Inventory & Purchasing · Free as your first app
Stock you can actually trust.
Track every lot, expiry and serial across your shop, storeroom, kitchen and van. Count with your phone camera, turn recipes into production at real cost, and let par levels draft your purchase orders.
What you get
Stock you can actually trust.
Every location
Shop, storeroom, kitchen, van and warehouse — with transfers, waste and opening balances.
Lots and expiry
Batch, expiry and serial tracking, first-expiry-first-out. Stock can never go negative.
Counts with your camera
Snapshot counts with camera barcode scanning and an approval step.
Recipes and production
Recipes with yield and sub-recipes; production uses real lots at actual cost. Print AR/EN recipe cards at any portion size.
Purchase orders that draft themselves
Par levels create draft POs; receive in parts, over-receipts are blocked, and landed cost is allocated.
Send POs on WhatsApp
Share a purchase order with your supplier as a ready WhatsApp message. Every stock movement posts a balanced entry.

Good questions.
Does selling deduct stock?
Yes. The sold item is deducted from the right lot at its actual cost.
