MRR trend chart in the admin dashboard

The admin revenue view was a single number. Good for a snapshot, not great for spotting trends. We fixed that.

There's now a 90-day MRR area chart at the top of the admin dashboard. It plots monthly recurring revenue over the trailing three months, broken down by plan tier. You can see at a glance whether growth is coming from starter upgrades, pro conversions, or the enterprise tier moving.

A few details on what's shown:

• Each plan tier is its own color in the stacked area
• Hovering a point gives you the exact MRR for that tier on that date
• The chart updates daily, not real-time, so the right edge is always yesterday

This is the same data that was already in the system. We just stopped hiding it behind a single aggregate number and made it readable. Net new MRR and churn MRR breakdown is coming in a follow-up.
