Cash Flow Management for US Medical Device Distributors: Inventory, Credit Terms, and the Working Capital Trap
US medical device distribution is a working capital intensive business — distributors buy from manufacturers on 30-day terms but wait 60 to 90 days for hospital and health system payments. Managing this gap without choking growth is the core financial challenge of the business.

The Working Capital Challenge of Medical Device Distribution#
US medical device distributors sit in one of the most demanding working capital positions in American commerce. They purchase product from device manufacturers on net 30 payment terms, then sell to hospitals, surgery centers, and physician offices that operate on net 60 to net 90 terms — often longer in practice. The resulting cash flow gap can consume 20 to 30 cents of every revenue dollar in working capital requirements as a distributor grows. A distributor growing from $5 million to $10 million in annual revenue may need $500,000 to $1 million of additional working capital simply to fund the growth — capital that must come from operations, credit lines, or equity.
Accounts Receivable Management: The First Line of Cash Defense#
Days sales outstanding (DSO) — the average number of days it takes to collect payment after invoicing — is the most important cash flow metric for US medical device distributors. Industry data suggests DSO ranges from 45 to 75 days for distributors serving hospitals and integrated delivery networks. Each day of DSO reduction at a $10 million revenue distributor represents approximately $27,000 of released working capital. Achieving DSO reductions requires systematic invoice follow-up processes, early payment discount programs for large health system customers, and willingness to place accounts on hold when they age beyond agreed terms — a step many distributors avoid for fear of damaging customer relationships.
Inventory Management: Balancing Service Level and Cash#
Medical device distributors must maintain sufficient inventory to fulfill surgeon and hospital requirements — often with same-day or next-day delivery expectations for implants and capital equipment consumables. This service requirement conflicts directly with cash flow, as excess inventory ties up working capital. Calculating inventory turns by product category — cost of goods sold divided by average inventory value — reveals which product lines are generating healthy turns and which are accumulating slow-moving stock. Distributors targeting 6 to 8 inventory turns annually in core product lines have materially better cash efficiency than those at 3 to 4 turns.

Consignment Inventory: The Double-Edged Model#
Many US medical device distributors maintain consignment inventory at hospital accounts — product left on-site at the customer that is only invoiced when used. Consignment improves fill rates and embeds the distributor in the clinical workflow, but it dramatically increases total inventory investment. A distributor managing $2 million in consignment inventory across 20 hospital accounts has effectively extended $2 million in interest-free credit to those accounts. Analyzing which consignment accounts generate sufficient volume and margin to justify the working capital cost — and pulling consignment from underperforming accounts — can release significant cash without meaningful revenue impact.
Supplier Terms and Early Payment Discounts#
The supplier payment side of the working capital equation is often overlooked by US medical device distributors focused on receivables. Negotiating extended payment terms from manufacturers — net 45 or net 60 rather than net 30 — and capturing early payment discounts when cash is available are two complementary strategies that improve working capital efficiency. A 2/10 net 30 discount (2% discount for payment within 10 days) represents a 36% annualized return on the early payment, making it one of the most economically attractive uses of short-term cash a distributor can make.
Credit Line Structuring for Distribution Businesses#
US medical device distributors should structure their bank credit facilities as revolving lines of credit tied to eligible accounts receivable and inventory — asset-based lending facilities that scale with the business as it grows. Traditional term loans provide fixed capital that does not flex with seasonal or growth-driven working capital needs. An asset-based line of credit that allows borrowing up to 85% of eligible receivables and 50% of eligible inventory automatically expands as the business grows, reducing the risk of working capital constraints limiting growth during periods of rapid revenue expansion.
Building a Cash Flow Forecast for Distribution Businesses#
US medical device distributors should maintain a 13-week rolling cash flow forecast that maps expected collections from aged receivables against committed supplier payments, payroll, and operating expenses. This forecast should be updated weekly from actual AR aging reports and projected order flow. Distributors who operate without a cash flow forecast consistently face surprise cash gaps when a large receivable is delayed or an unexpected inventory purchase is required. Those who forecast consistently have time to arrange credit line draws, negotiate short-term deferrals, or accelerate collections before a gap becomes a crisis.
People also ask
What is DSO and why does it matter for medical device distributors?
Days sales outstanding (DSO) measures the average number of days between invoicing and cash collection. For US medical device distributors, DSO is the primary cash flow metric because health system customers pay slowly. Each day of DSO reduction releases working capital equal to daily revenue divided by 365.
How do US medical device distributors manage consignment inventory?
Effective consignment management involves calculating the working capital cost of each consignment account, comparing it to the gross margin generated, and pulling inventory from accounts where the return does not justify the capital commitment. Distributors should review consignment account profitability at least quarterly.
What type of bank financing is best for a US medical device distributor?
Asset-based revolving credit facilities tied to eligible accounts receivable and inventory are generally the most appropriate financing structure for US medical device distributors. These lines of credit scale automatically with the business, providing working capital that grows as revenue grows rather than requiring periodic renegotiation.
How many inventory turns should a medical device distributor target?
Most US medical device distributors target 6 to 8 inventory turns annually for core product lines, though consignment requirements and service level obligations can reduce effective turns in practice. Turns below 4 typically indicate excess stock, slow-moving inventory, or consignment commitments that should be re-evaluated.
