How to upgrade your plan and manage billing in Thinkr

Thinkr has four tiers: a Free trial, Solo and Team (both self-serve), and Enterprise (a conversation with us). Solo and Team you can pick and pay for yourself in a couple of clicks, and you manage everything afterwards from the same place. Payments are handled by Lemon Squeezy as the merchant of record, so your invoice, receipt, and any tax are taken care of for you.

Before you start

Billing is per workspace. If you belong to more than one, switch to the workspace you want to upgrade first (the switcher is in the sidebar), so the subscription attaches to the right one.

Step 1, Open Plans & Billing

Go to Settings → Plans & Billing. At the top you'll see your current plan, your usage this period, and, if you're on a trial, how many days are left. Below that is the Available plans grid.

Step 2, Pick a plan and interval

Use the Monthly / Annual toggle to choose your cadence (annual saves roughly two months). Then click Upgrade to Solo or Upgrade to Team on the plan you want.

You'll be taken to a secure Lemon Squeezy checkout to enter your payment details. When the payment goes through, you're redirected back to Thinkr and your new plan activates right away, the higher usage limits and features unlock immediately.

Step 3, Manage your subscription

Once you're on a paid plan, a Manage subscription button appears next to your plan in the Current plan section. It opens the Lemon Squeezy customer portal, where you can:

• Update your card or payment method.
• Switch between monthly and annual.
• Download every invoice and receipt (handy for expenses, the merchant of record details and any tax are already on them).
• Cancel the subscription.

Step 4, Cancelling

If you cancel, you keep full access until the end of the period you've already paid for, nothing is cut off mid-cycle. After that the workspace returns to the Free tier: your existing PRDs, notebooks, proposals, prototypes, and critiques stay visible, and new generations resume when you pick a paid plan again.

A note on receipts and tax

Because Lemon Squeezy is the merchant of record, they issue the invoice and receipt and handle sales tax or VAT, you don't need to request anything from us. Everything is downloadable from the Manage subscription portal at any time.

Need Enterprise?

Larger teams with custom needs (uncapped seats, procurement, security review) are on a custom plan. Use the Contact sales option on the plans page and we'll take it from there.
