Limitation of Liability

STPA shall not be liable to the Client in contract or in tort for special, indirect, incidental or consequential damages such as but not limited to damage or loss of other property or equipment, loss of profits or revenue, loss of the use of equipment, cost of capital, cost of purchase or replacement equipment, or other claims of Client. There are no warranties, expressed or implied, in connection with the Agreement or the services to be performed hereunder. The Client agrees that STPA’s potential liability to the Client as a result of the services to be performed under the Agreement shall be limited to those direct losses or damages incurred by the Client as a direct and proximate result of errors, omissions and/or negligent acts of STPA, and that in no event shall STPA’s potential liability exceed One Million U.S. Dollars ($1,000,000.00).

If purchase orders require alternative terms and conditions, a Word copy of the terms and conditions shall be sent to STPA for editing to reach agreed upon terms and conditions prior to signature.

Credit Cards

STPA accepts Visa and MasterCard for payment. STPA applies an additional 3% surcharge for processing the credit card.


STPA bills only for services rendered and expenses incurred and will make every effort to minimize costs for the project. If the Client requests additional services outside the proposed Scope of Work, the amount invoiced by STPA and the equivalent amount paid by the Client would be greater than the total cost stated in the proposal. Billing is provided monthly and is accompanied by an itemized invoice. Payment shall be provided by Client within 30 days of receipt of the invoice.
