Petty cash in a notebook is how small businesses quietly lose 1-3% of revenue. Unrecorded expenses, "I forgot the receipt" claims, supervisor-friend approvals, and the year-end reconciliation that nobody fully closes. Going digital does not need to be complicated. It just needs a clear process, and here it is.

The petty cash problems digital solves

Lost receipts: a phone photo replaces paper
No category: every expense forced into a category at entry
No approval trail: every approval is recorded
End-of-month chaos: the running balance is always current
Audit anxiety: every entry is timestamped with who made it
Misuse: a second approval catches anything odd

The digital petty cash workflow

1. Set up petty cash accounts

One account per location / department / cost centre. Each has an opening balance, a monthly float top-up, and an authorised custodian.

2. Categorise expense types upfront

Common categories for Pakistani SMBs:

Office supplies (stationery, printing)
Refreshments (tea, water, snacks)
Travel (local taxis, fuel reimbursement)
Repairs and maintenance (minor)
Courier and postage
Cleaning supplies
Marketing materials (banners, flyers)
Customer recovery (refund, replacement)
Miscellaneous

Requiring a category at entry, instead of letting "miscellaneous" become the dumping ground, does more for control than anything else here.

3. Capture expense from mobile

The employee makes a purchase, opens the HR mobile app, takes a photo of the receipt, enters the amount, category and a short description, and submits. It takes about 30 seconds. The approver gets a push notification.

4. Two-step approval

Department head approves (yes, this expense is legitimate). Finance team verifies (amount matches receipt, category is correct, within budget). Disbursement / reimbursement happens after both approvals.

5. Running balance

Always-current balance per account. No need to "calculate" at month-end. The custodian and the finance team see the same number.

6. Monthly closure

End of each month, the petty cash account is reconciled: opening balance + top-up - approved expenses = closing balance. If actual cash on hand matches closing balance, account is closed for the month. Any difference gets investigated.

7. Category-wise reporting

Monthly report: how much spent per category, per location, per department. Trends month-over-month. Outliers flagged automatically.
