When an African small business doubles its revenue, the immediate reaction is celebration. However, rapid revenue growth without a corresponding upgrade in financial oversight is a primary driver of SME insolvency.
In high-inflation environments like Nigeria, expanding sales volume often masks severe cash flow strains, rising procurement leakages, and unsustainable receivable cycles.
When transaction volumes outgrow the founder’s capacity to supervise every transaction, implementing strong finance controls to add when revenue doubles is critical to protecting margins.
Establish transaction approval thresholds
In the early stages of an SME, the founder typically approves every expense. When operations scale and revenue doubles, this centralisation creates operational bottlenecks that slow down business delivery.
The solution is not to hand over unchecked spending power, but to establish a formal delegation of authority matrix. This system sets clear financial limits on who can authorise company funds.
For example, a scaling logistics company might permit operations supervisors to approve fuel purchases up to ₦200,000.
Any expense between ₦200,000 and ₦1 million requires the finance manager’s sign-off, while amounts exceeding ₦1 million must go to the managing director.
To support this, businesses must transition to corporate bank accounts that enforce dual-authorisation. One staff member initiates the payment on the banking portal, and another authorised executive approves it, eliminating single-point vulnerabilities.
Implement three-way matching in procurement
Doubling sales means purchasing more inventory, raw materials, or external services. As supplier invoices multiply, manual verification becomes unreliable, opening the door to duplicate payments and inflated billing.
Scaling SMEs should introduce three-way matching for all major purchases. Under this control, the finance team must verify three distinct documents before releasing any supplier payment.
The first document is the purchase order, which proves the purchase was authorised at an agreed price. The second is the goods received note, proving the business actually received the items in the correct quantity and quality.
The third is the supplier invoice itself. Payments are only processed when the items, quantities, and prices match across all three documents, preventing costly procurement leakages.
Track the cash conversion cycle weekly
A common mistake among scaling founders is confusing accounting profit with cash in the bank. If your revenue doubles because you offered generous credit terms to corporate clients, your bank balance may actually decrease.
This challenge requires close monitoring of the cash conversion cycle, which measures the time it takes to turn cash spent on inventory back into cash received from sales.
The finance team must track trade receivables weekly rather than monthly. Set strict credit limits for customers and automate invoice reminders to reduce the collection period.
For cash-intensive sectors like retail or distribution, daily reconciliation of bank statements with point-of-sale records is vital. This practice catches processing errors, unrecorded transactions, and excess bank charges before they accumulate.
Segregate key financial duties
When a business grows, relying on a single employee to handle all aspects of bookkeeping, cash handling, and bank reconciliation creates significant operational risk.
Segregation of duties ensures that no single individual has total control over any financial transaction from start to finish. This separation makes it difficult for errors or fraud to go unnoticed.
If one employee manages customer invoicing, a different employee should be responsible for recording cash receipts. Similarly, the person who prepares the monthly bank reconciliation should not be an authorised signatory on the bank accounts.
Even in a small team of five to ten people, duties can be divided between administrative staff, an external accountant, and the founder to maintain an effective system of checks and balances.
To begin upgrading your oversight, conduct a review of your current bank accounts today. Identify your monthly transaction volume and configure dual-authorisation controls on your banking portal for all payments above a specific limit.
