In this article Why revenue growth can consume more cash than it generates A 5-question test to find out whether you have hit your ceiling The link between the founder-technician profile and cash leaks A quantified client case: +6 points of margin and a cash buffer of FCFA 1.5 million per month The levers: internal control (COSO), a 13-week cash flow forecast, independent external review

 

 

According to the mid-term evaluation of the AfDB’s Jobs for Youth in Africa strategy (IDEV, 2023), the average start-up failure rate in Africa reached 54% in 2020. A World Bank study of more than 14,000 small firms in 12 developing countries found that half had ceased operating after roughly six years (Paffhausen and McKenzie, 2017). In our practice, lack of structure, managerial skills and liquidity are among the most frequent causes. Yet for many of these companies, in their early years, the order book is overflowing, teams are growing and the customer portfolio keeps expanding. But despite this, at every month-end the owner faces the same stressful trade-off: which supplier to pay first? How to cover payroll? Why does cash remain tight while revenue reaches record highs?

 

Most of them face the same paradox: growth on the surface, financial and operational disorganization behind the scenes.

Drawing on the Law of the Lid, this article offers an analytical grid of the bottlenecks that cap cash flow. It shows how decision-making habits, lack of delegation and rigid information flows weigh directly on working capital requirements (WCR).

 

 

The Law of the Lid in one sentence In The 21 Irrefutable Laws of Leadership (1998), American author and speaker John C. Maxwell states that a person’s leadership ability determines the level of effectiveness of their organization. Applied to financial management, this leads to one conclusion: the lid on your cash flow is not your market, it is your organization.

 

Strategic insight Beyond a certain level of activity, each additional franc of revenue no longer creates value: it is diluted in late payments, administrative duplication and firefighting.

 

 

Most companies are born from flawless technical mastery: knowing how to sell, build, negotiate or deliver a complex service. Michael Gerber, in The E-Myth Revisited (1995), calls this profile the “technician” and warns of its founding trap: believing that mastering a trade is enough to run the company that practices it.

 

The skills needed to create a business are not those needed to scale it. The owner must undergo a managerial mutation: move from doing to designing (designing teams, introducing procedures, structuring information flows).

 

CREATION PHASE The founder does and approves everything.

➜

AUTONOMY CRISIS Bottleneck: centralization becomes a blocker.

➜

STRUCTURING PHASE The founder designs rules and delegates.

 

This transition is unavoidable. In Larry Greiner’s growth model (1972), every company goes through a crisis of autonomy when a single decision-maker can no longer supervise everything. In SMEs, this threshold often falls between 15 and 40 employees (indicative benchmark). Teams need room to act, but management keeps centralizing everything.

At 5 employees, centralized approval works. At 30, it becomes a major bottleneck in the sense of Eliyahu Goldratt’s Theory of Constraints (1984): the company’s overall capacity is capped by the processing capacity of its narrowest link, the owner.

 

How the bottleneck shows up in practice

Symptom	Description
Supplier payment delays	Invoices pile up awaiting sign-off, causing penalties, lost discounts and suspended deliveries.
Lost opportunities	Sales staff lack the delegated authority to close quickly.
Little initiative	Teams wait for the owner’s approval for every action, even routine ones.
Financial opacity	Management information lives in the owner’s memory or in an isolated spreadsheet only they can handle.

 

In this context, speeding up sales does not help: it increases pressure on an already saturated decision structure. An SME that only works when its founder is present carries a major risk of operational breakdown.

 

These reflexes are not faults: they are the qualities that made the founder successful, applied to an organisation that has changed size. But they have a cost, and it shows in the accounts.

 

Key takeaways The skills that create a company are not those that grow it: you must move from doing to designing. Beyond a certain size, centralised approval becomes a bottleneck. Selling more makes the problem worse until the decision structure is redesigned.

