CoreFi is a broker, not a lender. We do not set rates and lenders make all credit decisions.
In short: Working capital finance covers short-term funding gaps for UK businesses through revolving credit, overdraft alternatives, invoice finance or short-term loans, usually £5k to £250k. We match you to the facilities most suited to your cash flow pattern and trading history.
Working capital finance funds the gap between when money goes out and when it comes back in. That gap is what kills otherwise healthy businesses, and the right product depends on what is creating it.
If the problem is slow-paying customers, invoice finance is usually the answer. A lender advances up to 90% of the face value of unpaid invoices, then collects when your customer pays and releases the balance less their fee. Instead of waiting 60 or 90 days, the cash is with you within 24 to 48 hours of raising the invoice.
If the need is more general, a revolving credit facility works like a business overdraft: a limit you draw on and repay repeatedly, paying interest only on what you have drawn. That suits seasonal peaks, a large stock buy, or a payroll month where a big contract payment is running two weeks late.
Short-term loans sit between the two. A fixed amount for a fixed period, usually three to eighteen months, suited to a single known outlay rather than an ongoing fluctuating need.
Lenders price working capital on turnover, trading history and the quality of your debtors. The high street has pulled back its appetite here, so the lenders we place with regularly are the challenger banks and specialist facilities that move faster and hold more flexible credit criteria. We do not decide the rate or the approval, the lender does, but putting the right product in front of the right lender is where the work is done.
Key Benefits
- Invoice finance advances up to 90% of unpaid invoices within 24 to 48 hours of raising them, so your debtor book stops being a cash flow problem
- A revolving credit facility lets you draw and repay repeatedly against a set limit, and you pay interest only on what you have drawn rather than the whole facility
- Short-term loans suit a single known cost, stock purchase or payroll gap: fixed amount, fixed term, no ongoing facility fee
- Challenger banks and specialist lenders hold better appetite here than the high street right now, which is where we focus the search
Frequently Asked Questions
What counts as working capital finance?
Anything that funds day-to-day operations rather than a long-term asset. Revolving credit, overdraft alternatives, invoice finance, merchant cash advances and short-term loans all qualify.
Revolving credit or a short-term loan?
A revolving facility suits fluctuating, ongoing needs where you draw and repay repeatedly and pay interest only on what you use. A short-term loan suits a single known cost where you want a fixed repayment schedule and you already know how much you need.
How fast can it be arranged?
Invoice finance can be live within a few days once your debtor book is reviewed. Revolving credit facilities typically take one to two weeks from application to drawdown once your accounts and bank statements are in. Timelines depend on the lender and the case; old accounts or debtors concentrated in a single customer will slow it down.
