Hello, install the system and run very well. I have already tested their behavior and I have no complaints about it, it is very useful and with many functions. I go to the forum since I have several clients created but I can not generate an invoice for the client, I saw in some videos as in the client tab the option that says invoice, but in my case it does not go out, I attach the image.
I hope you can help me.
Thx in advance
