Potential barriers to purchasing consortia include confidentiality,inequality in the sharing of benefits,and loss of control.

Confidentiality concerns may arise if members of the consortia are competitors and sharing information could put them at a disadvantage. Inequality in the sharing of benefits could occur if some members contribute more or have more bargaining power, leading to an unfair distribution of benefits. Loss of control could occur if members have less autonomy in decision-making because they have to consider the interests of the consortium as a whole.
