Quick answer
Popular business finance guides
Working capital finance covers day-to-day running costs — stock, payroll, suppliers — when cash flow is tight or seasonal. Options include unsecured loans, revolving credit facilities, invoice finance, merchant cash advances and overdraft alternatives, typically £5,000–£500,000. It is short-term by design (often 3–24 months), funds fast (24–72 hours), and is priced on turnover and trading history rather than long-term assets.

What is working capital?
Working capital is the money available to cover your short-term, day-to-day costs. In accounting terms, it is current assets minus current liabilities. In plain terms, it is the cash you can use right now to run the business.
Current assets include cash, stock and money owed by customers. Current liabilities include supplier bills, wages, tax and short-term debt. When assets comfortably exceed liabilities, you have positive working capital.
Healthy working capital means you can pay bills on time without stress. Weak working capital means you risk running short, even if the business is profitable on paper.
What is the working capital gap?
The working capital gap is the delay between paying for something and getting paid for it. It is the heart of most cash flow problems. The longer the gap, the more cash you need to bridge it.
A typical cycle looks like this:
- You buy stock or materials and pay the supplier.
- You produce or sell the goods or service.
- You invoice the customer on, say, 30 or 60-day terms.
- You wait until the customer finally pays.
During that wait, your money is locked up. If you must buy more stock or run payroll before the customer pays, you face a gap. Working capital finance fills it.
Why the gap matters for growth
Counter-intuitively, fast growth widens the gap. The more you sell, the more stock and labour you fund upfront, and the more cash sits in unpaid invoices. Profitable businesses can still run out of cash. That is why funding the gap is a growth issue, not just a survival one.
The main working capital finance options
There is no single working capital product. Instead, there is a toolkit, and the right tool depends on the shape of your gap. Below are the five most common options and when each fits.
Term loan
A term loan gives you a lump sum repaid over a fixed period with set instalments. It suits a known, one-off need, such as a large stock order or a confident push into a busy season. Repayments are predictable, which helps budgeting. Learn the basics in our guide to how business loans work.
Business overdraft
An overdraft lets you dip below zero on your current account up to an agreed limit. It is flexible and you only pay for what you use. However, banks have reduced or withdrawn many overdrafts, so alternatives are now important. We cover these in detail in our guide to business overdraft alternatives.
Revolving credit facility
A revolving credit facility works like a flexible pot of money you can draw from, repay and draw again. You pay interest only on the balance you use. It is well suited to recurring or unpredictable gaps, giving overdraft-style flexibility from a non-bank lender.
Invoice finance
Invoice finance advances cash against your unpaid invoices, so you do not wait 30 or 60 days to get paid. It scales with your sales, which makes it ideal when the gap is caused by slow-paying customers. See our guide to what invoice finance is for how it works.
Merchant cash advance
A merchant cash advance gives you a lump sum repaid as a percentage of your daily card takings. It suits retail and hospitality businesses with strong card sales but uneven cash flow. Repayments flex with your revenue. Explore it on our merchant cash advance page.
How to choose the right option
The best facility matches the cause and shape of your gap. Start by asking what is actually creating the shortfall, then pick the tool that fits.
- One-off, known cost? A term loan gives certainty.
- Small, unpredictable swings? An overdraft or revolving credit suits.
- Slow-paying customers? Invoice finance unlocks the cash you are owed.
- Strong card sales? A merchant cash advance flexes with revenue.
- Seasonal peaks? A flexible facility you can draw and repay works best.
Many businesses combine options. For example, a term loan for a big stock order plus invoice finance to keep cash moving day to day. A broker can map the right mix across a panel of lenders.
How to size a working capital facility
Sizing a facility means matching the amount to your real gap, not guessing. Too little leaves you short, while too much costs more than you need. The aim is to cover your peak, not your average.
A simple approach is to work through your cycle:
- Map your outgoings across a typical month, including wages and suppliers.
- Map your income, allowing for real payment dates, not invoice dates.
- Find the biggest shortfall in any single period during the year.
