Every feature
The full Hydra INV feature list
Beyond the highlights — everything the app does, organized by category.
Hydra INV v3.20
Stock & Inventory Control
- Item catalog with FIFO batch tracking and running average cost
- Full movements log — every receive, sale, waste, correction and transfer
- Low-stock and expiry alerts on the dashboard
- Guided stocktaking (physical count) workflow
- Dashboard KPIs — today's activity and a 7-day trend, on local calendar time
- Daily email alert, at the hour you choose, when something is low on stock or about to expire — and no email on a quiet day
Recipes & Automatic Costing
- Recipe builder mapping ingredients to POS/PMS products
- Live cost-per-portion calculation from current ingredient prices
- Recipe export to CSV, one row per ingredient, with cost data
- Automatic stock deduction on POS sale close, day-close batch, PMS minibar charge, or storno reversal
- POS catalogue sync: Hydra POS sends its products, variants and prices to INV (at day close or on demand), so a recipe is linked by picking from a searchable list and food cost % is worked out from the synced selling price
- Bulk recipe import and delete, recipe search, and variants grouped under their base product
Purchasing & Suppliers
- Supplier directory with order history
- Purchase orders with email sending built in
- Automatic reorder suggestions from minimum stock levels and consumption data
Multi-Location & Assets
- Per-site stock tracking with transfers between locations
- Fixed asset registry
- Depreciation tracking over time
Equipment Lending
- Checkout / return tracking with due dates
- Reminders for overdue lent-out equipment
- GDPR-compliant deletion of a borrower's personal data while keeping the quantity record
Scanning, Anywhere
- Built-in camera barcode scanning
- WiFi / Bluetooth hardware scanner support
- Phone-based scanner bridge page — no app install needed
- Dedicated tablet receiving mode with a scoped, receiving-only API key
- Tablet stocktake: count with the tablet's camera and record the variance, next to receiving
Access & Security
- PIN-based quick login for shared devices, with three roles — staff, manager, admin
- Every stock movement records who performed it — full audit trail
- Automatic logout after 5 minutes of inactivity
- Scoped integration API keys — grant only read, sell, storno or day-close, not one master key
- Rate limiting and quantity caps on POS/PMS endpoints against a faulty or compromised client
- Sign-in history for shared PCs — who signed in and out, with manual and automatic inactivity logouts marked — with CSV export; the automatic logout can be switched off for a single-user machine
Integration & the Inventory PWA
- Local HTTP/HTTPS API for Hydra POS and Hydra PMS
- Check live stock, low-stock and expiry warnings from your phone via the installable Inventory PWA
- Portfolio view across every establishment you manage, with a combined roll-up
- Read-only, property-scoped access — the same code your Manager app already uses
- Cloud backup once a day or on demand (passwords and keys left out), a second backup folder (for example a OneDrive or Dropbox folder), and email alerts when backups keep failing, disk space runs critically low or no daily backup has completed for two days
