Invoice Factoring vs Invoice Discounting: Which Is Better for Your Business?

How Invoice Factoring Works

Invoice factoring works by selling your outstanding invoices to a specialist finance company (the factor) at a discount. When you raise an invoice and submit it to the factor, they advance you a percentage of the face value — typically 70-90% — within 24-48 hours. The factor then takes over responsibility for collecting payment from your customer. When your customer pays, the factor releases the remaining balance to you minus their fees.

The key distinguishing feature of factoring is that the finance provider becomes visibly involved in your credit control process. Invoices are typically re-addressed or include a notice of assignment directing payment to the factor’s bank account. Your customers will receive payment reminders, statements, and chasing calls from the factoring company — not from you. For many businesses, particularly those in construction, recruitment, or manufacturing with high invoice volumes and many smaller customers, this is a practical arrangement that removes significant administrative burden.

Factoring agreements are typically whole-ledger — meaning all your invoices pass through the facility, not just selected ones. The factor monitors your debtor book, sets credit limits per customer, and manages the collection process end to end. Non-recourse factoring — where the factor also takes on bad debt risk — is available at a higher cost and provides an effective form of trade credit insurance alongside the cash flow facility.

How Invoice Discounting Works

Invoice discounting delivers the same core benefit — early access to cash tied up in unpaid invoices — but keeps the arrangement entirely confidential. You raise your invoices and notify the discounting provider, who advances you a percentage of the ledger value. Crucially, you continue to collect payment from your customers yourself, in exactly the same way as you always have. Your customers never know a finance provider is involved.

Because the discounting provider is trusting you to manage collections effectively and protect the debtor book they’ve advanced against, they apply more rigorous entry criteria. Most providers require annual turnover of at least £500,000, a proven track record of collecting debts within terms, and a finance function capable of maintaining accurate, reconciled ledger records. The reduced service requirement — you’re doing the collections work, not them — means fees are lower than factoring.

Discounting is the preferred model for businesses where client relationships are sensitive to third-party involvement: law firms, accountancy practices, marketing agencies, and high-value manufacturing businesses where long-standing relationships are commercially critical. In these sectors, having a lender chase your clients for payment could cause genuine reputational or relationship damage.

What Will It Cost? Worked Examples

Example: £1.5 million annual B2B turnover, 60-day payment terms

Under factoring at 2% of invoice value (service fee 1.2% plus discount charge 0.8%), the annual cost on £1.5m of invoices is £30,000. In return, you receive an ongoing advance of approximately £200,000 (roughly 80% of the typical ledger balance), and the factor handles all collections.

Under invoice discounting at 1.1% of invoice value, the annual cost on the same £1.5m is £16,500 — a saving of £13,500 per year compared to factoring. However, you are responsible for all credit control, and the minimum turnover threshold means this option is not available to smaller businesses. If your internal collections function is well-resourced, discounting is significantly cheaper for the same cash flow benefit.

The bad debt scenario: A customer owing £25,000 goes insolvent. Under non-recourse factoring, the factor absorbs the loss — your £25,000 is protected. Under discounting, the loss typically falls to you. For businesses with concentrated debtor exposure, the bad debt protection element of factoring may be worth the higher fee in itself.

Which Is Better for Your Situation?

You run a recruitment agency with 200 clients and no dedicated finance person. Factoring is the natural fit. High invoice volumes, many customers, and limited internal resource make outsourcing collections genuinely valuable. The slight premium on fees is easily justified by the time saved and the working capital unlocked.

You run a twelve-person marketing agency with six long-standing retainer clients. Discounting is almost certainly the right answer. Your clients are sophisticated, your relationships are key to your business model, and having a third party calling to chase payment would be actively harmful to those relationships. Your turnover likely exceeds £500,000 and you have the finance function to manage collections properly.

Your business is growing fast and cash flow can’t keep up with orders. Both products can help, but factoring is more accessible at lower turnover levels. If you’re at £200,000 turnover and growing, factoring gets you immediate access to working capital without the turnover threshold. You can graduate to discounting later as turnover increases.

You have two large customers who represent 70% of your debtor book. Non-recourse factoring with credit limits on those two accounts provides genuine protection against concentration risk. If either of those customers fails, you’re covered. Discounting typically doesn’t include this protection.

The Bottom Line

Factoring and discounting are two delivery mechanisms for the same underlying product: unlocking cash from unpaid invoices. The right choice depends on three factors: your turnover level (discounting has a floor), your client relationship sensitivity (discounting is invisible), and your internal credit control capability (discounting requires you to manage collections yourself).

Most smaller businesses start with factoring and find it genuinely transformative for working capital. As they grow, those with strong finance functions and confidentiality-sensitive client relationships migrate to discounting. The two products are not competing — they are sequential stages of the same financing journey.
