The best thing about this program it's simplicity! It makes managing my galleries so much easier than trying do them manually in Excel or Word documents with all their different tabs for each category (like shipping/invoices). I have not encountered anything yet as far too dislike at least nothing major but maybe some minor things like when adding invoicing options sometimes they don't show up right away until after refreshing which isn’t always possible if there are other items open already etc., however these issues aren;' really big enough concerns since we've been using artfundi exclusively now over 2 years without any problems what-so ever!! We're able ship our paintings straight out into storage boxes via UPS rather then having people pick ours off site by hand every time because its just more efficient & accurate overall plus saves us money due less packaging costs ect..
