Diligence is the only XBRL reporting tool with native ONEGATE synchronisation — covering every ACPR mandate from COREP and FINREP to RUBA, AnaCredit, and Pillar 3. Used by banks and fintechs across France.
The Autorité de Contrôle Prudentiel et de Résolution (ACPR) supervises banks, investment firms, payment institutions, and insurance companies operating in France. Institutions subject to ACPR oversight must submit a range of prudential and statistical reports on a regular basis, the majority of which are transmitted via the ONEGATE portal using structured XBRL or XBRL-CSV formats.
The principal reporting frameworks applicable to French institutions include:
Submission calendars are set by the EBA, ECB, and ACPR. Quarterly COREP and FINREP reports are typically due 45–60 days after the reference date. AnaCredit monthly submissions are due within 30 days of the reference date. Missing a deadline or submitting a report with validation errors triggers automatic alerts within ONEGATE and can prompt supervisory follow-up.
ONEGATE is the ACPR's electronic collection portal, operated in partnership with the Banque de France. It serves as the single entry point for all ACPR and Banque de France supervisory reporting. All significant reporting frameworks — COREP, FINREP, RUBA, AnaCredit, Solvency II QRTs — route through ONEGATE.
An institution prepares its XBRL or XBRL-CSV instance document using its reporting tool. The file must conform to the applicable EBA or EIOPA taxonomy. Before submission, the file should pass DPM validation to eliminate blocking errors. The validated instance document is then deposited in ONEGATE via the API or the web interface. ONEGATE processes the file, applies additional ACPR validation rules, and returns a status: accepted, accepted with warnings, or rejected. Institutions receive a formal acknowledgement for accepted filings.
ONEGATE uses a certificate-based access model. The institution's ONEGATE administrator manages user accounts, role assignments, and submission authorisations. Multiple users can have different access rights — preparer, validator, and submitter roles are common configurations. Managing these access rights correctly is a compliance requirement in its own right.
The EBA and EIOPA release updated XBRL taxonomies typically once or twice per year. Each new taxonomy version introduces new or modified data points, changed validation rules, and updated DPM structures. Institutions must migrate their reports to the new taxonomy version by the date ACPR activates it in ONEGATE. Late or failed taxonomy migrations are among the most common causes of submission errors in France.
XBRL Connect is Diligence's dedicated ACPR filing monitor. It connects natively to ONEGATE, giving your compliance team live visibility into every submission without manual log-ins to the portal.
For institutions running SAB core banking systems, Diligence's Core Banking Connector automates the entire pipeline from source data extraction to ONEGATE submission — without manual data handling or intermediate spreadsheets.
The Core Banking Connector integrates natively with SAB (AT Consulting's core banking platform, widely deployed in French mutual banks and savings institutions). It extracts the relevant accounting and risk data from SAB in its native format, transforms and maps that data to the XBRL taxonomy required by the target report, and submits the completed instance document directly to ONEGATE. The full cycle — extraction, transformation, validation, submission — runs as an automated workflow.
The Core Banking Connector is deployed on-premises within the institution's own infrastructure. No source data leaves the institution's environment. This architecture meets the data residency and sovereignty requirements common in French public sector banking and mutual group structures.
The most common source of ACPR filing errors is manual data extraction and transformation. By connecting SAB directly to ONEGATE with validated transformation logic, the Core Banking Connector removes these failure modes from the reporting chain.
Regulatory reporting is the entirety of what Diligence does. ACPR-specific features — ONEGATE native sync, SAB extraction, RUBA and AnaCredit support, French-specific DPM validation — are first-class capabilities, not afterthoughts on a broader banking platform.
Diligence's support team is available in French. The median first response time is 23 minutes, with a 100% answer rate. This matters particularly when a COREP quarterly deadline is within 48 hours and a validation error is blocking submission.
XBRL Express is built for compliance teams to operate directly, without external XBRL consultants or system integrators. Most institutions complete migration and submit their first reports within days of starting.
For institutions that cannot route source data through a cloud environment — cooperative banks, public-sector entities, institutions with strict ACPR operational resilience frameworks — Diligence offers on-premises deployment of the Core Banking Connector.
Diligence serves over 200 banks, fintechs, investment firms, and insurers across France, Belgium, Luxembourg, and six other European countries, tested across every major ACPR reporting cycle and multiple taxonomy versions.

ONEGATE is the ACPR/Banque de France portal for all supervisory reporting submissions. French institutions must use it for COREP, FINREP, RUBA, AnaCredit, and Solvency II QRT submissions — it is the only authorised entry point with no alternative submission channel.
Diligence supports the current and previous EBA CRD and EIOPA Solvency II taxonomy versions. Updates are included automatically in XBRL Express — institutions do not need to manually install new taxonomy versions or update their reporting templates.
Most institutions complete migration and submit their first production reports within 3–10 business days. Diligence's onboarding team provides a structured migration process including taxonomy mapping, validation testing, and ONEGATE connectivity setup.
Yes. Diligence's ACPR suite covers COREP, FINREP, RUBA, AnaCredit, Solvency II QRTs, and Pillar 3 — all managed in XBRL Express and submitted via a single ONEGATE connection.
Join 200+ European institutions already using Diligence for regulatory reporting. COREP, FINREP, RUBA, AnaCredit — all in one platform, directly connected to ONEGATE.
