multifi review: revolving business credit for established UK SMEs

multifi is a newer lender that set out to make business credit simpler. Its Flexi Credit product is a revolving facility: you draw funds, pay them back over a set schedule, then top back up when you need to, without filling in a fresh application each time. Smart Funding Solutions is an independent broker and is not part of multifi. multifi is one of the lenders on our panel, so we can compare it with other credit lines, loans and cash flow products. You can read more on multifi's own website.

01About multifi

multifi is the brand of Kactus Technologies Limited, a company based in London. It was founded in 2023 and says it has lent more than £40 million to UK businesses since then. In 2026 it announced a revolving funding line of up to £15 million from Fintex Capital to support further lending.

The business pitches itself as a transparent alternative to traditional lending, encouraging borrowers to look at the whole cost rather than a headline figure. It relies on Open Banking to assess applications quickly, which keeps paperwork to a minimum for many applicants.

02What multifi funds

multifi offers one core product, Flexi Credit, a revolving credit facility for working capital.

Because interest is only charged on what you actually use, and it falls as you repay, a revolving facility can work out more efficiently than borrowing a lump sum you do not fully need. The reload feature is the key difference from a standard short-term loan: once part of the balance is repaid, the facility can be used again.

Typical uses include buying stock ahead of busy periods, covering supplier payments, funding a new contract, or smoothing the gap between paying costs and getting paid. Our guide to revolving credit facilities explains how these products work across the market.

03Who multifi suits (and who it may not)

multifi's eligibility criteria are straightforward. You will need:

• A UK limited company or LLP. Sole traders are not eligible.
• At least one year of trading history.
• Annual revenue of at least £120,000.

It lists eligible sectors including manufacturing, retail, distribution, professional services, ecommerce and transport. That makes it a natural fit for product businesses that buy stock and need to fund it repeatedly. Online sellers might also find our page on ecommerce business loans useful.

multifi may be less suitable if:

• You are a sole trader or partnership.
• Your business is less than a year old or turns over less than £120,000.
• You need a long term loan for a major investment rather than recurring working capital.
• You would struggle with 12 monthly instalments after the drawdown, for example if income arrives in one or two large payments a year.
• Your business is based in Northern Ireland. multifi's website says businesses there are not eligible.

04What multifi looks at

multifi uses Open Banking to read your business bank data, which allows quick decisions. It says decisions are typically made the same day, and that 85 out of every 100 applicants get one within 24 hours. For facilities under £100,000, it says physical documents are not normally needed.

Beyond the headline criteria, lenders of this type typically look at:

• The level and consistency of money coming into the account.
• Average balances and any periods in overdraft.
• Existing loan or finance repayments.
• Business and director credit history.
• For larger facilities, recent accounts or management information.

Directors should expect to be asked for a personal guarantee, which is standard for unsecured lending to smaller companies.

05Pros and cons

Pros

• Revolving facility that can be reloaded without a new application.
• Interest charged only on what you draw.
• Fast decisions using Open Banking.
• Little or no paperwork for facilities under £100,000.
• Limits of up to £350,000, higher than many online credit lines.

Cons

• Limited companies and LLPs only.
• Needs a year of trading and £120,000 or more in revenue.
• Repayment over about a year means sizeable monthly instalments on a large draw.
• A newer lender with a shorter track record than banks and established lenders.
• Unsecured credit of this type can cost more than secured or bank borrowing, so compare the total cost.

06Applying through a broker vs going direct

Revolving credit lines, short-term loans, invoice finance and merchant cash advances can all solve a working capital problem. Which works best depends on how your business gets paid, how often you need funds and how much you can repay each month.
