When we undertake a non-trivial project, we normally submit a statement of work that also includes our fees and other charges. Once you have agreed on the statement of work, no changes can be without the agreement of both parties. In most instance this results in a fixed price or a variable price that is dependent on a readily identifiable work unit. For example when we develop shopping carts we usually charge a fixed price per unit rather than an hourly rate. All rates are portal-portal and are for a minimum of two hours.
Payments are due upon receipt of the invoice.
We accept payments by check or major credit card. We subscribe to the open source standards-based approach to our projects. Normally we retain the copyright on all source code and documentation we develop under the terms of the GNU Public License. Under the terms of that license, you can use any code, documentation or other materials we develop for your project in any way that you want. But, you cannot sell it and you cannot remove our copyright statement.
