# Set up your business, locations and taxes
> The structural setup an account needs before anything is imported into it — your business details, currency and formats, every location you sell from, and your tax rates.
Part of step 3 of the [launch path](/docs/guides/launch/overview), [Set up your business](/docs/guides/launch/set-up-the-foundation). Four Settings views, in the order below. Everything you import afterwards attaches to what you set here — stock lives in a location, a price is taxed at a rate, and an order is timestamped in a location's timezone.
**Currency and tax calculation are effectively one-way.** Nothing in the admin blocks you from changing either one later, and that is the problem: neither change converts the prices you have already entered. A listing priced at 120 stays the number 120 — it just means something different afterwards.
Settle both before you enter a single price. After that, changing them is a repricing project, not a setting.
## Do it in this order
| Settings view | What to set | What it affects |
| ------------------------------ | -------------------------------------------------------------------------- | -------------------------------------------------- |
| **Settings → Account details** | Legal name, business ID, address, contact details | Checkout, receipts, finance report headers |
| **Settings → General** | Currency, date and time formats, first day of week, account timezone, logo | Every price and date shown anywhere |
| **Settings → Locations** | One location per place you sell or fulfill from, with hours | What customers can order, and where stock can live |
| **Settings → Taxes** | Your rates, and whether prices include tax | Every price, every order total, every receipt |
Locations come after General because a location inherits nothing useful from an unset account — and before Taxes only because you will want the locations to exist when you sanity-check a price.
## Your business details
**Settings → Account details.** These are public: they appear at checkout, on customer receipts, and in the header of Revenue and Payments report exports.
Three cards:
* **Entity** — **Business name** and **Business ID**. The business name is also the display name on every transactional email you send.
* **Business address** — **Street address**, **ZIP / Postal code**, **City**, **Country**. Leave the whole address blank and it is stored as nothing rather than as empty lines, so a partially-filled address is worse than none: fill in at least the street address if you want it on finance exports at all.
* **Contact information** — **Email** and **Phone number**.
The **Email** here is not the address your transactional email is sent *from*. TWICE sends from its own address, with your business name as the display name. The address you set here is where a customer's reply lands, so use one somebody reads.
This is your **business** account. Your own name, email and interface language are personal settings and live in your [Profile](/docs/settings/profile).
## Currency, formats and timezone
**Settings → General.** Account-wide defaults, applied across the admin and every sales channel.
**Currency** is three fields, not one:
| Field | What it does |
| ---------------------------- | --------------------------------------------------------------------------------------------------------- |
| **Currency** | The currency code. Only currencies with two decimal places are offered |
| **Currency formatting** | Whether prices show the code (`EUR`) or a symbol (`€`) |
| **Currency symbol position** | Symbol before or after the number, with or without a space — `€ 120.00`, `€120.00`, `120.00 €`, `120.00€` |
Currency is one value for the whole account. There is no per-location and no per-channel currency, so an account that genuinely trades in two currencies is two accounts.
**Date and Time** carries four settings: **Date format** (`DD.MM.YYYY`, `MM/DD/YYYY`, `YYYY-MM-DD`), **Time format** (24-hour or AM/PM), **First day of week**, and **Timezone**.
The account **Timezone** is not what your locations inherit. It is used where no location is involved — report exports, account-level jobs. Every location carries its own timezone and defaults to `UTC` until you set it, so setting this one does not save you from setting each location's. See below.
**Logo** takes HEIC, WEBP, SVG, PNG or JPG, and around 512px wide works well. It reaches receipts, documents and the storefront. Storefront colours and fonts are not set here — those live in the [Theme Editor](/docs/sales-channels/online-store/theme-editor/overview), in a later step.
## Every location you sell from
**Settings → Locations.** A location is a place you operate from: a shop, a warehouse, a service point, a venue. Create one for every place stock can sit or an order can be handed over — including the warehouse no customer ever visits, because stock has to belong somewhere.
**A new location is created switched off, with every fulfillment method off.** It is not a half-configured location, it is an inactive one: it does not appear on the storefront, its **Sales channels** card is disabled until you activate it, and none of **In-store pickup**, **Shipping** or **Local delivery** is enabled for any purchase type.
A location that exists but was never activated is the single most common reason a launch-day storefront shows nothing available.
