Westpac Invoice Finance: Broker Guide

Westpac invoice finance advances funds against unpaid business invoices, with availability changing as invoices and customer payments move through the ledger. Westpac currently accepts enquiries for Invoice Finance through its specialist team and business-broker channel, as at October 2026.

The broker’s first decision is whether the client meets the applicable entry criteria. The next is whether the receivables support the cash the client needs, after exclusions and debtor limits.

Verify the Current Westpac Product

Westpac’s current product is Invoice Finance, issued by Westpac Banking Corporation, as at October 2026. Its Invoice Finance details has a new-business enquiry route alongside a separate existing-facility sign-in.

The current public offer targets business-to-business operations with multiple customers. It lists minimum annual turnover of $4 million and funding limits from $1 million. Westpac’s business-broker product page instead lists $2.5 million turnover and limits from $500,000.

Treat those as conflicting channel descriptions, not permission to promise the lower thresholds. For a client between the two sets, send the commercial team the turnover and requested limit for a written channel-specific decision.

An existing-customer login establishes a servicing route. Use the current enquiry or commercial contact route to start a new proposal. Keep old brochures and saved eligibility summaries separate from the terms offered for this client.

Test the Client’s Receivables

Build the potentially eligible ledger invoice by invoice before estimating Westpac funding. As at October 2026, Westpac’s cash-flow page describes advances of up to 85% of approved unpaid invoices and ongoing limits from $1 million.

Start with a dated aged-receivables report. Add a working column for each assessment issue below, so the specialist can decide what qualifies.

Assessment issue	What to show in the proposal
Invoice type	Separate completed goods or services from deposits, progress claims, retentions and related-party invoices.
Debtor location	Identify domestic and overseas debtors, invoice currency and the contracting customer entity.
Ageing	Show invoice date, due date and days overdue. Separate long-outstanding balances.
Disputes	Flag rejected deliveries, disputed work and amounts subject to customer approval.
Dilution	Record credit notes, returns, rebates and offsets that reduce the amount collected.
Concentration	Show each major debtor’s share of the ledger and any common ownership between debtors.

These are assessment categories for your proposal, not automatic Westpac exclusions. Put an unusual invoice class into its own subtotal for the credit decision.

A Provisional Ledger Calculation

In this hypothetical example, a client with $6 million annual turnover requests a $1 million facility. Its unpaid ledger totals $1.5 million.

The broker sets aside $150,000 of disputed invoices and $100,000 of pending credit notes for assessment.

That leaves $1.25 million potentially eligible. At the advertised 85% ceiling, the provisional advance is $1,062,500. An approved $1 million facility would cap borrowing at $1 million before any further reserves or adjustments.

If a debtor-limit adjustment removed another $200,000 from that provisional ledger, 85% of the remaining $1.05 million would be $892,500. That would leave a $107,500 gap against the requested cash.

Those exclusions and the debtor adjustment are illustrative assumptions, not Westpac policy figures. Subtract existing advances and any applicable reserves when calculating additional cash available. An approved limit and an undrawn cash balance are different amounts.

Use the invoice-finance assessment guide for the wider suitability assessment. Keep the Westpac proposal focused on the client’s ledger and this facility’s terms.

Map Control and Recourse Terms

Westpac keeps Invoice Finance confidential while the client manages collections, as at October 2026. Invoice receipts go into a dedicated Westpac collection account with view-only client access.

Overnight transfers reduce advances. Drawdowns go into a separate transaction account.

Late or unpaid invoices reduce available funding. Westpac explains that future invoices and other customers’ payments cover a shortfall. Treat that as continued exposure to bad debts, not a promise of credit insurance.

Before acceptance, map the facility agreement to the client’s daily processes. Record who maintains invoice data, how Westpac verifies invoices and when debtor limits or reserves change. Establish what happens if availability falls below advances already drawn.

The advertised advance ceiling leaves part of the ledger unadvanced. Distinguish that portion from any separate reserve imposed by the facility terms. Show both in the availability calculation.

Westpac’s public offer requires no real-estate security. The invoices secure advances. Read the proposed security and guarantee clauses together before describing the client’s wider liability.

Westpac identifies interest, an establishment fee and a line fee. Compare the written quote using expected drawings and the approved limit, including any minimum or exit charges it specifies. Avoid pricing the proposal as interest alone.

The client must accept controlled receipts, ongoing ledger reporting and active debt collection. A business that needs unrestricted access to every customer payment must resolve that operating requirement before proceeding.

Prepare Westpac Evidence

Prepare a reconciled receivables file for Westpac’s specialist, with supporting business records ready for the application. As at October 2026, Westpac’s product route moves from specialist enquiry to an online application, document upload, quote and facility agreements.

Use the following preparation pack to explain the proposal. It is a broker checklist for assessment, not a claim that every item is mandatory for every application.

• A dated aged ledger with customer-level balances and credit notes.
• Debtor contracts and payment terms, including retention, offset or assignment clauses.
• Representative invoices with delivery records, work acceptance or other transaction evidence.
• Current financial accounts and recent management figures supporting turnover and the funding need.
• Business bank statements showing receipt patterns and existing facility conduct.
• Tax records and details of arrears or payment arrangements.
• A schedule of existing finance and security, with the proposed treatment of any receivables facility being replaced.

Reconcile the ledger total to the accounts and explain timing differences. Trace sample customer payments from invoice to bank receipt. Show the peak working-capital need separately from the amount presently outstanding.

Give every exception a value and a document reference. A disputed $80,000 balance needs its correspondence and expected resolution, not a general comment that collections are improving.

Westpac’s general business-broker page has consent resources and a broader submission checklist. Its Business Loan and Business Overdraft form instructions name those products. Obtain the invoice-finance specialist’s application instructions for this facility before lodging the pack.

Submit and Escalate the Scenario

Use Westpac’s business-broker accreditation route and commercial contacts for broker access, as at October 2026. The accreditation page directs aggregator-affiliated brokers to their aggregator first, including checking the relevant Westpac panel access.

The business-broker process requires an application, aggregator sign-off and lodgement of supporting documents. Successful applicants receive business-finance accreditation and a business development manager (BDM) contact. Use that business-finance contact to route the invoice proposal.

For a direct new-business enquiry, the Invoice Finance enquiry form requests business and contact details. Westpac states that a specialist will respond within one to two business days. Brokers can also use Westpac’s commercial contact directory.

Send one concise scenario request before promising eligibility or drawing capacity. For the hypothetical client above, a useful request reads as follows.

The client has $6 million annual turnover and needs a $1 million Invoice Finance facility. The unpaid ledger is $1.5 million. Disputes total $150,000 and pending credit notes total $100,000. The largest debtor owes $500,000. Please assess the invoice classes and debtor locations in the attached ledger. Confirm eligible balances, debtor limits, reserves and the advance basis. Please provide pricing. Set out security and guarantee terms, plus the application route for this broker accreditation.

Retain the written response with the reconciled ledger. Before the client accepts, match the approved borrowing base and controlled-receipts process to the forecast cash requirement. If Westpac’s entry criteria or receivables treatment leave a funding gap, use the invoice-finance provider guide to assess another receivables-funding route.
