Real-time stock

Quantities update the moment you sell, purchase or transfer goods.

Multi-warehouse

Track and transfer stock across locations and branches with full visibility.

Low-stock alerts

Set reorder points and get warned before you run out of a fast mover.

Barcode & SKU

Scan to sell or receive, organised by SKU, batch and unit of measure.

Live valuation

Average or FIFO costing keeps inventory value accurate on your balance sheet.

Linked to sales

Invoices and purchase orders move stock automatically, no manual updates.

Always accurate

Inventory that updates itself

Manual stock counts go stale the moment you make a sale. In Paper & Pen, every invoice, purchase and transfer adjusts stock and cost in real time, so the number on screen is the number on the shelf. Set reorder points and let the system tell you when to buy.

  • Auto-adjusts on every transaction
  • Reorder points and alerts
  • Batch, SKU and unit-of-measure tracking

Stock meets the books

From shelf to balance sheet

Inventory is not just counting boxes, it is real money on your balance sheet. Paper & Pen values stock with average or FIFO costing and posts movements to accounting automatically, so your cost of goods sold and stock value are always reconciled. Works in any currency for any market.

  • Average or FIFO costing
  • Auto-posts to accounting
  • Multi-currency purchasing

Questions

Everything you need to know

Is inventory included free?
Inventory is an optional paid add-on. The core Sales & Invoicing module is free forever, and you add Inventory when you need real-time stock control.
Can I manage multiple warehouses?
Yes. Track stock per location, transfer between them and see live quantities everywhere.
Does it support barcodes?
Yes. Use barcodes and SKUs to sell and receive faster, with batch and unit-of-measure support.
How is stock valued?
Choose average cost or FIFO. Valuation updates with every movement and posts to your accounting automatically.
Does selling update stock automatically?
Yes. Invoices reduce stock and purchases increase it in real time, so you never update quantities by hand.
