Conditional Acceptance A conditional assumption, sometimes referred to as qualified acceptance, occurs when a person who has received an offer informs the supplier that they are willing to accept the offer, provided that certain changes are made to their terms or that a condition or event occurs. This type of acceptance serves as a counter-offer. A counter-offer must be accepted by the original supplier before a contract can be concluded between the parties. The fact that there was no physical person responsible for verifying or intervening on any action carried out by the automated messaging system or the resulting contract is in itself an insufficient reason to invalidate a contract formed by the interaction of an automated messaging system and a natural person or between automated messaging systems. Therefore, a bidder cannot claim that the acceptance was not valid simply because the response generated by its automated messaging system was automatic and was not initiated by any individual on behalf of the bidder.  An invitation to treatment is not an offer, but an indication of a person`s willingness to negotiate a contract. It`s a pre-offer communication. In the UK, Harvey v. Facey is an indication to the owner of the property that he or she might, for example, be interested in a sale at a specified price, was considered an invitation to treatment. Similarly, in the English case Gibson v. Manchester City Council, the words “may be ready to sell” were considered a price notice and therefore not a separate offer, although in another case involving the same policy change (Manchester City Council experienced a political change and stopped the sale of council houses to their tenants) Storer v. Manchester City Council “ the Tribunal found that an agreement had been the signing and restitution of the sale contract by the tenant, because the language of the agreement was sufficiently explicit and the signing on behalf of the Council was a mere formality to be fulfilled. Invitation declarations serve only to collect offers from individuals and not to result in an immediate binding obligation.
Courts tend to be consistent in determining invitations to process proposed and accepted invitations in joint transactions. The display of goods for sale, whether in a display case or on the shelves of a self-service store, is generally treated as an invitation to processing and not as an offer.   No, the bidder`s silence cannot be considered an acceptance of the offer. This is due to the principle that acceptance must take the form of a definitive, concrete and unrestricted notification of the bidder`s intention to accept the contract in accordance with its specific terms.
