Invoice Finance for Small Business: Options, Costs, and Alternatives

Updated May 2026 · 9 min read

You delivered the work. You sent the invoice. Now you wait 60 days for payment while your rent is due next week. Invoice finance solves this — but it comes at a cost. Here's what small business owners need to know.

The Small Business Cash Flow Problem

The average small business invoice is paid 45 days late (Xero research). That means a Net 30 invoice isn't paid until day 75. If you have staff, suppliers, or rent to pay in the meantime, you have a cash flow gap.

The typical small business timeline:

  1. Day 0 — Invoice sent (Net 30)
  2. Day 30 — Invoice due — client hasn't paid yet
  3. Day 45 — Average late payment (Xero data)
  4. Day 60–90 — Some invoices still unpaid

Invoice finance bridges this gap by advancing you most of the invoice value now, in exchange for a fee.

4 Types of Invoice Finance

1

Invoice Factoring

You sell your invoices to a factor at a discount. The factor collects payment directly from your client. You receive ~80% upfront and the balance (minus fees) when the client pays.

Pros

Fast cash — usually within 24–48 hours

Factor handles collections

Cons

Your client knows you're using a factor

Factor chases your client (can damage relationships)

Best for: Businesses comfortable with third-party collection

2

Invoice Discounting

Similar to factoring, but you retain control of your sales ledger and continue to collect payment yourself. The lender advances you funds against your invoices, which you repay when the client pays.

Pros

Confidential — client doesn't know

You keep control of client relationship

Cons

You still chase payments yourself

Usually requires larger invoice volumes

Best for: Established businesses with strong credit control

3

Selective / Spot Factoring

Choose individual invoices to finance, rather than committing your entire ledger. More flexible than traditional factoring.

Pros

No long-term commitment

Use only when you need it

Cons

Higher per-invoice fees

Not all providers offer it

Best for: Small businesses with occasional large invoices

4

Invoice Financing Platforms (Fintech)

Modern fintech platforms like Kriya, iwoca, and Bibby Digital offer fast digital applications, sometimes with same-day decisions.

Pros

Fast online application

Flexible amounts

No long-term contracts

Cons

Newer, less track record

May have higher rates for smaller invoices

Best for: Tech-savvy businesses wanting a fast, flexible option

Costs of Invoice Finance

Invoice finance is not free money — it's a loan against your invoices, with fees:

FeeTypical RangeWhat it covers
Service charge0.5–3%Admin, credit checks, account management
Discount charge1–3% per 30 daysThe 'interest' on the advance
Minimum monthly feeVariesIf you don't meet minimum volumes
Early repaymentSometimesIf you pay back early (less common)
Total cost example:A £10,000 invoice financed for 45 days at 2% service + 2% per 30 days discount = approximately £300–£400 in total fees (3–4% of invoice value). That's significant. Evaluate whether faster cash flow is worth the cost for your business.

When Invoice Finance Makes Sense

B2B invoices only (not consumer/B2C)
Established client relationships with creditworthy clients
Cash flow gap of 60+ days regularly
Invoice values large enough to justify 2–6% fees
Very small invoices (fees outweigh benefit)
Consumer invoices (factoring companies don't take B2C)
Disputed invoices (finance companies won't advance on disputed amounts)

💡 Better option first: Reduce your payment cycle

Before paying 2–6% in finance fees, try reducing the time between invoice and payment. Automated payment reminders can cut your average days-to-payment by 30–50%. That's free cash flow improvement — no fees, no credit checks.

Frequently Asked Questions

What is invoice finance for small businesses?

Invoice finance allows small businesses to unlock cash tied up in unpaid invoices. Instead of waiting 30–90 days for clients to pay, you receive most of the invoice value upfront from a lender.

How much does invoice finance cost?

Typical cost is 2–6% of invoice value, comprising a service charge (0.5–3%) and a discount charge (1–3% per 30 days).

Is invoice factoring right for my small business?

Invoice factoring works best for B2B businesses with established customers and invoices over £5,000. Not suitable for consumer invoices or very small invoice values.

What is the difference between factoring and discounting?

With factoring, the finance company chases your clients — your client knows about it. With discounting, you continue chasing clients yourself and it's confidential.
