The leakage arithmetic
Take 80 bills a day at PKR 800 average: PKR 64,000 daily throughput. A 2% typing/shortfall error rate leaks ~PKR 1,280 daily — ~PKR 38,000 monthly. A POS plan at PKR 500/month pays for itself 70 times over before counting queues and stock effects (profit-calculation guide).
Five hidden calculator costs
- Pricing errors: remembered prices drift from shelf prices within weeks.
- Queue abandonment: waiting customers leave; regulars shorten visits (speed guide).
- Unrecorded sales: rush-hour cash bypasses the book entirely (sales-recording guide).
- Zero stock linkage: every reorder is a guess (inventory module).
- No customer history: credit decisions run on memory (ledger module).
When the calculator still wins
Under ~15 bills a day with fixed prices and no credit sales, the calculator remains rational. Cross any two of those lines and the POS has already earned its fee — verify with a free trial week measuring your own error rate.
Start with the 7-day full-feature trial, confirm pricing on the pricing page (500/mo · 4000/yr · 10000 lifetime till 30 Sep), and pay manually via admin WhatsApp — nothing is auto-charged. Verify official channels before paying.
