Invoice finance or cash flow loans: which is best for my business?

Summary: If unpaid invoices are constraining growth, invoice finance (factoring or invoice discounting) will often release working capital fastest and fit businesses with repeat B2B invoices. If you need a fixed lump sum for a one‑off cost (seasonal stock, supplier payment or short-term bridge) a cash flow / working capital loan may be better. Not sure which suits you?

Quick answer — TL;DR

If your main problem is cash tied up in unpaid B2B invoices, invoice finance (factoring or invoice discounting) usually releases funds fastest and scales with your sales. If you need a fixed lump sum for a short-term need (seasonal stock, an urgent supplier invoice, one-off project costs), a cash flow / working capital loan may be more suitable. If you’re unsure, complete a short enquiry and we’ll match you to lenders and brokers who can provide quotes for loans from around £10,000 upwards. Free Eligibility Check

How this page helps you

Read on to understand the practical differences, typical costs, who each option suits (construction, manufacturing, distribution, recruitment, etc.), and a short decision checklist to help you pick the right solution — plus how UK Business Loans can match you to appropriate lenders and brokers.

What is invoice finance?

Invoice finance (also called invoice financing) is a way to unlock cash tied up in unpaid B2B invoices. Instead of waiting 30–120 days for customers to pay, a specialist provider advances most of the invoice value so you can use the money immediately. Invoice finance usually comes in two main forms:

• Invoice factoring — the finance company buys or advances against your invoices and typically handles credit control and collections. Customers may be notified that invoices are being assigned.
• Invoice discounting — you retain control of collections and the arrangement is usually confidential (customers are unaware). This suits businesses that want to preserve customer relationships and privacy.
• Other options include select/spot factoring — finance on individual invoices rather than a whole ledger.

Typical advance rates range from about 70% to 90% of invoice value, depending on debtor credit quality. Fees include a finance (discount) fee (often charged monthly as a percentage of advanced amount) and an administration/service fee. Invoice facilities can be ongoing lines that scale with sales or one-off deals for specific invoices. Many providers can make an initial advance within 24–72 hours after checking documents and agreeing terms.

What are cash flow / working capital loans?

Cash flow or working capital loans are short- to medium-term loans designed to cover a funding gap. They come in several forms: unsecured business loans, short-term bridging loans, revolving credit facilities, or overdrafts provided by banks and specialist lenders. Typical uses are one-off supplier payments, seasonal stock, temporary payroll or short project bridging.

• Structure: usually a fixed sum with interest charged over an agreed term; some lenders offer revolving lines where you borrow and repay repeatedly.
• Costs: interest (daily/monthly), arrangement fees and sometimes early repayment penalties.
• Speed & eligibility: some specialist lenders can fund quickly, but decisions depend on credit profile, trading history, and security requested (unsecured options may be available, but rates will reflect risk).

Side‑by‑side comparison: invoice finance vs cash flow loans

Feature	Invoice finance	Cash flow / working capital loan
Best use-case	Free up cash from unpaid B2B invoices; ongoing working capital	One‑off lump sum or short-term bridge; seasonal funding
Speed to funds	Often 24–72 hours after facility agreed	Typically hours to a few days (depends on lender)
Costs & fees	Advance fee/discount (e.g., 0.5–3% per month), service fees	Interest + arrangement fees; APR varies
Eligibility	Requires strong B2B invoice book and trading history	Focus on company credit, turnover, sometimes director covenants
Security & covenants	Facility against invoices; may require assignment/reserve	May be unsecured or require assets/personal guarantees
Customer impact	Factoring can notify customers; discounting can be confidential	No impact on customers
Scalability	Scales directly with sales and invoice volumes	Fixed sum unless you refinance or take further borrowing

Which businesses often choose this? Invoice finance: B2B distributors, manufacturers, recruitment agencies, logistics and construction firms with large debtor days. Cash flow loans: retailers buying seasonal stock, firms needing a one-off supplier payment, or businesses with temporary shortfalls.

Example calculation — On a £100,000 invoice with an 85% advance and a 1% discount fee: advance = £85,000; discount fee (1% of £100,000) = £1,000; net cash on day one commonly ≈ £84,000 (less any reserve). This helps visualise the immediate cash available versus waiting for customer payment.

Which is best for your business? Practical decision guide

Answer these questions to guide your choice:

• Is unpaid invoice credit the main cause of your cash shortage?
• Do you invoice other VAT‑registered UK limited companies with predictable payment patterns?
• Do you need confidentiality around finance arrangements?
• Is the need one‑off (single purchase) or ongoing?
• How quickly do you need access to cash?
• What’s your company’s credit score and trading history?

Short recommendations by scenario:

• If unpaid invoices are the problem: Likely best — Invoice finance (factoring or discounting).
• If you need a one-off lump sum quickly: Likely best — Cash flow / working capital loan.
• Construction subcontractor waiting on retentions / long payment terms: Invoice finance often preferred.
• Retailer buying Christmas stock: Short-term loan or seasonal facility may be better.
• If your credit profile is imperfect but you have strong debtors: Invoice finance can be more accessible as underwriters look at debtor quality.

Costs, fees and what to look for

Typical fees to expect:

• Advance/discount fee: often 0.5–3% per month on the invoice value (varies by debtor risk and provider).
• Interest on loans: depends on lender and security; compare quoted APRs and effective monthly cost.
• Setup / facility fees: one-off costs to open a facility.
• Service & admin charges: monthly account fees, audits, credit control charges.
• Hidden elements to check: reserve accounts, minimum monthly fees, early repayment penalties, collection/credit insurance costs.

Always ask providers for a written illustration showing effective cost over your expected usage period so you can compare like‑for‑like.

Eligibility & speed: what lenders check

Invoice finance providers focus on the quality of your debtor book: customer creditworthiness, concentration risk (too much owed by one buyer), average debtor days, and trading history (typically at least 6–12 months). Cash flow lenders focus more on company accounts, turnover, profitability and director credit scores. Using UK Business Loans speeds the process: tell us your needs and we match you to lenders/brokers who specialise in your sector and profile — often producing quotes within hours.

Risks and how to manage them

• Operational: factoring may affect customer relationships if disclosed — choose discounting if confidentiality is critical.
• Financial: ongoing invoice finance can become expensive if used long-term; compare to loan APRs.
• Contractual: watch minimum terms, termination fees and reserves; get full terms in writing.

Tips: request a full cost schedule, ask for worked examples, and compare multiple offers before proceeding.

Short case studies

1) B2B distributor (problem) — Waiting 60–90 days for large customer payments left the firm unable to buy seasonal stock. Solution: invoice discounting facility secured; advanced 85% of invoice value; new stock purchased and sales increased 15% that quarter.

2) Subcontractor in construction (problem) — Cash shortfall from retentions and slow pay meant missing a bid for a new contract. Solution: selective factoring for certain clients plus short-term working capital loan to bridge immediate cashflow; contract won and workload kept stable.
