What is an Invitation to Tender (ITT)?

Also known as ITT, Invitations to Tender are formal documents issued by the buyer to invite suppliers or contractors to participate in the competitive bidding of contracts. The word required could be in the form of supply or service.

Following the standard tender process, it’s common that a pre-qualification questionnaire, PQQ, is required before the invitation to tender is sent. A process in which reduces potential service providers or suppliers to ensure the invitation to tender is sent to qualified businesses. Passing the PQQ stage provides a shortlisting of the best possible candidates.

What do Invitations to Tender usually include?

Each invitation to tender includes its own set of requirements for the sector and project specifications needed. However, the following documents can be expected:

  • Project overview
  • Technical requirements
  • Tendering procedure
  • Selection criteria
  • Terms and conditions of the contract

What do I provide in reply to an Invitation to Tender?

As the tendering supplier or service provider, responding to an ITT should include submission of the following documents: (dependent on project requirements, the following list contains common elements required)

  • Company profile
  • Technical proposal
