Three things this store should know
The data holds real problems and opportunities, the way yours does. Ask the analyst to find them — it is not told the answers.
- REVENUE
Sales fell off for a few days
Daily revenue dropped sharply for several days, then came back. Something specific caused it.
“Why did revenue dip for a few days recently?”
- QUALITY
One product keeps coming back
Refunds look normal across the catalog except for one item. Which one, and since when?
“Which product has an unusually high refund rate?”
- GROWTH
A new market is waking up
Signups from one country took off last month. Find where, and how fast.
“Which country's signups grew the most in the last month?”
Every answer can be checked
- READ-ONLY
It cannot change data
The analyst connects with a role that can only SELECT, inside a read-only transaction with an 8-second timeout.
- SQL
The query comes with the answer
Every chart carries the SQL that produced it. Open it, copy it and run it yourself.
- DEFINITIONS
Numbers follow your rules
On your own connection Supalens reads your code to learn what counts as revenue or a refund, and answers with those definitions.
A useful answer becomes a monitor
When a number matters, approve it as a monitor. Supalens checks it on your plan's schedule and explains what changed when it breaks.
