# Configure settings
> Work through every settings view in order, and know which ones cannot be corrected later.
Step 2 of [migrating from TWICE 1.0](/docs/guides/migration/overview). Work through Settings in the order below — the order they appear in the product. Open every view, including the ones you expect to skip.
Currency, timezone and tax settings apply to every order and cannot be corrected retrospectively. A receipt already issued keeps the tax it was issued with. Set these before any order exists.
## Organization
| Settings view | What to set | What it affects |
| --------------- | -------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------- |
| Account details | Entity, business address, contact information. | Prints on receipts, documents and finance exports. |
| General | Currency, formatting, timezone, logo. | Every order. Set before any order exists. |
| Locations | Contact and address, cost center, opening hours, sales channels, fulfilment and return methods and hours, order numbering. | What can be sold where, which location an order is assigned to, and the hours customers can collect and return. |
| Users & Roles | Users, system roles, custom roles. | Who can do what. See step 6. |
| Security | Sign-in methods, security restriction bypass. | How your team signs in. |
| Subscription | See step 4. | Your plan and billing. |
| Taxes | Tax rates and settings. | Tax on every order. A later change does not correct receipts already issued. |
Decide explicitly whether your prices include or exclude tax, and tell your bookkeeper what order numbering you chose. Both are hard to change once you are trading.
## Storefront and operations
| Settings view | What to set | What it affects |

| Orders | Order states and fulfilment states. | How an order moves through your process. |
## Content
| Settings view | What to set | What it affects |
| ------------------------ | ------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------- |
| Terms & Policies | Create a policy, status and preview, where policies appear. | What customers accept at checkout. Can also appear in your store footer. |
| Documents | Templates, content, translations, defaults and visibility. | Internal and external documents — agreements, usage instructions, receipts. |
| Emails | System and custom templates, translations, attachments, test sends and status. | Order confirmations and team notifications. |
| Translations & Languages | Supported languages, coverage, translation editor, system wording overrides. | Customer-facing wording in every language you sell in. |
| Listing templates | What a template is, create and edit, using one. | Speed of creating listings. Not required to trade. |
| File Manager | Upload, organise and find files. | Images and files used by listings, emails and documents. |
| Attributes & Tags | Attributes, attribute groups, tags. | The custom fields that model your inventory, catalog, orders and customers. |
| Archived assets | Browse by type, unarchive, delete. | Where archived listings and stock items sit. Should be empty now; use it to archive test orders before you go live. |
**Read the wording of every customer-facing email and document out loud before you approve it.** These are the parts of TWICE your customers actually see, and migrated defaults are rarely what you would write.
