Invoice factoring is a form of invoice finance where a funder advances most of the value of your unpaid business invoices, typically around 80% to 90%, and then runs your sales ledger and collects payment from your customers. It is usually disclosed to customers, can include bad-debt protection, and suits younger or smaller B2B businesses without their own credit control team.
This page is for owners and finance leads of B2B businesses that invoice other businesses on credit terms and would rather hand the chasing to someone else. Invoice factoring releases cash tied up in unpaid invoices and, unlike most other forms of invoice finance, the funder also runs your sales ledger and collects the money from your customers. Smart Funding Solutions is a broker, not a lender. We search lenders on our panel of 300+ for factoring facilities from around £10,000 to £500,000+, with larger facilities available in suitable cases.

Invoice factoring is a facility where a funder buys your approved invoices, pays you most of their value straight away and then collects payment from your customers on your behalf. The cycle repeats every time you raise an invoice, so the cash available grows as your sales grow.
The defining feature is that the funder runs the sales ledger. Your customers know a finance company is involved because they pay it directly. This is called a disclosed facility, and it is the normal arrangement for factoring. If keeping the funder out of sight matters more to you than outsourcing collections, see invoice discounting instead.
The difference is who carries the loss if a customer never pays: with recourse factoring you do, and with non-recourse factoring the funder or its credit insurer does, within agreed limits. This choice affects both the cost and the protection you get.
Under a recourse facility, if an invoice is not paid within an agreed period (often 90 to 120 days from the invoice date, depending on the lender), the factor can ask you to repay the prepayment or replace it with a newer invoice. Recourse factoring is the more common and usually the cheaper structure, because the funder is not taking the credit risk on your customers.
Non-recourse factoring includes bad-debt protection, normally through credit insurance arranged by or through the funder. If a customer becomes insolvent, the insured portion of the debt is covered up to a credit limit set for that customer. It is not blanket protection. Cover usually applies only to approved customers, within each customer's limit, and often only to insolvency rather than to disputes over the quality of your work. There is normally a first-loss share that you bear. Read the policy terms as closely as the factoring agreement itself.
Some businesses buy credit insurance separately and assign it to the funder, which can suit firms that already have a policy in place. Either way, bad-debt protection is a cost, so it makes most sense where a single customer failure would do serious damage.
Invoice factoring suits younger and smaller B2B businesses that sell on credit terms, are growing faster than their cash allows and do not have an in-house credit control team. Lenders often accept businesses with a short trading history, because the funding is assessed largely on the quality of the invoices and the customers who owe them.
Typical users include:
Factoring is usually a poor fit where:
A new factoring facility typically takes one to three weeks from application to first drawdown, though it depends on the lender and the case. The timetable moves with how quickly you supply the documents above, whether the lender needs to verify invoices with your customers before going live, and whether an existing lender must release its charge over your debts. Once the facility is running, funds against newly submitted invoices often arrive within a working day, subject to the funder's cut-off times and any same-day payment fee.
Moving from one factor to another adds time, because the outgoing funder's ledger has to be settled or bought out and its notice period served.
Factoring is secured mainly on the invoices themselves, which the funder buys or takes an assignment over, but most lenders also take further security. A typical package includes a debenture over the company, giving the funder a charge over its book debts and other assets. Our guide to debentures and fixed and floating charges explains how these rank.
Directors are commonly asked for a warranty or indemnity, which makes them personally liable if invoices turn out to be invalid, for example because the work was never done or the invoice was raised twice. Some lenders also ask for a personal guarantee. Read our guide to personal guarantees before signing, and ask what the funder will accept in place of an unlimited guarantee.
Factoring is usually priced with two main charges, a service fee and a discount charge, plus a number of smaller fees that vary by lender. Understanding each one matters more than comparing a single headline number.
The minimum fee catches many businesses out. If your turnover falls below what the facility was priced on, you may still pay the minimum. Ask any lender to show the total cost on your realistic turnover, not just the headline service fee.
Whole-turnover factoring agreements usually run for a minimum term, often 12 months, followed by a notice period, often three months. Leaving early can mean termination fees, and when you do exit you will need to repay the outstanding prepayments, either from collected debts, from a new funder or from your own cash. Check the notice period before you sign, not when you want to move.
Spot factoring funds a single invoice or a small batch of chosen invoices, without committing your whole sales ledger. It suits occasional cash needs, such as a large order or a seasonal peak, but the cost per invoice is usually higher and some funders only take invoices to customers with strong credit. We cover it in detail on our selective invoice finance page.
If factoring does not fit, the main alternatives are other forms of invoice finance, revolving facilities and term borrowing. Each solves a slightly different problem.
If the real issue is a few slow payers rather than a structural cash gap, our guide to chasing late payments may help first.
Factoring lenders assess your customers and your invoices first, and your business second. A strong debtor book can carry a younger company that a term lender would turn down.
The credit standing of the businesses that owe you money, their payment history and whether they are UK or overseas.
