Understand tiers and carrier limits
Your subscription tier caps how many active carriers and libraries your organization can have, and unlocks features as you grow. Only active (non-archived) carriers count toward the carrier cap.
Billing is at the organization level. Every library and carrier lives under one organization, and that organization is on a single tier.
The tiers
There are four tiers. Prices below are display values — the real charged amount always comes from Stripe at checkout.
| Tier | Price | Active carriers | Libraries | Equipment |
|---|---|---|---|---|
| Free | $0 | 10 | 1 | 10 |
| Starter | $10/mo ($100/yr) | 30 | 1 | 10 |
| Pro | $25/mo ($250/yr) | 75 | 3 | 25 |
| Plus | $40/mo ($400/yr) | 500 | Unlimited | 150 |
Annual billing works out to ten months’ price (two months free).
Each tier also unlocks features:
- Free — loans, holds, due dates, and email reminders.
- Starter and up — waitlists, renewals, and events with packing lists.
- Pro and up — advanced reporting, and the Financial Tools add-on (a paid add-on).
How the carrier limit works
The limit counts active carriers only. A carrier that’s Available, On loan, Out for Repair, or Reserved counts. An Archived carrier does not — archiving a carrier frees up a slot.
When you try to add a carrier, Carrier Stash checks your remaining slots first and tells you if your plan is full. It checks the cap both in the form and at the database level, so the count can never be exceeded — even during a bulk import.
Equipment items have their own separate cap and never consume carrier slots.
What happens when you hit the limit
At exactly the cap, you simply can’t add another carrier or library until you archive something or upgrade.
If you drop over the limit — usually after a downgrade or a trial ending — the affected areas go read-only. Existing loans keep working and check-in still works, but you can’t add carriers or create libraries until you’re back under the limit or you upgrade. This is called soft lock.
