Cash Flow Gap: How to Purchase Inventory When Funds Are "Tied Up" in Accounts Receivable

Cash flow gaps are the cause of bankruptcy in 82% of cases where small and medium-sized businesses close, even if the company remains profitable “on paper.” This paradox arises instantly: suppliers demand payment today, the tax authorities won’t wait, and payment for shipped goods won’t arrive for another two weeks.

Financial stability depends not on the amount listed in the “Net Profit” column, but on management’s ability to synchronize incoming and outgoing transactions. In this article, we explain the mechanics of this phenomenon and offer proven tools for seamless procurement when equity capital is temporarily unavailable.

What Is a Cash Gap and How Does It Occur?

A cash gap is a temporary shortage of funds in a company’s accounts needed to cover mandatory current expenses, provided that the business is generally profitable. This situation is characterized by a time lag between receiving payments from customers and the need to pay suppliers. The main pitfall lies in the illusion of security: a manager sees signed work completion certificates or invoices, considers this money “theirs,” but is physically unable to use it to purchase a new batch of goods or pay salaries.

Financial management distinguishes between the concepts of insolvency and a cash gap. Insolvency indicates systemic unprofitability, where liabilities exceed assets. A cash gap arises when assets (accounts receivable) exceed liabilities but have low liquidity at a specific point in time. Money is converted into inventory, inventory into accounts receivable, and only later back into money. Any delay in the “inventory-to-money” conversion process halts the operating cycle.

The mechanics behind the occurrence of a cash flow gap are most often linked to errors in planning the payment schedule or force majeure circumstances on the part of partners. A typical scenario looks like this: a company invests all its available funds in purchasing seasonal merchandise, ships it to a wholesale customer with a 45-day payment deferral, and 30 days later, the due dates for VAT and warehouse rent arrive. The account is empty, even though the deal yielded a potential profit of 30%.

The main causes of a liquidity shortage:

1. Discrepancy in payment terms. The company pays suppliers in advance but offers customers payment terms.
2. Seasonal fluctuations. A sharp increase in demand requires an increase in inventory, which “ties up” working capital long before revenue is received.
3. Investments from operating activities. Using operating cash to purchase fixed assets instead of long-term financing.
4. Overdue accounts receivable. Customers are breaking their agreements, and the business has no contingency plan.
5. Scaling a business. Rapid growth requires increased spending on personnel and logistics, which outpaces revenue from new contracts.

Failure to manage these factors turns temporary cash flow gaps into a chronic problem that hinders growth. Understanding the nature of this phenomenon allows us to move from a haphazard search for funds to systematic forecasting.

The Impact of a Cash Flow Gap on Businesses

The main risk lies in the suspension of operations: the inability to purchase goods leads to a shortage of products and the loss of customers. The business loses market share, which is immediately taken over by competitors with better liquidity.

Economic consequences directly affect profit margins. The urgent need for cash forces businesses to take out expensive loans or sell accounts receivable at a significant discount. Suppliers, having not received payment on time, cancel individual discounts, switch the company to full prepayment, or halt shipments. Losing the status of a reliable partner costs more than the interest on borrowed funds.

Analysis of the Impact of Cash Flow Gaps on Business Processes:

The hardest blow falls on the procurement department, which is losing its flexibility:

• the inability to take advantage of suppliers’ promotional offers;
• reducing inventory levels to a critical minimum (risk of being out of stock);
• deterioration of logistics conditions due to the inability to pay for priority delivery;
• the failure to launch new products due to a lack of funds for the first batch;
• tension in relations with suppliers who require letters of guarantee.

Addressing these consequences requires significantly more resources than preventive measures. That is why cash flows must be monitored constantly.

How to Calculate and Forecast a Cash Gap

Forecasting financial shortfalls is based on building a cash flow forecast model. Balancing the cash account for a future period is a mathematical problem that requires accurate input data. The basic principle of the calculation involves comparing the available cash balance with planned payments for each specific date.

