# FAQ

<mark style="background-color:blue;">**Which system is the Single Source of Truth?**</mark>\
To avoid discrepancies and allow consistent data depending on what's the core business of the partners software there needs to be on Single Source of Truth. For e.g. if there is being integrated an ERP system with EverReal the SSoT is the ERP system.&#x20;

<mark style="background-color:blue;">**With what frequency will the data be transferred?**</mark> \
How often will data be imported should be clarified already from the beginning. The recommended frequency is once a day for data which is not changing that often as for e.g. terminations of contracts.&#x20;

{% hint style="info" %}
A real time synchronisation of master data won't be supported. In case there is a valid reason a real time synchronisation should be considered EverReal should have a detailed overview provided with it.&#x20;
{% endhint %}

<mark style="background-color:blue;">**Does the integration aim to be bi-directional?**</mark>\
For bi-directional integrations there should be a documentation what possibilities are provided by the partners software. This should be clear before the integration start.&#x20;

<mark style="background-color:blue;">**Is a detailed description of goals & time plan available?**</mark>

A detailed description of the integration goals should be provided to EverReal after deciding on the integration type (API or CSV files) with all the required fields. \
