# Create and Compare Cost Snapshots

Use snapshots to preserve a cost picture and explain how the project position changed between reporting moments.

### Create a snapshot

{% stepper %}
{% step %}
Confirm project scope, data freshness and exchange basis.
{% endstep %}

{% step %}
Resolve known changed-order or import exceptions.
{% endstep %}

{% step %}
Select `Create Snapshot`.
{% endstep %}

{% step %}
Choose the project scope requested by your reporting procedure.
{% endstep %}

{% step %}
Create the snapshot after the reporting cut is ready.
{% endstep %}
{% endstepper %}

### Compare versions

{% stepper %}
{% step %}
Open `Snapshots`.
{% endstep %}

{% step %}
Select `Compare Versions`.
{% endstep %}

{% step %}
Choose the project, Snapshot A as the base and Snapshot B as the compared version.
{% endstep %}

{% step %}
Select `Compare` and review the movement.
{% endstep %}
{% endstepper %}

{% hint style="warning" %}
**Comparison rule.** Only closed snapshots can be compared.
{% endhint %}

### **Exchange-rate behavior**

Closed snapshots retain the exchange rates active at closure. Later rate changes do not retroactively alter the closed historical picture.
