Admission Fees paid to courthouses, repositories, and other record facilities. Methods of payment vary. The genealogist then works and bills against the retainer until it is spent. Then, another retainer is paid and work continues. In other cases, a genealogist may consume the retainer, work to a stated budget agreed to by the genealogist and client, and then bill the client for the difference.
Some genealogists simply bill as they work.
Others charge a daily rate or charge a flat fee per project. These payment methods are less common than the retainer system, however. You, as a client must be clear with yourself and your researcher as to what the billing arrangement should be. Break a large project into smaller tasks and pay periodically. Request frequent reports and detailed billings to keep you informed.
