Profit is an Opinion, Cash is a Fact: Mastering Credit Limits

Why high-revenue companies still face bankruptcy. The strategic role of Credit Limits in safeguarding cash flow.

Profit is an Opinion, Cash is a Fact: Mastering Credit Limits

In my 20 years of implementing ERP and DMS systems, I have seen many CEOs fall into the ‘Phantom Revenue’ trap. Contracts are signed, warehouses are emptied, yet when payday comes, the treasury is dry.

The culprit? A lack of discipline in Accounts Receivable (AR) and Credit Limit management.

1. Revenue is Vanity, Cash is Sanity

Sales Directors often pressure Accounting to loosen Credit Limits to hit sales KPIs. They forget one fundamental truth: A sale is only complete when the cash hits your bank account.

“Selling without collecting is just giving away your inventory while paying for the privilege of doing so.”

In markets like Vietnam, the culture of ‘rolling debt’ is deeply ingrained. If your management system isn’t rigid, customers will naturally use your capital to finance their own operations for free.

2. Credit Limit: More Than Just a Number

In a world-class ERP system, a Credit Limit isn’t arbitrary. It must be a calculated synergy of payment history, financial credibility, and market penetration strategy.

MetricLoose Management (Intuitive)System-Driven Management
DSO (Days Sales Outstanding)Usually > 60 days, erraticStable at 30-45 days
Bad Debt RatioHigh, frequent write-offsLow, early warnings triggered
Cash FlowPrecarious, reliant on short-term loansProactive, optimized Working Capital
Sales DecisionsBased on personal relationshipsBased on real-time Credit Scoring

3. Field Lessons: Blocking Risk at the Source

I once rescued a FMCG distributor that had lost control of its AR to the point where they didn’t know which sub-dealers were over their limits. The solution wasn’t debt collection; it was rebuilding the ‘Checkpoint’ within the system:

  1. Hard Stop: The system automatically blocks warehouse release (Block Order) the moment a customer hits their Credit Limit or has an Overdue balance—even by one day.
  2. Approval Hierarchy: Only the CFO has the authority to ‘Release’ exceptional orders, removing the conflict of interest from the Sales team.
  3. Real-time Aging Reports: Instead of waiting for month-end reports, the system must push daily debt aging alerts to field staff via Mobile Apps.

Final Thought

Managing AR and Credit Limits isn’t about stifling growth. On the contrary, it is the braking system that allows the corporate vehicle to drive faster without crashing at the financial curve. Don’t wait for a liquidity crisis to tighten your processes. Let the system play the ‘bad guy’ so you don’t have to.
