# Sell a subscription
> Create a monthly plan with a free trial, share it, take your first subscriber, change their plan, and cancel. All from the dashboard, in test mode.
This guide takes you from no plan to a running subscription in the dashboard. You create a monthly plan with a 14-day free trial, pay for it yourself as a test buyer, then move the subscriber to another plan and cancel. Everything runs in **Test mode**, so no real money moves.
How subscriptions behave over their life, and the same actions from code, are on the [Subscriptions](/payments/subscriptions) page.
## Before you start
* An AgentaOS account. The dashboard opens in **Test mode**. You only need to verify your business to take real money: see [Go live](/guides/go-live).
* A second browser, or a private window, to act as the buyer.
* The test card `4242 4242 4242 4242`, with any future expiry date and any CVC. Type it only into the card form on the checkout page.
## Create the plan
In the sidebar, click **Products**, then click **New product**.
Under **Details**, type a **Product name**, for example `Pro`. Buyers see the name and the description on the checkout.
Under **Pricing**, type the price, for example `29`, and pick **EUR** or **USD**. Click **Subscription**, then **Monthly**.
In **Free trial (days)**, type `14`. Leave **Trial price** empty for a free trial.
Click **Create product**. The next screen says "Pro is live". Live here is the product's word for published. You are still in test mode.
Click **View product** to open the plan's page.
## Share the link or embed it
Click **Copy link** and send the link to a buyer: in an email, on your pricing page, or in a post. One link works for every buyer.
To show the checkout on your own site instead, open **Building this into your site?** on the plan's page. Under **Embed on your site**, click **Copy snippet** and paste it into your page. The snippet works only on sites you approve under **Settings → Developers → Approved sites**. See [Embedded checkout](/payments/embedded-checkout).
## Take the first subscriber
Open the link in your second browser and pay as the buyer.
Type an email such as `buyer@example.com` and pick a **Country**. The checkout shows **Due today** €0.00 and the monthly price after the trial, with any VAT for that country.
The 24% is the Estonian rate. The checkout charges it to every EU consumer while AgentaOS sells under the EU distance-selling threshold. See [How tax works](/mor/tax#the-rate-on-eu-sales-today).
Click **Continue to payment**.
Type `4242 4242 4242 4242` in **Card number**, any future date in **Expiration date**, and any three digits in **Security code**.
Click **Start 14-day free trial**. The checkout confirms "Trial started" and €0.00 due today.
The buyer and you each get an email that the trial started. The first charge happens on the day the trial ends.
## See the subscriber
In the sidebar, click **Subscriptions**. The new subscriber shows with the status **Trialing** and the date of the first charge under **Renews**.
The price in the list includes any VAT the buyer pays, so it can be higher than the plan price. Click the subscriber's name to open the subscription.
## Change their plan
A plan change needs a second plan in the same currency and with the same interval. Create a product named `Pro Plus` at `49`, **Subscription**, **Monthly**, the same way as above.
On the subscription page, click **Change plan**.
Pick **Pro Plus** from the list. The dialog shows what is due today and the price from the next renewal.
Click **Confirm change**. An upgrade applies at once, so the subscription now shows Pro Plus.
A move to a cheaper plan waits for the end of the period. The dialog says "No charge today" and the date the change takes effect.
After you confirm a downgrade, the subscription shows **Scheduled change** with the new plan and its start date. To drop the scheduled change, click **Change plan** again and pick the plan marked "current plan".
## Cancel
On the subscription page, click **Cancel subscription**.
Read the dialog, then click **Cancel subscription** again.
The status changes to **Cancels** followed by the end date. The subscriber keeps access until then, and nothing more is charged. To keep them after all, click **Resume subscription** before that date.
## From code: subscribe a signed-in user
When the buyer already has an account in your app, create the checkout from your server with the plan's link ID and your own user ID in `metadata`. Use these pages:
* [Subscriptions in the SDK](/sdk/pay-subscriptions): the checkout call for a signed-in user, and how to match renewals to your user.
* [Paywall for logged-in users](/sdk/paywall-for-logged-in-users): the complete integration, as a runnable demo app with the user's invoices and plan management.
* [Subscriptions](/payments/subscriptions#from-code): creating plans, listing subscriptions, plan changes, and canceling from code.
