SUT·LER
A converted file is a snapshot. An import is a working purchase-order history.
Credit where it is due
EZStock was built for the Stocky shutdown by an independent developer, and its free Stocky Export Converter is a genuinely useful tool: it runs in your browser, it asks for nothing — no email, no account — and it converts your Stocky CSV exports (and the richer API JSON) into a Shopify-native CSV and an EZStock-ready file. If all you need is the conversion, it does the conversion. This page exists for the step after that.
The step after the conversion
A converted file is portable — that is its virtue and its limit. The Shopify CSV the converter hands you lands in your store as products, inventory, and draft purchase orders. What it does not become is a purchasing system: there is no receiving desk to receive against those orders, no landed-cost history carried as live records, no stocktake continuity — because a file is not a desk, in EZStock's funnel or anyone's. The conversion is where their tool ends. It is where Sutler begins.

Which one you need
If your Stocky data is small, your ordering is occasional, and a converted file plus Shopify's native drafts covers your desk, EZStock's converter may be all you ever need — it costs nothing and it respects your data. If you order every week, receive partial shipments, split freight across lines, and need your Stocky cost history to keep working as live purchase orders rather than sit in a spreadsheet, that is the job Sutler imports into. Run the free Checker first either way: knowing exactly what your export contains makes both tools work better.
Check your Stocky export first — it takes two minutes and nothing uploads.
The free Stocky Export Checker reads your Stocky files in your browser and counts what is actually inside them: the suppliers, products, and open purchase orders that will carry over — and what won't. Supplier records don't export from Stocky at all; the names only survive on your PO rows, and a partial-range export silently truncates your cost history. Export access is guaranteed through at least Nov 29, 2026, so there is still time to pull a full-range copy and verify it.
What Sutler does and doesn't do
What Sutler does and doesn't do: Sutler suggests what to reorder from your sales, lead times and minimums, with the math shown, but it makes no promise about forecast accuracy. It does not do transfers between locations: if that is the job you need done, Sutler is the wrong tool and you should know that before you install anything. What it does is the purchasing desk: purchase orders, receiving, labels, stocktakes, landed cost, invoice capture — and it imports your Stocky export into working purchase orders.
Sutler is in early access and not yet on the Shopify App Store. EZStock figures from EZStock's public pages, checked November 2026; if their pricing or plans change, this page will be corrected.
