Which marketplaces are supported?
All marketplaces your Seller Central account covers – North America (US, CA, MX), Europe (DE, FR, IT, ES, GB and the rest), and beyond (JP, AU, …). Filter any function with the marketplace parameter using country codes.
How fresh is the data?
Function results refresh roughly hourly. Underlying data arrives from Amazon on Amazon's schedule – most reports are near-real-time to a few hours, finance data settles later (that is Amazon, not us).
Do I need one formula per product?
No – and please don't. One call like =DRAGON_INVENTORY("youraccount") returns all SKUs as rows. Filtering per-SKU in separate calls is slower and burns Google's recalculation quota.
Can I use several stores in one sheet?
Yes. The account parameter selects the store per formula, so different formulas can pull from different connected stores.
What's the difference between the Sheets add-on and the dashboard?
Same data, different jobs. Sheets is for your own models – forecasts, reorder plans, whatever you build. The SellerDragon dashboard is the ready-made control panel: PPC management, profit views, restock alerts.
What does it cost?
Plans and current beta conditions are on the SellerDragon site – the help center stays out of the pricing business.
