Bank Details on an Invoice: What to Include

Short answer

Put only the verified bank information the customer needs to make the payment. Depending on the country and transfer type, this may include the account name, bank name, account number or local routing details, IBAN, SWIFT/BIC, invoice currency, and the invoice number to use as the payment reference. Never include passwords, PINs, card details, or authentication codes.

Bank details commonly used

The required fields depend on the payment network and countries involved. A payment section may include:

• Account holder name.
• Bank name.
• Account number.
• Local routing, branch, sort, BSB, or transit code where applicable.
• IBAN for supported international and regional transfers.
• SWIFT or BIC for relevant international transfers.
• Invoice and payment currency.
• Invoice number or customer reference.
• Payment contact for questions.

Do not add every possible field. Provide the specific details needed for the accepted payment route.

Account name and business name

The account holder should have a clear, legitimate relationship to the supplier shown on the invoice. A brand and legal entity may use different names, but unexplained differences can delay payment or trigger fraud review.

Use what business name to put on an invoice to make the seller identity and trading name clear.

Make the currency explicit

State the invoice currency and the amount the customer should transfer. A dollar symbol alone may refer to several currencies.

If the payment currency differs from the invoice currency, agree on the conversion method, exchange-rate source and date, and responsibility for transfer fees. The multicurrency invoice guide explains the record requirements.

Use the invoice number as a reference

Ask the customer to include the unique invoice number in the transfer reference. This helps match incoming funds to the correct customer and balance.

For example:

• Invoice number: SB-1082.
• Amount due: NZD 1,250.
• Requested payment reference: SB-1082.
• Account name: Example Services Ltd.
• Account details: the verified local fields required by the bank.

The invoice payment reference number guide covers reference design and reconciliation.

Where should bank details appear?

Place payment instructions near the amount due or in a clearly labeled payment section. Keep them separate from supplier and customer addresses so readers do not mistake a bank address for the business address.

An invoice note can repeat the requested reference or payment contact, but critical payment information should not be hidden in a long paragraph. See invoice notes examples.

Bank detail change fraud

Unexpected changes to payment details are a common fraud risk. A criminal may imitate a supplier, alter an invoice, or compromise an email account and redirect payment.

Use controls such as:

• Verify changed details through a trusted contact and separate channel.
• Do not rely solely on the email that requested the change.
• Inform established customers before a legitimate change.
• Restrict who can edit invoice templates and payment settings.
• Check the exported PDF before sending.
• Preserve approval and change records.
• Encourage customers to verify unusual requests.

Do not publish full bank details on a public webpage or in an article when a protected invoice or payment portal is more appropriate.

Privacy and sensitive information

Bank details used to receive transfers are still financial information and should be handled carefully. Include only what the payer requires and send the invoice through an appropriate channel.

Never include:

• Online banking username or password.
• PIN or authentication code.
• Full payment-card number or security code.
• Identity-document scans.
• Security questions or recovery information.
• Unrelated account statements or balances.

Alternative payment methods

An invoice can also offer a secure payment link, card processor, direct debit, wallet, check, or another accepted method. Label any fees, currency, or restrictions clearly and follow the agreement.

The payment request vs invoice guide explains why a payment link supports but does not automatically replace the invoice.

After payment arrives

1. Confirm the payer, amount, currency, date, and transaction reference.
2. Match the transfer to the correct invoice.
3. Record partial, combined, short, or excess payments accurately.
4. Update the balance and status.
5. Send a payment confirmation or receipt when appropriate.
6. Retain the invoice and transaction evidence securely.

Use the invoice reconciliation process for a repeatable workflow.

Final checklist

• Account holder matches or clearly relates to the supplier.
• Bank and routing fields suit the payment method.
• Invoice and payment currency are explicit.
• Invoice number is requested as the reference.
• Payment instructions are easy to find.
• Changed details were independently verified.
• No passwords, PINs, card data, or authentication codes appear.
• Final PDF and payment destination were checked before sending.

FAQs

Are bank details required on every invoice?

No. Include them when bank transfer is an accepted method and the customer needs the information. A secure link or portal may be used instead.

Is it safe to put an account number on an invoice?

It may be necessary for receiving transfers, but handle the invoice as financial information, limit unnecessary fields, and use appropriate delivery and verification controls.

What reference should the customer use?

The unique invoice number is usually the clearest reference. Add a customer account or other reference only when the payment system or agreement requires it.

Should I email customers when bank details change?

Yes, but email alone may not be sufficient. Ask customers to verify the change through a known contact or trusted channel before making payment.
