Medical Inventory — Your Data, Only You Can See
Inspection, Delivery, Reconciliation — All in One
Your digital patrol partner — built for medical device distributors. Counts daily, reconciles monthly, covers you during outages — no more LINE numbers or month-end Excel chaos.
Your Data, Only You Can See
Data is encrypted on your phone before it ever leaves. Even we can't read your customer lists or inventory numbers — only you can.
Lot & Expiry — Scan and Done
Scan a barcode to capture lot numbers and expiry dates. When auditors come, pull reports in one click — no digging through paper files.
Scheduled Reminders
System auto-creates tasks based on each site's inspection schedule. Get notified when stock runs low — no relying on memory.
Loans & Returns, Crystal Clear
Loaning gear to partners? Track it properly instead of digging through LINE. Create a record, set a return date, never lose track.
Hospital Price Change Alerts
System checks public NHI data daily. When a hospital changes their self-pay device pricing, you get an email right away.
Delivery Records, Price Locked on the Spot
Wartime emergency medical station: sales rep delivers to the station, picks items and fills quantity on the Laisun Pro touchscreen — price locks instantly, receipt auto-generated. Works fully offline; hospital and supplier each keep their own ledger for bilateral reconciliation.
Purchase Prices — Hospital Decides
Wartime emergency medical station: distributor quotes a price in the app, the medical station confirms or edits on the touchscreen — confirmed prices auto-apply. Every step is recorded: who quoted, who approved, when it took effect. Hospital and supplier can independently reconcile their accounts.
