South African SMEs: 6 Working Capital Fixes to Stop Missed Payrolls

Business owner checking a payroll payment

Working capital is simply current assets minus current liabilities: the cash and near-cash resources your business has to cover what it owes in the next twelve months. A positive number means you can pay short-term bills and still have room to reinvest. A negative one means cash pressure is building, and you need to check it monthly, not once a year at tax time.

Executive Summary

  • Maintaining a working capital ratio between 1.2 and 2.0 is generally healthy; below 1 suggests potential difficulty in meeting short-term obligations.
  • Improving inventory turnover and speeding up invoicing and collections can significantly enhance profitability and cash flow sustainability.
  • Industry sector norms vary: retailers hold more inventory, service firms have higher receivables, and manufacturers carry both, affecting working capital needs.
  • Regularly tracking the cash conversion cycle helps identify bottlenecks in stock, receivables, and payables that could threaten liquidity.
  • Using automation or professional CFO advice becomes necessary when recurring shortfalls or complex supply chains hinder manual management.

Working capital formula and the balance-sheet terms you need to know

Working capital has one core formula: current assets minus current liabilities. A related measure, the working capital ratio, divides current assets by current liabilities to show how many times over you can cover short-term debts, according to Statistics South Africa.

To calculate either figure, you need two groups of numbers straight from the balance sheet:

  • Current assets: cash in the bank, money owed by customers (accounts receivable), and stock on hand (inventory).
  • Current liabilities: money owed to suppliers (accounts payable), short-term loans, and any tax payable within the year.

“Net working capital” is just the formal term for the same subtraction most people call “working capital” in conversation, a point confirmed by Investopedia’s definition. Don’t confuse it with cash flow: working capital is a snapshot of position on a given date, while cash flow tracks money moving in and out over a period.

What working capital looks like for different small businesses

The same formula produces very different pictures depending on what you sell. A retailer’s working capital is dominated by inventory sitting on shelves. A service business barely holds stock but can have large accounts receivable if clients pay slowly. A small manufacturer often carries both raw materials and work in progress, stretching the cycle further.

Typical current assets and liabilities include:

  • Cash, debtors (accounts receivable), and inventory on the asset side.
  • Trade creditors (accounts payable), short-term loans, and tax owed on the liability side.

A common mistake is folding long-term items into the calculation, such as a five-year equipment loan or a building’s mortgage. Those belong on the long-term side of the balance sheet, and including them inflates or deflates your working capital picture, leading to decisions based on the wrong number.

How to calculate working capital step by step

Pull your current assets and current liabilities straight from your most recent balance sheet or management accounts, then subtract.

  1. List every current asset: bank balance, outstanding invoices, and stock value.
  2. List every current liability: supplier bills due, short-term loan instalments, and tax owed within twelve months.
  3. Subtract total current liabilities from total current assets.
  4. Compare the result against last month’s figure to spot a trend, not just a snapshot.

Retail example: a shop has 180,000 rand in cash and stock plus 40,000 rand in outstanding customer accounts, against 90,000 rand owed to suppliers and a 20,000 rand short-term loan instalment. Working capital is (180,000 + 40,000) minus (90,000 + 20,000), which equals 110,000 rand, healthy breathing room.

Consulting example: a one-person consultancy has 60,000 rand in the bank and 80,000 rand in unpaid client invoices, against 15,000 rand owed on a business credit card. Working capital is 140,000 minus 15,000, or 125,000 rand, but that figure is only as good as how quickly those invoices actually get paid.

Reading the ratios: current ratio, quick ratio, and the cash conversion cycle

Raw working capital tells you the size of your cushion. Ratios tell you whether that cushion is actually comfortable. The current ratio (current assets divided by current liabilities) sitting roughly between 1.2 and 2.0 is generally considered a comfortable range, according to Statistics South Africa’s working capital analysis; below 1 signals possible trouble meeting short-term obligations. The quick ratio strips out inventory, since stock can be slow to sell, giving a stricter read on immediate liquidity.

Statistic: Academic research on JSE-listed firms links a shorter cash conversion cycle to improved profitability, which is why practitioners treat it as more than an academic exercise.