 

 

The limits of leadership are not merely theoretical: they can be read directly in the balance sheet and income statement. The table below links each natural reflex of the founder-technician to the dysfunction it produces, then to the resulting cash leak.

 

Impact matrix: from managerial reflex to cash flow risk

Founder-technician reflex	Organizational dysfunction	Direct cash flow impact	Key indicator (KPI)
Approving everything personally	Held-up decisions, single sign-off	Late-payment penalties, lost supplier discounts, supply disruptions	Number of invoices awaiting sign-off (> 48 h)
Deciding everything alone	Passive teams with little initiative	Missed sales opportunities, quotes and orders stuck	Average time to approve a routine decision
Prioritizing sales volume over costs	No cost accounting or product costing	Cross-subsidy: one activity absorbs cash generated by the others	Gross margin and net cash flow per product line
Negotiating prices, neglecting payment terms	No customer credit policy, no negotiation of terms	Structural gap: purchases are financed before customers pay	Gap between DPO (supplier days) and DSO (customer days)
Treating accounting as a tax obligation	Late, purely compliance-driven bookkeeping	Blind decisions, no working capital control, tax adjustments	Monthly close time (target: before D+10)
Steering by the instant bank balance	No forward-looking cash tools	Unnegotiated overdrafts, high bank charges, insolvency risk	Rolling 13-week projected balance
Invoicing opportunistically	Irregular invoicing, informal reminders	Artificially longer customer credit, doubtful receivables	DSO (Days Sales Outstanding) and overdue receivables ratio

 

Reactive accounting or management accounting? Many SMEs keep their books “to pay taxes” and satisfy the bank. Management accounting does the opposite: it anticipates and answers questions such as “will I have enough cash in 60 days?” or “which customers and products cost me more than they earn?”.

The financial impact on Working Capital Requirements (WCR)

A poorly managed invoicing cycle needlessly ties up essential resources.

 

📐 Worked example Take an SME with annual revenue of FCFA 65 million, about FCFA 1.25 million per week. Cutting average customer collection time (DSO) by just 14 days immediately releases FCFA 2.5 million of cash, with no external financing and without selling one more product. Fast invoicing and structured reminders ➜ DSO reduced by 14 days ➜ + FCFA 2,500,000 of immediate cash   The same logic applies on the supplier side: with FCFA 45 million of annual purchases (about FCFA 123,000 per day), extending supplier credit from 30 to 45 days releases nearly FCFA 1.85 million.

 

For SMEs working with large accounts or public contracts, where payment terms are structurally long, mastering invoicing and collection processes becomes a survival condition.

 

⚖ The legal risk: cessation of payments under OHADA law Under the OHADA Uniform Act organizing collective proceedings for wiping off debts (OHADA, 2015), cessation of payments occurs when a company can no longer meet its due liabilities with its available assets. Many SMEs that look profitable on paper end up in collective proceedings solely for lack of forward-looking liquidity management.

 

🏭 CASE STUDY

Client case study: from forced cash to managed cash

+6 pts of overall gross margin

30 → 45 d of supplier credit

≥ 1.5 M FCFA minimum cash per month

90 days to roll out the system

 

Sector	Commercial equipment distribution (Central Africa)
Size	15 employees · FCFA 65 million annual revenue
Initial diagnosis	Steady revenue growth, but systematic liquidity crises at month-end (unable to pay salaries without a bank overdraft).
Causes identified	1. No cost accounting. A flagship product, accounting for 60% of revenue, was absorbing the cash of the other product lines, without its real profitability (including sourcing and storage costs) being measured. 2. Excessive decision centralization. The owner approved every expense. Teams took no initiative and did not follow up collections rigorously.
Action plan (90 days)	Diagnosis, then a simplified cost accounting system to revise the price grid and product catalogue. Annual forecast and a rolling 13-week cash flow plan. Renegotiation of supplier terms: credit extended from 30 to 45 days, while customers paid at 30 days. Procedures manual setting delegation thresholds, automated customer reminders and user training.
Measured results	+6 points of overall gross margin through product catalogue adjustment and a better cost price structure. Minimum cash of at least FCFA 1.5 million per month (about 8 days of revenue) to absorb the unexpected. Elimination of bank charges and unauthorized overdraft fees.

