Real Counter Systems in Action
Inspect how Lyndesk manages daily accounting, currency localization, and offline ledgers.
Dual Capital Tracking: Cash in Till vs. Bank Ledger
When starting your counter in the morning, Lyndesk asks you to verify your physical opening cash float. Throughout the day, counter sales automatically partition cash payments into your physical cash drawer ledger and digital card/UPI payments into your designated bank balance.
Comprehensive Commercial Capabilities
Everything needed to operate a retail shop, trading company, or service startup without relying on five separate SaaS subscriptions.
Point of Sale (POS) Counter Billing
Lightning counter checkout with instant USB/Bluetooth barcode scanner capture, automatic change tender calculator, customer credit ledgers, and raw 80mm/58mm thermal receipts. Hit F2 anywhere to bill instantly.
Inventory & Multi-Godown Warehouses
Track stock quantities across multiple warehouse locations. Low-stock warning thresholds, reorder badges, damaged item write-offs with audit notes, and chronological inbound/outbound movement history.
Customer & Vendor Ledgers (Parties)
Dual ledger system for Accounts Receivable and Accounts Payable. Record customer cash-in and vendor cash-out with running balance calculations and printable account statements.
