There is NOTHING we can help you with in 4POS that has not been posted yet!
4POS is also the ONLY POS software that has this type of knowledgebase available. I suspect all the other POS companies want you to call them, take out a service contract or send a tech to site at plenty $$$!!!
We want you to help yourself!