The cash flow gap forecasting algorithm involves analyzing three key metrics: accounts payable turnover, accounts receivable turnover, and inventory turnover. The financial cycle formula is: cycle = Days of inventory + Days of accounts receivable — Days of accounts payable. A positive cycle value indicates the number of days during which the business requires external financing.

A basic algorithm for calculating the cash gap for small businesses:

1. Digitizing account balances. Recording the actual amounts of money in all accounts and in the cash register.
2. Register of Mandatory Payments. List of payments with fixed due dates (rent, taxes, loans, salaries).
3. Variable Expense Plan. Forecast of payments to suppliers, logistics, and marketing.
4. Revenue Schedule. A realistic forecast of customer payments (taking delays into account).
5. Balance Sheet. Calculating the daily balance. If the balance becomes negative on any given day, that is the point of a cash gap.
6. Scenario Analysis. Calculation of the pessimistic scenario (customers delayed payment by 5 days).

Example of a simplified payment schedule:

In the example given, a shortfall of 15,000 UAH arises on February 10. The manager has time to make a decision: to postpone the purchase or to negotiate a partial payment for the rent.

Monthly monitoring of financial health should include a review of the following indicators:

• the current status of the accounts receivable ledger and the payment terms;
• the percentage of overdue payments from customers (the growth trend is a warning sign);
• the ratio of current liabilities to the most liquid assets;
• average daily burn rate and how many days the current cash balance will last;
• the deviation of actual results from the plan for the previous month, to adjust the accuracy of forecasts;
• the status of key agreements that account for the lion’s share of revenue.

Implementing regular cost forecasting allows you to turn finances into a manageable navigation system for your business.

Strategies for Bridging the Cash Flow Gap: How to Make Purchases Without “Tied-Up” Funds

Overcoming the cash flow gap requires a comprehensive approach that combines tactical measures with strategic changes in capital management. The main goal is to free up resources and ensure continuity of supply.

An effective liquidity management strategy includes the following steps:

1. Segmentation of accounts receivable. Classification of receivables by due date and risk. Implementation of an automated reminder system for customers 3 days before and on the due date.
2. Speed Discount. Offer customers a 2–5% discount for paying their bill within 3 days instead of the standard 30. This is cheaper than the cost of external financing.
3. Negotiations with existing suppliers. An official request to split a large payment into installments (for example, 30% now, 70% in two weeks). The key to success is transparency regarding the reasons and guarantees.
4. Inventory Management. Holding a promotional sale of slow-moving inventory to quickly free up cash, even with a minimal margin.
5. Creating a reserve fund. Set aside 3–5% of each incoming payment in a separate savings account for a rainy day.
6. Prioritizing payments. Categorizing bills as “critical” (without which the business will grind to a halt), “important” (penalties apply, but arrangements can be made), and “desirable” (can be postponed).
7. Changes to contract terms. Gradually transitioning new customers to partial prepayment or shortening payment deferral periods.
8. Use of payment instruments. Use of corporate credit cards with a grace period for small purchases.

Paying for Purchases in Installments as a Way to Keep Cash Flow Moving

A separate and highly effective strategy for maintaining procurement momentum is the use of external financial instruments that allow you to receive goods now and pay later. This relieves pressure on working capital during periods of peak payments. Modern solutions, such as BNPL (Buy Now, Pay Later) for B2B, are emerging as an alternative to complex bank loans and factoring.

eDilo is an online installment payment service for businesses that allows them to purchase goods and services with deferred payment, breaking the total amount down into convenient installments. The service works simply: the supplier receives the full amount immediately, and the buyer repays the service according to a schedule. This allows businesses to restock inventory or upgrade equipment exactly when they need to, without waiting for customers to pay their invoices. The application process is fully digital: the business owner selects a product from an eDilo partner, submits a brief application, receives a decision within 30 minutes, and signs an electronic contract.

If your business’s cash flow is affected by seasonality, consider integrating eDilo as your standard procurement tool. This will help you turn the stress of cash shortages into a planned financial management process.
