UK invoice finance: how quickly can I access cash tied up in unpaid invoices?

Summary — quick answer: With the right product you can access cash from unpaid invoices in as little as 24 hours.

Ongoing facilities such as invoice factoring or discounting typically deliver funds within 24–72 hours after an invoice is approved, but first-time facility setup usually takes 1–3 weeks due to KYC, credit and contract steps.

What is invoice finance and why speed matters

Invoice finance lets you unlock cash tied up in unpaid invoices so you can pay suppliers, staff or take a new opportunity without waiting for customers to pay. Main types are invoice factoring (a lender manages or chases debtor payments), invoice discounting (you retain control of collections) and spot/one-off factoring (sell single invoices for fast cash). For many UK businesses the difference between getting paid in 24 hours or weeks can determine whether a job goes ahead, payroll is met or a seasonal opportunity is seized.

The short answer: typical timescales by product

  • Spot factoring / one-off invoice purchase: 24–72 hours once due diligence and debtor checks are complete. Ideal for one-off cash needs.
  • Invoice factoring (ongoing): 24–72 hours after each invoice is uploaded and approved; initial facility setup 1–3 weeks for new customers.
  • Invoice discounting (confidential): If you already have a facility, drawing down can be 48 hours to 7 days; new setups usually 1–3 weeks.
  • New long-term facility (first-time users): 1–3 weeks. This covers KYC, trading checks, credit assessments and contracts.
  • Platform/fintech marketplace finance: Same-day to 48 hours in many cases — verification speed varies by platform.

These are typical ranges — exact times depend on documentation, debtor credit checks and the provider’s onboarding process.

What determines how fast you get paid?

Speed depends on a mix of product choice, paperwork and the parties involved. Key factors:

  • Product type: Spot factoring is fastest; full facilities need more setup.
  • Existing facility: If you already have an active facility with a provider, subsequent draws are much quicker.
  • KYC / Anti‑money‑laundering checks: Essential and can take from a few hours to several days depending on responses.
  • Debtor creditworthiness: Lenders assess your customers’ ability to pay; high-risk debtors slow approval.
  • Debtor notification / approval: Factoring where debtors must be informed or authorised can add time; confidential discounting avoids this delay.
  • Invoice quality: Clean invoices with clear terms, correct contacts and confirmed delivery speed up the process.
  • Industry sector: Certain sectors (e.g., construction with retentions) require extra checks.
  • Lender processing times and working hours: Weekends, holidays or manual underwriting create delays; digital providers are faster.

Quick tip: Have your last three months’ sales ledger and basic company documents ready to accelerate approval.

Step-by-step timeline: from enquiry to funds

  1. Enquiry & pre-screening (minutes–hours): Complete a short enquiry form so we can match you to suitable lenders and brokers. This is not an application.
  2. Lender/broker contact (same day–48 hours): A matched partner will request documents and confirm product options.
  3. KYC & credit checks (24 hours–5 days): ID for directors, company verification and debtor credit checks occur here.
  4. Contract and account setup (same day–3 days): E-signatures speed this up; some providers require bank mandate or portal access.
  5. Invoice submission & approval (same day–72 hours): Upload invoices to the provider portal; approval times vary by debtor checks and product.
  6. Funds release (same day or next working day): Advance (commonly 70–90% of invoice) is paid once an invoice is approved.

Costs vs speed: what to expect

Faster funding commonly comes at a higher price. Providers charge in different ways:

  • Discount/finance rate: percentage charged on the invoice value for the time the facility funds are used.
  • Advance rate: the % of an invoice paid upfront (typically 70–90%).
  • Fees: setup/arrangement fees, monthly service fees, debtor management fees (for factoring).

Example: sell a £10,000 invoice with 85% advance. You receive £8,500 quickly. When the debtor pays, you get the remaining £1,500 minus fees and interest. Exact figures vary — always check the lender’s terms.

Who invoice finance suits & when faster options are best

Invoice finance is useful for limited companies and growing SMEs that need working capital. Typical use cases include:

  • Seasonal businesses needing stock or staffing ahead of peak.
  • Businesses tendering for work and needing cash to start projects.
  • Companies with strong sales but slow-paying customers.
  • Firms expanding and who want predictable cashflow without taking on extra long-term debt.

Use spot factoring for one-off urgent needs; choose a facility (factoring or discounting) if you need ongoing working capital. UK Business Loans can match you to providers offering suitable options for sums from around £10,000 upwards.
