Doing business with the City

If you are interested in doing business with the City, then you must read this section about how the City selects suppliers for goods and services.

  • All City officers and employees must observe the highest standards of ethics and integrity in any purchasing activity, and act in an honest and professional manner.

    The following principles, standards and behaviours must be observed and enforced through all stages of the purchasing process. This ensures the fair and equitable treatment of all parties.

    • Accept full accountability for all purchasing decisions and the efficient, effective and proper use of public monies based on achieving value for money
    • Purchasing practices must comply with relevant legislation, regulations, and requirements consistent with City policies and the code of conduct
    • Purchasing is made on a competitive basis where all potential suppliers are treated impartially, honestly and consistently
    • All processes, evaluations and decisions are transparent, free from bias and fully documented in accordance with applicable policies and audit requirements
    • Any actual or perceived conflicts of interest are identified, disclosed and appropriately managed
    • Any information given to the City by a supplier is treated as commercial-in-confidence and is not to be released unless authorised by the supplier or relevant legislation.
  • Value for money is an overarching principle governing purchasing that allows the best possible outcome for the City. This is more important than achieving the lowest price, and should take into account:

    • User requirements
    • Quality standards
    • Sustainability
    • Life cycle costing
    • Service benchmarks.
  • The City of Stirling implemented Open Windows as its Contract Management System on the 28 January 2020. Any Supplier under a current contract or engaging in a new contract will need to register through Open Windows. To go to the registration page please click here.

    All communications associated with a Contract will be channelled through the Open Windows platform with the exception of tenders and invoices which will continue through the current used options. This is a large change for the City and its valued Suppliers so it is expected that this transition will take time and continuous open communication between all parties will be necessary.

    There are a number of benefits associated with the Open Windows platform as a registered Supplier and these include:

    • Trackability of communications between the City and your Business no matter how many people are involved in those communication
    • Easy access to a list of all your contracts for customers using Open Windows (not just City of Stirling's contracts but other businesses across Australia using Open Windows)
    • Submission of contract related documents only once to reduce duplication and wasted time in the Contract Management process, e.g. Insurances. Certain contract specific documents will still need to be lodged for each contract but this will be for documents like Registrations and Licenses
    • A consistent framework for dealing with contract items with the City
    • Alerts provided via the Supplier Portal when certain contract documents are due to expire
    • Access to a larger customer base as Open Windows is used by many businesses across Australia and ability to see Tenders that are processed through the Open Windows platform
    • Full support will be provided by Open Windows when you use the platform (support hours are based on Eastern States Business hours).

    To find out more information, visit the Open Windows website here.
