Invoice discounting lets you unlock cash from unpaid invoices, typically within 24 to 48 hours. The main advantages are faster cash flow, confidentiality, and funding that scales with your sales. The main disadvantages are fees, minimum turnover requirements, and the need to manage collections yourself.
It’s a popular option for established B2B businesses that want to improve working capital without affecting customer relationships. Unlike factoring, your customers won’t know you’re using it.
Below, we break down the advantages and disadvantages of invoice discounting in detail, and help you decide whether it’s right for your business.
How does invoice discounting work?
Invoice discounting lets you borrow against unpaid invoices, giving you access to cash before your customers pay. You raise an invoice as normal, send it to the finance provider, and receive an advance (typically 80% to 90% of the invoice value) within 24 to 48 hours.
You stay responsible for collecting payment. Once your customer pays, the provider releases the remaining balance, minus their fees.
For example, a wholesaler owed £40,000 by retail clients could unlock up to £36,000 almost immediately, using the funds to restock or cover operating costs rather than waiting 60 days for payment.
Because you manage collections yourself, your customers don’t need to know a finance provider is involved. This confidentiality is one of the main differences between invoice discounting and invoice factoring, where the provider takes over payment collection directly.

Advantages of invoice discounting
Invoice discounting suits B2B businesses that invoice on credit terms and want to get paid faster without involving their customers.
1. Improved cash flow
Rather than waiting 30, 60, or 90 days for payment, you can access up to 90% of an invoice’s value within 24 to 48 hours. For example, a manufacturing business owed £80,000 by retail clients could release up to £72,000 almost immediately – funds that can go towards payroll, stock, or day-to-day operations.
2. Confidential facility
Unlike factoring, invoice discounting is typically confidential. Your customers won’t know you’re using finance, and you stay in control of chasing payments and managing the relationship. This can be important if you want to avoid any perception that your business is under financial pressure.
3. Funding that grows with your sales
As your turnover increases, so does your available funding. The facility is linked to your sales ledger, so the more you invoice, the more working capital you can access. This makes it a flexible option for businesses going through a growth phase or managing seasonal peaks.
4. No need for additional security
Your invoices act as the security for the facility, so you won’t need to offer property, equipment, or other assets as collateral. This can make invoice discounting more accessible than traditional loans, and leaves your other assets free for different purposes.
5. You stay in control
You retain full responsibility for credit control and collections, which means you manage customer relationships on your own terms. For businesses with an established finance team or robust processes in place, this can be a significant advantage over factoring.
Disadvantages of invoice discounting
Invoice discounting isn’t for everyone. Depending on your size, sector, and how you manage credit control, some of these drawbacks might outweigh the benefits.
1. Fees reduce your margin
You’ll pay a service fee and a discount charge on the funds you draw down, which means you won’t receive the full value of each invoice. For businesses operating on tight margins, these costs can add up. It’s worth comparing providers and understanding exactly what you’ll be charged.
2. You’re still responsible for collections
Unlike factoring, where the provider chases payments on your behalf, invoice discounting leaves credit control with you. If you don’t have the time or resources to manage this effectively, late payments from customers can create problems – both for your cash flow and your relationship with the finance provider.
3. Not always available to smaller businesses
Many providers require a minimum turnover, often around £500,000 to £1 million, before they’ll offer invoice discounting. Smaller or newer businesses may find it harder to access, or may face higher fees. In these cases, selective invoice finance or a business loan might be a better starting point.
4. Relies on your customers paying
The facility depends on your customers settling their invoices. If a customer pays late or defaults, you’ll still owe the provider, unless you have a non-recourse arrangement in place.
5. Can become a dependency
Because invoice discounting is tied to your sales ledger, it’s easy to rely on it as an ongoing source of working capital. That’s fine if it suits your business model, but it’s worth having a clear view of when and how you might reduce your reliance on the facility over time.
What does invoice discounting cost?
Most invoice discounting facilities involve two charges: a service fee applied to your gross turnover, and a discount charge on the funds you draw down. The discount charge works like interest — it accrues daily on whatever you have drawn from the facility and is calculated at an annualised rate.
Using a business with £100,000 of outstanding invoices on 30-day payment terms as a working example:
| Fee type | Typical rate | Cost on £100,000 invoices (30 days) |
|---|---|---|
| Service charge | 0.2% to 0.5% of invoice value | ~£300 |
| Discount charge (on 85% advance drawn for 30 days) | Base rate + 2% to 4% p.a. | ~£490 |
| Total cost for the month | ~£790 |
Figures are indicative at a 0.3% service charge and 7% p.a. discount rate. Actual rates depend on your turnover, debtor quality, payment terms, and the provider.
The effective cost tends to fall as the facility grows. A business turning over £5 million a year will typically secure a lower service charge rate than one turning over £500,000, because the provider’s fixed costs are spread across a larger ledger. Some providers also charge a minimum monthly fee, which can make smaller facilities disproportionately expensive.
Invoice discounting vs invoice factoring
Invoice discounting and invoice factoring both release cash tied up in unpaid invoices, but they work differently. The key distinction is who collects the money from your customers, and whether your customers are aware of the arrangement.
| Invoice discounting | Invoice factoring | |
|---|---|---|
| Confidentiality | Yes — customers do not know | No — customers pay the lender directly |
| Who collects payments | You | The lender |
| Cost | Lower | Higher (includes credit control service) |
| Control over ledger | You retain full control | Lender manages collections |
| Bad debt protection | Usually not included | Often available (non-recourse) |
| Typical minimum turnover | £500,000+ | Lower — more accessible for smaller businesses |
| Best for | Established businesses with strong internal credit control | Businesses wanting to outsource collections |
If keeping the arrangement confidential matters and you have capable internal credit control, invoice discounting is usually the better fit. If you want to hand over collections entirely, or your business does not have the resource to chase debtors effectively, factoring may suit you better despite the higher cost.
Is invoice discounting right for your business?
Invoice discounting is likely the right choice when:
✓ Your business invoices other businesses (B2B) on credit terms of 30, 60, or 90 days
✓ You have strong internal credit control and chase payments effectively
✓ Confidentiality matters – you do not want customers to know you use a finance facility
✓ Your annual turnover is £500,000 or above
✓ You need funding that scales automatically as your sales and invoicing grow
✓ You want to bridge the gap between raising invoices and receiving payment without taking on a traditional loan
An alternative may suit you better when:
✗ Your annual turnover is below £500,000 – options exist but are more limited and can be more expensive
✗ You want to outsource credit control and collections – invoice factoring handles this for you
✗ Your customers are slow or unreliable payers – this increases your cost and risk under a discounting facility
✗ Your business invoices consumers rather than businesses – B2C businesses are generally not eligible
✗ You need a lump sum for a specific purpose rather than ongoing working capital – a business loan may be more appropriate
Is invoice discounting right for you?
Invoice discounting can be a practical way to improve cash flow without giving up control of your customer relationships. It tends to work best for established B2B businesses with a solid sales ledger, reliable customers, and the internal resource to manage credit control.
That said, it’s not the only option. If you’re a smaller business, need more flexibility, or would prefer someone else to handle collections, factoring or a different type of invoice finance might suit you better.
