Mews supports two main environments: Demo and Production. Demo can be used for integration development and testing. Production is for live customer sites.
Enterprises can be configured for Gross Tax or Net Tax. In the Production environment this will depend on the individual enterprise. For development and test purposes, we have set up two versions of the Demo environment, one for Gross Tax and one for Net Tax.
- Gross Pricing Environments: These are environments in which taxes are included in the pricing that is offered to the end customer, such as used by Germany, UK and Australia.
- Net Pricing Environments: These are environments in which taxes are excluded from the pricing that is offered to the end customer, such as used in the USA.
IMPORTANT! The demo environments are completely public and NO REAL DATA should be used for any reason. Failure to comply with these guidelines can result in immediate suspension of the connection or denial of certification.

Each enterprise operates within a specific Tax environment, which defines the applicable Taxations. The tax rates are represented by Tax rate codes accepted within that environment.
Instead of using numeric tax rates like 0.1
, use Tax rate codes such as AT-S
to accurately represent and calculate the correct taxation for each accounting item in Mews.
To obtain the applicable codes:
- Download the enterprise information using Get configuration to identify the Tax Environment.
- Filter for the applicable Tax rate codes from the tax environment information retrieved via Get all tax environments.
- Be sure to note the validity intervals, and monitor any government announcements for changes to tax rates. If changes occur, re-retrieve the enterprise and tax environment information to identify the new tax rate codes.
Allowlisting (formerly called 'whitelisting') is a common security measure which can be applied to a system to allow only specified external systems to talk to it. This has traditionally been achieved using IP address-based firewall rules. However, this approach does not work with modern cloud based architectures, which use dynamic and shared IP addresses, proxy servers and elastic resources. For this reason, we do not support the use of IP address allowlists for our APIs and we cannot supply a list of IP addresses for our APIs.