The cash conversion cycle (CCC) measures how many days pass between paying for inventory and collecting cash from the sale. It combines days sales outstanding (how fast customers pay you), days inventory outstanding (how long stock sits before selling), and days payable outstanding (how long you take to pay suppliers). A shorter CCC generally means cash is tied up for less time; a long one usually points to slow-moving stock or sluggish collections.

  • CCC = DSO + DIO minus DPO.
  • A rising CCC over several months is an early warning sign worth investigating before it becomes a crisis.

Why working capital decides whether the lights stay on

Thin working capital shows up fast: you delay a supplier payment, miss a payroll run, or turn down a good order because you can’t fund the stock. Over time it limits your ability to grow, since every spare rand is already committed to keeping the business running day to day.

Research on JSE-listed firms shows that shortening the cash conversion cycle, especially by improving inventory turnover, positively impacts profitability, according to research on South African retail companies. The flip side matters too: working capital that is too high often means cash is sitting idle in slow-moving stock instead of earning a return elsewhere in the business.

A prioritised checklist to improve your working capital

Start with the fastest wins, then build toward habits that protect you long term.

  1. Invoice the moment a job is done, not at month end, and chase overdue accounts within days rather than weeks. Practical receivables tactics can shorten this cycle noticeably.
  2. Offer electronic payment options so clients have no excuse to delay settling an invoice.
  3. Order stock closer to when you’ll actually sell it, and apply ABC analysis to focus attention on your highest-value items first.
  4. Negotiate longer payment terms with suppliers where the relationship allows it, without straining it.
  5. Run a weekly cash check and build a rolling 13-week cash forecast to catch gaps before they bite, a practice described in guidance on cash flow forecasting.
  6. Turn to short-term finance only when the forecast shows a persistent, structural gap, not a one-off dip, and bring in professional help once shortfalls repeat month after month.

Pro Tip: Track your cash conversion cycle monthly alongside working capital, since the ratio alone won’t tell you whether the problem is stock, collections, or payables.

If invoicing and collections are your weak point, a structured cash-flow management approach can tighten the whole cycle rather than just one piece of it.

Industry norms and the South African working capital picture

Benchmarks differ by sector because the underlying cycle differs: retailers carry heavy inventory, service firms carry heavy receivables, and manufacturers carry both. In South Africa, late payments add another layer of risk. National Treasury reported that national departments owed small businesses a significant amount in unpaid invoices beyond 30 days during the 2021 financial year, creating cash flow pressure for suppliers, according to the MSMEs and Cooperatives Funding Policy, a pressure that ripples straight into supplier cash flow. Clean, up-to-date financials also matter beyond day-to-day survival: they are often required for government-backed working capital support programmes.

When automation and a fractional CFO actually move the needle

When shortfalls keep repeating or your supply chain gets complex enough that nobody can eyeball the numbers anymore, that’s the point to bring in outside help rather than keep patching it manually. A real-time dashboard and a forensic cleanup of messy records shorten the time between spotting a problem and fixing it, because decisions stop waiting on a bookkeeper to catch up at month end.

FAQ

What is working capital in simple words?

Working capital is the money left over after you subtract what your business owes in the next year from what it owns in cash, stock, and receivables in the same period. A positive figure means you can cover short-term bills comfortably; a negative one means cash is tight.

What are three examples of working capital?

Cash in the bank, unpaid customer invoices (accounts receivable), and stock on hand (inventory) are the three most common current assets that make up working capital. They’re weighed against current liabilities like supplier bills and short-term loan instalments to get the final figure.

How do I calculate working capital?

Add up your current assets (cash, receivables, inventory), add up your current liabilities (payables, short-term loans, tax owed), then subtract the second total from the first. For example, a business with 220,000 rand in current assets and 110,000 rand in current liabilities has 110,000 rand in working capital.

What is working capital for dummies?

Think of it as the cushion your business has to pay its bills over the next twelve months without borrowing or selling long-term assets. If current assets outweigh current liabilities, that cushion exists; if not, the business needs a plan to free up cash fast, whether through faster collections, tighter inventory, or professional support from an annual financial statements review.
