I only give general legal advice on forums and no attorney client relationship is established by my answers.
Generally, Limited Liability sections look something like this and describe the limits of your liability to the client:
LIMITATION OF LIABILITY
UNDER NO CIRCUMSTANCES, INCLUDING, WITHOUT LIMITATION, NEGLIGENCE, SHALL WE OR OUR PARENTS, SUBSIDIARIES, AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, OR SUPPLIERS BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES RESULTING FROM THE USE OR THE INABILITY TO USE ANY SERVICE OFFERED BY US, OR FOR THE COST OF PROCUREMENT OF SUBSTITUTE GOODS AND SERVICES, OR RESULTING FROM ANY GOODS OR SERVICES PURCHASED OR OBTAINED, OR MESSAGES RECEIVED, OR TRANSACTIONS ENTERED INTO BY MEANS OF OR THROUGH ANY SERVICE OFFERED BY US, OR RESULTING FROM UNAUTHORIZED ACCESS TO OR ALTERATION OF YOUR TRANSMISSIONS OR DATA, OR OTHER INFORMATION THAT IS SENT OR RECEIVED OR NOT SENT OR RECEIVED, INCLUDING BUT NOT LIMITED TO, DAMAGES FOR LOSS OF PROFITS, USE, DATA, OR OTHER INTANGIBLES, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. YOU ALSO AGREE THAT WE SHALL NOT BE RESPONSIBLE OR LIABLE TO YOU, OR TO ANYONE, FOR THE STATEMENTS OR CONDUCT OF ANY THIRD PARTY ON OR ARISING FROM USE OF ANY SERVICE OFFERED BY US. IF YOU ARE DISSATISFIED WITH ANY SERVICE OFFERED BY US YOUR EXCLUSIVE REMEDY IS TO DISCONTINUE USE OF THE SERVICE WITHOUT REFUND OF ANY KIND WHATSOEVER.
Further, your indemnification section is only as good as the creditworthiness of the client.
Finally, I encourage my clients to establish and run their business as an LLC as extra protection.
