Revenue-Based Finance in the UK: Juice, Wayflyer, Outfund & More Compared

Most UK "RBF" products fall into one of two camps. The difference matters more than any headline rate.

The trap with flat fees is that they look cheaper than they are. Take a £100k advance with a 6% fee, repaid in equal daily amounts over four months. You pay £6k, but you only hold the full £100k on day one. On average you hold only about half of it, so as an annual percentage rate (APR) that works out at about 42%.

Compare that with a credit line charging 1.5% a month, but only on what you've drawn and only while it's drawn: an APR of about 20%. Use it the same way, drawing £100k and repaying it evenly over four months, and you'd pay about £3k instead of £6k. Any part of your limit you don't use costs nothing. Same "headline" feel, very different cost. Always ask each lender for an annual percentage rate, or work one out, before you compare.

How we worked these out: both figures are APRs, which annualise the cost with compounding, so they compare like for like. A flat fee costs more than it looks because you repay as you go: you hold the full £100k on day one but only about half of it on average. The flat-fee example assumes equal daily repayments over four months; repay faster and the APR rises, slower and it falls. These are illustrations, not quotes.

Every figure below comes from the lender's own website. Lenders are sorted by the smallest amount you can borrow. Where a lender doesn't publish a number, we say so rather than guess.

Wayflyer lends £10k to £20m to UK ecommerce brands for one fixed fee, typically 5–10% of the advance. On its own example, a $100k advance with a 6% fee means repaying $106k, collected as a share of daily sales.

There are no application, setup, maintenance, late payment or early repayment fees, and its UK page says no personal guarantee is required. Best for: a defined push, such as a big stock order before Q4 or a launch campaign, where you know the payback.

Outfund funds £10k to £500k for businesses with around £10k in monthly sales and at least six months' trading. You choose between repaying as a share of sales or in fixed instalments, and you can pick the term and level of security. Offers arrive within three days. Best for: growing brands that want a fixed cost and flexible repayments.

Swishfund isn't ecommerce-specific, but it's a fast option for limited companies with £50k+ turnover and at least one set of filed accounts. Loans run up to 24 months at 1.1–3% a month plus a one-off arrangement fee. You can repay early without a settlement fee, though interest runs to the end of that month.

Juice's main product, Juice Flex, is a revolving credit facility from £50k to £1m. You draw what you need, repay, and draw again. There's no expiry and no mandatory top-ups, and you pay a flat monthly fee only on what you've drawn.

Each draw can be repaid over up to 24 months, or you can pay just the monthly fee and repay the draw at the end. There's no debenture under £150k and no penalty for repaying early. Smaller businesses can look at Juice Now, which lends up to £150k repaid monthly over up to 12 months.

One thing to know: this is a credit line, not classic revenue-based finance. Each draw has agreed repayment terms rather than a share of sales. Best for: established brands that need capital again and again, such as stock every season or ad spend every month.

Uncapped lends £100k to £2m through fixed-term loans and a line of credit, for a fixed fee agreed upfront. You'll need at least £100k in monthly revenue (£10k for its Amazon seller product) and six months' trading. It asks for no personal guarantee and gives decisions within 48 hours. Best for: established brands raising six or seven figures.

Shopify Capital offers UK merchants a cash advance repaid from a share of daily sales. It's invitation-only: if you're eligible, the offer appears in your Shopify admin. Amazon sellers may also see cash advance offers in Seller Central, provided through its partner YouLend. These are easy to accept, but you can't negotiate the terms.

Here's the part most funding guides skip: RBF only pays off if the money turns into profitable revenue fast. Borrow £100k at 8% and pour it into ads with a weak return, and you've paid for the privilege of shrinking your margin.

The brands that get the most from growth capital already know their numbers: customer acquisition cost, payback period, contribution margin by channel. That matters to lenders too: Wayflyer, for one, sets its fee based on your financial health and trading history.

That's where we come in. At Refiner, we build the growth strategy, marketing delivery and reporting that make every pound of funding work harder. Thinking about raising growth capital? Talk to us first, and make sure the engine is ready for the fuel.
