What is profit leakage?
Profit leakage is money lost through costs or concessions that are not visible in your headline sales number. An order can look profitable at quotation stage and earn much less after rework, extra delivery, wastage or an unrecorded discount.
For an engineering workshop, retailer or service business anywhere in Tamil Nadu, start with the last ten completed orders. Compare what you quoted with what you actually spent. These are illustrative business situations, not customer case studies.

A worked example: the order that looked profitable
Illustrative example, excluding GST: a job billed at ₹50,000 has ₹30,000 in material costs and ₹10,000 in direct labour. That leaves ₹10,000 before overheads. Add ₹3,000 in rework, ₹2,000 in extra delivery and a ₹2,000 discount, and only ₹3,000 remains before rent, administration and other overheads.
The sale did not disappear. The margin did. Record these extra costs against the job so the next quotation reflects the actual work.
Audit five places where margin can escape
Discounts: record who approved each concession and why. Compare the final invoice with the agreed price.
Rework and returns: log the cause, material used and staff time. Separate a quality failure from a customer-requested change.
Delivery and purchase costs: include freight, urgent buying and subcontract work rather than leaving them outside the order review.
Stock losses: compare physical counts with records and investigate damage, expiry or missing items.
Unreviewed expenses: check subscriptions, petty cash and repeat purchases. Separate owner withdrawals from operating expenses.
Run a 30-minute weekly margin review
Choose five completed orders. For each, write the billed amount, direct costs, unplanned costs and remaining contribution. Assign one person to investigate the largest gap and record a corrective action with a review date.
Use the findings to adjust quotation checklists, approval rules or quality checks. Do not assume that cutting every expense is the answer; understand what caused the loss first.
Profit and cash need different checks
A profitable invoice can still be unpaid. A customer advance can improve your bank balance before you have earned a profit. Pair this margin review with a cash-flow forecast; your accountant can help classify costs, tax and timing correctly.
