Walk into any product business that's growing and you'll find the same quiet problem: the cash is in the warehouse. You spent it on stock that hasn't sold yet, and until it does, you can't use that money for rent, payroll, or the next purchase order. On paper you're profitable. In the bank account, you're stretched thin.
This is the cash-conversion problem, and it's the single biggest reason healthy product businesses run out of money. The fix isn't to stock less — it's to fund inventory the right way so your own cash isn't trapped on a shelf. This guide walks through the options, when each fits, and how much to take.
The real problem: cash trapped in stock
Every product business runs a cycle. You buy inventory, hold it, sell it, and collect cash — then do it again. The time between paying your supplier and collecting from your customer is the cash-conversion cycle, and the longer it runs, the more of your own money is locked up at any given moment.
Here's why that bites. Say you buy $40,000 of stock that takes 60 days to sell through. For those 60 days, $40,000 is unavailable for anything else. Now multiply that across a full catalog and a growth curve where you're constantly reordering before the last batch clears. Growth actually worsens the squeeze, because each bigger order pulls more cash out before the previous one comes back.
Inventory financing breaks the dependency between buying stock and having the cash on hand to buy it. You fund the purchase, sell the goods, and repay from the proceeds — keeping your operating cash free for everything else the business needs. If this dynamic is new to you, our primer on what working capital actually is lays the foundation.
Your four options for funding inventory
There's no single "inventory loan." There are four common structures, and the right one depends on whether your need is recurring, one-time, or tied to a specific large order.
A line of credit — the workhorse for recurring stock
A revolving line of credit is the most natural fit for most product businesses. You get a credit limit, draw against it to buy inventory, and repay as the stock sells — then draw again for the next order. You pay interest only on the balance you're actually using, which makes it efficient for the constant buy-sell rhythm of retail and ecommerce.
The big advantage is that a line is pre-arranged. You set it up once, then it sits ready. When a supplier offers a volume discount or a hot SKU needs restocking, you draw same-day instead of scrambling.
Inventory financing — stock as collateral
True inventory financing is a loan secured specifically by the goods you buy. Because the inventory backs the loan, lenders can extend more than they would on an unsecured basis — typically advancing 50–80% of inventory value, depending on how easily the stock resells. Fast-moving, non-perishable goods support the highest advances.
Purchase-order financing — funding an order you can't fulfill
Landed a big order but can't afford to produce or buy the goods to fill it? Purchase-order financing pays your supplier directly so you can complete the order. Once you deliver and your customer pays, the financing is settled. It's built for the specific situation where a single large order is bigger than your cash can handle.
Revenue-based financing — fast, flexible cash
When you need stock money fast and your sales swing month to month, revenue-based financing advances a lump sum that you repay as a percentage of sales. Slow week, smaller payment; big week, bigger payment. It often funds same-day, which is why owners reach for it when a stocking opportunity won't wait.
Comparing the options side by side
| Option | Best for | How you repay | Typical speed |
|---|---|---|---|
| Line of credit | Recurring restocking, smoothing the buy-sell cycle | Repay as stock sells; reuse the limit | 24–48 hours |
| Inventory financing | Larger stock buys backed by resellable goods | Fixed payments; stock secures the loan | 1–3 business days |
| Purchase-order financing | A single big order beyond your cash | Settled when your customer pays | A few days |
| Revenue-based financing | Fast cash, uneven or seasonal sales | A percentage of daily/weekly sales | Same day |
The honest summary: a line of credit covers the everyday rhythm, purchase-order financing handles the one-off giant order, and revenue-based financing wins on speed and flexibility. Many product businesses use a line as their backbone and reach for the others situationally. If you're weighing a revolving line against a lump sum, Business Line of Credit vs. Term Loan settles that decision directly.

If your year has a peak — Q4 retail, a summer rush, a holiday catalog — inventory financing is what lets you stock deep enough to actually capture it. The mistake is funding a seasonal buy with permanent debt. You don't need year-round capital for a three-month surge; you need funding that ramps up and pays down with the season.
A practical seasonal playbook:
- Draw ahead of the peak. Use a line of credit to buy stock 6–10 weeks before demand hits, while suppliers can still deliver.
- Repay through the season. As sales convert the stock to cash, pay the line back down so you're not carrying interest in the slow months.
- Match the product to the swing. If your sales are sharply seasonal, revenue-based financing's flexible repayment can be gentler than a fixed monthly term payment that's due whether it's your busy month or not.
How much should you take?
Size the funding to the inventory plan, not to the maximum you can be approved for. Every dollar you borrow carries a cost, and over-borrowing on stock that sells slowly is how a profitable business ends up cash-strapped anyway.
A few benchmarks to anchor on:
- Against inventory as collateral: expect an advance of 50–80% of stock value — higher for fast-moving, easily resold goods.
- For unsecured working capital used on stock: a common range is 10–30% of annual revenue.
- For a seasonal buy: base the amount on your sell-through forecast for the season, with a modest buffer — not on last year's hopes.
Whatever you borrow, the test is the same: can the stock you're buying generate enough margin, fast enough, to cover the repayment comfortably? If yes, financing inventory is one of the highest-return uses of capital a product business has.

The bottom line
Inventory is supposed to make you money, not hold your money hostage. The right financing breaks the link between buying stock and draining your account: a line of credit for the everyday cycle, purchase-order financing for the order that's too big to self-fund, and revenue-based financing when you need speed and flexibility. Match the structure to the need, size it to your real forecast, and your cash stays free to run the business — while your shelves stay full.
