Quick answer: what a cash flow loan is

A cash flow loan is short-term finance designed to cover day-to-day operational needs rather than long-term capital projects. It’s sometimes called working capital finance and includes a variety of products that release money quickly so your business can continue to run smoothly while waiting for invoices, seasonal sales or one-off payments.

Typical borrowing amounts start from around £10,000 and can go to several hundred thousand pounds or more depending on product and business strength. Terms vary by product — from 30 days (or shorter) up to 36 months for some facilities. The right option depends on how quickly you need cash, how you’ll repay it, and what security you can offer.

Common types of cash flow finance

Short-term business loans / working capital loans

Single lump-sum loans repaid over a short fixed term. Specialist online lenders and alternative finance providers can issue offers quickly for limited companies with clean accounts. These are useful for bridging a specific gap or paying for a one-off cost.

Overdrafts and lines of credit

Revolving facilities that let you draw up to an agreed limit — good for ongoing flexibility. Bank overdrafts are familiar to many businesses; specialist providers also offer lines of credit with quick access if your profile suits them.

Invoice finance & factoring

Invoice finance releases a percentage of unpaid invoices (commonly 70–90%) so you don’t wait for customers to pay. Factoring can include collections services. Setup can be same-day to a few days for smaller facilities once invoices and customer credit are verified.

Merchant cash advances

Advance against future card takings — funds can be very fast (hours to a day), but repayments are taken from daily card receipts and costs can be higher than other options.

Trade finance / supply chain finance

Designed for contract-heavy trades such as construction or manufacturing — helps fund materials and progress payments against purchase orders or contracts.

Who uses cash flow loans?

Cash flow finance is widely used by SMEs across sectors. Common users include:

• Construction businesses needing materials ahead of payment milestones
• Hospitality and retail businesses managing seasonal peaks
• Manufacturers bridging supplier payments
• Recruitment agencies covering payroll before client invoices are settled
• Online retailers and wholesalers building stock ahead of demand

Micro case examples: a café funds a refurbishment before summer trade; a supplier takes invoice finance to cover wages while waiting 60-day customer terms.

How lenders assess eligibility

Lenders and brokers look at a mix of financial data, business history and sector risk. Typical checks include:

• Business legal status and trading history (many lenders prefer limited companies trading for at least 6–12 months)
• Annual turnover and recent cash conversion — stronger turnover improves options
• Bank statements (usually 3–12 months)
• Management accounts and VAT returns where available
• Director and business credit history
• Evidence of contracts, purchase orders or invoices (especially for invoice finance or contract-backed solutions)
• Security or guarantees — some lenders require a personal guarantee or asset security for larger facilities

Initial enquiries often use soft credit checks or Open Banking for fast assessment; full credit or affordability checks typically occur later in the process when you decide to proceed. That means you can get tailored quotes without affecting your credit score.

How soon can UK SMEs secure a cash flow loan?

Timescales vary by product, paperwork and lender. Here’s a practical guide:

• Within hours: Merchant cash advances, some online short-term lenders and instant invoice finance for repeat customers (if bank data and invoices are ready).
• 24–72 hours: Many alternative lenders and brokers can deliver indicative offers for straightforward limited companies with clear bank statements and recent accounts.
• 3–14 days: Invoice finance set-ups, larger working capital facilities, or where a little more verification is required.
• 2–6 weeks: Traditional bank lending or larger secured loans needing property or asset valuations and legal work.

Product → typical time to first offer → typical funding time:

• Merchant cash advance → hours → same day to 48 hours
• Online short-term loan → 24–72 hours → 24–72 hours
• Invoice finance → 1–7 days → 1–14 days
• Bank overdraft/secured loan → 1–3 weeks (offer) → 2–6+ weeks

Speed-up tips:

Costs, risks and benefits

Pros:

• Fast access to cash when you need it
• Flexible products to match sales cycles and invoice timings
• Can prevent disruption to payroll, suppliers and operations

Cons / risks:

• Faster products can come with higher fees or APRs (merchant cash advances and some online lenders)
• Repayment schedules can reduce available cashflow if not carefully planned
• Some lenders may ask for personal guarantees or take security over assets

Example comparison (illustrative only — actual rates vary):

• Invoice finance: fees 1–3% per invoice month + facility charges; effective cost depends on advance rate and fees
• Short-term online loan: fixed daily/weekly repayments — APRs vary widely; compare total cost of credit

Note: Costs and eligibility vary by lender. You’ll receive personalised quotes showing exact costs and terms once matched.
