If you run a B2B SaaS trial, asking for a card at signup will usually raise your free-to-paid conversion rate and shrink your signups. Whether that raises your paying customers depends on your traffic, your price and how fast your product shows its first result. This guide gives you the numbers, the trade-offs and a way to decide.
If you landed here looking for a test card number or a virtual card to try a trial without being billed, that is a different job. Developer sandboxes publish test numbers for checkout integrations, and those numbers only work in test mode. This article is for the team on the other side of the form: the one deciding whether to ask for a card at all.
TL;DR
- Card-required trials convert far better per signup: ChartMogul reported 30% for them, against an 8% median across all products it studied.
- They also bring in fewer signups, so compare paying customers per 1,000 visitors, never conversion rate alone.
- Part of a card-required conversion is inertia. Expect refunds, disputes and first-invoice cancellations to show up a month later.
- Whichever you choose, a trial that does not deliver a first result quickly will convert poorly. Fix the path to value first.
- If you take a card, disclose the billing terms before you collect it. Federal and state law already cares about how you do this.

What the data says about cards and conversion
Start with how common each approach is. ChartMogul's February 2026 report, covering 200 B2B software products, found that 20% of free-trial products asked for a card upfront and 80% did not. The most common trial length was 14 days. Separately, SaaStr's summary of Tomasz Tunguz's research noted that only 12 of 600 companies required payment details at trial start, and that requiring them more than doubled conversion.
The gap per signup is large. In ChartMogul's data, card-required trials converted at 30%. The report's 2026 benchmark bands, as summarized by a third party, put a "good" result for a no-card trial at 4 to 6% and a good result for a card-required trial at 25 to 35%. Read those as two different games with two different scoreboards.
| Model | Typical conversion (ChartMogul 2026) | Signup volume | Who signs up |
|---|---|---|---|
| Free trial, no card | Median across all products: 8% | Higher | Curious and committed, mixed |
| Free trial, card required | 30% reported | Lower | Self-selected, more intent |
| Freemium | Often lowest per signup | Highest | Includes many who never plan to pay |
The percentages hide the number that pays your bills. ChartMogul's per-1,000-visitor model showed standard trials producing 45 signups and 3.6 paying customers, and card-required trials producing 35 signups and 10.5 paying customers. In that model, the card wall cost you about a fifth of your signups and nearly tripled the paying customers.
One caution before you copy that result. A model is not your funnel. Your price, your buyer and your product determine which side wins, and the real-world tests below do not all agree.
Two real tests, two different outcomes
Outseta's 2025 case study compared freemium at 7.25% conversion with a seven-day card-required trial at 35%, counting a customer only if they were still paying 30 days after converting. The trial generated 43% as many signups as freemium. By their own figures, 100 freemium signups produced about 7 customers, while 43 trial signups produced about 15.
PhoneBurner's account of its experiment went the other way on strategy. Removing the card requirement increased new users by 239%, and conversion fell from 73% among card signups to 22% among no-card signups. The card funnel still produced 35% more paying customers and 16% more revenue in the test. But card-originated customers churned at roughly twice the rate. The team chose the no-card funnel for its larger, more engaged prospect pool.
The lesson is not that one side wins. It is that the winning answer depends on what you are optimizing: this quarter's new customers, or the size and quality of the pool you can nurture over time.

The trade-offs in plain terms
What a card wall buys you
A card filters for intent. People who hand over payment details have already decided your product is worth a serious look, so your sales and lifecycle effort lands on warmer users. It also lets the trial end in an automatic conversion, which is a big reason the rate looks so strong.
What it costs you
That automatic conversion is partly inertia. Dodo Payments describes a share of card-required conversions as people who meant to cancel and never got around to it. They count in your rate on day one and reappear a month later as refund requests, disputes and first-invoice cancellations. A no-card trial has no such default: every conversion is a decision made by someone who has used the product, and those customers tend to renew more, according to the same source.
