The challenge

A bustling neighbourhood smart mart operating two cash counters with heavy footfall. Credit customers were tracked in handwritten paper register books (khata). At closing time, reconciling cash from two tills against register entries took over two hours every night, leading to untracked stock shrinkage, manual calculation errors, and frequent customer disputes over past credit balances.

  • Paper Khata Ledger Errors: Handwritten notebooks resulted in lost credit entries and disputes with regulars over outstanding debts.
  • 2+ Hour Nightly Reconciliations: Manually tallying two separate cash drawers against paper slips exhausted counter cashiers every night.
  • Counter Checkout Queues: Lack of barcode scanning slowed customer checkouts during peak evening grocery runs.
Engineering The Solution

What we built

A synchronized two-counter offline POS running over local area network (LAN). Barcode scanning for fast checkout, customer-linked digital khata with real-time balance tracking, purchase order entry, supplier ledger management, and automated end-of-day till reconciliation that balances cash, card, and credit sales instantly.

📖 Digital Khata Ledger

Instant phone number lookup linking customer credit limits, past receipt histories, and automatic SMS ledger updates.

⚡ 2-Counter LAN Sync

Local network synchronization keeping both checkout tills sharing inventory balances in real time without requiring the internet.

🧾 1-Click End-of-Day Till

Automated reconciliation printing detailed till balances across cash, credit sales, discounts, and returned goods within seconds.

The result

Checkout time per customer dropped significantly during evening peak hours. Daily accounts closing and till reconciliation was cut from two hours to under ten minutes, with zero paper registers remaining on the counter.

<10m

Nightly reconciliation reduced from 2+ hours to under 10 minutes: Completely eliminating manual billing and khata bookkeeping discrepancies across both counter tills.
