Inventory & Margin
Know what you have. Know what it costs.
From supplier receipt to plate cost, Perko connects stock, recipes, sales, valuation, and review.
The leakage problem
The invoice, recipe, and count can each look right — while the difference remains unexplained. Purchases, consumption, and waste drift apart across separate records.

Purchase capture
- Receipt ingestion
- Upload or forward the supplier document. Perko extracts the supplier, date, items, quantities, and unit costs.
- Verification
- A human checks the extracted data against the original. One‑click approve or correct.
- Immutable record
- Approved receipts become append‑only stock‑in records. No editing without a documented correction.
Receiving
- Match what arrived
- Mark each line as received, partially received, or rejected. Partial deliveries create an open remainder, not a silent gap.
- Quality notes
- Record condition, expiry, batch, or rejection reasons directly on the receipt.
Recipes and plate costing
- Reviewed recipes
- Every sellable item has a versioned recipe with exact bill of materials. A recipe is not a suggestion — it drives costing, stock consumption, and availability.
- Real‑time cost
- The plate cost recalculates when a supplier price changes. No end‑of‑month surprise.
- Yield and prep loss
- Trim, evaporation, and batch yield factor into the cost model. What you sell is what you cost.
Stock movements
- Append‑only ledger
- Every purchase, consumption, transfer, count adjustment, and waste record is an immutable movement. Nothing is overwritten.
- Available‑to‑sell
- Sales consume stock per the reviewed recipe. The available quantity reflects confirmed receipts minus confirmed consumption and waste.
- Low‑stock and expiry alerts
- Configurable thresholds alert before you run out or before an item expires on the shelf.
Blind counts and margin review
- Blind counts
- A count sheet shows only the item name and location — no expected quantity. Count what is there, not what you hope is there.
- Variance before adjustment
- Every discrepancy is visible before any adjustment is applied. The owner sees the gap and decides.
- Margin at every level
- Margin by recipe, by category, by supplier, and by period. Stock moves, sales, and costs tie to the same ledger.