Work each location's tabs through in this order:
| Tab | What to set | Why it matters at launch |
| ----------------------- | ---------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------- |
| **Contact information** | Name, public name, address, email, phone | The public name is what customers see; the internal name is what your staff filter by |
| **Time zone** | This location's timezone | Order times, availability and subscription billing are evaluated here. It defaults to `UTC` |
| **Opening hours** | Weekly hours, seasonal hours, exception dates | A new location defaults to open 00:00–23:59 every day |
| **Fulfillment** | **Order fulfillment** and **Order returns** on, then the methods per purchase type | All methods start off. Nothing can be handed over until you turn one on |
| **Sales channels** | **Online store** on, for locations customers pick | Requires the location to be active first |
| **Overrides** | Location-specific order numbering, if you want it | Optional. Skip it unless you already know you need per-location references |
**One location is the default.** The first one created for an account is marked **Default location**, and TWICE uses it whenever nothing else names a location. It cannot be archived, so if the default is a placeholder from account creation, move the default to a real location before you tidy up.
Auto-assignment is a different switch. **Use auto assign**, on the Fulfillment tab, decides whether stock items are picked automatically when an order is fulfilled or scanned there — it has nothing to do with which location is the default.
### Opening hours versus fulfillment hours
Two schedules, and conflating them is what produces a storefront offering pickup at three in the morning.
**Opening hours** say when the location is open. Three tiers, all on one tab: regular weekly **Opening hours**, **Seasonal opening hours** for date ranges that override them, and **Exception dates** for single days — a public holiday, a stocktake.
**Pickup hours** and **Return hours**, on the Fulfillment tab, say when customers can actually collect and bring things back. Each is set independently, in one of three modes:
| Mode | Use it when |
| ----------------------------- | ------------------------------------------------------------------------------------------------------------------------- |
| **Same as opening hours** | Handover happens whenever you are open. The default, and right for most locations |
| **Offset from opening hours** | You need a buffer — **Starts after opening**, **Ends before closing** — so nobody collects in the first or last half hour |
| **Custom hours** | Handover runs on its own schedule, with its own weekly, seasonal and exception rows |
Offset mode inherits your seasonal hours and exception dates automatically; custom mode does not, so a custom schedule needs its own holiday closures. If a buffer is longer than your shortest open day, the admin warns you and that day becomes unavailable.
Only **In-store pickup** and **In-store return** are live today. **Shipping** and **Local delivery** appear on the Fulfillment tab marked as coming soon — plan your launch around handover at a location.
## Taxes
**Settings → Taxes.** Two decisions, and the first one is the expensive one.
**Tax calculation** is an account-wide choice between **Include tax in price** — the prices you enter already contain tax — and **Exclude tax from price**, where tax is added at checkout. It sets how every price displays and totals, everywhere, and it has no per-location or per-channel override.
Get it right before you price anything. Switching it later does not adjust a single stored price; it changes what those prices mean, so a catalog priced tax-inclusive becomes a catalog priced tax-exclusive at the same numbers, and every total moves.
**Tax rates** are named rates with a percentage — a **Label** like `VAT 25.5%`, an optional **Description**, and the rate itself. One is marked **Set as default for new products**, and that is the rate a new listing picks up.
Three things to know before you create them:
* **Keep exactly one default.** Nothing stops you marking a second rate as default, and every rate carrying the mark is treated as one. Which rate a new listing then picks up is not a decision you made.
* **Rates are account-wide.** The rates table has a **Location overrides** column, but there is no way to set an override in the admin today. A rate is chosen per listing, on the listing itself — plan around that, not around per-location rates.
* **Deleting a rate does not ask what is using it.** The confirmation warns that listings on that rate will be left with no tax rate, and it cannot be undone. During a launch, delete the rates you will not use *before* you build the catalog, not after.
There are no postcode, category or per-customer tax rules. If your tax situation needs them, raise it with your TWICE contact before you price.
## Done when
* **Settings → Account details** shows your legal name, business ID and address, and a receipt rendered from a test order carries them.
* Currency, formats and the account timezone are set, and you have accepted that the currency is now fixed.
* Every place you sell or fulfill from exists as a location, is **active**, and has its own timezone — not `UTC` by default.
* Each active location has real opening hours, not 00:00–23:59, and pickup and return hours that match how you actually hand things over.
* **Online store** is on for every location customers are allowed to choose, and off for the warehouses they are not.
* One location, and one only, is marked **Default location**, and it is a real place.
* **Tax calculation** is set the way your accountant expects, and exactly one tax rate carries the **Default** chip.
* Nothing has been imported yet.