 

Key takeaways Each reflex of the founder-technician translates into a measurable cash leak. A simple indicator can detect each leak before it becomes a crisis. Management accounting anticipates; reactive accounting merely records.

 

 

Raising the lid means replacing the owner’s intuitive way of working with an organization framed by rules and procedures: moving the company from “dependent on one person” to “dependent on rules”.

3.1 Building proportionate internal control (COSO framework)

The COSO framework (Committee of Sponsoring Organizations of the Treadway Commission, 2013) defines internal control as a process carried out by the board, management and staff, designed to provide reasonable assurance regarding the achievement of objectives in operational performance, reporting reliability and regulatory compliance. Assurance is “reasonable”, never absolute: the system must remain proportionate to the size and risks of the company.

 

COSO FRAMEWORK · THREE CATEGORIES OF OBJECTIVES
OPERATIONS Effectiveness and efficiency	REPORTING Reliable, up-to-date information	COMPLIANCE Adherence to laws and standards

 

For an SME, the goal is not to create bureaucracy but to apply four key COSO principles:

COSO principle	Content	Application in an SME
Principle 3	Establish structures, reporting lines, authorities and responsibilities	Org chart, job descriptions, authority matrix
Principle 12	Deploy controls through formalized policies and procedures	Procedures manual covering the processes that concentrate cash
Principle 13	Use relevant, quality information to steer the business	Monthly dashboard, 13-week cash flow forecast
Principle 16	Conduct ongoing and periodic evaluations of the system	Monthly reconciliations, annual external review

 

The 5 golden rules of internal control in an SME

 

#	Rule	In practice
1	Segregation of duties	In line with Donald Cressey’s work on fraud risk factors (the “fraud triangle”, 1953), the person who places the order must be neither the one who receives the goods nor the one who makes the payment.
2	Formal delegation thresholds	Set up an authority matrix stating who may commit spending according to amount, with a formally designated deputy.
3	Three-way matching	Systematically match the purchase order, delivery note and invoice before any payment is released.
4	Independent control of cash accounts	Perform a monthly bank reconciliation by a person independent of cash handling and payments.
5	Mapping of key procedures	Document in writing the 5 processes critical to cash: purchase-to-pay, order-to-cash, collections, payroll and cash handling.

 

These rules directly address the lack of initiative observed in our client case: when approval thresholds are written down, teams know what they can decide on their own, and the owner stops being the bottleneck.

3.2 Automating and structuring cash flow management

An effective internal control system relies on forward-looking information tools. Three mechanisms are essential.

ROLLING 13-WEEK CASH FLOW FORECAST (EXAMPLE)
CASH IN Invoices issued + customer payment schedules	CASH OUT Fixed costs + suppliers + payroll
PROJECTED NET BALANCE · Early warning of cash shortfalls

 

1. The rolling 13-week cash flow forecast. It replaces reading the instant bank balance with a dynamic projection of cash inflows and outflows, and identifies cash gaps 2 to 3 months before they occur.

2. A concise forward-looking dashboard. Inspired by Kaplan and Norton’s Balanced Scorecard (1992), it gathers 6 to 8 action indicators, chosen to steer the business rather than describe it.

3. Digitised collection processes. Automatic alerts as soon as invoices fall due, and approval workflows for expenses.

 

Dashboard indicators ▪  Available and projected cash balance ▪  Cash conversion cycle (Richards and Laughlin, 1980) ▪  DSO (average customer payment time) and DPO (average supplier payment time) ▪  Monthly fixed costs ▪  Volume and age of unpaid overdue receivables ▪  Margin by activity or product line

 

Management or online accounting software is often enough. What matters is the regularity of information, not its sophistication. An alert that nobody is responsible for handling protects nothing.

