Quick answer
What does invoice finance release?
Invoice finance can release an agreed part of eligible unpaid business invoices before the customer pays. The important word is eligible: overdue, disputed or concentrated debts may be treated differently. Compare the available advance, all charges, customer contact arrangements and responsibility if a customer fails to pay.
Key points
- The sales ledger matters as much as headline turnover.
- An advance percentage applies to eligible debt, not necessarily every invoice.
- Factoring and discounting involve different collection arrangements.
- Ask what happens to availability when a customer pays late or disputes an invoice.
Where is the cash gap in your sales cycle?
Start with the journey from doing the work to receiving the cash. A company might pay labour every Friday, buy materials before delivery and allow its business customer 45 days to settle. The order may be profitable while still creating a difficult gap in the bank balance. A ledger-based facility is one category to investigate when that timing pattern repeats.
Write down when invoices are issued, their normal payment terms and the dates customers actually pay. Separate a slow but reliable payer from a genuine dispute. If the main problem is that invoices have not yet been approved or work has not reached the billing milestone, the face value of the order does not establish what can be financed.
How do factoring and invoice discounting differ?
In factoring, the provider typically takes a role in ledger administration and collections. Invoice discounting generally leaves more of that activity with the business. The British Business Bank’s invoice finance guide describes both arrangements and explains that the unpaid invoices support the advance [1]. Confidentiality and practical processes still depend on the actual facility.
Before choosing, consider who already handles credit control and what customers will see. Ask how a disputed invoice is managed, which bank details appear on invoices and who answers a customer’s allocation query. Outsourcing collection work changes a real customer process; it deserves more attention than a line in a fee comparison.
Which invoices enter the available balance?
Ask the provider to explain its eligible-debt calculation using your own anonymised ledger. The starting sales-ledger total may be reduced for invoices outside the permitted age, disputes, certain customer locations or limits on exposure to one customer. Those adjustments can matter more to usable cash than a small difference in the advertised advance percentage.
Take the largest customer as a separate scenario. If a substantial part of the ledger depends on that customer, ask what happens when its balance reaches a concentration limit or a payment is late. A facility limit is a ceiling; it is not a guarantee that you can draw the full amount whenever you choose.
| Ledger detail | Question to resolve |
|---|---|
| Invoice dates and due dates | Which ageing limits apply? |
| Customer concentration | Is availability capped for one debtor? |
| Disputes or credit notes | When is the invoice removed or reduced? |
| Overseas or connected customers | Are these debts included? |
| Existing receivables finance | Who already has rights over the debt? |
A simple advance example
Assume, purely for illustration, that £50,000 of invoices meets a facility’s eligibility rules and the agreed advance is 80%. The initial available amount would be £40,000. If the invoices are paid in full and total charges attributable to them are £1,000, the remaining release would be £9,000: £50,000 less £40,000 already advanced and £1,000 of charges.
Now suppose £10,000 of the ledger is ineligible. At the same assumed advance percentage, the available initial funding falls to £32,000. This example is arithmetic, not a quoted advance or cost. It shows why the eligibility calculation and the timing of deductions belong beside the percentage on your comparison.
Which charges should you put together?
Request a complete schedule covering the service fee, the charge for money drawn, minimum charges and any setup, audit, transaction or termination costs that apply. Establish the base used for each percentage: all turnover, assigned turnover, invoice face value or the amount drawn. Two identical-looking percentages can apply to different numbers.
Build two cost scenarios from the same ledger: normal payment timing and slower collection. Ask the provider to calculate both. Also model a quiet month when a minimum fee could remain even though funded sales are lower. The aim is a cash figure tied to the way your business trades, rather than a comparison of percentages with different definitions.
What happens if the customer does not pay?
Ask when you must repay an advance or replace an invoice if the customer is late, insolvent or disputes the work. Do not assume that funding an invoice transfers every non-payment risk. If bad-debt protection is offered, request its own scope, exclusions and claim conditions [1]. A dispute about delivery may not be treated like a qualifying insolvency.
Keep proof of delivery, acceptance records, purchase orders and credit notes organised. A healthy ledger is easier to explain when the company can show why each balance is due. If a customer has already challenged the invoice, tell the provider; hiding the dispute does not make the cash dependable.
How would the facility work with your team?
Map a week of administration before signing: who uploads invoices, reconciles receipts, notifies credit notes and checks the borrowing balance? Ask whether the provider connects to your accounting system and which actions still need a person. A demonstration using sample data can reveal practical work that a feature list misses.
Plan the customer communication too. Confirm the verified payment details, how a new collection arrangement is announced and how customers can check a change safely. Agree an internal owner for discrepancies so that a finance facility does not become an extra set of unanswered allocation queries.
What should you prepare for an initial conversation?
Prepare an aged-debtor summary, a list of major customer balances, normal terms, recent turnover and an explanation of the funding gap. Add existing finance agreements and any rights already granted over invoices. Start with a summary; agree a secure route before sharing a detailed ledger containing customer information.
Invoice finance is most useful to investigate when the question is about cash held in qualifying receivables. If the company is buying equipment or financing work long before it can invoice, another category may need to sit alongside it. Felix helps describe the requirement; provider assessment establishes what, if anything, can be offered.
Frequently asked questions
Straight answers
Will every unpaid invoice count?
No. The provider applies its own eligibility and concentration rules. Ask for the calculation against your actual ledger.
Will customers know?
That depends on the collection and disclosure arrangement. Factoring commonly involves provider contact; do not assume that every discounting agreement is confidential.
Does the advance remove bad-debt risk?
Not automatically. Ask about recourse, repayment triggers and any separately offered protection.
Can a smaller business explore it?
Criteria differ. A provider may offer a whole-ledger or selective arrangement, but Felix does not promise access based on company size.
Is the facility limit cash I can always draw?
No. Drawings also depend on eligible debt, existing advances and the facility’s conditions.
