Audit Common Data Model

Providing a shared data language for business and analytical applications to use

What is the Audit Common Data Model?

Developed by auditors, for auditors

A simple explanation

The Audit Common Data Model (CDM) provides a standard format for accounting data, designed in partnership with industry. Converting your client's data to the CDM format with our Integration Engine means you see data in the same format, time after time. Users benefit from increased efficiency and can upload data to analytics platforms in the same way, regardless of source system. The Audit CDM comes in both CSV (for Excel) and JSON formats. To access the model on our GitHub site, follow the link below.

Benefits of using the Audit CDM

Support your data preparation

The Audit CDM standardises data into a common format, regardless of source, supporting your data preparation.

Easier reconciliation

Viewing data in a common format means you can quickly combine data to make reconciliation easier.

Data comparison

The Audit CDM helps you compare like with like, such as this year's balances with last year's, without having to manipulate or prepare the datasets.

Co-developed by industry

We created the Audit CDM together with audit firms, regulators, academic institutions and Microsoft. The model is open source and owned by everyone.
