Add-ons
Add-ons are paid extensions you can layer on top of your Nembl plan: extra capacity, optional features, and packaged integrations. They bill separately from your base subscription and are managed independently.
Open from Admin → Add-ons.
For your base plan and core subscription, see Plans & Pricing.
Add-on types
| Category | Examples |
|---|---|
| Capacity | Extra Workflows beyond your plan limit, extra Inboxes, extra Forms, additional chatbotMsgsPerMonth |
| Feature | Premium AI Agents (e.g. higher-tier providers / models), advanced analytics dashboards, longer audit retention |
| Integration | Pre-built connectors to specific vendors (Slack, GitHub, Jira, ServiceNow) without custom configuration |
| Compliance | SOC 2 evidence pack, ISO 9001 audit support, dedicated tenant |
What's available depends on your plan tier — Starter has fewer add-ons than Business.
Browsing add-ons
The Add-ons page shows two sections:
Available
Add-ons your plan is eligible for but hasn't enabled yet. Each card shows:
- Name + icon
- Short description
- Price — typically per-month, occasionally per-use
- Detail link — opens a modal with the full description, what it includes, and any prerequisites
- Enable button — adds it to your subscription on the next billing cycle (or immediately, with prorated charge, depending on the add-on)
Enabled
Add-ons currently active on your account. Each card shows:
- Name + status —
ACTIVE,PENDING_ACTIVATION,EXPIRES_<date> - Started on — when you enabled it
- Renewal date — next billing
- Usage (for capacity add-ons) — e.g. "12 / 25 extra workflows used"
- Manage — open detail to disable, change quantity, or view invoices
Enabling an add-on
- Find the add-on in Available
- Click Enable
- Confirm the price and effective date in the dialog
- Click Confirm
The add-on activates immediately for feature add-ons, or on the next billing cycle for capacity add-ons (with optional prorated charge — check the dialog).
Disabling
Open the add-on from Enabled, click Disable. Most add-ons disable at the end of the current billing period (you keep what you paid for); a few — usually one-time packaged integrations — disable immediately and refund unused time pro-rata.
If the add-on adds capacity (extra Workflows / Inboxes / etc.) and disabling would put you over your base-plan limit, Nembl flags this in the confirm dialog. You'll need to deactivate the surplus entities first, or accept that they'll be flagged as over-quota until you upgrade.
Billing & invoicing
Add-on charges roll up into the same monthly Stripe invoice as your base subscription. Line items make it explicit which charge is the base plan and which is each add-on. See Subscriptions for invoice access and payment-method management.
