Documents Needed for Invoice Finance
You need 12 months of business bank statements, latest management or filed accounts, an aged debtor list, 3 sample invoices with proof of delivery, and director ID (passport or driving licence). Having these ready before you apply can cut setup time from 2 weeks to under a week. More detail + scope
Summary
The document requirements for invoice finance are simpler than most business lending. The provider's primary concern is the quality of your debtors (customers), not your own credit history. Bank statements show cash flow patterns, the aged debtor list shows who owes you money and whether they pay on time, and sample invoices confirm your invoicing practices are clean and fundable.

Having your documents ready before you apply is the single biggest thing you can do to speed up the process. Providers chasing missing paperwork is the number one cause of delays. Here is every document you might need, grouped by category, with clear guidance on which are essential and which are optional.
Company Documents
These confirm your business is legitimate and properly registered. Most providers will verify details via Companies House, but having copies ready shows you are organised.
| Document | Essential? | Notes |
|---|---|---|
| Certificate of incorporation | Yes | Download from Companies House if you cannot find the original |
| Articles of association | Sometimes | Required if your articles have been amended from standard model articles |
| Shareholder details | Yes | Confirmation statement or share register showing all shareholders with 25%+ ownership |
| VAT certificate | If VAT registered | Confirms your VAT number is active and matches your invoices |
| Proof of business address | Sometimes | Utility bill or business rates bill for your trading address if different from registered address |
Financial Documents
These are the most important documents in your application. The provider uses them to assess your financial health and the quality of your debtor book.
| Document | Essential? | Notes |
|---|---|---|
| 12 months business bank statements | Yes | The single most important document. Shows cash flow, payment patterns, and whether you have bounced payments or returned direct debits |
| Latest management accounts | Yes | P&L and balance sheet for the current year to date. Does not need to be audited. Your bookkeeper can prepare these |
| Latest filed accounts | Yes | Your most recent accounts filed at Companies House. If micro-entity accounts with limited detail, also provide the full management accounts |
| Aged debtor list | Yes | Export from your accounting software (Xero: Aged Receivables report, Sage: Aged Debtors). Shows who owes you money and how overdue |
| Aged creditor list | Sometimes | Shows who you owe money to. Providers use this to check for HMRC arrears and to understand your overall financial position |
| Cash flow forecast | Optional | Helpful for startups or businesses applying during a loss-making period. Shows the provider how the facility will improve cash flow |
Invoice Samples and Proof of Delivery
Providers need to see your actual invoices to confirm they are fundable. A "fundable" invoice must be for goods or services already delivered, addressed to a creditworthy business customer, with clear payment terms.
| Document | Essential? | Notes |
|---|---|---|
| 3 recent invoices | Yes | From different customers if possible. Must show your company name, customer name, description of goods/services, payment terms, and total amount |
| Proof of delivery or completion | Yes | Signed delivery notes, proof of completion, timesheets (for recruitment), or customer purchase orders. This confirms the debt is genuine |
| Customer contracts or purchase orders | Sometimes | Required for contract-based businesses (recruitment, construction). Shows the terms you trade on and confirms the customer relationship |
Identity and Verification
Anti-money laundering regulations require providers to verify the identity of all directors and any shareholders with 25% or more ownership (known as Persons with Significant Control).
| Document | Essential? | Notes |
|---|---|---|
| Director ID (passport or driving licence) | Yes | For all directors. Must be current and not expired. Colour scan or photo is usually acceptable |
| Proof of home address | Yes | Utility bill or bank statement dated within the last 3 months. Must match the address on the application |
| PSC (Person of Significant Control) ID | If different from directors | Any shareholder with 25%+ ownership who is not a director will need to provide ID and proof of address |
Tips to Get Your Documents Right
- 1.Download bank statements from online banking. PDF downloads from your bank's app or website are preferred over scanned paper statements. They are clearer, harder to alter, and some providers can run them through automated analysis tools.
- 2.Export your aged debtor list today, not last month. The provider wants the current position. A 3-week-old report will prompt questions about what has changed since.
- 3.Clean up overdue invoices before you apply. If your aged debtor list shows 20% of your debts are over 90 days old, that is a red flag. Chase overdue payments or write off bad debts before submitting your application.
- 4.Ensure invoices match your accounting records. Discrepancies between your aged debtor list, bank statements, and sample invoices will trigger additional investigation and slow everything down.
- 5.Prepare a one-page business summary. This is optional but impressive. A brief document explaining what your business does, who your main customers are, why you need the facility, and what you will use it for. It shows the underwriter you are serious and organised.
What If You Are Missing Documents?
Common situations and how to handle them:
- Startup with no filed accounts - Provide management accounts, a cash flow forecast, and any contracts or confirmed orders you have. Target startup-friendly providers like those that accept day-one trading.
- Less than 12 months of bank statements - Provide whatever you have. If your business bank account is new, also provide the personal bank account statements showing initial trading.
- No formal proof of delivery - Emails from customers confirming receipt, signed timesheets, or customer portal screenshots can work. Discuss alternatives with the provider before applying.
- Director living overseas - Notarised copies of ID may be needed. Some providers can do electronic ID verification for overseas directors.
