How to best manage inventory for various live "makers market" events

Hi, so I have an online store with no real “brick and mortar” storefront, My default location is. “Home” However, I have started doing live market events, and I use the Shopify POS to process sales at these markets. I’ve been doing it this way but the last time I did this my website showed everything as Sold Out. This is how I’ve been doing it, and I wonder if there’s a better way. It’s tideous as I usually have 50+ products and I cant find a way to “select all”

  1. Transfer from Home to “market location”. I have to manually select each product and go thru multiple steps to send/receive. I always check the box to “alllow products at this location to be sold online”

  2. Transfer from “market location” to Home. Follow the same steps at in step 1.

  3. Do the same for the next location and continue “transferring my inventory” from home to these markets.

I want to be able to see sales at these locations to compare data.

Is there a better way?

Any idea why my inventory showed as Sold Out?

Any tips would be really appreciated, this is all still very new.

Thanks in advance!
