Warehouse mobile app

The Warehouse mobile app is built for handheld scanners: receive inbound shipments, pick outbound orders, count stock, and move locations — all with barcode scanning at every step.

Overview

• Android only (industrial scanner support is mature on Android; iOS has limited Bluetooth-scanner ecosystem in warehouses).
• Login is by WMS user code + PIN (issued by warehouse manager); separate user pool from web-app users.
• Scanner support: built-in camera scanner works on any phone; for high-throughput sites pair a Bluetooth ring scanner or a dedicated handheld (Honeywell, Zebra).
• Offline-first: pick lists and inbound expectations cache; sync when connectivity returns.

Daily flows

Inbound (GRN)

1. 1
   Manager creates an expected inbound from the web (or it auto-creates from a Booking).
2. 2
   Receiver opens the app, scans the inbound's barcode (printed on the dispatch note).
3. 3
   Scans each SKU as it's received; quantity defaults to expected, override if short / over.
4. 4
   Scans the bin location each item is put away to (or the manager pre-assigned bins).
5. 5
   Tap Complete Receipt — generates the GRN, updates stock levels.

Outbound (Pick)

1. 1
   Manager releases a pick list from the web (or it auto-creates from a Shopify / WooCommerce order).
2. 2
   Picker opens app → My Picks → grabs the next pick.
3. 3
   App walks them through the bins in optimal order; scans each SKU to confirm.
4. 4
   If a SKU is short, picker marks it; manager gets notified to allocate from another bin.
5. 5
   Picker confirms completion at the pack station; pick list moves to packed state.

Cycle counts

1. 1
   Manager schedules a cycle count (one zone, one ABC class, or random sample).
2. 2
   Counter opens app → Counts → next assigned bin.
3. 3
   Scans every SKU in the bin; enters quantity.
4. 4
   App highlights variances vs system; counter rescans to confirm.
5. 5
   On completion, the variance becomes a stock-adjustment proposal — manager approves or rejects.

Common pitfalls

Permissions on the device

Required:

• Camera (barcode scanning).
• Notifications (new pick assignments).
• Storage (offline cache).

Optional:

• Location (for warehouse-zone enforcement; pickers should only work in their assigned zone).
