Stock tracking is available on Starter and Pro. When a non-draft invoice contains an inventory product, WadMaster posts a sale movement and reduces that product's quantity on hand. Editing the invoice posts only the quantity difference.
Deleting an invoice that has no payments returns the stock; draft invoices do not hold stock. Each movement remains visible in the product's stock history.
Set a reorder level on each tracked product. When quantity on hand reaches or falls below it, WadMaster shows the product as low stock in inventory views. Stock tracking is included on Starter and Pro; automated low-stock email alerts are a Pro feature. Free does not include stock tracking, and Starter does not send the automated low-stock email.
Enter a selling price and, when known, a cost price for the product. WadMaster shows per-unit profit as selling price minus cost price, and margin as that profit divided by selling price. Starter and Pro include inventory margin reporting and product-performance views in Insights. If a sold line has no recorded cost, WadMaster marks that margin as unavailable or incomplete instead of treating the cost as zero.
Free plan supports up to 10 products, Starter plan supports up to 200 products, and the Pro plan offers unlimited products.
