For African SMEs executing contract-based projects, winning a major corporate or government tender is often a double-edged sword.
Without a rigorous project cash-flow forecast, a lucrative contract can easily drain a company’s working capital long before the final invoice is paid.
The risk of cash starvation on profitable projects
Many business owners confuse profitability with cash flow. A project may carry a healthy 30% gross margin on paper, but if cash outflows occur in month one and inflows arrive in month four, the business could face insolvency in between.
This tension is acute in markets like Nigeria, where corporate clients often demand 60-day or 90-day payment terms, and high inflation constantly erodes the purchasing power of delayed disbursements.
For example, consider a Lagos-based IT firm that wins a 45 million Naira contract to deploy a software system over three months. The firm must pay developers monthly and buy server hardware upfront, but the client only pays upon completion.
If the firm lacks sufficient cash reserves to cover these operational costs during the deployment phase, the project will stall despite its long-term viability.
Steps to build a project cash flow forecast
To build a resilient forecast, an SME must isolate the project’s cash movements from the company’s general operating accounts. This requires a dedicated worksheet that maps cash timelines.
First, map the project timeline by week or month, listing every expected cash outflow. These include direct project labor, raw materials, subcontractor fees, third-party logistics, and dedicated equipment rentals.
Next, plot the expected cash inflows based on the contract’s payment schedule, not the billing dates. If the contract stipulates payment 30 days after milestone approval, model that inflow with an additional 15-day buffer to account for common administrative delays.
In countries like Nigeria and Kenya, always factor in statutory deductions at source. For instance, the Nigerian Federal Inland Revenue Service requires corporate clients to deduct Withholding Tax of up to 10% on contracts before paying the balance.
This means the actual cash entering the bank account will be lower than the invoiced amount, a variance that must be reflected in the forecast to avoid overstating inflows.
Common forecasting mistakes to avoid
The most frequent mistake SME owners make is relying on mobilization fees to fund general business overheads. Using one project’s advance payment to settle another project’s debts creates a dangerous deficit cycle.
Another error is ignoring the cost of currency volatility when sourcing imported inputs. If a project requires importing specialized machinery, any depreciation of the local currency between the bid and purchase dates will inflate cash outflows.
Additionally, many small business owners fail to negotiate milestone-based payments. Accepting a single lump-sum payment upon completion, rather than phased disbursements, significantly increases the cash-flow burden on the contractor.
Practical steps to protect your cash flow
To safeguard your operations, always demand a mobilization fee or an upfront deposit of at least 20% to 30% to cover initial setup and material procurement costs.
If a corporate client refuses upfront payments, present your completed project cash-flow forecast to your bank to secure a dedicated invoice discounting facility or a project finance line before commencing work.
