The numbers that say whether the thing works, in one place
Most businesses are not short of data. They are short of one version of it. Five exports that nobody reconciles is not reporting, it is an argument waiting to happen every month.
Data model and schema design
The part that decides whether every later question is easy or expensive. Done once, carefully, before it hardens into something nobody dares change.
Reporting dashboards
The handful of numbers a decision actually turns on, updated automatically. Not a wall of charts that everyone stops opening after the second week.
Analytics setup, privacy-first
Measurement that does not require a cookie banner the size of the page. You get the numbers you need and your visitors keep their privacy.
Migration off spreadsheets
Moving the history without losing it, including the special cases hidden in colour codes and comments that no export will carry.
Companies reporting from memory
If the monthly number depends on who assembled it, the number is an opinion. Making it reproducible is usually a week of work.
Teams with data in four places
Shop, accounting, courier, spreadsheet. Each is right about its own part and none of them agree on the total.
Anyone who does not know what to measure
Starting with the decision rather than the chart. Two numbers you act on beat forty you look at.
Start with the scope conversation. It costs nothing and it is usually one call.
