Customer Concentration: Preparing a Financing Request

A large customer can keep a production line busy while making the business unusually dependent on one payment calendar. Before requesting capital, it helps to show both sides: the value of that relationship and what happens if an expected receipt arrives late.

Customer concentration matters in business financing because a meaningful share of sales or unpaid invoices may depend on a small number of buyers. A useful financing file explains the exposure with dated numbers, payment evidence, and a workable cash plan.

Calculate sales and receivables concentration separately

Start with two reports that answer different questions.

Sales concentration measures a customer's share of revenue over a stated period. Divide revenue from that customer by total revenue for the same business, period, and accounting basis. Show the latest completed year and a recent comparable period if the mix has changed.

Receivables concentration measures a customer's share of outstanding receivables on a particular date. Divide that customer's outstanding balance by the total receivables balance on the same basis. Keep the date, treatment of credits, and reconciliation visible.

Consider a hypothetical distributor with $300,000 of sales in September, including $90,000 to Buyer A. Buyer A represents 30% of that month's sales. At September 30, Buyer A owes $180,000 of the distributor's $450,000 total receivables: 40% of outstanding receivables.

Those percentages need not match. Different payment terms, invoice timing, or overdue amounts could explain the difference. The next step is to identify the reason from the records, not assume that the larger percentage proves a collection problem.

Use our receivables aging guide to organize the underlying invoice detail.

Identify the buyer behind each account

An accounting system may show separate customer codes for branches, locations, or divisions of the same buyer. Prepare a list that identifies the invoiced legal entities and explains known connections. Let the reviewing provider confirm how its concentration rules group those accounts.

Keep the original customer-level detail so the grouped total can be checked. Simply splitting one relationship into more rows does not create more independent sources of payment.

Also flag a broader dependency, such as several customers serving the same end market. The OCC's receivables-financing handbook discusses both large-account exposure and concentrations within an industry. This is bank supervisory guidance, not a Sussex Capital eligibility policy.

Explain the relationship with evidence

A familiar customer name is useful context, but it is not a payment record. Assemble a concise summary of the largest relationships, with supporting documents available for review:

• Trading history: How long the relationship has existed and whether sales are recurring or tied to a particular project.
• Payment behavior: Contractual terms, actual collection dates, and any recent change in payment speed.
• Current invoices: Amounts outstanding, due dates, disputes, credits, and documented collection updates.
• Future business: Signed orders or contracts, their duration, and any relevant cancellation or renewal provisions.
• Operational dependence: Staff, inventory, or capacity committed to that customer and the time needed to redirect them.

Distinguish signed work from a sales forecast. Do not treat a customer's expected payment date as money already received.

J.P. Morgan's credit-management guidance emphasizes reviewing customer creditworthiness and monitoring payment patterns, particularly when a major customer creates a substantial exposure.

If a large buyer is central to your capital request, apply with Sussex Capital and explain the relationship, the funding purpose, and which records are ready. Identify any information still awaiting confirmation.

Test a delayed receipt against actual bills

Return to the hypothetical distributor. Assume its coming-week cash plan includes:

• Opening unrestricted cash: $40,000.
• Expected receipts from customers other than Buyer A: $50,000.
• One expected receipt from Buyer A: $60,000.
• Scheduled cash outflows: $100,000.

If all receipts arrive as planned, closing cash is $50,000: $40,000 + $50,000 + $60,000 − $100,000.

If Buyer A's $60,000 arrives the following week instead, and everything else stays unchanged, the calculation falls to negative $10,000. That identifies a $10,000 shortfall before any desired cash cushion. It is a planning warning, not permission to overdraw an account.

The delayed $60,000 is part of Buyer A's existing receivables. Moving its expected collection date does not create another invoice or a new expense. Do not assume the remaining buyers will pay early to fill the gap.

Repeat the exercise for a longer delay and for a reduction in future orders. For the latter, estimate which costs can actually fall and when. Financing a timing gap and supporting permanently lower sales are different requests.

Ask how concentration affects the proposed funding

For receivables-backed financing, ask which customer balances qualify, whether concentration limits apply, and how the provider calculates them. The OCC handbook describes limiting concentrated accounts in a borrowing base or reducing the amount advanced against them. Actual treatment depends on the proposed facility and its agreement.

Do not translate a customer percentage into an assumed funding amount. Request a calculation using your own ledger, with exclusions and reserves identified. Our borrowing-base guide explains the distinction between accounting balances and available credit.

If considering factoring, ask how the factor evaluates the buyer and its invoices, what exposure it will accept, and who bears specified nonpayment risks. Those answers need to come from the proposed terms.

Keep the financing and collection scenarios consistent. If an invoice has already supported an advance, its later payment may go toward settling that financing. Avoid counting both the advance and the full collection as freely available cash.

Present the concentration and the plan together

A practical submission combines the customer summary, sales report, dated aging, supporting payment history, and cash scenarios. Explain what the requested capital would fund and how the business expects to repay it. Name the assumptions that would change the plan.
