# Connect payments

> Connect your payment account early, and prove a live payment before you switch.

Step 3 of [migrating from TWICE 1.0](/docs/guides/migration/overview). **Start this first**, out of order if you need to. If you are applying for a new payment account, the verification is outside your control and it is the single item most likely to move your switch date.

## Connect the account

Connect card payments under **Settings → Payments**. Connect your existing Stripe account, or create a new one at stripe.com.

Add offline methods if you accept them — pay on collection, invoice, and so on. These appear at checkout but are handled and reconciled manually.

<Warning>
  Your 1.0 payment connection does not carry over, and deposits held in 1.0 stay in 1.0. You release them from the 1.0 order, not from 2.0 — see [step 9](/docs/guides/migration/run-both-systems-down).
</Warning>

## Prove a live payment before you switch

Take a payment on a real card in **live mode**, then refund it.

A test-mode payment proves the integration is wired up. It does not prove your account is verified, that payouts will arrive, or that the money reaches the right bank account. Only a real transaction does that, and it is cheap to run.

Do the same for deposits if you take them: place a hold on a real card and release it.

## Done when

* Payments are connected and verification is complete.
* Every payment method you use is enabled and appears at checkout.
* Deposits are configured on the checkouts that take them, and a hold and a release have been tested.
* A live-mode payment has been taken and refunded.
* You know which 1.0 deposits are still open and where to release them.
