An invitation to treat is a legal concept that refers to an indication that a party is open to receiving offers, but it is not an offer in itself. Common examples include advertisements, display of goods in shops, or issuing a tender. It invites others to make offers, which may or may not be accepted.
Reference:CIPS L4M3 Commercial Contracting Study Guide, Chapter 1, Section 1.2.1 - The formation of a contract including offer, acceptance and invitation to treat.

Without further explanation, a schedule may be deemed to form an integral part of the obligations of either or both parties. Obviously, the scope or binding nature of such schedule depends on the way it is referred to in the obligatory language of the main agreement. Accordingly, merely attaching the general terms and conditions of sale without explaining to which part of the sale they apply or which provisions apply does not subject a sale pursuant to the body text of the agreement to those general terms and conditions.
Subcontracting is the practice of assigning, or outsourcing, part of the obligations and tasks under a contract to another party known as a subcontractor.

These categories are: freedom of association and the effective recognition of the right to collective bargaining, the elimination of forced or compulsory labour, the abolition of child labour and the elimination of discrimination in respect of employment and occupation.

* Confidentiality (1) - protects sensitive information.
* Variation and price adjustment (4) - allows controlled changes to scope and pricing over time.
