In short
What you need to know.
Slow-paying business customers point to invoice finance; mostly card takings suit a merchant cash advance; a gap that keeps recurring suits a revolving facility; and a single, known shortfall suits a fixed working capital loan. Most options are unsecured, usually need a director's personal guarantee and cost more than borrowing secured on property.

Specialist knowledge. Better outcomes.
Cash flow finance is business funding that a lender provides based mainly on your trading performance and expected income, rather than on property or other assets. It exists because a profitable business can still run short of cash: customers pay late, stock has to be bought before it sells, tax bills land in quiet months and equipment breaks without warning. Cash flow finance fills those gaps so you can keep paying staff, suppliers and overheads. As a broker, Smart Funding Solutions helps you choose the structure that matches how your business actually earns, then approaches lenders suited to it.
Each option suits a different need. Start with the one closest to yours; we will compare the rest for you.

Most cash flow lending is unsecured. Instead of valuing assets, the lender looks at your recent business bank statements, turnover and existing commitments to judge whether you can comfortably afford the repayments. Depending on the product, you repay in fixed instalments, as a share of your takings, or only on the amount you have drawn.
Because there is no property security, lenders normally ask directors for a personal guarantee, and the cost is typically higher than for secured borrowing.
An example: wages, rent and utilities are due, a large customer pays late and an unexpected repair bill arrives in the same week. A short-term facility covers the gap so you meet your commitments, and you repay it as normal trading income comes in.
UK limited companies, partnerships and sole traders that are already trading, usually for at least six to twelve months, with steady deposits into a business bank account and room in their income to meet the repayments can typically qualify for cash flow finance. Lenders build that judgement from the following.
In practice, underwriters read several months of bank statements for the average monthly income, the lowest balances, any returned payments and repayments already going to other lenders. Two businesses with the same turnover can get very different answers: one lender may be comfortable with a hospitality business that dips every January, while another declines it on the same figures.
Credit history is only one factor. Many cash flow lenders put more weight on current trading, so options can still exist if your record is not perfect, usually at a higher cost or for a smaller amount.
Sole traders are assessed slightly differently, because there are no company accounts and you are personally liable for the debt. See sole trader business loans for the steps and documents involved.
Cash flow finance rarely needs property security, but most lenders ask for a director's personal guarantee and, on larger facilities, a debenture over the company.
The detail differs by product. With invoice finance the funder takes ownership of, or a charge over, the invoices themselves and usually a debenture, often backed by a warranty or indemnity from the directors. Revolving facilities and larger unsecured loans may be supported by a debenture and guarantee together, while some merchant cash advance providers rely mainly on the card takings. If you would rather not give a guarantee, see business loans without a personal guarantee; if you can offer property, a secured business loan may be cheaper over a longer term.
If you would rather not offer property, our guide to unsecured business loans explains how lenders decide without an asset and when a personal guarantee is needed.
If cash flow lending is too short-term or too costly for what you need, the main alternatives borrow against assets, spread a liability or use your existing bank facilities.
A cash flow loan for a small business is borrowing sized on your takings and bank statements rather than on property. It covers a gap between money going out and money coming in, and is repaid as the gap closes.
For smaller businesses, the options lenders on our panel offer most often are:
Sole traders and newer businesses have fewer lenders to choose from: see sole trader loans and start-up business loans.

