  • Hola amigos! Estoy iniciando con Unicenta oPos y tengo una necesidad. ¿Alguien me puede ayudar con el código para que en mi ticket agregue e imprima la referencia del producto? Por su atención, gracias.

  • Hello, I want to add another sum that will be in another currency, such as the first sum will be the dollar and the lower value in euros How can I do it and what is code

  • Beware of those reviews. I am sure most of them are biased or manipulated. I regret I trusted them, spend a month trying on this product on my small shop. It gets frozen many times. May be it was done intentionally so that people pay and get recent version. Isn't it copied and modified code over open bravo, isn't it got huge support form community. Then how come it sells the source and try to earn money? If jack was originator and copyright owner of full source code he could ask for money. Now selling code developing by user is just unethical. Stop these crocked business on opensource.

  • I Wish i could Rate this project -100 Stars as Unicenta used Open Source Software and Closed it for payment. GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free. This is a typical corrupted government way of doing things like using a tax payers build road and put a toll gate on it to gather money from it. Why did unicenta initiator then not close the source from the beginning? maybe because he needed help from community to build the solution. We should have some group or entity controlling these licenses of projects misusing it.

  • My Favorite Project! Thank you Jack for your wonderful project. I own two stores in NJ area. One of them sells Sandwich and other Pizza. I used open bravo and then Unicenta made me more happy. Its best for Light retail and quick service. For my second store, that has dine in and home delivery, I use Floreant POS. Both use Java and MySQL so they coexists. Thank
