Inventory Finance vs Invoice Finance

Cash flow problems do not always mean your business is failing. Often, cash is stuck in one of two places, stock on your shelves, or invoices sitting unpaid.

That’s where inventory finance and invoice finance can help. They both support working capital, but they solve different problems.

Inventory finance vs invoice finance, quick definitions

What is inventory finance?

Inventory finance provides funding to buy or hold stock. The lender uses your unsold inventory as security. It is common in retail, wholesale, and manufacturing. If you want to go deeper, see our overview of stock and inventory finance.

What is invoice finance?

Invoice finance advances cash against invoices you have already issued. The lender uses your accounts receivable as security. For a full explainer, read what is invoice finance. You can also compare the basics with the British Business Bank guide on invoice finance.

The core difference in one line

Inventory finance helps you pay for stock before a sale. Invoice finance helps you get paid faster after a sale.

When to choose inventory finance

Choose inventory finance when you need stock to create sales, but cash is tight. It is a good fit when demand is predictable but timing is the problem.

• You need to buy raw materials or finished goods to fulfil demand.
• You have seasonal peaks and need stock ahead of time.
• You can track inventory well and turn it over at a steady pace.
• You want funding that matches stock cycles, not invoice cycles.

If you sell online, this can be a strong match. See our page on stock and inventory finance for ecommerce. If you run a shop or retail chain, see stock and inventory finance for retail.

A key metric here is how fast your stock sells. Learn more about inventory turnover.

When to choose invoice finance

Choose invoice finance when you have completed work or delivered goods, but you are waiting 30 to 90 days to get paid. It can turn “sales on paper” into cash you can use today.

• You sell to other businesses on payment terms.
• You are growing and payroll or suppliers are due before customers pay.
• You want funding that scales as your invoice book grows.
• You want to smooth out cash flow without waiting on slow payers.

If you want benchmarks, see our roundup of invoice finance statistics in the UK. Late payment is also a common cause of cash pressure, and the Office of the Small Business Commissioner has guidance on legal action for late payments.

Collateral, customer contact, and day to day impact

Collateral

Inventory finance is secured on stock. Invoice finance is secured on unpaid invoices. In plain terms, one is tied to products, the other is tied to customers who owe you money.

Customer contact

Inventory finance usually stays behind the scenes. Invoice finance depends on the setup.

• With invoice factoring, the provider may collect payment from customers.
• With invoice discounting, you usually keep control of collections.

Industry bodies often group these products under invoice finance and asset-based lending. See UK Finance’s overview of invoice finance and asset-based lending.

Costs, risks, and what to watch out for

Inventory finance

Costs depend on stock quality, storage, and how easy it is to resell. Risk rises if inventory is slow-moving, perishable, or hard to value.

Invoice finance

Costs depend on invoice volume, debtor quality, and the service level you choose. Some structures can reduce risk if the provider takes on certain bad-debt risk, but it varies by contract.

When you compare offers, do not only look at the headline rate. Make sure you understand the total cost. This guide can help: factor rate vs APR. It is also worth reviewing hidden costs in UK business loans.

One more safety tip: only deal with trusted providers and watch for scams. The FCA explains how to protect yourself from scams.
