985396, jurisdiction England and Wales.
