tl;dr
Sync Data re-pulls the latest data from one data source into Klar.
Store Update recalculates your whole store against the current data and settings — this is what makes manual changes appear in your reports.
After a change from a Google Sheet source, do both, in order: Sync Data on the sheet first, then a Store Update.
For any other change, just run a Store Update.
Allow about 30 minutes for the numbers to update.
If you edited something in Klar and your reports still show the old values, you almost always just need to trigger a refresh. The catch: there are two different refresh actions, and using the wrong one is why a change sometimes "doesn't work." This article explains both and shows you which to use.
What is Sync Data?
Sync Data sits on an individual data source (open the data source to find it). It re-pulls the latest data from that specific source into Klar — for example, your latest edits in a connected Google Sheet, or fresh orders from a native integration.
Important: on its own, Sync Data does not recalculate the rest of your store. It refreshes what the source delivers, nothing more.
What is a Store Update?
A Store Update recalculates your entire store against the current data and configuration. This is the step that actually flows manual changes — costs, margins, channel rules — into your Profitability, Revenue and marketing reports.
You trigger it under Store Configurator → Store Settings → Update Store Data.
Without a manual trigger, Store Updates run automatically only every few hours. So when you want to see a change now, a manual Store Update is the fastest route.
Which one do I need?
First, check where the changed data came from, then follow the matching path.
The data comes from a Google Sheet source
Sheet-based sources include COGS, Custom Costs, Custom Revenue, CMC, PPS, Influencers, PLC, Targets, Amazon Tax, and Bundles.
Open that data source and click Sync Data to pull your latest sheet edits into Klar.
Then trigger a Store Update via Store Configurator → Store Settings → Update Store Data.
Allow about 30 minutes for the updated values to appear.
The data comes from any other source
For changes that aren't sheet-based — for example configuration changes in the Store Configurator, or data from a native integration — just trigger a Store Update (Store Configurator → Store Settings → Update Store Data) and allow about 30 minutes.
Why using the wrong one fails
The most common mistake is clicking Sync Data after editing costs or settings and expecting the reports to change. They won't — Sync Data doesn't recompute manual changes. You still need the Store Update to recalculate the store. For sheet edits you need both, because the sheet has to be pulled in before the store recalculates against it.
Still not showing?
If your values are still wrong more than ~30 minutes after a Store Update (and, for sheet data, a prior Sync Data), reach out to us — we'll check the reporting.
