Inventory
The Inventory section of Shillinq tracks your physical stock — what products you hold, where they are, how many there are, and what they are worth. It integrates directly with the financial ledger so every inventory movement automatically generates an accounting entry.
Pages in this section
Products
The Products list is your product master — every item you buy, sell, or manufacture. Each product record contains:
| Field | Purpose |
|---|---|
| SKU / barcode | Unique identifier for scanning and ordering |
| Description | Human-readable name |
| Unit of measure | Piece, kg, litre, hour, etc. |
| Cost method | FIFO, LIFO, or average cost |
| GL account (stock) | The balance sheet account for this product's inventory value |
| GL account (COGS) | The P&L account for cost-of-goods-sold when the item is sold |
| Reorder point | When to trigger a reorder |
| Lead time | Days between ordering and receiving |
Stock levels
The Stock levels page shows real-time quantities per product. If you have multiple warehouses or locations, use Stock by location to see the breakdown per location.
Stock by location
Shows stock quantities split across storage locations. Useful if you have a main warehouse plus a shop floor or bonded warehouse.
Reserve stock
The Reserve stock page shows stock that has been committed to a sales order but not yet shipped. Reserved stock reduces available stock in real-time.
Barcodes
Manage GS1 / EAN / QR codes assigned to products. Multiple barcodes can be assigned to one product (e.g., product barcode + packaging barcode).
Lots & Batches
Track individual production lots or batches — required for food, pharma, and other regulated industries. Each lot carries a production date, expiry date, and the quantity still available from that lot.
Expiry alerts
The Expiry alerts page lists lots that are approaching or past their expiry date. Configure how many days before expiry to trigger an alert in Settings → Inventory → Expiry warning days.
Inventory valuation
Shows the book value of your entire inventory, calculated per product using your chosen cost method (FIFO, LIFO, or average). Use this to verify the inventory balance sheet account against the general ledger.
Reorder rules
Automated reorder rules trigger purchase suggestions when stock falls below the reorder point. Each rule sets:
- Minimum stock level
- Order quantity (or weeks of supply to order)
- Preferred supplier
- Lead time
Triggered rules appear in Purchasing & Inventory → Purchase orders as draft orders for your approval.
Low-stock alerts
The Low-stock alerts page lists products that are at or below their reorder point but haven't been reordered yet. Review and approve the pending purchase orders from here.
Inventory and accounting
Every inventory movement (goods receipt, goods issue, revaluation) generates an automatic journal entry. The posting logic is configured in Settings → Inventory → GL posting configuration:
| Event | Debit | Credit |
|---|---|---|
| Receive goods | Stock account (asset) | AP / GR clearing |
| Ship goods (sales) | COGS (expense) | Stock account (asset) |
| Return to supplier | AP / GR clearing | Stock account (asset) |
| Revaluation | Stock account or adjustment | Revaluation reserve |
