POS Integration Guide: Square, Shopify, Clover


Why POS Integration Matters


Your POS system already tracks every sale. POS integration means inventory software can:

  • Automatically decrement stock when you make a sale
  • Sync product catalog (names, SKUs, prices)
  • Track sales velocity per product
  • Predict stockouts before they happen

    • No POS integration = manual data entry + guesswork.


    How Stokkfy Connects to Your POS


    Square


    Connection Method: OAuth (one-click)


    What Gets Synced:

  • Product catalog (name, SKU, category, price, variants)
  • Current inventory levels
  • Sales history (12 months)
  • Real-time sales (inventory decrements instantly)

    • Sync Frequency: Real-time for sales, hourly for catalog updates


    Setup Time: 2 minutes


    Limitations:

  • Square's API doesn't expose supplier info (you'll add that in Stokkfy)
  • Inventory tracking must be enabled in Square

    • Best For: Retail stores, cafes, small restaurants


    Shopify


    Connection Method: OAuth (one-click)


    What Gets Synced:

  • Product catalog (title, SKU, variants, price, images)
  • Inventory levels per location
  • Sales history (unlimited)
  • Fulfillment status

    • Sync Frequency: Real-time via webhooks


    Setup Time: 3 minutes


    Limitations:

  • If you have multiple Shopify locations, you'll select which one to track
  • Shopify's inventory is location-specific

    • Best For: E-commerce stores, omnichannel retail


    Clover


    Connection Method: OAuth (one-click)


    What Gets Synced:

  • Item catalog (name, SKU, price, categories)
  • Inventory levels (if Clover inventory is enabled)
  • Order history
  • Modifier and variant tracking

    • Sync Frequency: Real-time for orders, hourly for catalog


    Setup Time: 3 minutes


    Limitations:

  • Clover's inventory features vary by merchant — some have basic tracking, others have full inventory management
  • Multi-location setups require location selection

    • Best For: Quick-service restaurants, retail stores


    Toast


    Connection Method: API key + partner integration


    What Gets Synced:

  • Menu items (food, beverages, modifiers)
  • Sales data (by item, time, location)
  • Inventory usage (if Toast inventory is enabled)
  • Recipe tracking (ingredients per menu item)

    • Sync Frequency: Real-time for sales, hourly for menu updates


    Setup Time: 5 minutes (requires API key from Toast dashboard)


    Limitations:

  • Toast focuses on restaurant operations — inventory tracking is basic compared to retail POS
  • Recipe-based inventory tracking requires setup in Toast first

    • Best For: Full-service restaurants


    WooCommerce


    Connection Method: WordPress plugin + API key


    What Gets Synced:

  • Product catalog (name, SKU, categories, variations)
  • Stock levels per product
  • Order history
  • Low stock alerts

    • Sync Frequency: Hourly sync (or on-demand via webhook)


    Setup Time: 5 minutes (install plugin, enter API credentials)


    Limitations:

  • Requires WordPress admin access
  • Works best with WooCommerce 5.0+

    • Best For: Online stores on WordPress


    Lightspeed Retail


    Connection Method: OAuth


    What Gets Synced:

  • Item catalog (name, SKU, supplier, cost, price)
  • Inventory counts per location
  • Sales history
  • Purchase orders

    • Sync Frequency: Real-time via webhooks


    Setup Time: 3 minutes


    Limitations:

  • Lightspeed has multiple products (Retail, Restaurant, E-commerce) — make sure you're on the right one
  • Multi-location requires location selection

    • Best For: Specialty retail, boutiques


    What Happens After You Connect


    Step 1: Initial Sync (5-30 minutes)

    Stokkfy imports:

  • Your entire product catalog
  • Current inventory levels
  • 12 months of sales history (for AI learning)

    • Step 2: AI Analysis (24-48 hours)

    Stokkfy's AI:

  • Identifies sales patterns (day-of-week trends, seasonality)
  • Calculates sales velocity per product
  • Detects slow-moving vs fast-moving products
  • Sets initial reorder points

    • Step 3: Ongoing Sync (Real-time)

    Every sale updates inventory instantly. Stokkfy monitors stock levels and predicts when you'll run low.


    Step 4: Auto-Reordering

    When AI predicts a stockout within your supplier's lead time, it generates and sends a purchase order automatically.


    Troubleshooting Common Issues


    "Some products didn't sync"

  • Cause: Product doesn't have SKU or barcode in POS
  • Fix: Add SKU in your POS, then re-sync

    • "Inventory levels are wrong"

  • Cause: Initial sync pulled stale data
  • Fix: Do a physical count, update POS, then re-sync

    • "Sales aren't updating in real-time"

  • Cause: Webhook not firing (Shopify, Clover) or API rate limit (Square)
  • Fix: Contact support — we'll re-establish the connection

    • "I have multiple locations"

  • Cause: POS supports multi-location, Stokkfy tracks one at a time
  • Fix: Connect each location as a separate business in Stokkfy

    • Security & Permissions


    What Stokkfy Can Access:

  • Read product catalog
  • Read sales history
  • Read inventory levels

    • What Stokkfy CANNOT Access:

  • Customer payment info (credit cards, bank accounts)
  • Customer personal data (beyond order names)
  • Ability to delete or modify products in your POS

    • Data Storage:

  • All data encrypted in transit (TLS 1.3) and at rest (AES-256)
  • Hosted on EU servers (GDPR compliant)
  • You can disconnect anytime (data deleted within 30 days)

    • Disconnecting Your POS


    If you want to stop syncing:

    1. Go to Settings → Integrations

    2. Click "Disconnect [POS Name]"

    3. Confirm


    Your POS data remains in your POS. Stokkfy stops syncing new sales.
