Accounting Common Data Model

Time consuming and tedious sorting and formatting of client data becomes a thing of the past with the Accounting CDM

What is the Accounting Common Data Model?

Developed by accountants, for accountants

Automation is easy when you know what to expect every time

The Accounting Common Data Model (CDM) provides a standard format for accounting data. Converting your client's data to the CDM structure with our Integration Engine means you see data in the same format, time after time. Users benefit from increased efficiency and can automate uploading data to analytics platforms regardless of the source system. The model is created by the market, is open-source and available via the link below.

Benefits of using the Accounting CDM

Support your data preparation

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