Loaned Bottle Deposit (Kardex) Control on Routes

Learn how to track every 20L water bottle across your fleet, prevent container losses, and maintain 100% audited bottle custody.

01

The Jug Loss Problem: Vanishing Assets

In conventional water plants, up to 15% of 20L jugs vanish annually because couriers leave loaned containers without strict digital assignment.

Direct savings: New polycarbonate jugs cost $4 to $7 USD each. Protecting 500 jugs represents thousands of dollars in preserved capital.
02

1-Tap Customer Bottle Balance Logging

On every stop, the courier logs: full bottles delivered (e.g. 3) vs. empty jugs returned (e.g. 2). The system updates the customer ledger automatically: +1 jug balance.

Customer ledger: Customer file displays exact bottles in custody and retention age.
03

Configurable Credit & Deposit Thresholds

Set maximum loaned jug caps in the Web ERP (e.g., max 2 bottles without cash deposit). When breached, the app prompts couriers to collect container deposits.

Clear rules: Prevent sporadic customers from hoarding your physical inventory.
04

Global Kardex & End-of-Day Reconciliation

At day end, the master Kardex balances: full stock + empty plant inventory + truck stock + customer custody = 100% of your assets accounted for.

Bottle Deposit Control FAQs

What if a customer returns a broken or unauthorized jug?

The courier marks "Rejected / Damaged Bottle" and charges replacement cost to the customer without creating route imbalances.

Can I see which customers have held bottles for over 30 days?

Yes. The Web ERP includes an "Overdue Bottle Custody Report" with 1-click automated WhatsApp reminders.
