# Launch TWICE

> The launch path: nine steps from an empty account to your first weeks live, each one a checklist of guides.

This is the order to do things in. Each step names what to do and how you know it is done; the guides underneath it do the walking through.

Work the steps in order, with one exception: **[Connect payments](/docs/guides/launch/make-it-sellable) is second because it waits on someone else.** Verification is outside your control, and it is the item most likely to move your launch date. Start it, then carry on down the list while it clears.

If you are moving from TWICE 1.0 rather than starting fresh, follow [Migrating from TWICE 1.0](/docs/guides/migration/overview) instead — it covers the same ground with a live system on the other side of it.

Otherwise: The early ones cost nothing to get right and are expensive to change later: locations, taxes and attributes sit underneath everything you import afterwards. The first step is not configuration at all, it is the handful of decisions that set the rest.

If you are launching with us on a Custom or Enterprise package, your TWICE contact runs some of these steps for you and will tell you which. The path is the same either way, so it is also the list of what has been done on your behalf.

  <Card title="Before you start" href="/docs/guides/launch/before-you-start">
    Done when: one person owns the launch, a target date is set, and you know where your data is coming from.
  </Card>

  <Card title="Connect payments" href="/docs/guides/launch/make-it-sellable">
    Done when: payments are connected, verification is complete, and a checkout is attached to the channel that uses it.
  </Card>

  <Card title="Set up your business" href="/docs/guides/launch/set-up-the-foundation">
    Done when: your details, locations, taxes, attributes, users and paperwork are in place. Nothing is imported before this is true.
  </Card>

  <Card title="Bring in your data" href="/docs/guides/launch/bring-in-inventory-and-catalog">
    Done when: your stock is in TWICE and the count matches what you exported.
  </Card>

  <Card title="Build your catalog" href="/docs/guides/launch/build-your-catalog">
    Done when: a listing shows correct availability for a real date.
  </Card>

  <Card title="Design your storefront" href="/docs/guides/launch/shape-the-storefront">
    Done when: the storefront looks like you and reads in your customers' language. Never hold a launch for this step.
  </Card>

  <Card title="Clear external dependencies" href="/docs/guides/launch/clear-external-dependencies">
    Done when: your domain is verified, integrations are tested, and every old link you published has an owner.
  </Card>

  <Card title="Test your processes" href="/docs/guides/launch/test-end-to-end">
    Done when: your own people have run every case unaided and seen the customer-facing output.
  </Card>

  <Card title="Train your team" href="/docs/guides/launch/train-your-staff">
    Done when: each person can do their own job in the admin without help.
  </Card>

  <Card title="Go live" href="/docs/guides/launch/go-live">
    Done when: the domain is primary, the first real order is verified, and the old intake is closed.
  </Card>

  <Card title="Your first weeks" href="/docs/guides/launch/first-weeks-live">
    Done when: you can read your own numbers and know where to go when something looks wrong.
  </Card>

## What this path is not

It is not a reference. Its guides are written for the launch job and stop there — enough to get you live, not everything the product can do. For the full detail on any one area, and for the day-to-day tasks that come after launch, see **Working in TWICE** in the sidebar.

Where a launch guide is still being written, the step says so and points at the reference pages that cover the same ground in the meantime.
