For Mercury and its exports to display costs accurately and transparently, the interaction between billable volume (e.g., impressions, clicks, conversions) and the cost sync is essential.
1. Cost sync is active, but no actual volume is recorded
When cost sync is enabled, the actual costs from the connected system are generally imported. However, to correctly and transparently distribute those costs on a daily level, a realized billable volume must be provided—either through import or manual entry on the plan item.
If no actual volume is recorded:
- Mercury will show the correct total cost,
- but the daily distribution of costs will be automatically calculated by Mercury, rather than based on actual measured data.
- This means: The total sum is correct, but the daily values do not reflect the actual measured values.
2. No cost sync and no actual volume
If no cost sync is set up and there is no realized billable volume, Mercury cannot calculate costs. In this case, no realized costs will be displayed—neither on the plan item nor in the export.
