When your research needs grow beyond the number of participants you originally ordered, you don’t need to start over. The Audience Extension feature lets you top up an existing panel order directly from the Recruit tab, so you can keep collecting interviews without interrupting your study.

​
When to Use Audience Extension

Use this feature when:
  • You’ve filled your initial order but need more data points to reach saturation
  • New research questions emerge mid-study that require a larger sample
  • You want to extend a segment that performed especially well in screening
You can add a maximum of 20 participants per extension. If you need more than 20, complete one extension checkout first, then repeat the process.

​
How to Add More Participants

1

Open the Recruit tab

Navigate to the Recruit tab inside your project and click Orders to see all panel orders for this study.
2

Open your order

Find the panel order you want to extend. Click the three-button dropdown on the right-hand side of that order row, then select View. A screen showing your full order details will appear.
3

Click Add Participants

Locate the Add Participants button on the order details screen and click it.
4

Enter the number of additional interviews

Enter how many additional interviews you’d like to collect. Remember the maximum is 20 at a time.
5

Complete checkout

Review your order and check out using your corporate card or request payment via invoice.
If you need more than 20 additional participants, complete the first extension checkout and then repeat these steps as many times as needed.

​
What Happens Next

Once your extension order is placed, Strella adds the new participant slots to your existing order. Recruiting resumes automatically — new qualified participants are invited according to your existing screener and scheduling settings, with no further action required from you.