3.3 Strategic support and outsourcing of support functions

An SME does not always have the resources to hire a full-time finance director or internal auditor. Outsourcing these skills provides the expertise while keeping fixed costs under control. Under the Institute of Internal Auditors’ Three Lines Model (IIA, 2020), an independent expert plays the role of the third line, independent assurance, which an SME cannot build in-house. This brings:

 

Contribution	Description
Accounting and tax compliance	Books kept in line with the revised SYSCOHADA framework (OHADA, 2017), ensuring the fair presentation of financial statements to tax authorities and banks.
Process security	An impartial assessment of the internal control chain and early detection of cash leaks.
Forward-looking vision	Support for the owner in steering financial performance and preparing financing applications.

 

Key takeaways Internal control is proportionate: few rules, but written down and applied. The 13-week cash flow forecast replaces reading today’s bank balance. Independent external review delivers the reliability that banks and investors expect.

 

 

The limit to an SME’s development is rarely an external market constraint. Very often it is a corollary of the leadership lid. In most cases it is an internal organisational lid, shaped directly by the decision-making and control habits set by management.

Structuring internal control and managing cash flow prospectively means accepting to raise your own lid, giving yourself the means to unlock your company’s growth potential and secure its longevity. The good news: it is the easiest limit to raise, because it depends on you.

 

What is the Law of the Lid in business management?

Formulated by John C. Maxwell, it holds that a person’s leadership ability sets the maximum level of effectiveness of their organisation. Applied to finance, it means an SME’s cash flow ceiling depends on its decision-making, delegation and control habits more than on its market.

Why does an SME with fast revenue growth run into cash flow stress?

Business growth automatically increases Working Capital Requirements (WCR): larger inventories, higher customer receivables and higher operating costs. If collection times are not controlled and approval processes remain centralized, the company consumes more cash than it generates, which can lead to a liquidity crisis.

What does an internal control system suited to an SME look like?

It is a set of pragmatic, proportionate rules (segregation of duties, delegation of authority matrices, bank and document reconciliation procedures) designed to safeguard assets, prevent errors and fraud, and ensure reliable financial information without weighing down operations.

When is it relevant to use an outsourced CFO or external accounting review?

External support becomes a priority when the owner spends excessive time resolving administrative and financial dysfunctions, when financial statements are repeatedly late, or ahead of a fundraising or bank credit negotiation.

💡 QUICK DIAGNOSTIC

Have you hit your cash flow lid? A 2-minute test

 

An SME’s lid builds up gradually. Symptoms appear in isolation: a payment approved three days late, a customer reminder neglected, a management report delivered past deadline. By getting used to them, the owner ends up normalizing dysfunctions that actually signal a break in organizational capacity.

 

The lid is reached when sales growth no longer translates into more available cash.

 

Answer Yes or No. A “Yes” applies whenever the situation is recurrent.

#	Question	Yes	No
1	Decision dependency. Do supplier payments and purchase orders systematically wait for your approval or signature?	☐	☐
2	No forward visibility. Are you unable to state your net cash balance precisely 8 to 13 weeks ahead?	☐	☐
3	Broken collection chain. Are customer invoices issued irregularly, with reminders that depend on individual goodwill?	☐	☐
4	Late financial information. Do your financial statements and monthly accounts reach you several months late?	☐	☐
5	Operational hyper-centralisation. Does activity slow down noticeably as soon as you are away from the office?	☐	☐

 

“Yes” answers	Reading	What it means
0 to 1	Organisation under control	Risk is limited. Stay vigilant during phases of rapid growth.
2 to 3	Lid reached or imminent	Your internal organisation is already acting as a brake on your cash flow and exposes the company to illiquidity risk.
4 to 5	Lid exceeded	The risk of cash stress is high. A rapid diagnostic is recommended before the situation is forced on you.
