How do you handle auto-charge conversion tracking for SaaS trials that upgrade automatically
Posted by on October 9, 2025 at 10:52 amUsers in my SaaS pay $1 for a trial.
After 3 days, they are automatically charged different amounts (depending on the plan they chose). Basically, they pay $1, and after 3 days (or once they use up their trial credits), they are charged $19, $39, or $99 per month.Currently, I send a
purchase_successevent for the $1 trial, with a conversion value of $1. This event fires when a user successfully completes a payment through Stripe.
After that, I don’t fire any other events — and I feel like I’m missing out on valuable revenue data that could be sent back to the ad platforms to help them find higher-value users.My goal is to send back to Google and other ad platforms the actual amount charged during the auto-renewal (e.g., $19, $39, or $99).
Should I send an additional event (for example,
purchase_plan_autocharge) with the correct conversion value?
Or are there other recommended approaches for handling auto-charge / recurring billing events? -

You need to send a Google Offline Conversion when the auto-charge gets triggered for whatever the average lifetime customer value is for each of those plan tiers.
