Working capital lenders: cash flow loans and facilities compared

Working capital lenders fund the gap between paying out and getting paid. They do it in four different ways, and the right one depends on why your cash runs short. This page groups UK lenders by facility type, using each lender’s own published terms, and shows which type suits a seasonal business and which a growing one.

The short answer

Working capital lenders offer four main kinds of cash flow finance: short-term loans, revolving lines of credit, invoice finance and revenue-based finance. A seasonal business usually suits a revolving line or a short loan timed to its peak. A growing business that sells on credit usually suits invoice finance, which rises with sales. All funding is subject to status.

How do you choose between working capital lenders?

Start with why the cash runs short, then pick the facility type, then compare working capital lenders that offer it. Our guide to a working capital loan explains working capital finance in general. In short, there are four ways to fund the gap:

Four kinds of working capital finance
FacilityHow you repaySuits a cash gap caused by
Short-term loanFixed instalments over monthsA one-off cost, such as a stock order or a tax bill
Revolving line of creditDraw, repay and draw againGaps that open and close through the year
Invoice financeSettled when your customers payCustomers who pay on 30, 60 or 90 day terms
Revenue-based financeA share of future salesSteady card or online takings with uneven timing

Our guide to what working capital is shows how to measure the gap before you borrow, and a cash flow forecast shows when it opens.

Which working capital finance suits a seasonal business or a growing one?

The same amount borrowed behaves very differently depending on the pattern of your trade.

  • Seasonal business. Cash goes out before the busy season (stock, staff, marketing) and comes back during it. A revolving line lets you draw before the peak and clear it after, paying interest only on what you use where the lender charges that way. A short-term loan timed to finish after the peak also works, as long as the repayments do not land in the quiet months.
  • Growing business. Each new order needs cash before the customer pays, so the gap grows with sales. Invoice finance grows with your sales ledger, which a fixed loan does not. Revenue-based finance flexes with takings for a business paid by card or online.
  • Steady business with a one-off need. A short-term loan is usually the simplest, with a fixed cost and a known end date.
Match the repayment to the cash coming in

A daily or weekly repayment suits a business with daily takings. It strains one paid monthly or quarterly. Ask every lender how often it collects before you compare cost.

Which lenders offer short-term cash flow loans?

Short-term working capital loans are lump sums repaid over months rather than years. The table shows each lender’s matching products in its own published words, from its profile in our directory of UK business lenders. Lenders are listed alphabetically.

Repayment patterns differ widely: Little Business Loans takes daily, weekly or monthly instalments, SimplyFunded weekly or monthly, and Swishfund equal repayments across the term. Fleximize says its Flexiloan Lite is for businesses trading for at least 6 months, and Funding Circle publishes a shorter term loan of £10,000 to £750,000 over up to 12 months.

Which lenders offer revolving working capital facilities?

A revolving facility gives you a limit to draw on as needed. Our guide to business line of credit lenders compares these in more depth, including fees on undrawn balances.

iwoca charges interest only on what is drawn on its Flexi-Loan. Lenkie pays supplier invoices for you and describes its facility as uncommitted. Wayflyer’s Rolling Financing gives repeat access to its advances within a pre-approved limit on a 12-month contract.

Which lenders offer invoice finance for working capital?

Invoice finance advances money against unpaid invoices and is settled when your customers pay. It suits businesses selling to other businesses on credit terms. GOV.UK guidance says agreed payment dates between businesses should usually fall within 60 days, which is the kind of wait invoice finance is built to bridge.

Which lenders offer revenue-based working capital finance?

Revenue-based finance, including the merchant cash advance, is an advance repaid as a share of your future sales. Repayments rise in a strong month and fall in a quiet one. Most providers charge a single fixed fee rather than interest, so ask for the total repayable and how long it is likely to take.

Liberis takes a fixed percentage of daily sales subject to a monthly minimum, and YouLend takes a percentage of every sale plus a single fixed fee. A monthly minimum means repayments do not fall to zero in a very quiet month.

What do working capital lenders charge, and who can apply?

Costs vary by lender and applicant, and few working capital lenders publish rates. Compare offers on the total you repay and the cash that reaches your account, not the headline rate. Lenders quote cost as an interest rate, a fixed fee or a factor rate, and our guide on how to compare business loan lenders shows how to put them on the same footing.

Lenders commonly ask for:

  • Recent business bank statements, or open banking access.
  • A minimum trading history and turnover, which each lender sets.
  • A personal guarantee from the directors on most unsecured facilities.
  • Details of existing borrowing and any tax arrears.

On regulation, credit of more than £25,000 entered into wholly or predominantly for business purposes is exempt from consumer credit regulation under the Regulated Activities Order. Sole traders and small partnerships borrowing less may have a regulated agreement.

If the gap is a tax bill, ask HMRC first. GOV.UK says you may be able to set up a payment plan to pay in instalments, and that HMRC will check the plan is affordable. Our guide to HMRC Time to Pay covers how that works.

Common questions

A lender that funds day-to-day running costs rather than long-term assets, through short-term loans, revolving lines of credit, invoice finance or revenue-based finance. The facility is usually repaid within months or a few years.
Often a revolving line of credit drawn before the busy season and repaid during it, or a short-term loan whose repayments do not fall in the quiet months. Check how often each lender collects repayments.
If you sell to other businesses on credit, invoice finance grows with your sales ledger. If you are paid by card or online, revenue-based finance flexes with takings. A fixed loan does not grow as you do.
Among the lenders on this page, published short-term loan limits range from up to £20,000 to £1 million, and some revolving and invoice facilities go higher. What you are offered depends on your turnover and is subject to status.
Most unsecured working capital lending asks for a guarantee from the directors. Some invoice facilities publish lighter terms: Triver, for example, says it registers no charge against your business. Ask each lender.
Broadly, yes. Both fund the gap between paying costs and receiving income. Lenders use the names loosely, so check whether the product is a fixed loan, a revolving line or an advance against sales.
