Migrate from Stocky to a new app: the complete checklist

The one deadline that matters

Stocky was pulled from the App Store on February 2, 2026 and fully shuts down on August 31, 2026 — the API dies that day. Shopify then allows roughly 90 days (until about November 30, 2026) of read-only manual UI export, but that window cannot export suppliers and drops PO line items. So the clean, complete export is only possible while the API is alive. Everything below is ordered around that.

Phase 1 — rescue your data (do this first, this week)

• Confirm API access. Open Stocky → Preferences → API and check you can see a key. If not, ask Shopify support to enable it now — not on August 30.
• Export everything. Pull suppliers, purchase orders (with line items), stock adjustments and tax types. The free exporter does this in one pass; or call the read-only v2 API yourself and map the JSON to CSV.
• Keep the raw JSON too. A lossless raw.json backup protects you against any field a CSV mapping might not capture.
• Note what the API can't export. Lead times, MOQs, case packs, reorder rules and forecasting settings are UI-only. Screenshot or write these down before the shutdown.

Phase 2 — pick where you are going

• Native Shopify admin (free). Now has purchase orders, transfers and Sidekick reorder suggestions, but still lacks lead-time / MOQ tracking, restock-to-target, and keeps only 180 days of inventory history. Fine for very simple shops.
• A spreadsheet. The most common stopgap. Your exported CSVs drop straight in.
• A paid replacement app. Compare on price model (flat vs revenue-tiered vs per-SKU), whether it does purchase orders and receiving, and — critically — whether it can import your supplier data. Most cannot, which is why the export matters.

Phase 3 — move in without re-keying

• Import suppliers first. This is the highest re-keying cost. If your new tool imports suppliers.csv, use it; if not, that is a strong signal it is the wrong tool.
• Load PO and cost history. Bring in purchase_orders.csv and po_line_items.csv so vendor spend and cost history survive.
• Rebuild the UI-only settings. Re-enter the lead times, MOQs and reorder rules you noted in Phase 1.
• Verify against the raw backup. Spot-check a few suppliers and POs in the new app against your ZIP before you trust it.

Phase 4 — after August 31

• The API is gone; only the read-only Shopify UI export remains for a while (no suppliers, no bulk line items). Your ZIP is now your only complete record — keep it safe.
• Cancel or reassess anything you were paying for around Stocky (for example companion label apps) so you are not billed for tools tied to a dead product.

Do Phase 1 today

Every later decision is reversible — the export deadline is not. Run the free exporter now, keep the ZIP, and you can take your time choosing a replacement without the API clock hanging over you.
