Stocky is going away. Now what?
Shopify says the Stocky app will no longer be available after August 31st, 2026. If you relied on it for purchase orders, incoming transfers, or supplier inventory tracking, you need a transition plan.
The right replacement depends on which part of Stocky you actually used. There is no single 1:1 clone across supplier-file automation, purchase orders, transfers, and multi-channel inventory.
This guide compares five options using public product materials reviewed in March 2026 and the workflows each tool appears to target.
What to look for in a Stocky replacement
Before comparing tools, clarify which Stocky workflows actually matter to your store:
- Supplier file ingestion — Do your suppliers send CSV, Excel, or PDF files by email?
- Inventory accuracy — Do you need safety checks before stock levels change?
- Multi-location support — Do you manage inventory across multiple warehouses or retail locations?
- Purchase order management — Do you create and track POs inside your inventory tool?
- Multi-channel sync — Do you sell on Amazon, eBay, or other channels besides Shopify?
No single tool covers all five. The right choice depends on which workflows drive revenue and which ones cause the most pain.
1. GhostSync — Best for supplier email automation
GhostSync is purpose-built for merchants whose suppliers send inventory files by email. It watches a forwarding address, parses CSV, Excel, and PDF attachments, maps SKUs with AI-assisted onboarding, and pushes inventory deltas to Shopify automatically.
What sets it apart is the safety-first approach. Every sync runs through guardrails that block wipe-risk files, partial updates, and format drift before anything touches Shopify. You can start in preview mode to see exactly what would change before going live.
Strengths
- Automated supplier email ingestion (CSV, XLSX, PDF)
- AI-assisted SKU mapping during onboarding
- Safety guardrails block bad data before Shopify updates
- Preview mode for risk-free validation
- Push-based — updates start when the email arrives, not on a schedule
Limitations
- No purchase order management
- No demand forecasting
- Best suited for supplier-driven inventory, not warehouse ops
Best for: Merchants who receive supplier inventory files by email and need safe, automated Shopify updates without manual reformatting.
2. Stock Sync — Best for feed-based sync
Stock Sync's public docs describe scheduled updates from suppliers, warehouses, or drop-shippers across sources like FTP/SFTP, download URLs, Google Sheets/Drive, Dropbox/OneDrive, and email attachments.
It looks strongest when supplier data already lives at a stable endpoint or when you want a broad product and inventory sync surface beyond an inbox-first tool.
Strengths
- Supports a wide range of sources including hosted feeds and email attachments
- Broader product and inventory sync scope than an inbox-only workflow
- Long Shopify App Store history
Limitations
- Public docs emphasize scheduled updates rather than push-on-arrival inbox automation
- No public PDF parsing documentation
- Broader configuration surface than a dedicated supplier-email inventory tool
Best for: Merchants whose suppliers provide hosted inventory feeds via URL or FTP.
3. Sumtracker — Best for multi-channel inventory
Sumtracker focuses on keeping inventory in sync across multiple sales channels — Shopify, Amazon, eBay, Etsy, and WooCommerce. It also handles bundles, kits, and composite products.
If your primary problem is overselling across channels rather than supplier file ingestion, Sumtracker solves a different (and complementary) problem.
Strengths
- Multi-channel sync across Shopify, Amazon, eBay, Etsy
- Bundle and kit inventory tracking
- Purchase order management included
Limitations
- Supplier email attachments are not a highlighted workflow in the public materials reviewed
- PDF parsing is not highlighted in the public materials reviewed
- Designed around multi-channel inventory planning rather than supplier-file onboarding
Best for: Multi-channel sellers who need unified inventory across marketplaces.
4. EZ Inventory — Best for scheduled quantity-feed updates
EZ Inventory's public app-store materials focus on bulk quantity updates from CSV, Excel, JSON, or XML feeds. It supports manual uploads or scheduled pulls from FTP/SFTP and website URLs, plus multi-location support.
It fits merchants who already have hosted quantity feeds and mainly need scheduled inventory updates inside Shopify rather than supplier inbox automation.
Strengths
- CSV, Excel, JSON, and XML feed support
- Manual and scheduled quantity updates
- Multi-location support is called out publicly
Limitations
- Supplier email attachments are not a documented input source on the current app page
- No public PDF parsing documentation
- Focused on quantity updates rather than onboarding or migration workflows
Best for: Merchants with hosted quantity feeds who want scheduled inventory updates inside Shopify.
5. EasyCSV — Best for CSV/XLSX workflow automation
EasyCSV's public app-store page positions it as a broad CSV/XLSX automation tool for imports, exports, orders, pricing, and stock sync across email, FTP, links, URLs, and Google Sheets.
It can automate spreadsheet-heavy workflows well, but it is broader and less inventory-specific than a tool built solely around supplier email attachments.
Strengths
- Supports email, FTP, links, URLs, and Google Sheets sources
- CSV/XLSX mapping plus filters for bad or incomplete data
- Alerts, logs, and both manual and automated flow types are called out publicly
Limitations
- No public PDF parsing documentation
- Broader workflow tool rather than an inventory-specific guardrail surface
- May take more configuration if all you want is supplier email inventory automation
Best for: Merchants who want broad CSV/XLSX automation beyond inventory-only workflows.
Comparison at a glance
| Feature | GhostSync | Stock Sync | Sumtracker | EZ Inventory | EasyCSV |
|---|---|---|---|---|---|
| Primary fit | Supplier email inventory automation | Broader product and inventory feed sync | Multi-channel inventory planning | Scheduled quantity-feed updates | CSV/XLSX workflow automation |
| Email attachment workflow | Purpose-built | Supported | Not highlighted in public docs | Not documented on the current app page | Supported |
| Hosted feed / URL sources | Not the core workflow | Yes | Not highlighted in public docs | Yes | Yes |
| PDF parsing in public docs | Yes | Not listed | Not listed | Not listed | Not listed |
| Runtime posture | Push-based email ingestion | Scheduled supplier and feed updates | Cross-channel inventory sync | Manual or scheduled quantity updates | Manual, trigger-based, or scheduled flows |
| Review and alerts | Preview mode plus inventory guardrails | Preview sync, notifications, and quantity rules | Depends on workflow | Email error notifications | Filters, alerts, and detailed logs |
How to decide
Start with your actual workflow, not feature lists:
- If your suppliers email you files → GhostSync
- If your suppliers host a feed at a URL → Stock Sync
- If you sell on multiple marketplaces → Sumtracker
- If you need scheduled quantity-feed updates from hosted files → EZ Inventory
- If you want broad CSV/XLSX workflow automation → EasyCSV
Many merchants use two tools: one for supplier ingestion and one for multi-channel sync. GhostSync and Sumtracker, for example, solve complementary problems and can run side by side.
Migrating from Stocky
If you are currently on Stocky, the transition does not have to be painful. Shopify's migration docs say Stocky will end after August 31, 2026 and note that some records need manual export, so capture the data you need early. Then set up your replacement tool with one supplier first, validate the sync in preview or test mode, and expand once you trust the output.
GhostSync includes a Migration Concierge that helps classify your Stocky exports and stage a safe cutover.
