Keeping Add-ons in Sync with Plan Dependencies

A Plan Dependency keeps one charge's quantity (or included units) automatically in step with another. Link an add-on to your base plan's seats once, and it scales with every change — so an add-on never drifts out of sync, and you never quietly under-bill.

Where to find it

Go to Rules & Automation → Plan Dependencies. Each dependency ties a source charge to one or more targets, and keeps them in step whenever the source changes.

Build a dependency

1. Select New Dependency.

2. When this changes — pick the source: the charge whose quantity drives the rule (for example, your Premium plan's Seats).

3. Keep these in sync — add the target charge that should follow (for example, an add-on's compute or storage blocks).

4. Choose how the target is calculated:

   • Match exactly (1:1) — target equals source (5 seats → 5 units).

   • Multiply by a factor — target = source × factor (factor 2, 5 seats → 10 units).

5. Set the direction (one-way, source → targets) and activation (always, or only when the target is present).

6. Save. The plain-English preview and worked example show exactly what will happen — try a value to see the math.

What it looks like

The worked example calculates a sample for you: with a two-to-one ratio, 25 seats becomes 50 blocks. Because the rule runs automatically, the add-on stays correct the instant seats change — no spreadsheets, no manual updates.

Tip: Dependencies are one-way by default (the source drives the targets). Use two-way only when editing either side should update the other.
