NAB Invoice Finance: Broker Guide

National Australia Bank (NAB) invoice finance releases cash from eligible unpaid business invoices through NAB Invoice and Debtor Finance. NAB advertises funding of up to 85%, with the available amount determined by the approved facility and ledger controls. For a broker, the first assessment is whether the business can support both the borrowing and the ongoing receivables reporting.

Establish NAB’s Current Product Position

NAB markets Invoice and Debtor Finance for new enquiries as at October 2026, issued by National Australia Bank Limited. Its current product page directs enquiries to business bankers and Trade and Working Capital specialists. This is a live product enquiry route, not an archived offer.

For a new scenario, contact the Trade and Working Capital Hub on 1300 224 029. Give the business’s turnover, trading history, debtor profile and requested funding purpose. Ask the specialist to identify the broker submission route for that facility before sending client records.

NAB’s 2025 commercial broker report describes brokers working with its specialist banking team on working capital solutions. A broker relationship does not itself establish which application channel or remuneration terms apply to this client.

Existing customers manage the facility through NAB Connect. Use the assigned account or relationship manager for an existing limit, access problem or proposed variation. Keep the facility agreement and subsequent written variations together when assessing an established customer’s terms.

Screen the Ledger for NAB

Screen the business first, then separate its gross receivables from the invoices available for funding. As at October 2026, NAB’s product page identifies businesses with turnover above $1 million and at least 12 months’ trading. It describes Australian business debtors paying in Australian dollars, payment terms up to 120 days and strong receivables processes.

These suitability indicators do not make every invoice eligible. Start with an invoice-level export, then prepare the following checks for the NAB specialist.

Ledger check	Evidence to include	Question the evidence resolves
Invoice completion	Tax invoice and delivery or completed-service evidence	Has the invoiced work actually been completed?
Debtor type	Legal customer name, location and contractual payment terms	Does the debtor fit the proposed facility?
Ageing	Invoice date, due date, unpaid balance and recent receipts	Which balances remain unpaid and for how long?
Concentration	Totals and percentage of the ledger for each debtor	Does one customer dominate the available security?
Adjustments	Credit notes, returns and write-offs matched to invoices	Is the outstanding amount overstated?
Disputes	Disputed amount, reason and supporting correspondence	How much depends on resolving a customer disagreement?

NAB’s July 2021 client guide, linked from its current help page, explains borrowing-base deductions. Credit notes reduce the ledger, while debtor limits and concentration controls can remove amounts from funding. The borrowing base is the receivables value supporting funds available under the facility.

The guide also removes invoices after the applicable recourse period and holds a retention until funded invoices are paid. Recourse here means an overdue invoice stops supporting funding. Use the client’s approved settings for ageing and concentration instead of treating the guide’s illustrative settings as current universal limits.

Keep invoice numbers and goods and services tax (GST) treatment in the export. Match credit notes to their original invoices and explain differences between the aged ledger and the financial accounts. For the broader assessment method, use the invoice finance guide.

Resolve Facility Operations

NAB’s confidential facility leaves the business responsible for collections and debtor relationships, as at October 2026. Receipts reduce the amount owing, while fresh eligible invoices support further funding. Decide who will collect debts and maintain the ledger before proposing the facility.

The July 2021 client guide describes these operating requirements. NAB can hold a pending invoice until it approves the invoice and evidence of completed delivery. Monthly reconciliation requires a Certificate of Debtors and the debtor ledger.

Have the NAB specialist put the proposed operating settings in writing. Cover debtor notification or verification rights, the collection account, recourse triggers and the reserve retained from invoices. Include reporting deadlines, review frequency and the action required if an invoice becomes disputed.

A business with suitable invoices can still be a poor operational fit if nobody can reconcile customer receipts or supply completion evidence. In that case, correct the process before relying on the facility to fund payroll or supplier payments.

Separate the Funding Amount From the Cost

NAB charges an application fee, a facility fee and a purchase charge. The facility fee uses the outstanding balance, while the purchase charge relates to purchased invoices or the facility limit. These are distinct cost components.

NAB’s indicator-rate schedule is not the customer’s complete quote. Request the applicable margin and each charge’s calculation basis, including tax treatment. Model the cost using expected drawings and invoice turnover, not just the headline limit.

Assemble the NAB File

Build the NAB file around financial capacity, invoice quality and the requested working capital need. As at October 2026, NAB’s general business-loan guidance identifies financial statements, tax returns, bank statements and a business plan as possible application evidence. Those are general preparation documents, not a fixed invoice-finance checklist.

Prepare this pack for the specialist’s assessment.

• Business financials and current management accounts, with turnover matched to the proposed borrower.
• Bank statements showing trading receipts and payment conduct, with existing borrowing identified.
• Tax returns and current tax balances, with any repayment arrangements explained.
• An aged receivables ledger and invoice export, reconciled to the accounts.
• Sample invoices and completion evidence, with debtor contracts showing payment terms or deductions.
• A funding-purpose explanation and cash flow forecast showing when cash is needed and how customer receipts replenish it.

Separate that evidence from the scenario decisions requiring NAB’s written response. Record the accepted debtors, advance rate, concentration caps and ageing rules alongside the proposed limit. Add security and guarantee requirements, the reporting timetable and the broker’s submission channel.

For a hypothetical transport business, one customer owing most of the ledger needs its own debtor analysis. Delivery records support completed jobs, while credit notes reduce what that customer owes. Send the specialist both the gross ledger and the adjusted breakdown so the requested limit has an identifiable basis.

Before submitting, each funding assumption must match either the client’s records or NAB’s proposed terms. If the resulting funding does not cover the business’s cash gap, use the invoice finance provider guide to assess another provider.
