Business Finance: Working Capital Without the Panic
Growth consumes cash before it produces it. We explain the mechanics of working capital, inventory and invoice finance so owners can fund the gap without giving away the company. Every story below is reported and edited by our team, with context, practical detail and primary sources you can follow.
How we report on business finance
Each business finance guide follows the same routine: a clear question, current primary sources and a worked example. We link the references we used and correct errors in public when we find them.
How to get the most from business finance
Start with the decision you are actually facing, whether that is how much cash to hold, which cover to renew or how to compare two loan offers. Our stories are written to be useful before and after the purchase, and the two below cover different sides of the same subject. Read both Working Capital and Invoice Financing and Factoring for the full picture.
When this subject matters most
Working capital pressure usually appears before a growth problem does: stock sits longer, customers pay later and the credit line gets tighter. Review receivables and inventory together, because improving one while ignoring the other often just moves the strain. Finance the timing gap, not a permanent shortfall, and keep a buffer for the months when everything is due at once. Background: the working capital cycle.
What our editors found in 2026
Working Capital: Every pallet in the warehouse is money that has already been spent and not yet earned back. For product businesses, inventory is usually the largest and most neglected source of working capital. Treated carefully, it can fund growth without a new loan; ignored, it quietly consumes the cash the business needs to operate.
Invoice Financing and Factoring: Waiting 60 days for a customer to pay is a financing decision made by default. Invoice finance turns those receivables into cash sooner, for a fee. It can be a lifeline for a growing business, but the cost and the contract terms vary enormously. This guide explains what you are actually buying.
Working capital is the part of finance that owners feel before they can name it. The order book looks healthy, the bank balance does not, and nobody is quite sure why. Usually the answer is a combination of inventory days, customer payment terms and supplier terms that have quietly shifted since the business was smaller.
There is no single right level of working capital. A subscription business can operate with very little; a distributor with long lead times needs more. What matters is that the level is chosen deliberately and funded with the right instrument. Using an overdraft to fund permanent stock is a common way to turn a temporary timing issue into a structural one.
Invoice finance and inventory finance can be useful, but they are not free and they are not neutral. They change your relationship with customers, your credit control process and sometimes your contractual obligations. We explain the mechanics and the exit terms, because the cheapest facility is not always the one with the lowest headline fee.
Common questions about business finance
What are inventory days? Average inventory divided by cost of goods sold, multiplied by 365. It shows how long cash is tied up in stock before it converts back through sales.
Is invoice factoring expensive? It can be, depending on fees and how long customers take to pay. Convert the total annual cost into a percentage of cash received and compare it with your gross margin.
How do I release cash from inventory? Review slow-moving stock quarterly, discount or return what will not sell, and adjust reorder rules so the same problem does not rebuild. Set a cash-release target and track it.
