Profitable and broke: why margin is not money

A business can be profitable on every page of its accounts and still be unable to pay salaries. This is not an accounting anomaly. It is arithmetic, and it happens most often to businesses that are growing quickly, which is precisely when it is least expected.

Why the two diverge

Profit is recorded when you raise an invoice. Cash arrives when the customer pays. Between those two events sits a gap, and the size of that gap multiplied by your growth rate is the amount of money your business consumes simply by getting bigger.

Consider a business selling on sixty-day terms whose revenue doubles. Profit doubles on paper. Meanwhile receivables have also roughly doubled, and that increase is money that has left the business, spent on delivering the work, but not yet returned.

Growth consumes cash. The faster you grow, the more it consumes.

Cause one: receivables quietly stretching

Rarely a single customer refusing to pay. More often it is every customer paying a little later than before, while nobody tracks the average.

Ten extra days across all customers on a business with meaningful monthly revenue is a substantial sum permanently removed from your bank account. It does not come back until you either shrink or collect harder.

What to watch: receivable days, monthly, plotted over time. Not the total outstanding, the days. Totals rise naturally with growth; days rising means something changed.

Cause two: inventory absorbing the growth

For anyone holding stock, the same mechanic with a different name. A business anticipating growth buys ahead. If the growth is slower than the buying, the difference sits in the warehouse.

Inventory is the easiest place for cash to hide, because unlike a receivable nobody is chasing it and it does not appear overdue. It simply sits, fully valued in the accounts, until someone counts it properly.

The aggravating factor: paying faster than you collect

If you pay suppliers in thirty days and collect in seventy-five, you are funding forty-five days of your customers' working capital out of your own pocket, every single cycle.

This is the cash conversion cycle, and it is the number that determines whether growth makes you rich or makes you borrow. It is worth noting here that the MSME payment rules impose real constraints on how long you can stretch payables to registered micro and small suppliers, so lengthening the payables side is not always an available lever.

The report that prevents all of this

One page, monthly, carrying five things:

• Receivable days, this month and the trend
• Inventory days, this month and the trend
• Payable days, this month and the trend
• The resulting cash conversion cycle
• A thirteen-week forward cash forecast

The first four tell you what has happened. The fifth tells you what is about to. A thirteen-week horizon is the useful one, long enough to act, short enough to be credible.

What to do when the gap opens

In order of speed:

1. Invoice on the day the work completes. The commonest delay in getting paid is the delay in asking.
2. Chase at day one overdue, not day thirty. A polite note on the due date changes payment behaviour more than escalation a month later.
3. Take deposits on large orders. Standard in most industries; usually not asked for.
4. Look at your slowest-paying customers alongside their margin. Sometimes the customer costing you the most cash is also the one earning you the least.

The sentence worth remembering

Profit is an opinion about a period. Cash is a fact about a day. When they disagree, the cash is the one that stops your business.