You also shrink the top of your funnel. For a product whose value shows up in the first session, that can mean fewer people ever see it work.
What a no-card trial costs
The wider funnel is not free. It brings support load, abuse and a longer nurture cycle, and it only converts if you build the onboarding and prompting that moves people to pay. A no-card trial without that work is a leak, not a strategy.
How to decide for your product
Use these criteria in order. Most teams can decide after the first three.
- Price and buying process. Battery Ventures says freemium is typically strongest around $10 to $50 per month, where individuals can self-serve or expense it. Higher-priced, more complex software more often needs sales or implementation support, which suits a trial. The higher your contract value, the more a card-less, human-assisted trial makes sense, because a card at signup can feel odd for a five-figure purchase.
- Who gets the first result. If one person can reach value alone in a single session, a card wall costs you little. If value needs integrations, teammates or data import, asking for a card before any of that happens loses people who would have stayed.
- Traffic source. Paid traffic that you must justify to finance often favors a card wall. Content-led, word-of-mouth or bottom-up traffic often favors a open door.
- Cost of a free user. If each trial user burns real compute, as in many AI products, unlimited no-card signups are a direct expense. Writing about the security side of the choice, one analyst notes that card walls attract stolen-card testing and single-use virtual cards, while open trials invite scraping and credit draining. Plan for the abuse type your choice invites.
- Capacity to nurture. A no-card trial needs lifecycle emails, in-product guidance and a clear upgrade moment. If you have none of that yet, the card wall is doing work your product is not.
A fourth option sits between the two. A reverse trial gives full access first and drops users to a free tier instead of locking them out. We cover how it works in our guide to the reverse trial and when it fits.
Freemium or free trial: which model fits
The core difference is simple. Freemium offers a free tier with a functionality-based paywall and open-ended access. A free trial gives full functionality for a limited time, then asks for payment or stops access, as Craft Ventures explains.
In that firm's 2019 guidance, freemium fits products that spread bottom-up or virally, have network effects or user-generated content, or where free users and buyers have different needs. Free trials fit products provisioned by an admin, products fed by paid marketing, and cases where a deadline creates useful urgency.
In practice, trials dominate B2B. In ChartMogul's sample, 57% of products used a free trial as the main landing point, 26% used freemium and 7% used a reverse trial.
Freemium has real upsides: it can build a large user base and a lasting brand presence. The flip side, per Battery, is that many users stay on the free plan and upgrading is never guaranteed. High serving costs can make it impractical, and complex products usually do better with a trial plus sales or support. If you pick freemium, treat the free plan as a funnel with its own activation targets, not as a parking lot.
Benchmarks that are safe to use
Two cautions keep your benchmarking honest.
First, know how the number was measured. ChartMogul's survey counted leads or free signups that converted to paying customers within six months. Outseta counted customers still paying 30 days after conversion. Your own definition should be written down before you compare yourself to anyone.
Second, split your cohorts. The SaaStr summary described 4% as an unassisted target and 15% as an assisted one, so a blend of self-serve and sales-touched trials will mislead you. Report each separately.
A useful sanity check for the product itself: Userpilot's analysis of 62 B2B companies found an average activation rate of 37.5% and an average time to value of about 1 day, 12 hours and 23 minutes. If your trial users take far longer to reach a first result, the card question is not your biggest problem. We break down how to measure and cut that gap in our time-to-value guide.
Fix the path to value before the card question
A card wall does not fix a trial that fails to deliver a result. It only changes who is around to see the failure. Amplitude's guidance says a trial that is too long delays monetization, while one that is too short may stop users reaching the aha moment. It recommends setting trial length from the usage data of paying customers, and using session recordings and analytics to find friction.
The patterns we look for when we go through a trial as a buyer:
- Setup before the first result. Connecting data, inviting teammates or configuring settings before the user sees anything useful.
