Can I see several stores added up?

Yes, on Pro and Scale, if the stores sell in the same currency. Select them in the store menu, and the Overview, the P&L and Inventory add them up. Every line is the sum of the stores' own lines. Every percentage is worked out from those sums, not averaged. So a small store cannot pull the margin as much as a big one.

Pro lets you connect up to 5 stores, and Scale up to 10 stores. The store menu sits at the bottom of the sidebar and lists every connected store. Click a store to select it, and click it again to take it out. The selected stores are highlighted, and the last one always stays selected. A store in another currency opens on its own instead, because a total in two currencies would mean nothing.

On the P&L, the By store view puts one column per store beside their total. In the Daily, Weekly, Monthly and Yearly views, Split by store adds a small row for each store under every line. Inventory lists the stores' products side by side, with a Store column. On the Overview, the card Stores in this view shows each store's profit today, its month so far and its EBITDA margin. Sync now syncs every store in the view.

Each store keeps its own clock. A combined 1 September adds up each store's own 1 September. Today is the earliest of the stores' todays, so yesterday is a full day in every store. The Overview says so when the dates differ. The Forecast, Insights, the cost pages and Settings work on one store at a time. Their header shows which store, with a picker to switch. Margin target chips are hidden while stores are added up.
