#01The 'Mental Hishab' Trap
You pull 500 Taka from the till to pay a supplier for tea/snacks, but forget to write it down. You think 'I will remember'. You won't. Small unidentified expenses account for 5-8% of lost margin in small shops.
#02The 'Baki' Black Hole
You sell 5000 Taka on credit. You write it in the customer's page. But you don't subtract it from your daily sales total. You think you made profit today, but you actually have no cash. You buy more stock, and suddenly you can't pay rent.
#03Ghost Inventory (Churi/Loss)
Your book says you have 100 Coke bottles. You actually have 92. Where did 8 go? Staff drinking? Breaking? Wrong delivery? If you don't count, you don't know.
#04Pricing Memory Loss
Supplier raised the price of rice by 2 Taka. Your staff forgets and sells it at the old price. You just lost your entire profit margin on that bag.
#05Stocking 'Feeling' vs 'Fact'
You 'feel' like detergent sells well, so you buy 50 cartons. It sits there for 6 months. That money is dead. Meanwhile, you ran out of sugar in 2 days.
