Provided are computer implemented methods and systems for selling products and services using crowdsourcing. An exemplary method comprises receiving information associated with a crowdsourcing item. The crowdsourcing item is associated with an owner of the crowdsourcing item. The information includes a target amount for crowdsourcing. One or more contributions associated with the crowdsourcing item are received from one or more users. The total amount of the contributions is periodically calculated. When determined that the total amount has reached the target amount, the total amount is transferred to the owner. Additionally, the crowdsourcing item may be produced by the owner using the contributions and delivered to the users who made contributions either by one item to each of the users or by a share of the crowdsourcing item proportional to the contribution made.
