Work the steps in this order, starting with Before you start. Every later step depends on the six decisions it asks for. Start Connect payments early, then carry on down the list without waiting for it to finish. Settle locations, taxes and attributes before you import anything. They sit underneath everything after them and are expensive to change once data exists. Follow Migrating from TWICE 1.0 instead if you are moving from 1.0 rather than starting fresh. That path covers the same ground with a live system on the other side of it. Ask your TWICE contact which steps they run for you if you are launching on a Custom or Enterprise package. The path is the same either way, so it doubles as the list of what has been done on your behalf. Open Working in TWICE in the sidebar for the full detail on any one area, and for the day-to-day tasks that come after 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.

Connect payments

Done when: payments are connected, verification is complete, and a checkout is attached to the channel that uses it.

Set up your business

Done when: your details, locations, taxes, attributes, users and paperwork are in place. Nothing is imported before this is true.

Bring in your data

Done when: your stock is in TWICE and the count matches what you exported.

Build your catalog

Done when: a listing shows correct availability for a real date.

Design your storefront

Done when: the storefront looks like you and reads in your customers’ language. Never hold a launch for this step.

Clear external dependencies

Done when: your domain is verified, integrations are tested, and every old link you published has an owner.

Test your processes

Done when: your own people have run every case unaided and seen the customer-facing output.

Train your team

Done when: each person can do their own job in the admin without help.

Go live

Done when: the domain is primary, the first real order is verified, and the old intake is closed.

Your first weeks

Done when: you can read your own numbers and know where to go when something looks wrong.
