MVP Free Trial With or Without a Card: What Your Build Needs

Card or no card: the comparison

This is the choice that shapes your signup, your access rules and what your app does on the last day of the trial. The details below come from Stripe's guide to free trials and its trial offers documentation.

• Signup friction. Card required at signup: higher. No card at signup: lower.
• Stripe Checkout setup. Card required at signup: subscription Checkout with a trial. No card at signup: the same, plus payment_method_collection=if_required.
• Fake or throwaway signups. Card required at signup: a card filters many of them. No card at signup: Stripe recommends an account and a captcha before the trial starts.
• What happens at trial end. Card required at signup: Stripe invoices and charges the card on file. No card at signup: you choose to create an invoice, cancel or pause.
• Screens your app needs. Card required at signup: a payment step during signup. No card at signup: an "add your card" screen, before and after the trial ends.
• Access states to handle. Card required at signup: trialing, active, past due. No card at signup: the same, plus paused or cancelled for trials that ended without a card.
• Reminder before the trial ends. Card required at signup: recommended. No card at signup: essential, because it's your main chance to get the card.

Option 1: card at signup

This is the simpler build. The payment step lives in onboarding, and Stripe handles the end of the trial. What it changes in your MVP:

• A payment step in signup. Usually Stripe Checkout, or Stripe Elements if you want the form inside your own screens.
• An automatic first charge. When the trial ends, Stripe creates an invoice and tries to charge it about an hour later, according to its free trial documentation.
• Webhooks your backend must handle. At minimum, the trial ending soon, the subscription changing and a payment failing. Your database must match Stripe's status, or users lose access they paid for.
• One rule for a failed first charge. The card on file can still be declined. Your app needs to know what that user sees.

Who a card at signup tends to suit

Products where the value shows up in the first session, and buyers who expect to pay for a work tool. A card at signup also means fewer users try the product. Decide whether you want more trials or more qualified ones.

Option 2: no card at signup

More people start the trial. Your app does more of the work. Here is what the build needs, step by step:

• 1. Make the card optional in Checkout. Stripe does this with payment_method_collection=if_required on a subscription Checkout session.
• 2. Pick what happens when a trial ends without a card. Stripe gives three options for missing_payment_method. create_invoice, the default: Stripe creates an invoice, and the subscription goes past due if nothing pays it. cancel: the subscription ends, and Stripe sends customer.subscription.deleted. pause: no invoices are created, Stripe sends customer.subscription.paused, and the same subscription can resume once the user adds a card.
• 3. Build the "add your card" path. Stripe suggests listening for customer.subscription.trial_will_end, then sending the user to the Stripe Customer Portal to add payment details. A paused subscription can also resume from the portal or from Stripe's hosted invoice page.
• 4. Set up the reminder. By default, trial_will_end fires 3 days before the trial ends, and you can change that in the Dashboard. Stripe's hosted reminder emails go out 7 days before the end.
• 5. Guard the signup. Stripe warns that trials without a card make it easier for spammers to create fake accounts. It suggests requiring an account and a captcha first.

Which end behavior fits a v1?

Each one is a single Stripe setting. The build work is in your app, which must treat that state the same way on every screen that checks access.

• Pause is the friendliest for users who come back late. They add a card and pick up where they left off.
• Cancel gives you the simplest states to handle. A returning user starts a new subscription.
• Create an invoice keeps the subscription alive as past due, so your app needs a clear rule for what a past due user can still do.

A third model: the paid trial

Stripe also offers a Trial Offer API for discounted introductory periods. Its own example is $1 for the first week. A paid trial charges straight away, so the subscription follows the normal payment lifecycle instead of a "trialing" status. Two limits matter for scoping, according to Stripe's trial offers documentation. So if you want a paid trial with Stripe Checkout, check this first. It decides whether your signup uses Stripe's hosted pages or a flow built in your own app.

• It needs API version 2026-09-30.endive or newer, and the flexible billing mode.
• Checkout, Payment Links and Elements with Checkout Sessions don't support trial offers. Stripe points those integrations to its older free trial setup with trial_end.

After the trial: keep it short in v1

Once trials turn into paying subscriptions, a new set of questions starts: failed payments, retries, reminder emails and users who cancel. Stripe's Smart Retries already handle a large part of failed payment recovery. Cancel flows, pause offers and discounts are product decisions. They're easier to get right once you know why real users leave. We cover billing and retention features separately in our feature cost guides. For a v1, the trial model above is the decision that changes your build the most.

Mobile apps: Stripe or store billing?

On iOS and Android, how you sell a digital subscription inside the app depends on Apple's and Google's rules. Those rules vary by country and have changed in recent years. Often the answer is in-app purchase through the stores, usually managed with a tool like RevenueCat. Stripe stays the default for web apps and for selling outside the app. This changes the card question. With store billing, the user starts the trial with their Apple or Google account, and the store takes the payment. The card or no card choice mostly applies to your web signup. Your app still has to read the subscription status and apply the same access rules on every platform. Our services page lists "Push + RevenueCat / Stripe when you sell" for mobile apps. On the call, we check which one your app needs. For the mobile side in more detail, see build a mobile app.

Should my MVP ask for a card during the free trial?

It depends on what you want to learn first. A card at signup gives you fewer trials, but the users who start one are more serious. No card gives you more trials, and your app has to do more work to turn them into paying users.

Does a trial without a card make the MVP harder to build?

It adds work but doesn't change the project. You need an optional card in Checkout, an "add your card" screen, one more access state for trials that end without a card, and a reminder before the end. Each part is small, but each one has to be planned from the start.

What happens in Stripe when a no-card trial ends?

It follows your missing_payment_method setting. The default creates an invoice, and the subscription goes past due if it isn't paid. You can also cancel the subscription or pause it until the user adds a card.

Can I switch from no card to card later?

Yes. For new signups it's mostly a change in your Checkout session. Stripe's API also lets you update the trial settings of existing subscriptions. The part that changes in your app is the signup screens and the access rules.

Do iOS and Android apps work the same way?

Not always. If your app sells through the App Store and Google Play, the store runs the trial and the payment, and your app reads the status. If you sell on the web with Stripe, the card or no card choice in this guide applies. Want your trial flow scoped before you build? Book a call. Your MVP on web, iOS and Android, Fixed at $3,460.
