Free trial

What is a free trial?

A free trial is a set period, often 7, 14 or 30 days, when a buyer can use your product for free before they decide to pay. Most trials give access to a paid plan, so the buyer sees what they'd actually get.

Let's say you sell invoicing software to agencies. A studio owner signs up, connects their bank, adds two clients and sends a first invoice on day two. By day ten, one client has paid through the invoice link. When the trial ends, she already knows the tool works for her business, so paying feels like a small step.

A trial is one of the main ways product-led growth companies let the product do part of the selling. The other is a freemium plan, which never runs out.

Why free trials matter for B2B SaaS

B2B buyers want proof before they sign. According to Forrester's State of Business Buying 2026, more than 60% of business buyers use a trial before they buy, and for purchases of $10 million or more, it's 78%.

That means a trial is often part of the deal even when sales runs the process. A buyer who has used the product has fewer doubts on the call, and the deal moves faster.

Here's why I think most B2B SaaS teams should offer one:

• It answers "will this work for us?": No sales deck beats a buyer seeing their own data in your product. The trial turns your claims into something they can check.
• It cuts the sales cycle: Buyers who've tested the product skip a round of demos and questions. That shortens the sales cycle, especially for smaller deals.
• It shows you who's serious: Trial activity tells sales which accounts to call. A team that invited five coworkers on day three deserves a call before one that signed up and left.

How to set up a free trial

A trial works when the buyer reaches a real result before it ends. Here's my process:

• Define the first useful result: Pick the one action that shows the product working, like sending a first invoice or running a first test. Everything in the trial should push toward it.
• Pick the length from that result: If a normal buyer can get there in three days, 14 days is plenty. If setup needs IT and data imports, 30 days may be fair.
• Decide on the credit card: In ChartMogul's 2026 report, trials that ask for a card convert 30% of users to paid, more than 5 times the rate without one. Only 20% of trial products ask for one, though, since a card at sign-up means fewer people start a trial at all.
• Cut setup steps: Pre-fill sample settings, offer imports from the tools buyers use today and skip any field you don't need on day one. Every extra step loses people.
• Send emails based on what people do: Email the person who hasn't connected their data yet, and send a different email to the one who already has. Generic day-3 and day-7 emails get ignored.
• Bring in sales at the right moment: For larger accounts, a short call when a trial team hits a usage signal often closes the deal. Let small buyers pay on their own.

Free trial examples

Two well-known B2B tools show how different a trial can look:

• Zendesk: The customer service platform offers a 14-day free trial with no credit card required. Support teams can set up a help desk and answer real tickets before anyone talks to sales.
• Salesforce: Salesforce offers a 30-day free trial of its Enterprise Edition. The longer window fits a CRM, where a team has to import data and set up its sales process before it can judge the tool.

Here's how a hypothetical invoicing software company might plan its 14-day trial:

How to measure a free trial

Count sign-ups, but judge the trial by what happens after. Here's what I'd track:

• Trial-to-paid conversion: The share of trial users who become paying customers. ChartMogul counts 4% to 6% as good for trials without a card, so compare yourself with the right group.
• Time to first result: How long it takes a new user to reach the first useful result. Pull it from your product analytics, and work to shorten it every quarter.
• Activation rate: The share of trial users who reach that result at all. A low number points to setup steps that need fixing.
• Trial sign-ups by source: In GA4 and your CRM, check which pages and channels bring trials that convert. A comparison page might bring fewer sign-ups but better ones.
• Cost per paying customer: Divide what you spend to get trial sign-ups by the paying customers they turn into. That's the number that feeds your CAC.

Common free trial mistakes

• Leaving buyers alone: A trial without guidance often ends with an account nobody touched. Show the next step inside the product and by email.
• Making the trial too long: A 30-day trial for a tool that takes 10 minutes to set up gives buyers time to forget about it. Match the length to the setup.
• Hiding the paid plans: If buyers don't know what the product costs, the end of the trial feels like a trap. Link the pricing page from inside the trial.
• Counting sign-ups as success: A jump in trials from a broad ad can bring people who were never going to pay. Judge each channel by paid conversions.
• Ignoring the people who leave: Ask trial users who don't convert one short question about why. Their answers point to the step to fix next.
