Using a Business Line of Credit to Fund Inventory
Inventory purchases often require payment upfront or on short terms while revenue from selling that inventory arrives weeks or months later. A line of credit can fund the purchase, then be repaid as inventory converts to sales.
The inventory funding cycle
The cycle works in three stages: purchase inventory on credit, sell the inventory to generate revenue, repay the line. The faster inventory turns, the more cost-efficient the financing — a product that sells in 30 days carries far less interest cost than one sitting in a warehouse for 6 months.
A wholesale distributor purchases $80,000 of product on net-30 supplier terms. It draws from its line to fund the purchase, sells the inventory over the next 45 days, collects payment, and repays the draw. At 15% annual rate, a $80,000 draw for 45 days carries roughly $1,479 in interest — an illustrative estimate only.
Inventory turns and cost efficiency
Before using a line for inventory, model the carrying cost against the expected margin. If inventory turns in 30 days and the line costs 1% per month, the cost of funding each cycle is manageable. If inventory turns in 120 days and the margin is thin, the interest cost may significantly erode profit.
Seasonal inventory pre-buys
Seasonal businesses often need to build inventory 60–90 days before peak revenue. A line can fund the build, then be repaid when the season's sales arrive. This is a common and appropriate use case, but it requires enough credit limit to absorb the full pre-buy.
- Retail: Q4 holiday inventory built in September–October
- Landscaping/outdoor: Spring equipment and supply stock
- Agriculture: Seed and fertilizer before planting season
- Tourism: Staffing and supply build-up before peak travel season
Supplier negotiation leverage
Access to a credit line can also enable early payment discounts from suppliers. A supplier offering 2% off net-30 invoices for payment within 10 days effectively offers a 36% annualized return on that early payment. Funding that early payment from a 15% line still yields a net gain.
Frequently Asked Questions
- Can I use a line of credit for any type of inventory?
- Most commercial lines are general-purpose and can be used for inventory. Some asset-based lines specifically use eligible inventory as collateral and may restrict what qualifies. Review the facility agreement for any use restrictions.
- What if the inventory doesn't sell as fast as expected?
- Slower-than-expected inventory turns mean the draw stays outstanding longer and interest costs rise. Plan for realistic sell-through timelines, not optimistic ones, when sizing a draw.
- Is a line of credit better than a purchase order loan for inventory?
- PO financing is typically more expensive but can cover larger, specific purchase orders without requiring an established credit facility. A line of credit offers more flexibility for ongoing inventory needs once approved.
