Booking add-ons requires the Owner or Admin role and an active paid subscription. Most add-ons require the Business plan; Sleek Intelligence credits can also be topped up on Starter. Add-ons are not available on the free plan or during a trial without a paid subscription. On Enterprise, your account manager handles add-ons.
Available add-ons
Each add-on is booked in fixed increments (for example, one seat at a time, emails in blocks of 5,000, credits in blocks of 10,000). The exact increments and live prices for your plan and currency are shown in the Manage add-ons dialog.
How to book an add-on
1
Open the Manage add-ons dialog
Go to Settings → My Account → Billing and, in the Plan section, click Add-ons.
2
Choose how much of each add-on you want
For each add-on, pick a quantity from its dropdown. Only add-ons available on your current plan are shown. Set an add-on back to
0 to remove it.3
Review the live cost preview
As you change quantities, Sleekplan shows a live preview of the invoice, including the line items and the total. Prices are shown before tax.
4
Book the add-ons
Click Book add-ons. If your bank requires extra verification (3-D Secure), you will be prompted to confirm the payment. Your raised limits take effect right away.
Billing and timing
- Adding or increasing an add-on is charged immediately. For the email, popup, and announcement add-ons, the mid-cycle charge is prorated to the time left in your billing period.
- Reducing or removing an add-on is scheduled for the end of your current billing period, so you keep the extra capacity you have already paid for until then.
- Add-on charges appear as separate line items on your invoices.
