The interface of this software it's very intuitive, easy and very useful especially when dealing with all purchase orders/suppliers' documents and bills (receipts).The best advantage here that they are completely open-source! It doesn't cost anything additional or is even free you can install them in your own computer. There isn’t much I dislike about this software since i have been using for almost 4 years now but maybe there should consider including other languages like Spanish and French as well when adding new versions of the software. The benefits we got here are mainly efficiency. For instance if one was working during his office hours he could check everything regarding purchases, invoices and receivables so that our organization will continue without being late paying bills due dates. I like that it's very user-friendly, as one does not need any training or formal education in order use this software; you just click here/there (depending where your problem lies) with ease! The only thing i dislike about cc 1 lab are those who do nothing but complain instead of solving their problems by using our product which will help them solve theirs issues without having complaints all over social media networks such us Facebook etc.,.