- An upgrade prompt that lands too early. A paywall before the first win reads as a tax, not an invitation.
- A late price reveal. If the checkout total appears only at the last step, people feel tricked, especially when a card is already on file.
- No defined activation event. If your team cannot name the one action that predicts payment, you cannot design the first session around it.
For concrete examples, see our onboarding flow examples and the teardowns that show what each reveals. If you are building a repeatable first-week sequence, a set of onboarding workflow templates can give your team a structure to adapt.
Test it properly
You can learn more from an experiment than from any benchmark. Split new traffic between the two versions, hold everything else constant, and wait until you can see paid customers, not just conversions at trial end. Track these for each arm:
- Signups per 1,000 visitors.
- Activation rate, using your defined first-result event.
- Paying customers per 1,000 visitors.
- Refunds, disputes and cancellations within the first 30 to 60 days.
- Retention at month three.
The winner is the arm with more retained paying customers per 1,000 visitors, not the one with the prettier conversion rate. Checkout and form changes belong in the same discipline: testing checkout and forms first keeps you from changing five things at once.
Billing and cancellation: disclose before you collect
If your trial rolls into a paid plan automatically, you are running what US regulators call a negative option, and the way you present billing terms matters.
The FTC finalized its updated Negative Option Rule in 2024. It would have required clear disclosure of material terms before collecting billing information, express informed consent before charging, and a cancellation method as simple as signup. The rule's disclosures included that charges recur or increase after the trial unless the customer cancels, the cancellation deadline, and the amount and frequency of charges. You can read the rule text for the detail.
That rule is not currently in effect. Law-firm analysis from 2026 reports that a federal appeals court vacated it in 2025 on procedural grounds, and that the FTC has kept pursuing negative-option practices under Section 5 of the FTC Act and ROSCA while working to reintroduce a version. So the safe design is the same either way: put the price, the renewal date and the cancellation route in plain view before the card field, and make canceling as easy as signing up. Because state auto-renewal laws also differ, have counsel review your flow before launch.

This is good conversion practice as well as compliance. Clear terms cut the refunds and disputes that inflate card-required conversion numbers.
Our perspective
We rarely start with the card question. We start by going through the trial as a buyer, with a stopwatch and a screenshot of every step, and we write down where the first result arrives. If that takes 40 minutes, the card wall is not your problem. The trial is.
Once the path to value is short, the card decision becomes a business choice, and a fair one either way. A card wall suits products with a high-intent audience and a first result that arrives in one session. A no-card trial suits products with a longer buying process, as long as there is a nurture and upgrade path behind it. What we do not recommend is choosing by benchmark alone, because a 30% rate and an 8% median describe different funnels.
Our work is tying every change to documented user behavior: where people stall, which prompt lands too early, which total shows up too late. Then we show what to fix first and why. That turns the card debate from a guess into a test you can read.

FAQ
Should a B2B SaaS free trial require a credit card?
It depends on your price, your time to first result and your traffic. Card-required trials convert at much higher rates per signup, but you will get fewer signups and some conversions will be inertia. Compare retained paying customers per 1,000 visitors in an A/B test before you decide.
What conversion rate should I expect from a free trial?
ChartMogul's 2026 report found an 8% median across its sample and 30% for card-required trials. Benchmark bands vary by model, and sales-assisted trials run higher than self-serve ones. Define conversion the way you will measure it, then compare only like with like.
Is freemium or a free trial better for a SaaS product?
Freemium tends to fit simple, lower-priced products that spread bottom-up, where a big user base helps. Free trials tend to fit complex or higher-priced software that needs sales or implementation help. Many B2B products use a trial, and a reverse trial blends the two.
Can I use a fake card to get a free trial?
Test card numbers only work in payment sandboxes, not on live checkouts. For a real trial you can use a card from a provider that offers disposable or virtual numbers, but check the service's terms first. As a SaaS owner, expect some signups to use single-use cards that fail at the first real charge.
