For podiatry there are tons of products that need to be sold to the client to complete their treatment. Does openEMR have facilities of handling that? I thinking that if I add them in as procedures with their accompanying price, they should be able to select them and add them to the patient record so that the reception area know what to charge them for.
Under Administration --> Globals --> Features you can select a drop down indicating you sell products. This activates the Inventory module where you can add the products and track them.
See http://www.open-emr.org/wiki/index.php/Pharmacy_Dispensary_Module for detailed instructions.
