Hello...


Seeking ready-made, ready to go USA payroll system for all 50 states OR payroll from scratch. Must include:


API integration with our GPS admin using hours and miles from GPS app

Cloud based

Direct deposit and check printing

Able to file/pay state/federal taxes electronically for all 50 states

Able to obtain all 50 US state/local payroll tax information as well as federal payroll tax information


We understand that some freelancers will suggest that we use 3rd party sources such as Gusto, ADP, etc. That is fine, as long as we know the following:


Cost to integrate with our GPS admin. This GPS admin was built in house using PHP

Monthly cost to process payroll per employee

Automatic updates for all 50 states and federal taxes.


We would like a listing of milestones for the project, and the length of the project. Payroll software will be the property of our company so we may offer our own payroll services as a white label
