Managing cash flow: A survival guide for Lagos SMEs

By Joy Essien

For small and medium-sized enterprises (SMEs), staying in business in Nigeria’s bustling commercial centres, particularly Lagos and Abuja, requires more than generating sales. Business owners must contend with fluctuating inventory replacement costs, foreign exchange volatility, delayed client payments and rising logistics expenses, all of which can put pressure on available cash.

A business may be profitable on paper and still struggle to pay salaries, replenish stock or meet its daily obligations. The difference between surviving a difficult month and shutting down often lies in how well the business manages its cash flow.

This guide explores the cash flow challenges facing Nigerian SMEs and offers practical strategies for managing working capital, closing payment gaps and building a financial buffer against unexpected expenses.

1. The Lagos SME cash flow reality check

Cash flow crises rarely occur simply because a business is unprofitable on paper. More often, they arise when the timing of cash outflows does not match the timing of cash inflows.

Key pressure points for Nigerian service providers, retailers and commercial vendors include:

• The 30-to-90-day invoice lag: Corporate clients and institutional buyers often operate on extended credit terms, leaving working capital tied up in unpaid invoices while operational expenses, including salaries, fuel or diesel, rent and internet subscriptions, must still be paid promptly.
• Input cost volatility: Frequent changes in logistics, transport and raw material prices mean that last month’s profit margin can easily be wiped out by this month’s restocking bill.
• Client advance vulnerability: Relying entirely on final payment upon project completion exposes a business to sudden changes in project scope, additional costs and administrative payment delays.

Step 1: Calculate your true monthly burn rate

Many business owners underestimate their burn rate because they count only the direct costs of goods sold (COGS). To establish how long your available cash can sustain operations, calculate your total monthly cash outflow.

The fixed baseline: Rent, internet, software subscriptions and baseline staff salaries.

The variable shockers: Average monthly expenditure on diesel or petrol, generator maintenance, logistics, and government levies or dues.

Example: If your fixed overheads and baseline operating expenses total ₦2,500,000 a month, that is your baseline cash requirement every 30 days.

Step 2: Map your working capital gap (the inflow-versus-outflow mismatch)

Examine your cash position alongside your accounts receivable (AR) to understand the difference between money available now and money owed to your business.

• Cash in the bank: How much money is immediately available? For example, ₦3,500,000.
• Trapped cash (AR): How much money have you earned but not yet received because it is sitting in a client’s 30-to-60-day payment queue? For example, ₦4,000,000.
• The danger zone: Remember that trapped cash cannot buy diesel or pay salaries today. If you have ₦3,500,000 in the bank and a monthly burn rate of ₦2,500,000, your actual cash runway is just 1.4 months, even if clients technically owe you millions more.

Step 3: Take practical steps to close the gap

Enforce milestone billing: Never execute an entire project or fulfil a large supply order on the basis of a single invoice payable at the end of the month. Split payments into agreed instalments tied to specific milestones.

Offer a 2% prompt-payment discount: Encourage corporate clients to pay within seven days rather than 30 by offering a small discount. The cost of the discount may be lower than the interest on a high-cost, short-term loan needed to bridge the cash flow gap.

Audit receivables weekly: Treat unpaid invoices as a priority for collection. Designate a specific morning each week to follow up on outstanding payments and resolve delays.

3. Four-step survival action plan

To protect liquidity and build resilience against delayed payments and sudden increases in supply costs, implement the following framework.

1. Restructure payment terms (the 50/40/10 rule): Stop accepting projects or supply orders entirely on credit or with only token deposits. For suitable client projects and supply orders, negotiate a 50% advance paymentbefore work begins, 40% upon delivery of an agreed milestone, and the final 10% upon sign-off. Adapt the arrangement to the nature of the contract and the client’s payment capacity.
2. Institute strict credit control and ageing reports: Review accounts receivable weekly. Categorise unpaid invoices according to their age, including those outstanding for 30, 60 and 90 days or more. Set up automatic payment reminders and suspend further service delivery to accounts that exceed agreed credit limits, subject to contractual obligations.
3. Build a 90-day operating reserve: Keep business and personal finances entirely separate. Transfer a fixed percentage, such as 5% to 10% of each cash inflow, into a separate business reserve account. Build towards a reserve capable of covering three months of essential operating expenses, while accounting for taxes and emergencies such as sudden fuel price increases or generator repairs.
4. Negotiate flexible supplier terms: Rather than paying cash upfront for every restocking order, cultivate relationships with key distributors and negotiate a 15-to-30-day payment window based on a consistent purchase history. This can preserve immediate cash for payroll and overheads, provided the agreed terms are commercially viable and the business can meet its obligations when due.

Important points to note

• The high cost of backup power and infrastructure: Unlike businesses operating in economies with reliable public utilities, Nigerian SMEs often face substantial and unpredictable expenses associated with diesel or petrol, inverter maintenance and backup internet subscriptions. Operating costs can rise sharply following fuel price adjustments or currency fluctuations that affect the cost of imported generator parts.
• The multiple-tax and levy landscape: Beyond corporate income tax and value-added tax (VAT), businesses may have to contend with applicable state and local government rates, signage fees, sanitation levies and association dues. Failing to include these irregular or lump-sum payments in cash flow forecasts can trigger unexpected month-end shortages. Business owners should identify their applicable statutory obligations, verify demands and budget for legitimate charges.
• Informal banking and foreign exchange realities: Sourcing foreign exchange for imported stock, software licences or raw materials can expose SMEs to exchange-rate volatility and transaction delays. A business may appear profitable at its current naira prices, only to discover that replacing imported inventory costs significantly more when the supplier’s pro forma invoice falls due.
• The relationship-first credit trap: In close-knit commercial networks, including markets in Alaba and Idumota and corporate circles on Victoria Island and in Ikeja, business relationships are often built on personal trust. Owners may hesitate to pursue overdue payments firmly from influential clients or long-standing partners for fear of damaging those relationships. The result can be a growing pile of uncollected receivables and persistent cash flow problems.

Final thoughts: Make cash flow a business priority

For Lagos SMEs, survival depends not merely on how much money comes in, but on how much is available when obligations fall due. Strong sales, impressive contracts and a long list of debtors mean little if the business cannot pay its workers, replenish stock or keep the lights on.

Business owners must therefore make cash flow management a routine discipline. Forecast inflows and outflows, invoice promptly, follow up on overdue payments, negotiate realistic payment terms and build an operating reserve gradually. Above all, distinguish money already earned from money actually received.

Profitability may keep a business attractive on paper, but healthy cash flow keeps it operating in the real world.
