How to manage petty cash and small expenses without losing control

Petty cash and small expenses are a common source of financial leakage in Indian companies — not because anyone is necessarily dishonest, but because the controls are minimal and the accountability is unclear. The total annual leakage from uncontrolled petty cash in a 50-person company can be surprisingly significant.

Define what petty cash is for. Petty cash should cover small, immediate cash expenses that can't be done by bank transfer or corporate card — typically below ₹1,000–2,000 per transaction. Office stationery, small refreshments, courier charges, and emergency small purchases. It should not be used for travel advances, vendor payments, or any transaction that can be done through the normal payment process.

Imprest system: give each petty cash custodian a fixed float (say ₹5,000–10,000). When the float is spent down to a threshold, they submit vouchers for all expenses and the float is topped up to the original amount. Every transaction needs a voucher with date, amount, purpose, and (where possible) a receipt. The custodian is accountable for the float — if the physical cash plus vouchers doesn't add up to the float amount, there's a discrepancy to explain.

Surprise cash counts. Every month or two, an unannounced count of the petty cash float — verifying that physical cash plus outstanding vouchers equals the float — is the primary control. Unannounced counts are far more effective than announced ones.

For most expenses, use corporate cards or reimbursement, not cash. The best solution for a growing company is to eliminate most petty cash by: giving key staff corporate debit/prepaid cards with defined limits and merchant categories, and running an expense reimbursement system for staff who advance their own money for business expenses. Digital expense management tools (Zoho Expense, Happay, Volopay) make this trackable without requiring physical receipts.
