What is causing the cash-flow pressure?

The cause of the gap can help determine which type of funding or action is worth exploring.

Waiting for customers to pay

Unpaid invoices are tying up working capital.

Cash flow varies and you need access to funds when required.

Compare business overdrafts →

Need a lump sum

You need a defined amount for working capital, stock or another planned cost.

Explore business loans →

Seasonal trading

Revenue changes significantly during the year.

Explore business loans →

Stock or supplier payments

You need funding before sales revenue arrives.

Explore working-capital options →

Payroll or tax timing

A short-term timing mismatch is putting pressure on available cash.

Compare business overdrafts →

Rapid growth

Sales are increasing but cash is tied up in stock, staff or customer terms.

Which option might fit?

These are educational considerations — not recommendations or guarantees of suitability.

Business overdraft may be worth exploring if:

  • you want a flexible borrowing buffer
  • cash-flow gaps are temporary
  • you do not need to draw the full facility at once
  • you are comfortable with possible account requirements / fees
Compare business overdrafts →

Invoice finance may be worth exploring if:

  • you invoice business customers
  • cash is tied up in unpaid invoices
  • funding needs rise and fall with sales
  • you understand fees and customer/debtor requirements
Explore invoice finance →

Working-capital loan may be worth exploring if:

  • you know the amount you need
  • the cost is planned
  • fixed repayments suit your cash flow
  • you want a defined borrowing term

Compare the total cost, not just the headline rate

Interest / EAR / APR

The headline borrowing rate where relevant.

Fees

Arrangement, renewal, service or platform fees may apply.

Repayment model

Flexible, sales-linked or fixed repayments affect cash-flow differently.

Total cost

The overall cost depends on how much you use, how long you use it and the product’s fee structure.

Different funding products may not be directly comparable using one metric.

Repayment structure matters

Users often compare rate but overlook how repayment mechanics affect day-to-day cash flow.

Flexible / revolving

You repay as the overdraft balance reduces.

Sales-linked

Repayment may rise and fall with customer sales or invoice collections.

Fixed instalments

Regular payments can make planning easier but create a fixed outgoing.

When borrowing may not fix the underlying issue

Borrowing can help with timing gaps, but repeated cash-flow pressure can be a sign that the underlying business finances also need attention.

  • persistent operating losses
  • consistently late-paying customers
  • margins that are too low
  • repeated reliance on short-term borrowing
  • poor cash-flow forecasting
  • large overdue tax liabilities
  • growth that is outpacing working capital

This is general education, not insolvency or legal advice.

Before using business finance for cash flow

  • What is causing the cash-flow gap?
  • How much funding do you actually need?
  • How long will the gap last?
  • What will the total cost be?
  • Are repayments fixed or linked to sales?
  • Does the product require a business bank account?
  • Is a personal guarantee required?
  • Is security required?
  • What happens if sales fall?
  • Are there renewal or arrangement fees?
  • Could the business manage without repeatedly refinancing?

Improving cash flow without borrowing

These steps can help, but they do not always remove the need for finance.

Invoice faster

Send invoices promptly and make payment terms clear.

Chase overdue invoices

Use consistent credit-control processes.

Review payment terms

Compare customer and supplier payment timing.

Build a cash buffer

Where possible, retain reserves for seasonal or unexpected costs.

Forecast regularly

Update cash-flow forecasts as sales and costs change.