- Add a buffer for late payers or an unexpected cost.
That peak shortfall is roughly the facility size you need. You can test repayment scenarios for any term loan element using our business loan calculator.
What does working capital finance cost?
Cost depends on the product, the amount and your business profile. Each option prices differently, so compare like for like on the total cost of borrowing.
- Term loans charge interest over the term, usually as an APR.
- Overdrafts and revolving credit charge interest on the drawn balance, plus possible facility fees.
- Invoice finance charges a service fee plus a discount fee on advances.
- Merchant cash advances use a factor rate, a fixed cost agreed upfront.
Flexible facilities can look cheaper because you pay only for what you use. Lump-sum loans give certainty but charge across the full balance. The cheapest option on paper is not always the best fit for your cash flow pattern.
When comparing quotes, look beyond the headline rate. Check for arrangement fees, minimum charges, early-repayment terms and any renewal costs. A facility with a slightly higher rate but no minimum fee can work out cheaper if your usage is light. The right comparison is always the total cost over the period you actually expect to use the money.
Managing seasonal cash flow
Seasonal businesses feel the working capital gap most sharply. Income arrives in bursts, but costs run all year. The goal is to fund the quiet months without overpaying in the busy ones.
Build before the peak
Retailers and hospitality firms often stock up and hire before their busiest season. That spending lands before the sales arrive. A flexible facility lets you fund the build-up, then repay as revenue flows in.
Smooth the quiet months
In the off-season, fixed costs continue while income falls. A revolving facility you can draw from and repay as needed avoids paying interest all year for cash you only need for part of it. Matching the facility to the season keeps costs down.
Working capital finance vs longer-term borrowing
Working capital finance is for short-term, recurring needs. It is not designed to fund big, long-life investments. Using the wrong type of finance for the wrong purpose is a common and costly mistake.
Keep these distinctions in mind:
- Short-term gaps suit flexible, short-term funding you can repay quickly.
- Long-term assets such as premises or machinery suit longer-term loans or asset finance.
- Matching the term to the life of the need keeps total cost sensible.
For equipment and machinery specifically, see our guide to asset finance, which spreads the cost over the asset’s working life rather than your cash flow cycle.
Signs your business needs working capital finance
Many businesses leave it too late to arrange funding, then scramble when a gap bites. Spotting the warning signs early gives you time to choose the cheapest option calmly.
Common signs include:
- Paying suppliers late while waiting for customers to pay you.
- Dipping into an overdraft every month rather than occasionally.
- Turning down orders because you cannot fund the stock or labour.
- Tax deadlines causing stress, such as a VAT or PAYE bill.
- Profit on paper but no cash in the bank to match it.
None of these means the business is failing. They usually mean growth or seasonality has outpaced your cash. That is exactly what working capital finance is designed to fix. If a tax bill is the trigger, our guide to VAT loans covers a focused option.
The working capital ratio explained
Lenders and accountants often measure working capital using a ratio. It gives a quick read on whether you can cover short-term bills.
The working capital ratio, also called the current ratio, divides current assets by current liabilities. The result tells you how many times over you could cover your short-term debts.
- Below 1: liabilities exceed assets, which signals cash flow risk.
- Around 1.5 to 2: generally considered healthy for most businesses.
- Well above 2: safe, but may mean cash is sitting idle rather than working.
The ideal ratio varies by sector. A retailer with fast stock turnover can run leaner than a manufacturer with long production cycles. Use the ratio as a guide, not a hard rule.
How to improve working capital without borrowing
Funding is not the only lever. Tightening how cash moves through your business can shrink the gap before you borrow a penny.
Practical steps include:
- Invoice faster and chase payment promptly to shorten the wait.
- Negotiate terms with suppliers to align outgoings with income.
- Manage stock so cash is not tied up in slow-moving inventory.
- Offer card payment to speed up collection at the point of sale.
- Review pricing to protect the margin that funds your cash buffer.
These habits reduce how much finance you need and make any facility cheaper. Borrowing works best alongside good cash discipline, not instead of it.
