−	An invitation to tender ~~may follow~~ an assessment of pre-qualification questionnaires (PQQs) received by the client in response to an advert they posted, and perhaps a pre-tender interview.	+	Before an invitation to tender is issued, tender documentation needs to be prepared describing what is required, and a list of prospective tenderers compiled who will be invited to tender. This might include an assessment of pre-qualification questionnaires (PQQs) received by the client in response to an advert they have posted, and perhaps a pre-tender interview with prospective tenderers.

−	The purpose of pre-qualification questionnaires and pre-tender interviews is to produce a shortlist of suppliers who are ~~deemed~~ most appropriate for the project and who will then be invited to tender. This avoids time being wasted preparing and assessing inappropriate tenders.	+	The purpose of pre-qualification questionnaires and pre-tender interviews is to produce a shortlist of suppliers who are considered most appropriate for the project and who will then be invited to tender.

−	~~NB For as long as~~ the UK is ~~in the EU, public projects~~ or ~~publicly-subsidised projects may be subject to OJEU procurement procedures~~, ~~enacted in~~ the ~~UK by [http~~:~~//www~~.~~legislation~~.~~gov.uk/uksi/2006/5/contents/made The Public Contracts Regulations]. The regulations set out rules requiring that contracts must be advertised in the Official Journal~~ of the ~~EU (OJEU) (The~~ requirements ~~for OJEU Contract Notices can be found at [http://simap~~.~~europa~~.~~eu/index_en~~.~~htm simap]~~). ~~This is of particular importance because~~ the ~~time taken~~ to ~~advertise contracts can be up to 52 days~~. ~~The regulations also describe allowable procedures for the selection of contractors~~.	+	= What happens after tenders are submitted? =
		+
		+	Once tenders have been received, a careful process of assessment must be undertaken to identify the preferred tenderer. This is known as tender evaluation (or sometimes, tender adjudication).
		+
		+	Typically, assessments might consider some of the following criteria:
		+
		+	* Price.
		+	* Relevant experience.
		+	* Understanding of the requirements.
		+	* Past performance.
		+	* Technical skills.
		+	* Resource availability.
		+	* Management skills and systems.
		+	* Proposed methodology (this might include mobilisation plans, design proposals, and non-compliant proposals if these have been allowed).
		+	* Compliance with the requirements set out in the invitation to tender.
		+
		+	For more information see: Tender evaluation.

−	~~NB: For private finance initiative (PFI) projects~~, ~~see Invitation to Negotiate~~.	+	This may be followed by a period of negotiation, before final terms of the contract are agreed.

−	~~NB The [https~~:~~//www~~.ungm.org/Areas/Public/pph/go01.html UN Procurement Practitioner's Handbook], produced by the Interagency Procurement Working Group (IAPWG) in 2006 and updated in 2012 defines an ‘invitation to bid’ as: ‘A formal method of solicitation where prospective suppliers are requested to submit a bid for the provision of goods or services. Normally used when the requirements are clearly and completely specified and the basis for award is lowest cost.’	+	For more information see: Tender negotiation.