| Advantages | Disadvantages |
|---|---|
| Usually no property security required | Typically more expensive than secured lending |
| Can be arranged quickly once the lender has what it needs | A personal guarantee is usually required |
| Short terms mean you are not paying long after the need has passed | Frequent repayments can themselves strain cash flow |
| Several structures, so repayments can match how you trade | Borrowing repeatedly to cover shortfalls can mask a deeper problem |
How the main business finance structures work. Lenders set their own terms, so treat this as a guide to the questions to ask.
| Option | How you repay | Security | Often used for |
|---|---|---|---|
| Unsecured business loan | Fixed instalments, usually monthly | No charge over assets; a personal guarantee is usually required | Growth, stock, tax bills and cash flow |
| Secured business loan | Fixed instalments, often over a longer term | A charge over property or other assets | Larger sums, property and refinancing |
| Revolving credit facility | Interest on what you draw; repay and redraw | Varies by lender and case | Recurring or uneven cash flow gaps |
| Merchant cash advance | A share of future card takings | No charge over assets | Card-taking businesses with uneven months |
| Asset finance | Regular payments over the life of the asset | The asset being financed | Equipment, vehicles and machinery |
| Invoice finance | Settled as customers pay their invoices | Your unpaid invoices | Businesses waiting on customer payment |
General information only. Every lender has its own criteria, and all finance is subject to status.
| Product | How you repay | Often suits |
|---|---|---|
| Working capital loans | Fixed instalments over a short term | A one-off gap or planned need, such as stock or a new contract |
| Revolving credit facility | Interest only on what you draw; repay and redraw | Recurring, unpredictable cash needs |
| Merchant cash advance | An agreed share of future card takings | Retail, hospitality and other card-heavy businesses |
| Revenue-based finance | A share of total or online revenue | Ecommerce and subscription businesses with recurring income |
| Emergency business loans | Usually fixed instalments | An urgent, unexpected shortfall that cannot wait |
| Invoice finance | Repaid as customers settle invoices | B2B businesses waiting 30 to 90 days for payment |
A simple way to choose: if the problem is customers paying slowly, look at invoice finance first; if income arrives mainly by card, a merchant cash advance may fit; if the need recurs, a revolving facility avoids borrowing repeatedly; and if it is a single, known gap, a fixed working capital loan keeps costs predictable. Our guide to selective invoice finance covers funding single invoices, and our guide to calculating working capital helps you size the gap before you borrow.
For a sector example, see florist business loans, where perishable stock and sharp seasonal peaks shape which of these products fits.
| Product | How it is priced | Security | Set-up time |
|---|---|---|---|
| Working capital loan | Interest rate, often plus an arrangement fee | Usually a personal guarantee | Often a few working days once complete |
| Revolving credit facility | Interest on what you draw, plus facility fees | Personal guarantee; debenture on larger limits | Typically two to four weeks |
| Merchant cash advance | A factor rate: a fixed total to repay | Future card takings | Often a few working days |
| Invoice finance | Discount charge on what you draw plus a service fee | Your unpaid invoices, usually with a debenture | One to three weeks for a new facility |
| Bank overdraft | Interest on the overdrawn balance, plus bank fees | Varies by bank | Through your own bank |
An overdraft can be reduced or withdrawn by the bank, which is why many businesses use one of the other products alongside it. See the British Business Bank: business overdrafts guide and our comparison of overdrafts and business loans.
A business needs £50,000 to cover wages and suppliers while a large customer pays. The rates below are illustrative assumptions within the ranges on our panel (October 2026), not quotes.
| Option | Assumption | Approximate cost |
|---|---|---|
| Short-term loan | 15% a year, repaid over 6 months | About £2,210 in interest |
| Revolving credit | 30% a year, £50,000 drawn for 3 months then repaid | About £3,750 in interest |
| Merchant cash advance | Factor rate 1.25 | £12,500, however quickly it is repaid |
| Invoice finance | 8% a year on £50,000 for 2 months, plus a 0.5% service fee on £100,000 a month of invoices | About £1,667 |
The cheapest option depends on how long you need the money and what you can offer: invoice finance only works if you invoice other businesses, and a merchant cash advance only if you take card payments. Arrangement fees are extra. Try your own figures in the business loan calculator or the merchant cash advance calculator.

Indicative ranges from lenders on our panel, checked October 2026; your rate depends on your circumstances. Figures come from the rate cards these lenders give us as a broker, with amounts shown within the £10,000 to £20 million range we arrange. Lenders set their own criteria and pricing, approval is always the lender's decision, and this is not a quote.
Unsecured loans and merchant cash advances are often decided within a few working days of a complete application, while revolving facilities and whole-turnover invoice finance typically take two to four weeks, because the lender reviews accounts, credit control and the sales ledger before the facility goes live.
Cash flow finance is one part of our wider range of business finance. UK limited companies, partnerships and sole traders can enquire.
Some options are available. Invoice finance can suit newer businesses that sell to creditworthy customers, because the lender relies mainly on those customers paying. Merchant cash advances usually need a history of card takings, and most unsecured loans require some trading record. The government-backed Start Up Loans programme is another route for very new businesses; see our start-up business loans page.
Yes, sole traders can use most cash flow finance, including working capital loans, merchant cash advances and invoice finance where they sell to other businesses. Lenders will look at business bank statements, personal credit and tax returns. Finance of £25,000 or less to sole traders and small partnerships can be regulated consumer credit, which some lenders do not offer. Our page on sole trader loans covers the options.
The cost of cash flow finance depends on the product, the amount, the term, your trading history and your credit profile. Because most of it is unsecured, it usually costs more than borrowing secured on property. Merchant cash advances and very short-term loans tend to carry a higher total cost, while revolving facilities only charge interest on what you draw. Compare offers on the total amount repayable, not just the monthly figure.
Neither is always better; it depends on the shortfall. An overdraft is flexible but can be reduced or withdrawn by the bank, while cash flow finance such as a revolving credit facility or working capital loan is usually agreed for a set period. Businesses that have outgrown their overdraft limit often add another facility alongside it. Our guide to an overdraft versus a business loan compares the two.
Yes, cash flow finance can be used to pay a VAT bill, but a dedicated VAT loan is often a closer fit. A VAT loan spreads a single quarter's bill over the months until the next return, so repayments line up with when the tax would otherwise be saved. Lenders will check that the business can meet both the loan and future VAT. See our page on VAT loans for how these work.
Cash flow finance is borrowing that bridges the gap between paying costs and receiving income, such as working capital loans, revolving credit, invoice finance, merchant cash advances and VAT loans. It is usually sized on the business's turnover and cash flow rather than on property or other security. Our guide to internal and external sources of finance sets it alongside other ways to fund a business.
It depends on how long you need the money and what the lender can rely on. Invoice finance and revolving credit charge only on what you use, so they can cost less for short gaps; a merchant cash advance has a fixed total cost however fast you repay. Compare the total cost for your own timescale.
Unsecured loans and merchant cash advances are often decided within a few working days of a complete application, while revolving facilities and whole-turnover invoice finance typically take two to four weeks. See emergency business loans if the need is urgent.
