Decent, but SLOW

The software itself is decent, but has a few annoying glitches (like checking off the “gst” checkbox doesn’t always turn it off, I have to click the “save” button twice to do anything, stuff like that), but I would have given four stars if it weren’t for how SLOW it is. It takes several minutes to save, and while I am saving it seems to take up every thread of memory my website has. I can’t do ANYTHING else while waiting for these invoices to save. Opening a PDF? Takes like 2 minutes. It’s a real pain in the butt, and interrupts my work flow quite a bit
