Extension Offers
Retain trial users by extending their trial period — configure extension length and target the trial-to-paid conversion moment.
Extension offers give trial users more time before their first payment. When a subscriber on a trial plan initiates cancellation, an extension offer delays the billing start date, giving them additional time to experience value and convert to a paid subscription.
When to Use Extension Offers
Extension offers are specifically designed for the trial-to-paid conversion moment. They work best when:
- The subscriber is still in a free trial or introductory period
- They haven't fully explored the product yet
- Their cancellation reason suggests they need more time rather than a different price
| Cancellation Reason | Extension Effective? | Why |
|---|---|---|
| Haven't had time to try it | Yes | More time directly solves the problem |
| Not sure it's right for me | Yes | Extended evaluation period |
| Too expensive | No | Use a discount instead |
| Missing features | No | More time won't add features — consider downgrade |
| Found a better alternative | No | They've already decided — use a discount |
Extension offers are not appropriate for subscribers who are already on a paid plan. For those subscribers, use pause, downgrade, or discount offers.
Configuring Extension Length
Set the number of additional days added to the trial when configuring an extension offer:
| Extension Length | Best For |
|---|---|
| 7 days | Subscribers who are close to converting but need a small push |
| 14 days | The most common choice — enough time for meaningful exploration |
| 30 days | Complex products where onboarding takes longer |
The extension is stored in the duration_days field on the offer.
Choosing the Right Length
Consider your product's typical time-to-value when selecting an extension length:
- If most subscribers who convert do so within the first week, a 7-day extension is sufficient
- If your product requires setup, integrations, or team onboarding, a 14- or 30-day extension gives enough runway
- Check your existing trial conversion data to see when most conversions happen, and extend just past that point
How Extensions Work
When a subscriber accepts an extension offer:
- LostChurn records the acceptance on the cancel flow session (
accepted_offeris set) - A discount redemption record is created to track the extension
- The trial end date on the subscription is pushed forward by the configured number of days
- The subscriber continues using the product without any billing until the new trial end date
- When the extended trial ends, normal billing begins automatically
What the Subscriber Sees
- A clear message explaining that their trial has been extended (e.g., "You've got 14 more days free")
- The new trial end date
- Reassurance that no charges will apply until the extended trial ends
Creating an Extension Offer
- In the flow builder, add an Offer step
- Select Extension as the offer type
- Configure the settings:
- Extension length — Number of days to add (7, 14, or 30)
- Headline — The message shown (e.g., "Need more time? It's on us.")
- Description — Explain what the extension includes
- CTA text — The accept button label (e.g., "Extend My Trial")
- Set the Trigger Reason to connect this offer to the appropriate survey response
- Save the step
Combining with Other Strategies
Extension offers can be part of a broader retention strategy:
- Extension + onboarding nudge — When a subscriber accepts an extension, trigger an onboarding email sequence to help them get more value from the product during the extended period
- Extension + discount at trial end — If the subscriber reaches the end of the extended trial and still hasn't converted, offer a discount on the first paid month
- One extension only — To prevent abuse, limit extension offers to one per subscriber. LostChurn checks previous redemptions before presenting the offer
Tracking Extension Performance
Monitor extension offers in the saves dashboard:
| Metric | Description |
|---|---|
| Extension acceptance rate | Percentage of trial subscribers who accept the extension |
| Conversion rate after extension | Percentage of extended subscribers who convert to paid |
| Time to convert | Average days from extension acceptance to paid conversion |
| Revenue from extended trials | Total MRR generated by subscribers who converted after an extension |
The key metric is conversion rate after extension. If extended subscribers convert at a rate close to or higher than your baseline trial conversion rate, the extension strategy is working. If the conversion rate is very low, subscribers may be using the extension as a delay tactic before ultimately churning.
