Migrating from Stocky to Forthcast takes under 2 hours. Export your Stocky purchase orders and supplier data as CSV, install Forthcast from the Shopify App Store, let it auto-import your sales history, then re-enter active POs. Stocky shuts down on August 31, 2026 — after that, all data access ends.
⚠️ Critical dates: Stocky was removed from the Shopify App Store on February 2, 2026. Existing installs keep working until August 31, 2026, then full shutdown. Export your data while you still can.
Before you start
- An admin Shopify account that currently has Stocky installed.
- ~2 hours, ideally on a slow trading day so you can run both apps in parallel.
- A spreadsheet tool (Google Sheets / Excel) to hold the Stocky CSV exports.
Step 1 — Export your Stocky data
Open Stocky inside your Shopify admin and export the three datasets that don't survive the shutdown:
- Open purchase orders — Stocky → Purchase Orders → filter to Open → Export to CSV. You'll re-enter these in Forthcast in step 4.
- Supplier list — Stocky → Suppliers → Export. Capture lead times, MOQs, and contact emails.
- Forecasting & safety-stock settings — these were removed from the live UI in July 2025, but if you screenshotted them earlier, dig those out.
Step 2 — Install Forthcast and connect Shopify
Visit apps.shopify.com/forthcast and click Install. The OAuth handshake takes about 30 seconds; Forthcast then begins backfilling your full Shopify sales history. Most stores are ready in 5–15 minutes.
Step 3 — Settings parity
Open Forthcast → Suppliers and paste in the lead times from your Stocky CSV. Then go to Forthcast → Reorder rules and either accept the AI-suggested safety-stock thresholds or paste your old Stocky values. Forthcast's defaults are derived from your live Shopify sales velocity, so the recommendations are usually within 5–10% of what you had in Stocky.
Step 4 — Recreate active purchase orders
For each row in your Stocky open-PO export, go to Forthcast → Purchase Orders → New PO and re-enter it. For most Shopify stores this is 15–30 minutes total. Going forward Forthcast will auto-suggest reorder POs based on the demand forecast — you'll do this manually only this once.
Step 5 — Run in parallel for one week
Keep Stocky installed and run both side-by-side for ~7 days. Compare Forthcast's reorder suggestions against what Stocky would have flagged. This is the cheapest possible safety net, and it makes the cut-over a non-event.
Step 6 — Sunset Stocky before August 31, 2026
Don't wait for the shutdown. As soon as the parallel-validation week finishes and you trust Forthcast's reorder output, uninstall Stocky from your Shopify admin — ideally weeks before the August 31, 2026 deadline. Keep the CSV exports in long-term storage for audit purposes. After August 31, 2026, all Stocky data access ends — there is no API, no rescue export, and no historical UI.

How long does the migration actually take?
Under 2 hours of hands-on time for most Shopify stores: ~15 min to export from Stocky, ~30 min for the Forthcast install + backfill to settle, ~30 min for settings parity, ~15–30 min to recreate active POs.
Will my historical data come across?
Your Shopify sales history (the source of truth for forecasting) imports automatically. Stocky-specific data — manual forecasts, custom PO statuses, supplier notes — needs the CSV export route described above.
What if I miss the August 31, 2026 deadline?
Stocky access ends fully on that date. Forthcast can still pull your Shopify sales history afterwards, but anything that lived only in Stocky (manual notes, supplier custom fields) is gone. Export now.
Why not just stay on Stocky until the deadline?
Forecasting was already removed in July 2025. Running Stocky in 2026 means flying blind on demand. The earlier you cut over, the more forecast data you accumulate inside Forthcast before you actually need to act on it.
For a wider comparison of the alternatives, see Stocky was acquired by Shopify (then sunset) — is Forthcast the better alternative?.
