Funding for UK Technology and SaaS Companies: Beyond Equity

Why tech companies historically underuse debt

Technology businesses — particularly software companies — often have limited hard assets and negative cash flow during growth phases, making them poor fits for traditional asset-secured lending. Combined with the availability of venture capital and angel finance in the UK tech ecosystem, many founders default to equity without seriously evaluating debt alternatives.

This has started to change. Revenue-based lending, venture debt, and R&D tax credit financing have developed specific products for tech businesses. For profitable or near-profitable SaaS companies, debt can be materially cheaper than equity dilution.

Lending against recurring revenue (ARR)

SaaS and subscription businesses with demonstrable annual recurring revenue — contracted, multi-year, with low churn — can access facilities based on ARR multiples. Lenders assess net revenue retention (does the ARR base grow or shrink without new sales?), gross margin, and sales efficiency to determine how much of the ARR base is stable enough to lend against.

These facilities are typically structured as term loans or revolving facilities with covenants tied to ARR maintenance. A decline in ARR below a threshold can trigger a covenant breach, so directors should model realistic downside scenarios before committing to an ARR-covenant structure.

R&D tax credit advance lending

UK companies with qualifying R&D expenditure can claim HMRC R&D tax credits — either as a cash repayment (for loss-making companies claiming under the SME scheme) or as a reduction in corporation tax liability. Processing these claims can take six to twelve months.

R&D tax credit loans allow a company to draw against the anticipated refund value before HMRC processes the claim. The lender effectively advances the refund early, repaid when HMRC pays. This is a bridge, not ongoing working capital — and only viable where the R&D claim is correctly prepared and the company's advisers are confident in the amount. Confirm claim value with your tax adviser before approaching a lender.

Venture debt and convertible facilities

Venture debt — term loans typically provided alongside or following an equity round — allows a company to extend its runway or fund specific initiatives without further dilution. It is not a substitute for equity where the company is pre-revenue; it is complementary to equity where there is demonstrated traction.

Convertible loan notes are a hybrid: the lender can convert to equity at a future round under agreed terms. These are financing instruments that carry legal and shareholder implications; directors should take legal advice before issuing convertibles, particularly regarding EIS/SEIS eligibility for other shareholders.

Working capital for growth phases

Even profitable SaaS businesses can face cash flow pressure when growth accelerates — sales commissions are paid immediately, but annual subscription revenue spreads over twelve months. A working capital facility allows the company to invest in sales and marketing ahead of the subscription revenue that will service it.

Directors should model customer acquisition cost (CAC) recovery periods carefully: if the average customer takes eighteen months of revenue to repay their acquisition cost, a working capital facility needs to be sized to fund at least that pipeline duration comfortably.
