Invitation to Tender

An Invitation to Tender is used when the buyer can describe exactly what it wants — a defined quantity of a defined item, or construction to a completed design. Because the specification leaves little room for interpretation, there is little to evaluate beyond compliance and price.

The practical consequence is that ITTs are usually awarded to the lowest compliant bid. Compliance is binary: a bid that misses a mandatory requirement is set aside regardless of how attractive its price is. This makes ITTs unforgiving of administrative error — an unsigned form or a missing certificate ends the bid as surely as a bad price.

For suppliers, ITTs reward operational efficiency rather than persuasive writing. If your cost base is not competitive for the specified work, no amount of proposal quality will change the outcome. That is useful information: it makes bid or no-bid decisions on ITTs faster than on RFPs.
