# Go live

> The pre-launch check, the domain switch, the first real order, and closing the old system's intake.

Step 10 of the [launch path](/docs/guides/launch/overview). Two parts: a check that answers go or no-go, and then the switch itself.

Run the check about two weeks before the date, not the day before. Its whole value is that there is still time to fix what it finds. No-go is a normal, cheap outcome at that distance and an expensive one on the morning of.

## Run the pre-launch check

Walk this list and answer each one honestly. Anything you cannot answer yes to is either fixed before the date, or the date moves.

1. Steps 2 to 9 are finished — payments, your business, data, catalog, storefront, external dependencies, testing and training.
2. A real payment has gone through on live settings, not test ones, and the money arrived.
3. Your imported data has been checked against the source **by value**, not just by row count.
4. Staff have been trained and can each do their own job unaided.
5. You have written down what would make you roll back, and who decides.
6. Someone specific is on call for the first week, and your team knows who.

**Done when:** every point is a yes, or the date has moved.

## Switch over and verify

The switch itself is small: make your domain primary, confirm the payment methods a real customer sees are the live ones, and confirm everything meant to be on sale is visible.

Then watch the **first genuine order** all the way through rather than waiting for a customer to find the problem — it appears in the admin, the stock is reserved, the confirmation arrives, the payment settles.

  A guide for switching over and verifying your first real order is in progress. Until it lands: [Domains](/docs/settings/domains), [Set up the online store](/docs/guides/sales-channels/set-up-the-online-store), [Where a listing sells](/docs/guides/sales-channels/control-where-a-listing-sells), [Take payment](/docs/guides/orders/take-payment).
</Note>

**Done when:** your domain resolves to TWICE and the first real order is correct in every detail.

## Close the old system's intake

Stop the old system taking new bookings on the day you switch, and keep it **readable** until the last rental and deposit it holds has cleared — which for long hires can be months. Two systems both accepting orders is how you get double-booked.

See [Archive stock items](/docs/guides/inventory/archive-stock-items) and [archiving and deletion](/docs/concepts/repeating-patterns/archiving-and-deletion).

**Done when:** new bookings can only be made in TWICE, and the old system is still readable for what it holds.
