What is a expression of interest?

An expression of interest, or EOI, is a document an applicant submits to register genuine interest in an opportunity such as a tender, project, grant or shortlist. It typically sets out who the applicant is, relevant capability or experience, and confirmation that they wish to be considered, without committing to the full detail of a formal bid. It is often the first stage of a two-step procurement or selection process.

EOIs matter because they let the party running the process filter and shortlist before inviting detailed proposals, saving time for everyone. A signed EOI confirms the applicant's intent and that an authorised person stands behind the submission, which is important when the EOI feeds into a competitive or audited selection process.

When to use a expression of interest

Responding to an open EOI or registration-of-interest call before a tender stage
Registering interest in a panel, supplier list or pre-qualification process
Applying to be shortlisted for a project, grant or partnership opportunity
Confirming intent to participate before committing resources to a full proposal

What to include in a expression of interest

Applicant details: legal name, ABN and contact person for the submitting organisation
Opportunity reference: the EOI title, reference number or process it responds to
Statement of interest: a clear declaration that the applicant wishes to be considered
Capability summary: brief relevant experience or capacity supporting the interest
Authorisation and signature: confirmation an authorised representative submits the EOI

Pros and cons of sending a expression of interest as a signing request

Pros

Captures a signed, dated confirmation of intent before the tender stage
Tracks whether the applicant opened and signed ahead of the deadline
Expiry keeps submissions aligned to the EOI closing window
Completion receipt gives a clean record the EOI was authorised and sent

Cons and things to watch

An EOI usually is not a binding offer and does not guarantee shortlisting
It does not replace the detailed proposal that follows at the next stage
Process owners may set strict format rules a signing tool cannot enforce
The signer must have authority or the submission may be set aside

Expression of interest FAQs

Is an electronically signed EOI valid in Australia?

Electronic signatures are generally accepted in Australia under electronic transactions legislation when the signer's intent and identity are clear and both parties agree to that method. Always check the specific EOI rules, which may set their own submission requirements, and seek professional advice if unsure.

Does signing an EOI commit me to bidding?

Usually not. An EOI typically registers interest rather than forming a binding offer, but the exact effect depends on the wording and the process rules. Read the EOI documentation carefully before submitting.

Who should sign the expression of interest?

The applicant or a person authorised to act for the organisation, such as a director or bid lead. Using an authorised signer helps ensure the EOI is accepted by the process owner.

Is my EOI kept private?

Yes. Cosign delivers the EOI through a private link to the named signer, and the pages are not indexed by search engines. Your commercial details are not made publicly searchable.

Can I set a deadline so the EOI is not signed too late?

Yes. You can set an expiry, such as 14 days, to align with the EOI closing date, and send reminders if the link has not been opened or signed.
