Our suppliers assist us to deliver our vision and work towards building great outcomes for our customers.

We value and promote diversity in our supply arrangements.

Working together

For almost 160 years, we’ve been helping our customers with their money. However, we don’t do this on our own. We rely on partnering with suppliers to provide the best solutions. We have an extensive range of suppliers who work with us to deliver high quality products and services to our customers.

Our suppliers must share our strategic ambition, meet our business requirements and be appropriately screened to ensure that their arrangements and their supply pose minimal or no risk to our customers or us.

We encourage our suppliers to continuously improve their products and standard of service, to enhance our customer experiences and outcomes.

We monitor our supply arrangements to ensure that our standards are being met, including in contract performance, service delivery, risk management, and communication. We’re driving social impact through community grants, volunteering, workplace giving and supporting Indigenous success to help create stronger communities.

Sustainability supply chain

The conduct and performance of our suppliers can have a significant impact on our sustainability as a business, as well as our reputation within the communities we operate in.

We’re committed to making sure the practices of all the businesses within our Group are fair, responsible and sensitive to the needs of our stakeholders.

We encourage all our suppliers to become signatories to the NAB Group’s Supplier Sustainability Principles (PDF, 8.1MB) which specify the sustainability requirements for suppliers providing goods and services to our businesses.

We have risk management processes to identify, assess, mitigate and monitor potential risk areas where we could be exposed to human rights concerns, including modern slavery. These processes and actions we take each year are outlined in our Modern Slavery Statement.

More information about our sustainability progress, and how our suppliers help us deliver this can be found in our annual reporting suite.

Supplier diversity

Including diverse suppliers (businesses owned by women, Indigenous people, people with disabilities, and social enterprises) into our supply chain helps increase their exposure to corporate sourcing, while creating employment and training opportunities, sustainable growth and social and financial inclusion.

An internal working group implements our Supplier Diversity Program with representatives from Enterprise Sustainability, Strategic Sourcing and Social Impact. The working group aims to drive diversity in our supply chain directly and by facilitating introductions with our national tier one suppliers.


We’ve partnered with SAP Ariba, a global leader in the procurement solutions, to help streamline the way we work with our suppliers. They provide us with a source to pay platform that deliver benefits to our suppliers, which includes invoice automation, online catalogues and a secure site for your contact and banking details.

What does this mean for suppliers? We’ll be using SAP Ariba for sourcing goods and services, contract management and payments. If you’re not already on our SAP Ariba system, we’ll invite you to register. You can view more information about registering in the NAB Ariba Network Supplier Registration Pack (PDF, 2.50MB).

We’re also using SAP Ariba to invite suppliers to participate in sourcing events – e.g. request for information (RFI), request for proposal (RFP), request for quote (RFQ) – process agreement renewals, and amendments or change orders.

The NAB Ariba Network RFx Response Guide (PDF, 946KB) provides step by step instructions on how you as a supplier can respond to an RFx (RFI, RFP, RFQ) in the Ariba Network.

Small business payment terms

In 2017, we became a signatory to the Australian Supplier Payment Code developed by the Business Council of Australia. This provides small business suppliers with a standard payment terms of 30 days (however we intend to pay within 20 days to help support our small business suppliers) from receipt of a valid tax invoice. If you’re a small business and have any queries about this, please email our team.

Our preferred method of transacting is electronically via our procurement platform. We’ve made it even easier for our suppliers to use Ariba by paying for your registration for use of the Ariba system, and there are options available to suppliers.

Ariba Enterprise Enablement Account

The Enterprise Enablement Account is recommended for our key suppliers who have medium to high volume purchase order (PO) and invoice transactions (i.e. total is greater than 100 per annum). Suppliers holding Enterprise Enablement Accounts receive full SAP Ariba onboarding support and continued support throughout the transacting journey. We’ve chosen to cover Ariba Network Enterprise account fees on behalf of specific customer relationships. This will allow suppliers to use Ariba Network in connection with National Australia Bank Limited at no cost. That said, there may be fees if suppliers opt for extra services, or transact with buying organisations other than NAB on the Ariba Network.

Ariba Standard Account

The Standard Account is recommended for suppliers who generally have low volume transactions (less than 100 PO’s and invoices per annum). This is a customer driven onboarding process and whilst SAP Ariba don’t offer onboarding services to support this account, we’ll provide a welcome to transacting guide to help onboard suppliers. Suppliers are not subject to any SAP Ariba transactions fees and have the flexibility to upgrade to an Enterprise Enablement account if needed.
