A wholesale buyer keeps increasing their orders. Production has a steadier rhythm, sales are rising, and buying more equipment starts to feel reasonable. Then the buyer postpones a reorder. Their printed cartons are already on your shelf, and the extra payroll commitment has not moved.
This is customer concentration risk: too much of the business depends on one customer or a small group of customers. The relationship can be valuable and the dependence still worth managing. Healthy growth means knowing what happens if that buyer orders less, pays later, or leaves—not assuming they will.
How much of the business depends on this buyer?
Start with a consistent sales period, such as the last completed twelve months. Use net sales after returns and discounts, and apply the same accounting basis to the customer and company totals.
Customer revenue share = customer net sales ÷ total net sales × 100
Suppose a fictional craft-kit business recorded $240,000 in annual sales. One retailer generated $96,000. That buyer represents 40% of sales. Also check the most recent quarter: an annual average can hide how dependent the business has become lately.
The percentage is a starting point, not a verdict. There is no single safe revenue share for every maker. Payment reliability, committed purchases, alternative customers, and the ability to redirect stock all matter. The OCC’s asset-based lending guidance describes the risk when a major customer takes its business elsewhere or weakens financially. Its lending thresholds are not universal operating limits for product businesses.
Which commitments would remain if orders stopped?
Sales concentration alone misses the physical exposure. List what you have committed specifically for the buyer:
- Unpaid invoices: amounts already owed, due dates, disputes, and actual payment history.
- Dedicated inventory: branded cartons, special components, work in progress, and finished goods other customers cannot readily buy.
- Future purchases: supplier commitments, cancellation terms, and deposits already paid.
- Ongoing capacity: staffing, space, or equipment commitments added to serve the account.
Record which items can be reused, canceled, or redirected, and the time and cost involved. Do not call custom packaging recoverable merely because it is physically undamaged. A box printed for a retailer may have little use elsewhere.
Review product margins too. A buyer’s share of contribution can differ from their share of revenue. For costs that remain after sales disappear, use the guide to which costs actually disappear when a product is dropped; the same distinction helps avoid assuming every expense falls with orders.
What happens if the next reorder does not arrive?
Run two separate scenarios before combining them. A missing future order and a late payment on goods already shipped create different problems.
Scenario one: no reorder next month
In the fictional business, a normal monthly order from the retailer is $8,000. Fulfilling it would require $4,800 of avoidable variable costs. If the order never arrives and those costs can genuinely be avoided, the business loses $3,200 of contribution—not $8,000 of profit.
Rent and committed salaries still need funding. Materials already purchased do not turn back into cash. Identify what purchasing can stop now and what is already locked in. Then check whether other customers can use the freed operational capacity without new spending or unrealistic sales assumptions.
Scenario two: the shipped order pays a month late
An $8,000 invoice expected this month instead clears next month. Compared with the original cash plan, this month’s receipts are $8,000 lower. The delay is not automatically an $8,000 accounting loss, but payroll and supplier payments still arrive.
Move the expected receipt in a weekly cash forecast and look for the lowest projected cash balance. The SBA’s financial-management guidance distinguishes accounting timing and emphasizes tracking money in and out. Keep receivables, cash, and future sales assumptions separate.
Only then test both events together. Do not add the contribution loss and delayed receipt and call the total “lost profit.” For the broader distinction, see the revenue-growth, contribution, and cash review.
Build a buyer-dependence review card
Use one page for your largest account. These five fields make the review actionable:
| Field | What to record |
|---|---|
| Dependence | Revenue share for the year and recent quarter; contribution where reliable. |
| Cash exposure | Unpaid invoices, expected collection dates, and the late-payment scenario. |
| Stock exposure | Buyer-specific inventory and noncancelable purchases, with realistic reuse options. |
| Operating response | What can stop or be reassigned, who decides, and by when. |
| Next commitment | The next purchase or capacity decision, its approval condition, and the review owner. |
Choose a trigger tied to an actual decision: review before ordering another run of branded packaging, extending payment terms, or adding a recurring staffing commitment. A percentage alone does not tell someone what to do Monday morning.
How can you reduce exposure without losing a good customer?
Start with the commitment creating the most strain. Discuss deposits for custom materials, smaller releases, clearer reorder windows, or staged deliveries where commercially workable. Agree changes in writing rather than assuming an informal forecast is a purchase commitment.
Build sales elsewhere deliberately, but do not replace one oversized account with a collection of unprofitable orders. Protect service for existing smaller customers and reserve realistic capacity for new ones. The wholesale reorder review can help turn the last delivery’s lessons into better terms for the next.
Frequently asked questions
Should stores owned by one group count separately?
Keep store-level records, but also aggregate the parent group when purchasing decisions or payment risk are shared. Several delivery addresses do not necessarily mean independent customers.
Is marketplace dependence the same thing?
Not exactly. Many customers can buy through one platform. Track that channel dependence separately: an account restriction or policy change could interrupt access to otherwise independent buyers.
Does a signed purchase order remove the risk?
No. Review payment, cancellation, acceptance, and dispute terms. A purchase order is not cleared cash or a guarantee of future reorders. Get qualified advice when contractual exposure is significant.
What if the business is too young for a full year of sales?
Use the available completed months and label the period clearly. Keep actual sales separate from forecasts, and avoid treating one opening order as evidence of a stable annual pattern.
Make the next growth decision with the downside visible
Before approving more customer-specific purchases, complete the review card for your largest buyer. Name one safeguard, one owner, and the next review date. Revenue growth is easier to trust when the business can explain how it would handle an interruption.