How much of your ledger sits with one customer. Most facilities carry a concentration limit, which caps the share of the funded book any single customer can represent. Debts above the cap may be funded at a lower rate or not at all. If one customer dominates your sales, a high-concentration facility may be the better route.
Whether an invoice represents completed work or delivered goods that the customer cannot reasonably dispute. Contra trading, where you also buy from a customer, and sale-or-return terms both reduce what lenders will fund.
The proportion of invoiced value lost to credit notes, discounts and disputes over time.
Your standard terms, payment periods and whether contracts restrict assignment of debts.
Filed accounts where available, tax position, existing borrowing and charges, and the directors' credit history.
Lenders usually ask for a current aged debtor report, an aged creditor report and a sample of recent invoices with proof of delivery. Beyond those, expect requests for:

The main advantage of factoring is fast, scalable cash combined with professional collections; the main drawback is that customers see a funder involved and you pay for that service.
| Advantages | Disadvantages |
|---|---|
| Releases most of an invoice's value soon after it is raised | Usually disclosed, so customers know you use a funder |
| Funding grows automatically with sales | Service fees are higher because collections are included |
| Credit control is handled by an experienced team | You give up some control over how customers are chased |
| Accessible to younger businesses with good customers | Minimum terms, notice periods and minimum fees reduce flexibility |
| Optional bad-debt protection on approved customers | Concentration limits can restrict funding on your largest accounts |
How the main business finance structures work. Lenders set their own terms, so treat this as a guide to the questions to ask.
| Option | How you repay | Security | Often used for |
|---|---|---|---|
| Unsecured business loan | Fixed instalments, usually monthly | No charge over assets; a personal guarantee is usually required | Growth, stock, tax bills and cash flow |
| Secured business loan | Fixed instalments, often over a longer term | A charge over property or other assets | Larger sums, property and refinancing |
| Revolving credit facility | Interest on what you draw; repay and redraw | Varies by lender and case | Recurring or uneven cash flow gaps |
| Merchant cash advance | A share of future card takings | No charge over assets | Card-taking businesses with uneven months |
| Asset finance | Regular payments over the life of the asset | The asset being financed | Equipment, vehicles and machinery |
| Invoice finance | Settled as customers pay their invoices | Your unpaid invoices | Businesses waiting on customer payment |
General information only. Every lender has its own criteria, and all finance is subject to status.
The key difference is who chases your customers: in factoring the funder runs your sales ledger, while in invoice discounting you keep your own credit control and the facility is usually confidential.
| Feature | Invoice factoring | Invoice discounting |
|---|---|---|
| Who runs credit control | The funder | Your business |
| Customers aware of the funder | Yes, usually disclosed | Usually not, often confidential |
| Typical cost level | Higher, as collections are included | Lower service fee |
| Eligibility | Open to younger and smaller businesses | Needs more turnover, a track record and good ledger controls |
| Lender monitoring | Built into the service | Regular reporting and periodic audits |
Many businesses start with factoring and move to discounting once their turnover and systems mature. Our guide to factoring vs invoice discounting sets out how to decide.
We start by looking at your debtor book, your customers and how you want collections handled, then approach lenders on our panel whose appetite fits your sector, size and concentration. We compare the service fee, discount charge, minimum fees, recourse terms, notice periods and security requirements side by side, so you can see the realistic cost on your actual turnover rather than a headline figure. Lenders make every credit decision, and we stay involved through the survey and set-up. It is free to enquire; any broker fee is disclosed separately before you proceed. To talk through your ledger, contact our team.
Illustrative figures from the numbers you enter, before you speak to a lender.
Yes. Because the facility is disclosed, the factor writes to your customers to confirm the new payment details and may call them to verify early invoices. You can usually agree the tone of collection calls and an escalation process in advance, and many funders brand their correspondence neutrally. Tell your key customers before the facility starts so the first contact is not a surprise.
Often, yes. Factoring is not limited to limited companies, provided you invoice other businesses on credit terms. Lenders may take different security from an unincorporated business because a debenture is a company instrument, so expect personal assignments or guarantees instead. The range of lenders can be narrower, which is where searching a wide panel helps.
A disputed invoice is normally made ineligible until the dispute is resolved. The funder may reduce your available funding by the prepayment it made against that invoice, or ask you to replace it with a fresh one. Disputes are rarely covered by bad-debt protection, which usually responds to insolvency rather than complaints about goods or services.
You can usually leave early, but the agreement will set out termination fees and the notice you must give. On exit you must settle the funder's outstanding prepayments and charges, after which it releases its security. If another funder is taking over, it typically buys out the existing ledger so collections continue without a gap.
On a whole-turnover facility the funder normally expects all trade debts to be assigned, although some agree to exclude named customers, such as an overseas account or a related company. If you only want to fund particular customers or invoices, a selective arrangement is usually the more honest fit than a whole-ledger contract with many exclusions.
