I use FileMaker Pro Database to stay organized. I run separate data bases for books and Gems. Each item is assigned an inventory number automatically.
Beginning as a book seller, I had shelves upon shelves of books. Each book case has a letter and a shelf location. I have carried this further to the clear plastic shoe boxes, where I store smaller items.
Location DA1-1
Would be
D- Diningroom
A- Book Case A (lettered right to left)
1- shelf 01 (numbered top to bottom)
-1 -box 1 (I have one red box the location then is DA1-red)
One book case has 13 shelves hence the - before box.
This has helped me move 2500 book titles and all my items "Gems" for sale in an organized fashion. Yes we located to a new home 9 months ago and will be relocating again in 1-2 months. Some items I store in Filing cabinets this has the same system.
I use these bags for clothing and fabric

to list on. One site I have to do all the coding for Google searches. The data base allows me to create formulas to create the coding for google. I also use this to create keywords
I can also use it for creating supplies for each item, and supplier. The pull up a list of what sold in a certain period to show, what I have used and need to replace.
Not all of my items qualify to list on Etsy.
I have create check boxes for each shop I sell in so I can see what is for sale where. This way when I sell and item I can close the listing in other places.
one option is "do not list on Etsy" to prevent me from listing non vintage.
At one time I had over 12,000 book titles for sale. Some books I had 100 copies of. without organization I would never have made it.
I just began listing on Etsy this year. I love Etsy it is much simpler to use.
