One of the most critical — and often overlooked — components of managing your working capital is your ability to manage your debtors.
For SMEs and growth businesses, revenue means very little until it converts into cash. You can have a strong order book, healthy margins on paper, and a growing client base — but if your debtors are slow-paying or defaulting, your working capital cycle tightens quickly. And when working capital tightens, growth stalls.
Recently, Kredcor shared an excellent and practical checklist unpacking the true cost of bad debt on South African SMEs. Their insights deserve attention — particularly for business owners who want to protect their cash flow and strengthen their balance sheets.
Below, we unpack some of the most important takeaways — and what you can do about them right now.
The true cost of bad debt – beyond the invoice
This is where most business owners get the maths wrong.
If a client owes you R50,000 and doesn’t pay, the cost of that bad debt is not R50,000. It is substantially more.
To recover R50,000 in lost revenue, your business has to generate additional sales. The amount of new sales required depends entirely on your net profit margin.
The rule of thumb:
- If your net profit margin is 10%, you need R500,000 in new sales just to replace R50,000 in bad debt.
- If your margin is 5%, you need R1,000,000 in new sales to cover the same loss.
This is what KredKor rightly highlights as the replacement cost of bad debt — the part most SMEs fail to calculate.
Your team, your time, your overheads, your raw materials — all expended on goods or services you were never paid for. From a working capital perspective, that is capital permanently removed from your operating cycle.
The hidden operational costs nobody talks about
Bad debt does not simply sit on your debtors’ ledger. It drags along a tail of operational costs that quietly erode profitability.
KredKor’s experience working with SMEs across Gauteng, the Western Cape, and KwaZulu-Natal shows that these hidden costs can be significant:
- Staff time spent on collections. Every hour your credit controller or bookkeeper spends chasing overdue invoices is time diverted from productive work.
- Interest and financing costs. Drawing on an overdraft because customers have not paid means you are paying interest on money that is already yours.
| - Legal and administration costs. Demand letters, attorney consultations and court processes all carry costs before a single rand is recovered.
- Write-off administration. The accounting and tax treatment of bad debt also consumes time and resources.
When measured properly, these hidden costs can easily double the true cost of bad debt relative to the original invoice value.
For SMEs operating on tight margins, that erosion of working capital can be devastating.
How bad debt destroys cash flow and growth
Cash flow is the lifeblood of any SME.
We have seen businesses with strong revenue pipelines come within weeks of collapse — not because they lacked demand, but because they could not convert sales into cash quickly enough.
The knock-on effects are severe:
- Supplier payments are delayed, damaging relationships and credit terms.
- Staff wages become harder to meet on time.
- Growth investments – new equipment, additional staff, marketing – are postponed.
- Business owners absorb personal financial stress, impacting decision-making.
From a working capital advisory perspective, slow-paying debtors represent one of the most significant threats to business sustainability. It is not simply a finance department issue – it affects every corner of the organisation.
The reputational cost of carrying bad debt
Another important insight KredKor raises is the reputational dimension.
When your business becomes cash-strapped due to unpaid debtors, operational compromises often follow — slower delivery, reduced service levels, strained supplier relationships.
Suppliers who are not paid on time may begin to view your business as a credit risk. Credit terms may tighten. Your own access to working capital becomes constrained.
Bad debt, therefore, does not just weaken your balance sheet — it weakens your standing in the market.
Actionable steps to reduce the cost of bad debt
The good news is that bad debt is not inevitable. There are practical steps SMEs can implement immediately:
- Conduct credit checks before extending credit. Never extend credit without a verified business credit report.
- Set clear, written credit terms. Credit agreements must be in writing, signed, and enforceable. Verbal arrangements are extremely difficult to recover against.
- Act early on overdue accounts. Recovery rates drop dramatically as accounts age. Escalate at 30 days – not 90.
- Implement a formal credit management policy. A written, consistently applied credit policy creates discipline and accountability.
- Understand your legal obligations. Credit extension and recovery in South Africa are governed by the National Credit Act. Non-compliance can expose your business to legal risk when attempting recovery.
- Separate collections from sales. Allowing sales teams to manage overdue accounts often creates conflicts of interest. Assign collections to a dedicated credit controller or outsource to specialists.
Why this matters for your Working Capital strategy
At Decusatio Working Capital Solutions, we view debtor management as one of the three pillars of working capital optimisation — alongside inventory and payables management.
You cannot scale a business sustainably if your cash conversion cycle is broken.
The insights shared by KredKor are a timely reminder that bad debt is not merely an accounting adjustment at year-end. It is a strategic risk that impacts liquidity, growth capacity, reputation and resilience.
If you are serious about protecting your working capital, start by asking a simple question:
Are your debtors working for you – or against you?
Now is the time to find out.
