Cumulative impact
Cumulative estimate based on confirmed data
How impact is calculated
Subscription savings
The current cumulative monetary total includes the HR system: at $3,000 per month since 14 July 2026
Partial calendar months are prorated by elapsed time in Moscow
Time is counted separately
The HR system uses a conservative estimate: 2 hours per employee × 10 new employees per month, since launch
This is a calculated estimate, not time-tracker data — the value of hours is not added to money
Other outcomes are in the case studies
The advertising system’s rate is confirmed, but its savings start date has not yet been established
Receivables recovery, advertising budgets and the tender analyst’s estimated avoided cost are not combined with subscription savings
Data and recalculation
Source data verified 21 September 2026 · calculation as of 22 September 2026
Linear data updated 22 September 2026
When a project stops, its cumulative impact is retained and further accrual ends
