Investigative mystery client in Milan.
Covert operations to document corporate infidelity, tax fraud and brand violations. Forensic dossiers with full evidentiary value, admissible before the labour judge.
Infidelity documented.

To understand the effectiveness of this corporate control tool, it is first necessary to distinguish investigative Mystery Client activity from the ordinary dynamics of commercial Mystery Shopping. While the latter pursues purposes strictly related to marketing, sales optimisation and standard measurement of customer‑satisfaction levels, the Mystery Client service designed by an authorised investigative agency constitutes a genuine defensive investigation aimed at protecting the company's assets and brand integrity.
Unexplained declines in the turnover of retail outlets, restaurants or hospitality facilities are not necessarily due to adverse macro‑economic conditions, but often stem from internal illicit conduct hidden from ownership. Arcadia Company designs targeted undercover operations, employing professional investigators able to work incognito to uncover and document instances of corporate disloyalty, tax fraud and cash skimming, providing the entrepreneur with objective, legally admissible evidence for litigation.
How a Mystery Client operation unfolds in the field
The investigative Mystery Client operation relies on the principle of controlled simulation and non‑invasive direct observation. An authorised operative infiltrates the client’s operational site, branch or point of sale, acting as a typical consumer or service user.
During the commercial transaction, the investigator monitors the behaviour of the responsible staff and verifies strict compliance with security protocols, cash procedures and corporate policies. Every anomaly or breach of contractual duties of fairness and good faith (art. 1375 c.c.) is meticulously recorded and documented, ensuring the creation of an unassailable evidential record, free from the probative limitations that affect anonymous reports.
The macro‑areas of intervention and documented offences
Unlike the statistical questionnaires provided by marketing agencies, Arcadia Company’s forensic reports focus on identifying violations that may justify dismissal or give rise to criminal liability:
- Tax fraud and cash shortages (the "Black"): detection of systematic omission in issuing receipts or fiscal tickets, aimed at the unlawful appropriation of cash paid by unsuspecting customers.
- Compliance for franchising networks and licence agreements: inspection checks to verify whether the franchisee uses trademarks or advertising materials in compliance, respects exclusive territories, or, in breach of the concession contract, introduces parallel goods not authorised by the head office into the commercial circuit.
- Quality‑assurance and brand‑reputation audit: monitoring of professionalism levels, confidentiality protection and ethical conduct of staff towards the public, detecting obstructive, offensive or grossly negligent behaviour capable of causing irreversible image damage to the company.
- Verification of security and anti‑theft procedures: simulation of vulnerable or risky situations to assess the reaction times of internal security staff and detect any collusion with individuals engaged in shoplifting or the removal of logistical stock.
Compliance with the Workers' Statute: The activation of a Mystery Client for investigative purposes is fully lawful pursuant to article 4 of Law No. 300/1970. As defensive controls aimed at protecting corporate assets from criminal conduct or fraud, they do not require any prior union agreement nor authorisation from the Labour Inspectorate, provided the investigation does not turn into continuous surveillance of the worker’s normal productivity.
Evidential value and admissibility of the dossier in court
The findings of our investigations are backed by a Prefectural Licence pursuant to article 134 of the T.U.L.P.S. (Unified Text of Public Security Laws). This means that the final Investigative Dossier is not merely an internal informational document, but constitutes a forensic expert report in every respect.
The descriptive report of the facts is accompanied by verification receipts, time‑track logs, documentary evidence and direct testimonies of the operating agents. In proceedings before the Labour Judge, the private investigator who conducted the undercover inspection may be called as a witness, attesting to the collected evidence and safeguarding the company’s dismissal measure against challenges and damage‑compensation claims.
Data processing and institutional compliance
Each infiltration and defensive monitoring operation is carried out by Arcadia Company in strict compliance with European and national privacy provisions. The data processing performed is strictly limited to what is necessary for exercising the right of defence in court, in line with the provisions and requirements of the Garante per la protezione dei dati personali.
