The Core Difference
Both invoice factoring and invoice discounting are forms of invoice finance — they allow you to access cash tied up in unpaid invoices rather than waiting 30, 60, or 90 days for your customers to pay. The key difference is who manages the credit control process.
| Invoice Factoring | Invoice Discounting |
|---|
| Who chases debtors? | Finance company | You |
| Do customers know? | Yes | Usually no (confidential) |
| Admin responsibility | Finance company | Your business |
| Suitable for turnover | £100k–£2m+ | £500k–£50m+ |
| Typical service charge | 0.75–2.5% of turnover | 0.1–0.5% of turnover |
| Discount fee | 0.5–3% above base rate | 0.5–2.5% above base rate |
How Invoice Factoring Works
- You issue an invoice to a customer
- You upload the invoice to the factor’s platform (or batch-upload your sales ledger)
- The factor advances typically 80–90% of the invoice value within 24 hours
- The factor manages all credit control — sending reminders, chasing, and collecting payment directly from your customer (usually paying into a trust account)
- When the customer pays, the factor releases the remaining 10–20%, minus their fees
- Your customers pay the factor directly and are aware of the arrangement
How Invoice Discounting Works
- You issue invoices and upload them to the finance company’s platform as normal
- The finance company advances 80–90% of the verified invoice value
- You continue to manage your own credit control — your customers pay your bank account as normal
- You notify the finance company as invoices are paid, and the remaining 10–20% is released
- Your customers are unaware of the arrangement (under confidential invoice discounting)
Confidentiality — Why It Matters
For many businesses, keeping invoice finance confidential is commercially important:
- Some customers — particularly large corporates or public sector bodies — view factoring as a sign of financial fragility and may reassess their relationship with the supplier
- In competitive markets, revealing that a competitor has the stronger financial position can affect tendering
- Some contracts prohibit assignment of receivables to a third party (a common contractual restriction worth checking)
Invoice discounting resolves all three concerns. Factoring, by contrast, requires the finance company to send payment instructions to your customers, making it visible.
Which Is Right for Your Business?
Choose Invoice Factoring When:
- Your business turns over under £500,000 — discounting facilities often have minimum volume requirements
- You have limited internal credit control resource — factoring includes a collections service as part of the package
- Your debtors are slow payers and you need professional collection support
- You’re growing quickly and can’t yet afford a dedicated finance team
- Your customers are used to factoring in your industry (common in recruitment, construction sub-contracting, and transport)
Choose Invoice Discounting When:
- Your business turns over £500,000+ with a reasonably diversified debtor book
- You have strong internal credit control — you already collect effectively and don’t need the factor’s help
- You want to keep the arrangement confidential from customers
- Your customer relationships are sensitive to third-party involvement
- You want to retain the commercial relationship with your customer including the payment conversation
Costs in Detail
Factoring Costs
Service charge: 0.75–2.5% of invoice value. Covers credit control, ledger management, and collections.
Discount (interest) charge: Typically base rate + 1.5–4%, applied to the funds you’ve drawn. At current base rate of 4.5%, you’d pay approximately 6–8.5% per annum on outstanding advances.
Example: £50,000 invoice, 75 days to payment, advance rate 85%, service charge 1.5%, discount rate 7.5%:
- Advance: £42,500
- Service charge: £750 (1.5% of £50,000)
- Discount fee: £42,500 × 7.5% × (75/365) = £654
- Total cost: £1,404 (2.8% of invoice value)
Invoice Discounting Costs
Service/admin fee: 0.1–0.5% of turnover annually — far lower than factoring because you manage credit control.
Discount charge: Base rate + 1–3% on drawn amounts.
Example (same invoice):
- Advance: £42,500
- Admin fee (annual, pro-rated): ~£150
- Discount fee: £42,500 × 6% × (75/365) = £524
- Total cost: £674 (1.35% of invoice value)
The difference in cost is real but narrows when you account for the credit control service factoring includes.
What to Watch Out For
- Minimum fee clauses — some factors charge a minimum monthly fee regardless of invoice volume; relevant if your business is seasonal
- Concentration limits — if one customer represents more than 30–40% of your ledger, lenders may restrict how much they’ll advance against that debtor
- Bad debt protection — weigh up non-recourse factoring if you trade with financially weaker customers
- Exit clauses — most facilities are 12-month rolling contracts with 3–6 months’ notice required; check the exit terms before you sign
