When your free Asana trial expires, you'll be shown a popup message which prompts you to choose the right plan for your team. You can seamlessly upgrade to a Starter or Advanced plan by clicking Select your plan to avoid interruption to your work.
On the next page, you can purchase an Asana Starter or Advanced plan directly, but if you'd prefer to explore Enterprise or Enterprise+, click Contact us to talk to our sales team.

Choose your preferred plan, and then add your payment details. Check out our step-by-step guide on how to add payment details, as well as edit your chosen plan's details before you purchase.
It's important to note that upgrading to a paid plan will not result in any data loss. Even if your trial comes to an end, all your existing rules, workflows, and portfolios will remain intact, allowing you to continue working without disruption when you're ready to upgrade.
