Once the timer ends

Once Timer Ends is on the Content tab. The options you're offered depend on your timer type and countdown type — the app only lists actions that can actually work for your combination.

Set it

Open the timer and go to the Content tab.

Find the Once Timer Ends dropdown.

Choose an action.

If you chose Show Custom Title, enter the Custom Title text.

Click Save.

The actions

Action	What happens at zero
Hide Timer From User	The timer disappears from the page
Show Custom Title	The timer is replaced by your custom message
Repeat Countdown	The countdown starts over from the full duration
Do Nothing	The timer stays on screen showing zero
Delete All the items in the cart	The customer's cart is emptied

Which actions are available

Timer / countdown type	Options offered
Cart page + fixed minutes	Repeat Countdown · Hide Timer From User · Delete All the items in the cart
Cart page + other	Hide Timer From User · Delete All the items in the cart
Any other type + fixed minutes	Hide Timer From User · Show Custom Title · Repeat Countdown · Do Nothing
Any other type + date or recurring	Hide Timer From User · Show Custom Title · Do Nothing

Two rules explain the whole table:

Repeat Countdown needs fixed minutes. A date-based or recurring countdown derives its remaining time from configured dates, not from when the visitor arrived, so there is nothing to restart.
Deleting the cart is cart-page only. It's the only place emptying a cart makes sense.

Your existing choice is never overwritten

If you already have a working action selected that this combination wouldn't normally list, the app keeps it and adds it to the dropdown rather than silently changing your setting. Only an action that provably cannot run is rewritten — and it becomes Do Nothing, never Hide or Delete.

Show Custom Title

The most useful option for a finished campaign. Instead of vanishing or freezing at zero, the timer says something purposeful:

This sale has ended — see what's new
Pre-orders are now closed
Back tomorrow at 9am

Set Once Timer Ends to Show Custom Title.

Type your message into the Custom Title field that appears.

Click Save.

Delete All the items in the cart

This empties the customer's cart. It is only offered on cart page timers, and it should be used sparingly — a customer who loses a full cart usually doesn't rebuild it. Say clearly in your title that it will happen, and give a generous duration.

Tip

Test your end action before publishing. Set a fixed-minute timer to 1 minute, watch it reach zero on your storefront, then set the real duration.