Working capital finance by sector
The shape of the working capital gap varies a lot by industry. The best funding option often follows from how a sector earns and spends.
Retail and e-commerce
Retailers buy stock upfront and sell it over weeks or months, so cash is tied up in inventory. Demand also peaks at certain times of year. A flexible facility or a merchant cash advance, repaid from card sales, tends to fit because it flexes with takings.
Manufacturing and wholesale
Manufacturers fund raw materials and labour long before goods ship and invoices are paid. The gap can run for months. A combination of a term loan for materials and invoice finance to bridge slow-paying trade customers usually works well.
Professional services
Service firms carry less stock, but they pay staff monthly while clients pay on 30 or 60-day terms. Their gap is almost entirely about timing. Invoice finance, which releases cash as invoices are raised, is often the cleanest fit.
Construction and contractors
Construction firms face staged payments, retentions and long projects, which stretch cash badly. Tailored facilities and project funding help, alongside disciplined invoicing. The key is matching the funding term to the project length.
Working capital finance vs a merchant cash advance or VAT loan
Working capital finance is an umbrella term, and some specific products sit under it. Two common questions are how it relates to a merchant cash advance and a VAT loan.
The distinctions are simple:
- Merchant cash advance: a specific working capital product repaid from card sales, suited to retail and hospitality. Compare it with a loan in our guide to a merchant cash advance vs a business loan.
- VAT loan: a focused facility that funds a single tax bill rather than general operations.
- General working capital finance: covers the broad day-to-day gap, using whichever product fits best.
In practice, many businesses layer these. A general facility handles the everyday gap, while a VAT loan smooths the quarterly tax spike. The aim is always to match each tool to a specific need rather than over-borrowing on one product.
How to apply for working capital finance
Applying is faster when you prepare your numbers. Lenders want to understand your cash flow and your ability to repay.
Have these ready:
- Recent bank statements, usually 3 to 6 months.
- Up-to-date accounts or management figures.
- An aged debtor report if you want invoice finance.
- Card sales data if you are considering a merchant cash advance.

Frequently Asked Questions
Working capital finance is short-term funding that covers the gap between money going out and money coming in. It helps pay wages, stock and suppliers when cash is tied up in unpaid invoices or seasonal swings, using options such as loans, overdrafts, revolving credit and invoice finance.
The working capital gap is the delay between paying for stock, wages and suppliers and getting paid by your customers. The longer your payment terms, the wider the gap and the more cash you need to bridge it.
It depends on what causes your gap. A term loan suits a known one-off cost, invoice finance suits slow-paying customers, revolving credit suits unpredictable swings, and a merchant cash advance suits strong card sales. Many businesses combine more than one.
Map your outgoings and real income dates across the year, then find your single biggest shortfall and add a buffer for late payers. Size the facility around that peak gap rather than your average month, so you are never caught short.
No. Growing and seasonal businesses use it most, because fast growth ties up cash in stock and unpaid invoices. Profitable firms often need working capital finance to fund expansion, not to survive.
Many facilities can be arranged within a few days, and some flexible products fund within 24 to 48 hours. Speed depends on the product and how quickly you provide bank statements, accounts and any debtor or card sales data.
Short-term working capital options compared
When the gap is days or weeks — payroll due before an invoice clears, a VAT bill landing mid-month — the right product is the one that funds fastest at an acceptable cost for a short period:
| Option | Speed to cash | Typical cost | Best for |
|---|---|---|---|
| Invoice finance (spot/selective) | 24–48 hrs per invoice | 1–4% of invoice value | A specific unpaid invoice |
| Revolving credit facility | 24–48 hrs once set up | Interest only on drawn funds | Recurring short gaps |
| Merchant cash advance | 24–72 hrs | Factor rate 1.1–1.5 | Card-heavy businesses |
| Short-term unsecured loan | 24–48 hrs | ~8–25% APR | One-off known amounts |
| Bank overdraft | Days–weeks to arrange | EAR ~10–15% + fees | Small, occasional buffers |
