Switching between
locations.

How the location picker changes every tab below it — and why two locations never bleed into each other's numbers.

Top-right, every page. The location picker is in the header on every authed tab. Whatever you pick scopes everything below it — Home, P&L, Revenue, the lot.

If you run multiple shops, the location picker is the most important control in nouz. It's the single switch that determines which shop's data you're looking at on every tab. Get used to glancing at it whenever you open Home — especially first thing in the morning when you're still half asleep.

01 Where do I find the location picker?

Look at the top-right of Home. The location picker is a button showing the current shop's name with a small downward caret. Click it for a dropdown of every location you've created on your business — pick one, the picker closes, and the page reloads scoped to the new shop. It lives in the same top-right spot on every authed tab, and on mobile it collapses more compactly but works the same way.

On mobile, the picker collapses into the header more compactly but works the same way. On every tab — Home, Revenue, Expenses, Products, Fixed Costs, P&L, Statistics — it lives in the same place.

02 What does the picker actually scope?

Picking a location changes the data shown on every tab below it. Home shows that shop's today tile, week-so-far, and sentence; Revenue and Expenses show only that location's entries; Products and Fixed Costs show only its catalogue; the P&L recomputes all four views (day, week, month, year) against its data; and Statistics shows single-location insights, charts, and ranking. Nothing from another location bleeds in. The list below breaks it down tab by tab.

  • Home — today's tile, week-so-far, sentence — all per-location.
  • Revenue / Expenses — entries shown belong only to the active location.
  • Products / Fixed Costs — only the active location's catalogue.
  • P&L — all four views (day / week / month / year) recompute against the active location's data.
  • Statistics — insights, charts, ranking, all single-location.

03 Does nouz remember which location I picked?

Yes. Your last-picked location is stored in a cookie and localStorage, so closing the tab and coming back later drops you straight back on the same shop. Switching device — phone versus desktop — defaults you to your first location, then remembers your pick on that device too. If you delete or archive your last-picked location, the next page load drops you on your first available one, so you never end up on a "no location" screen.

If you delete your last-picked location (or it gets archived), the next page load drops you on your first available location instead. You'll never end up on a "no location" screen.

04 Is the location separation enforced on the server?

The picker is a real boundary. Every database query in nouz checks the active location_id server-side. There's no way to accidentally see another location's data, even if you tried to forge the request — the middleware rejects it.

Yes — the picker is a real boundary, not just a UI filter. The active location is passed into every server query as a filter, and the middleware independently verifies you have access to that location before returning any data. So even if a bug in the UI sent the wrong location_id, the server would reject it rather than silently return the wrong shop's revenue. There's no way to accidentally see another location's numbers.
