Greeting card box organizer: diy

I knew I needed something to organize my greeting cards after I started finding them all over the place. So I found this kraft box at Hobby Lobby and I turned it into a greeting card holder/organizer. 

I have always loved being organized but I have realized how more important it is when you have a business. I just opened my Etsy business in January so it isn't big (yet) by any means but I know how important it is so stay on top of organization. Keeping track of sales, shipping cost/purchases, receipts, etc. Both my mom and dad are self-employed with different businesses and so I have seen first hand what it take to be successful and one major key is to stay organized. And this is just perfect for where I am at right now.

I made dividers with colored paper and I folded and stamped white card stock to make the tabs. I also make areas for receipts, envelopes, and stamps. This is working great for me so far and I know where to find everything I need when someone purchases a card. 

I think it in the future I will paint the outside of the box but for now I just decorated it with some misplaced pieces of washi tap.
What do you all think?
love, Carlee
