An estimate compliance tool specifying estimate compliance criteria is presented. The estimate compliance can be accessed via hardware, software or a combination thereof. The tool can be configured to include functions facilitating creation of rules that outline criteria for estimate creation or invoicing. A user can enter vehicle and parts identification via a user interface to which a rule will apply. The user can also enter a rule requirement or suggestion. The compliance tool can include multiple modules configured to accept user input regarding vehicle or parts criteria or configured to create an estimate compliance rule based on the vehicle or parts criteria. The compliance tool can further include a storage medium configured to store multiple estimate compliance rules and a profile module. The profile module creates a rules profile comprising multiple estimate compliance rules. Additionally, the tool provides a compatibility module that checks compliance rules for conflicting rule criteria.
