Introducing Free Trials in Clerk Billing

Clerk Billing now supports free trials to help developers boost conversion rates and reduce buyer friction.
Let’s face it: a frictionless billing system is great, but giving users a risk‑free peek at premium features can turn hesitation into conversion.
Clerk Billing was designed to take the same great developer experience we built for implementing authentication and apply that philosophy to subscription-based billing. It allows developers to drop in a single <PricingTable /> component to display a beautiful pricing table that is typical across hosted SaaS applications. Selecting a tier prompts the user to enter their payment information and once processed, any entitlements configured with their selected plan are flagged on their account for you to easily allow access to gated content.
With the addition of free trials, your users can now more easily experience premium features of your app to decide if it's the right fit for them before automatically converting to paid customers. In this article, we'll explore why you should use free trials for your app and how to implement it with Clerk Billing.
Free trials lead to higher conversions
Free trials reduce buyer friction and drive higher conversion rates by removing the immediate financial commitment. The data is compelling: SaaS trial-to-paid conversion rates average around 25%. In B2B SaaS, opt-out trials (requiring credit card upfront) can reach nearly 49% conversion, while opt-in trials typically convert around 18%.
Beyond metrics, free trials create product-qualified leads (PQLs) who've actively engaged with your product. This makes conversion rates a reliable gauge of real value while reducing churn from sign-up to paid status.
Best practices with free trials
Allowing users to try your product for free is enough to increase conversion rates; however, there are a few considerations to maximize the impact. One practice is to test different trial lengths and models to optimize your conversion rates. By trying a few different trial periods and measuring the conversion rate, you can fine-tune what period leads to the highest revenue increase.
Another practice is to set realistic trial periods. For most SaaS applications, 7–14 days is a great starting point. If you have a more complex app, extending the period beyond that range could result in higher conversions due to the steps involved in utilizing the SaaS most effectively.
Trial periods present a perfect opportunity to engage users through product education. This can be through a very polished onboarding experience within the app, or something more traditional like using a newsletter platform for a drip campaign during the trial period to provide ways in which your app can be used.
As with most optimizations, success depends on rigorous measurement and iteration. Track key metrics like trial-to-paid conversion rates and analyze performance across different trial lengths and content strategies.
How to configure free trials using Clerk Billing
If you've not yet used Clerk Billing, configuring subscriptions is as simple as defining your subscription plans, associating the proper features with each plan, and adding the <PricingTable /> component to your application.
The following screenshot demonstrates what a three-tier pricing table would look like for a task management app:
And the code for this page (built with Next.js) looks like this:
import { PricingTable } from '@clerk/nextjs'
export default function Home() {
return (
<div className="min-h-screen items-center justify-items-center gap-16 p-8 pb-20 font-sans sm:p-20">
<PricingTable />
</div>
)
}Free trials can now be enabled for individual plans within the Clerk dashboard:
Once configured, the <PricingTable /> component in your app will automatically update to reflect the plans where a free trial is available. You don't even have to make any changes to the code in your application.
When a user wants to trial a plan, they'll still be prompted for their payment information so that they can transition to a paying customer once the trial period ends. Your customers will automatically be notified when their trial period is coming to an end.
If you handle your own messaging, you can also use the subscriptionItem.freeTrialEnding webhook to be notified when a customer's trial is ending so you can notify them or handle it accordingly. Below is a sample of the payload sent when a trial period is ending.
