Run your stock smarter: decide when and how much to order, track how fast stock sells, price for wholesale and retail, create SKUs and purchase orders, and print packing slips and shipping labels.

Calculate when to reorder stock: reorder point = daily demand × lead time + safety stock, with safety stock from maximum usage and lead time.

Find the economic order quantity — the order size that minimises total ordering and holding costs — plus orders per year and the total cost.

Inventory Turnover

Calculate inventory turnover (COGS ÷ average inventory) and days inventory outstanding — how many times you sell through your stock in a year.

Wholesale Price

Set your wholesale price from unit cost with a markup or margin, and see the suggested retail price (MSRP) and the profit at each step.

Purchase Order Generator

Create a purchase order (PO) for your supplier: vendor and ship-to addresses, SKUs, quantities, unit prices, tax, delivery date and payment terms. Print or save as PDF.

Packing Slip Generator

Make a packing slip for an order: ship-to address, order number, carrier, tracking, SKUs and quantities ordered and shipped — no prices. Print it for the parcel.

Shipping Label Generator

Create a printable shipping label with sender and recipient addresses, tracking barcode, weight, dimensions and handling note — 4×6 thermal, A6 or A4.
